Movement testings are more reliable than other diagnostic methods in cervicogenic headache (CGH) but validity remains a question.
According to Haldeman S et al (2001) the notion that headaches may originate from disorders of the cervical spine and can be relieved by treatments directed at the neck is gaining recognition among headache clinicians.. There remains considerable controversy and confusion on all matters pertaining to the topic of CGH. However, the amount of interest in the topic is growing, and it is anticipated that further research will help to clarify the theory, diagnosis, and treatment options for patients with CGH. According to Frese A et al (2008) Upper cervical pain is frequent in different primary headaches and not sufficient evidence for cervicogenic headache (CGH). Biological markers should help to differentiate CGH from other headache disorders.
In most cases, imaging techniques of the cervical spine are not helpful for the diagnosis of CGH.
Symptoms and signs of neck involvement, such as a mechanical precipitation of attacks, a restriction in range of motion of the cervical spine, and the existence of ipsilateral neck, shoulder, or arm pain, seem to be reasonably valid for the diagnosis of CGH, but its reliability and validity should be confirmed in larger studies.
Positive diagnostic blockades of cervical structures or its nerve supply are not specific for CGH. Neurophysiological investigations give some insight into the pathophysiological mechanisms of CGH but are not diagnostic. In CGH, calcitonin gene-related peptide levels do not differ between the symptomatic and the asymptomatic side, between the jugular and the cubital blood, and between days with and without headache. There is no evidence for an activation of the trigeminovascular system in CGH. It can be concluded that CGH is not just a migraine variant triggered by neck dysfunction but a functional entity.
Until then, it is essential that clinicians maintain an open, cautious, and critical approach to the literature on cervicogenic headaches.

By controling weight this diabetes can be prevented by rational food intake & daily exercise regimen.
Many studies have attributed rapid urbanization in all most all parts of the world with associated with change in multiple factors favorable of obesity development. One of the foremost factors that come to mind is enhanced mechanization & gadget usage has lead to over all reduction in day to day caloric expenditure in physical activity. Migration to such an environment leads to obesity.

Over the past two decades, it has become accepted that the rotator interval is a distinct anatomic entity that plays an important role in affecting the proper function of the glenohumeral joint. The rotator interval is an anatomic region in the anterosuperior aspect of the glenohumeral joint located between the distal edges of the supraspinatus and subscapularis tendons and contains the insertions of the coracohumeral and superior glenohumeral ligaments. These structures form a complex pulley system that stabilizes the long head of the biceps tendon as it enters the bicipital groove of the humeral head.
Lesions of the rotator interval may result in
1. Glenohumeral joint contractures- adhesive capsulitis
2. Shoulder instability
3. Anterosuperior internal impingement.
4. Lesions to the long head of the biceps tendon.
1. Bone impingement,
2. Soft tissue impingement and
3. Entrapment neuropathy, depending on what impinges on the others.
Examples: The most important impingement syndromes of the upper and the lower limbs from the clinical viewpoint are as follows.
In the upper limb:
1. Supraspinatus impingement is a frequent cause of shoulder pain in both athletes and the normal population; the painful subacromial arch is a typical sign of the rotator cuff impingement syndrome and of outlet and non-outlet impingement as well.
2. As for the elbow, both medial and lateral impingement.
3. The carpal tunnel syndrome is the most common peripheral entrapment neuropathy of the upper limb; it is caused by compression of the median nerve at the wrist.
In the lower limb:
1. Iliotibial band friction syndrome, which is the most common overuse syndrome of the knee and the ankle impingement syndrome.
2. The latter includes anterolateral impingement (with chronic anterolateral and lateral pain and ankle instability), sinus tarsi impingement, anterior impingement (with pain during foot dorsiflection and posterior impingement.
3. The tarsal tunnel syndrome is the most important ankle entrapment neuropathy causing burn pain and paresthesias in the toes and sole of the foot.
Considered to be most often the result of a degenerative process at the origin of the plantar fascia at the calcaneus, Plantar fasciitis is a common cause of heel pain, which frustrates patients and practitioners alike because of its resistance to treatment. However, neurogenic and other causes of subcalcaneal pain are frequently cited. A combination of causative factors may be present, or the true cause may remain obscure. Approximately 10% of patients with plantar fasciitis have development of persistent and often disabling symptoms. Plantar fasciitis has been associated with obesity, middle age, and biomechanical abnormalities in the foot, such as tight Achilles tendon, pes cavus, and pes planus.
Management strategies are:
Nonsurgical treatment is ultimately effective in approximately 90% of patients. Nonsteroidal anti-inflammatory drugs, rest, pads, cups, splints, orthotics, corticosteroid injections, casts, physical therapy, ice, and heat.
Targeting tissue specific stretching: A poor response to treatment may be due, in part, to inappropriate and nonspecific stretching techniques. A recent study concluded, program of non-weight-bearing stretching exercises specific to the plantar fascia is superior to the standard program of weight-bearing Achilles tendon-stretching exercises for the treatment of symptoms of proximal plantar fascitis.

Reliability of the Ely's test for assessing rectus femoris muscle flexibility and joint range of motion.
Go through the following article by Dolny DG et al (2008):
WBV platforms produce frequencies ranging from 15-60 Hz and vertical displacements from ~1-11 mm, resulting in accelerations of ~2.2-5.1 g.
1. With WBV training, younger fit subjects may not experience gains unless some type of external load is added to WBV exercise.
2. However, sedentary and elderly individuals have demonstrated significant gains in most measures of muscle performance, similar with comparable traditional resistance exercise training programs.
3. WBV training also has demonstrated gains in flexibility in younger athletic populations and gains or maintenance in bone mineral density in postmenopausal women.
4. Acute exposure to WBV in sports persons has produced mixed results in terms of improving jump, sprint, and measures of muscle performance.
I always had thought stretching prior to explosive work out put is not prudent. Studies are confirming my way of thinking:
LaRoche DP et al (2008) of Department of Kinesiology, University of New Hampshire, Durham, New Hampshire, USA. firstname.lastname@example.org did a study was to determine whether muscle force, power, and optimal length were affected by 4 weeks of static or ballistic stretching.
The study suggested:
1. Individuals can routinely stretch following exercise to maintain flexibility but should avoid stretching prior to exercise requiring high levels of muscle force.
2. Before exercise that requires high muscular forces, individuals may perform dynamic, sport-specific exercises to increase blood flow, metabolic activity, temperature, and compliance of the muscle.

A review of Hambrecht R throws a light on how sports physical therapy has been accepted as a treatment.
Over the last 2 decades the clinical application of physical exercise as a therapeutic strategy has developed from rehabilitation to prevention and treatment of cardiovascular diseases. This shift in clinical application was accompanied by a more systematic research approach of the involved mechanisms and the objective clinical assessment of sport interventions using prospective randomized clinical trials. This ongoing process established physical exercise as an evidence-based and guideline-oriented treatment option.
1. In stable coronary artery disease (CAD), exercise therapy has long been used for rehabilitation purposes following an acute myocardial infarction. A recent meta-analysis revealed a significant 27% reduction of total mortality among training patients. Four mechanisms are considered important mediators of the reduced cardiac event rate: improvement of endothelial function, reduced progression of coronary lesions, reduced thrombogenic risk, and improved collateralization.
2. In stable chronic heart failure (CHF), physical activity was traditionally discouraged-with negative consequences for the patients: exercise intolerance worsened, the progression of disease-related muscular atrophy accelerated. A carefully designed exercise program at 50-70% of the maximal oxygen uptake was effective in improving exercise capacity by 12-32%. In a recent meta-analysis, exercise therapy reduced the relative risk of CHF mortality by 35% and CHF-related hospitalizations by 28%.
3. Considering the growing body of evidence in favor of sport as a therapy, training interventions should be considered additional/alternative therapeutic strategies as compared with established pharmacological/interventional options.
HIV-infected persons often experience a loss of lean tissue mass, which includes decreases in skeletal muscle mass. This HIV-associated wasting is significant because it has been associated with accelerated disease progression and increased morbidity.
In an attempt to counter muscle wasting in HIV-infected persons, treatments have been suggested that target these mechanisms. Nutritional supplementation, cytokine reduction, hormone therapy and resistance exercise training are potential treatments for this condition.
Resistance exercise training, which is more easily accessible to this population than other treatments, holds promise in counteracting the process of HIV wasting, as it has been successfully used to increase lean tissue mass in healthy and clinical populations.
According to Rhee JM et al (2007):
1. Cervical radiculopathy is a disorder involving dysfunction of cervical nerve roots that commonly manifests as pain radiating from the neck into the distribution of the affected root.
2. Acute cervical radiculopathy generally has a self-limited clinical course, with up to a 75% rate of spontaneous improvement. Thus, nonsurgical treatment is the appropriate initial approach for most patients.
3. When nonsurgical treatment fails to relieve symptoms or if a significant neurologic deficit exists, surgical decompression may be necessary.
4. Surgical outcomes for relief of arm pain range from 80% to 90% with either anterior or posterior approaches.

Non-articular conditions (NAC) cause the majority of painful conditions rather than articular ones in mid age and elderly. NACs appear to be common in older adults with knee pain. They make a significant contribution to knee pain severity and functional limitation and are likely to represent additional, rather than alternative, causes of knee pain/functional limitation to osteoarthritis (OA).
Today patients often need devices for more than one condition, and consideration must be given to the interaction between them. The use of transcutaneous electrical nerve stimulation (TENS) for pain relief is increasing. At the same time the implantable cardioverter defibrillator (ICD) is a routine treatment for malignant tachyarrhythmias.
Researchers have reported undersensing of ICD device while co-working with TENS. This might prevent the ICD from delivering shock when it should. Because of the potentially serious consequences of interference do not recommend the use of TENS in patients with ICD.
The piriformis syndrome is one of the non-discogenics causes of sciatica. It results from the compression of the sciatic nerve (SN) by the piriformis muscle (PM) in the neutral and piriformis stretch test position. Following are important things to know about it.
1. The location of the sciatic nerve with respect to consistent bony landmarks: mid way between the greater & the ischial tuberosity.
2. The test position is: 30 degrees adduction 60 degrees flexion and approximately 10 degrees medial rotation position of the hip joint.
3. Morphometric data suggest that after stretch test position, the infrapiriforme foramen becomes narrower; the SN becomes closer to the ischial spine of the hip bone, and the angle between the SN and the transverse plane increases.
A case I saw toay (18.6.2008): Today a 14 year old girl came to me with complain of stiff hip. All the movements ware severely limited. Her parents told that in 2006 dec she suddenly suddenly complained of hip pain. They could not tell any thing on fever. Radiographs showed reduced joint space, irregular joint margin, decreased neck length, osteoporosis in the head and neck of femur. She has been diagnosed with 4 different diseases by 4 different doctors:
1. LP disease
2. tubercular arthritis
3. septic arthritis
4. transient synovitis
Following is a topic for 1st hand physiotherapists for quick referrals. Children with a painful hip present a diagnostic challenge since clinical differentiation between septic arthritis, transient synovitis and Perthes disease may be difficult. Septic arthritis, a potentially life-threatening and debilitating medical emergency, requires early recognition for successful treatment, while transient synovitis and Perthes disease may be managed conservatively. An "ideal" single test for discrimination between these conditions is currently not available.
Because of the very severe nature of the of septic arthritis we are focusing on diagnosis of septic arthritis only.
Kocher et al. septic arthritis diagnosis is based on four clinical variables:
1. History of fever,
3. An erythrocyte sedimentation rate of >or=40 mm/hr,
4. And a serum white blood-cell count of >12000/mm(3) (>12.0 x 10(9)/L).
Many other researchers found these criteria may not good enough for diagnosis. Few other researchers found following criteria helpful for diagnosis of septic arthritis.
All children with septic arthritis had hip effusion shown by ultrasound and at least two of the following criteria: fever, elevation of erythrocyte sedimentation rate (ESR) and of C-reactive protein (CRP). None of the children without effusion on ultrasound or who lacked two or all criteria had septic arthritis. Radiographs had no significant impact on the decision-making in primary evaluation of acute hip pain.
Once the acuteness subsides physios should mobilize the joint. The presentation as late as the above mentioned case require more aggressive approach. An experienced clinician will decide which approach and which techniques are good for individual patients. I found Mulligan’s techniques very very helpful.

Neuropathic pain is a chronic pain syndrome caused by drug-, disease-, or injury-induced damage or destruction of sensory neurons within the dorsal root ganglia of the peripheral nervous system. Characteristic clinical symptoms include the feeling of pins and needles; burning, shooting, and/or stabbing pain with or without throbbing; and numbness. Hyperalgesia and allodynia are special kind of neuropathic pain that is provoked by mechanic or thermal stimuli. Periphery mechanisms of neuropathic pain include hyperexcitability of cell membrane and periphery sensibilization. Central mechanism includes central sensibilization, central reorganization of alphabeta fibers and loss of inhibition mechanisms.
Mononeuropathy, plexopathy, radiculopathy, and myelopathy, lesions of thymus, cortex or brain stem are real cause of neuropathic pain. There is no adequate adaptation and produce suffering without biological helpfulness. The aim of treatment of patient with neuropathic pain is soothing of pain and suffering and prevention of further development of pathological process.
Although the primary goal is to alleviate pain, clinicians recognize that even the most appropriate treatment strategy may be, at best, only able to reduce pain to a more tolerable level.
1. 1st line drug treatment: tricyclic antidepressants, antiepileptic drugs, topical antineuralgics, analgesics. If a patient does not respond to treatment with at least 3 different agents within a drug class, agents from a second drug class may be tried.
2. 2nd line of treatment: narcotic analgesics or refractory treatment options may provide some benefit.
3. 3rd line of drug treatment: Patients who do not respond to monotherapy with any of the first- or second-line agents may respond to combination therapy. But Carbamazepin was the drug of choice till ten years ago. Since then the leader position in treatment has belong to gabapentin in dose from 900-2400 mg daily. Currently the new drug is tested, antiepileptic pregabaline. The first experiences are promising.
4. If all of the above steps fail then candidate is a fitting case to be referred to a pain clinic. Because the techniques used at pain clinics tend to be invasive, referrals to these clinics should be reserved for patients who are truly refractory to all forms of pharmacotherapy.
Neuropathic pain continues to be one of the most difficult pain conditions to treat. A pain treatment protocol appropriate for each patient should be designed. The algorithm will also help streamline referrals to specialized pain clinics, thereby reducing waiting list times for patients who are truly refractory to traditional pharmacotherapy.
A comparison of pharmacotherapy with physiotherapy!
Physical therapy especially in the form of electromodulation of pain is the alternative or adjunct of pharmacotherapy. For example TENS can modulate primary order neuron relay of pain. And again it also can help produce beta endorphin to modulate secondary order neuronal relay of pain. Prudent applications of tens duration, frequency are sought so that both the effects could be gained in one sitting of physiotherapy. In my opinion TENS parallels the first three steps of pharmacotherapy.
Thalamic pain was first described 100 years ago by Déjerine and Roussy and has been described as "among the most spectacular, distressing, and intractable of pain syndromes".
Central poststroke pain (CPSP), formerly known as thalamic pain syndrome of Déjerine and Roussy, is a central neuropathic pain occurring in patients affected by stroke.
It is one manifestation of central pain, which is broadly defined as central neuropathic pain caused by lesions or dysfunction in the central nervous system.
CPSP is characterized by:
1. Constant or intermittent pain and is associated with sensory abnormalities, particularly of thermal sensation.
2. The pain is frequently described as burning, scalding, or burning and freezing, other symptoms are usually vague and hard to characterize, making an early diagnosis particularly difficult.
3. Those who develop CPSP may no longer be under the care of health care professionals when their symptoms begin to manifest, resulting in misdiagnosis or a significant delay before treatment begins.
4. Patients may also exhibit spontaneous dysesthesia and the stimulus-evoked sensory disturbances of dysesthesia, allodynia and hyperalgesia.
Diagnosis is complicated by cognitive and speech limitations that may occur following stroke, as well as by depression, anxiety and sleep disturbances.

Results indicated that:
1. although there was a significantly greater lack of knee extension on the injured side compared to the non-injured side in all three foot and ankle positions, knee extension was most restricted in the PFI position, which is considered to bias the common peroneal tract.
2. The slump test in PFI produced symptoms in the lateral aspect of the lower leg and ankle extending slightly anteriorly and posteriorly and into the dorsum of the foot. This distribution corresponds to that of the superficial peroneal nerve.
3. The slump test in neutral and DF produced areas of response similar to each other, which included the posterior aspect of the knee, thigh and calf. The release of cervical flexion resulted in a significant reduction in symptoms in each test.
These results may indicate altered neurodynamic function following ankle inversion sprain, and have implications for assessment and treatment of subjects with ankle sprain.
Published in journal of manual therapy(1996)
Mew medical hypothesis- Spinal manipulation and spinal mobilization influence different axial sensory beds.
Manipulation and mobilization are two forms of manual therapy commonly employed in the management of musculoskeletal disorders. Spinal manipulation and mobilization are often distinguished from one another by reference to certain biomechanical parameters such as peak force, duration and magnitude of translation. However, as of yet, there is relatively little research which distinguishes between them in terms of neurological mechanisms or clinical effectiveness. Theories concerning the mechanisms underlying the therapeutic effects of manipulation and mobilization commonly make reference to mechanical events such as the release of entrapped tissue or the disruption of intra-articular adhesions. Relatively less attention is given to neural effects.
This article hypothesizes that:
1. At least in part, spinal manipulation preferentially influences a sensory bed which, in terms of anatomical location and function, is different from the sensory bed influenced by spinal mobilization techniques.
2. More specifically, it also hypothesize that manipulation may particularly stimulate receptors within deep intervertebral muscles, while mobilization techniques most likely affect more superficial axial muscles.
3. In part, rationale for this hypothesis is based on differences in mechanical advantage of the respective manual procedures on multi-segmental versus short intervertebral muscles.

High-velocity low-amplitude manipulation (HVLA) VS. Mobilization exercises in subjects presenting with mechanical neck pain.
Saturday, June 7, 2008
Commonly designated idiopathic neck pain and some primary headaches (ie, tension-type headache or migraine) fit the descriptions of referred pain originating in muscle trigger points (TrPs).
Some authors found that both muscle TrPs in neck-shoulder muscles and cervical joint dysfunctions contribute at the same time to neck pain perception.
Several recent studies reported that both tension-type headache and migraine are associated with referred pain from TrPs in the suboccipital, upper trapezius, sternocleidomastoid, temporalis, or superior oblique muscles.
Referred pain elicited by active TrPs mimics the pain areas observed during head pain attacks in these primary headaches.
Farnandez-De-Las- Penas C et al (2007) concluded in their of article that the pain profile of neck and head syndromes may be provoked referred pain from TrPs in the posterior cervical, head, and shoulder muscles.
Shoulder impingement symptoms of over head athlete:
(1) Acquired glenohumeral anterior instability,
(2) Loss of GH internal rotation range of motion, and
(3) lack of retraction strength. Based on recent literature,
The following guidelines should be used with impingement symptoms (as described above):
(1) Shoulder rehabilitation should be integrated into kinetic chain training, not only in the advanced phases of the athlete's rehabilitation, but from the initial phases;
(2) Both angular and translational mobilisations can be used in the treatment of acquired loss of glenohumeral internal rotation range of motion to stretch the posterior structures of the glenohumeral joint; and
(3) In the rehabilitation of scapular dyskinesis, the therapist should focus on restoration of trapezius muscle balance in the scapular exercises, with special attention to strength training of the retractors.
Suggestion of chemical factor involvement comes from a number of clinical observations:
1. Disk surgery does not consistently provide pain relief,
2. Large disk herniations are not always symptomatic,
3. Severe pain may be present in patients without imaging evidence of nerve root compression,
4. The severity of symptoms and neurological signs is not well correlated with the size of the disk herniation, and conservative therapy is often effective.
Experimental studies have provided further evidence for a chemical component:
1. Disk herniations can undergo spontaneous resorption,
2. The intervertebral disk is immunogenic,
3. And mediators for inflammation have been identified within intervertebral disk tissue.
The current pathophysiological theory incriminates proinflammatory substances secreted by the nucleus pulposus (NP). When preexisting or concomitant mechanical injury to a nerve root occurs, these substances can cause nerve root pain.
Available information points to tumor necrosis factor-alpha (TNF-alpha) as the main candidate among substances potentially responsible for nerve root pain. Therefore, trials of TNF-alpha antagonists in patients with disk-related sciatica are warranted.
People just use their concept of decreasing the calories but they do not realize that they can harm themselves through their own way of fixing their calories. We must take the calories required by us to do the work throughout the day and in order to do that we must eat a balanced diet, but when people start eating less this will cause them to feel fatigued and weak and they tire pretty easily and thus are unable to perform the tasks at hand. Not eating properly also predisposes a person to suffer through infections and results in a weak immune system.

Indeed, Williams and his group have shown overweight men who exercised for one year (with or without diet), 25-50 min per session, 3-5 times per week reported:
1. increased LDL peak flotation rate,
2. as well as LDL peak particle diameter, and
3. decreased small LDL mass concentrations in plasma despite no change in mean plasma LDL-C concentration.
Hence lack of change in plasma LDL-C levels may not always adequately reflect changes in LDL concentration and distribution as exercise training may induce simultaneous changes in small LDL, large LDL and IDL-cholesterol levels.
1. Most training studies have not been designed to investigate the effect of exercise on body fatness, but rather to investigate the potential metabolic effects of exercise training and its relation to cardiovascular disease risk.
2. And in many of these exercise training protocols, there was no control of subjects' caloric intake.
These two factors have obviously a considerable impact on the potential reduction of body weight following endurance exercise training and may therefore be partly responsible for the equivocal results reported.
do not expect to loose weight with cardio protocol- you need to be aggrasive yet safe with the protocol formulation
Obesity increases the risk of serious co-morbidities such as type 2 diabetes, cardiovascular disease, certain cancers and reduced life expectancy, and these complications may account for 5-10% of all health .
The risk of diabetes is particularly increased by obesity, and 80-95% of the increase in diabetes can be attributed to obesity and overweight with abdominal fat distribution.

The results show that
In male subjects under sedentary conditions, 24-hour fat oxidation is positively related to body fat mass and negatively related to VO2max (the marker used here for level of physical fitness). This supports our hypothesis that regularly active males maintain lower body fat stores as the low contribution to daily fat oxidation from a lower body fat mass is counterbalanced by the high contribution to fat oxidation from daily physical activity.
The lack of a relationship between VO2max and 24-hour energy expenditure under the sedentary conditions of this study suggests that the major effects of physical activity on total daily energy expenditure and fat oxidation may occur during and relatively quickly after an exercise bout. Further, cessation of regular exercise will likely be associated with a high risk of positive fat balance and weight gain.

obesity -3 / “Exercise leading to fitness and weight management” is a reflection of body’s metabolic statement to exercises:
2. There is convincing evidence of susceptible individuals fail to compensate for periodic fluctuations in energy expenditure and become obese.
3. The major dependent variable that needs to be examined in relation to the cause of obesity is not energy expenditure but change in energy balance over time and the ability to regulate body energy stores.
obesity topics 1-treatment of obesity are discouraging for doctors, other health professionals and patients

The treatments subjected to analysis are: oral NSAIDs, psychotropic agents, steroid injections, and anaesthetic agents.
1. For acute whiplash, administering intravenous methylprednisolone within eight hours of injury reduced pain at one week, and sick leave but not pain at six months compared to placebo in one trial.
2. For chronic neck disorders at short-term follow-up, intramuscular injection of lidocaine was superior to placebo, treatment advantage 45% and dry needling, but similar to ultrasound in one trial each.
3. In chronic neck disorders with radicular findings, epidural methylprednisolone and lidocaine reduced neck pain and improved function more than when given by intramuscular route at one-year follow-up, in one trial.
4. In subacute and chronic neck disorders, muscle relaxants, analgesics and NSAIDs had limited evidence and unclear benefits.
5. In participants with chronic neck disorders with or without radicular findings or headache, there was moderate evidence from five high quality trials that Botulinum toxin A intramuscular injections had similar effects to saline in improving pain, disability or global perceived effect.
The conclusions are as follows:
1. Moderate evidence for the benefit of intravenous methylprednisolone given within eight hours of acute whiplash, from a single trial.
2. Lidocaine injection into myofascial trigger points appears effective in two trials.
3. There is moderate evidence that Botulinum toxin A is not superior to saline injection for chronic MND.
4. Muscle relaxants, analgesics and NSAIDs had limited evidence and unclear benefits.
1. Specific exercises may be effective for the treatment of acute and chronic MND, with or without headache.
2. To be of benefit, a stretching and strengthening exercise program should concentrate on the musculature of the cervical, shoulder-thoracic area, or both.
3. A multimodal care approach of exercise, combined with mobilisation or manipulation for subacute and chronic MND with or without headache, reduced pain, improved function, and global perceived effect in the short and long term.
4. The relative benefit of other treatments (such as physical modalities) compared with exercise or between different exercise programs needs to be explored.
The evidences they found are:
1. There is limited evidence of benefit that acute range of motion (AROM) may reduce pain in acute MND (whiplash associated disorder (WAD)) in the short term.
2. There is moderate evidence of benefit that neck strengthening exercises reduce pain, improve function and global perceived effect for chronic neck disorder with headache in the short and long term.
3. There is unclear evidence regarding the impact of a stretching and strengthening program on pain, function and global perceived effect for MND.
4. However, when this stretching and strengthening program focuses on the cervical or cervical and shoulder/thoracic region, there is moderate evidence of benefit on pain in chronic MND and neck disorder plus headache, in the short and long term.
5. There is strong evidence of benefit favouring a multimodal care approach of exercise combined with mobilisation or manipulation for subacute and chronic MND with or without headache, in the short and long term.
6. A program of eye fixation or proprioception exercises imbedded in a more complete program shows moderate evidence of benefit for pain, function, and global perceived for chronic MND in the short term, and on pain and function for acute and subacute MND with headache or WAD in the long term.
7. There is limited evidence of benefit on pain relief in the short term for a home mobilisation program with other physical modalities over a program of rest then gradual mobilisation for acute MND or WAD.
8. There was evidence of no difference between the different exercise approaches.
(1) Release of entrapped synovial folds or plica,
(2) Relaxation of hypertonic muscle by sudden stretching,
(3) Disruption of articular or periarticular adhesions, and
(4) Unbuckling of motion segments that have undergone disproportionate displacements.
Evans W (2002) reviewed is to critically discuss previous theories and research of spinal HVLAT manipulation, highlighting reported neurophysiologic effects that seem to be uniquely associated with cavitation of synovial fluid.
Evans W’s comments on 2 separate modes of action from zygapophyseal HVLAT manipulation:
1. Intra-articular "mechanical" effects of zygapophyseal HVLAT manipulation seem to be absolutely separate from and irrelevant to the occurrence of reported "neurophysiologic" effects.
2. Cavitation should not be an absolute requirement for the mechanical effects to occur but may be a reliable indicator for successful joint gapping.
So he concluded that, identification of these claimed unique neurophysiologic effects will provide enough theoretical reason for HVLAT manipulation. Thus manipulation & mobilization are to be assessed independently as individual clinical interventions.

Urban Life Versus Rural Life:
There is a huge difference between the Urban life and the rural life. In order to maintain our lifestyle and manage our expenses, we forget the most important thing, and that is us. We eat unhealthy and we do not exercise and this leads us to have excessive weight and it grows to such a level where it is difficult for us to manage it. On the other hand, if we analyze lifestyle in the rural areas, it is seen that people spend most of their time work on cultivation, so that they could eat and this is something that requires strenuous routines and keeps them fit and healthy throughout their lives and they encounter less medical problems than the people living in the urban areas.
The American College of Sports Medicine recommends that adults get 30-45 minutes of exercise three to five days each week, maintaining the intensity for the duration of the exercise. Each session should contains a 5-10 minute warm up and cool down period. If weight loss is a major goal, aerobic activity should at least 30 minutes a day for five days each week.
The National Association for Sport and Physical Education (NASPE) recommends at least 60 minutes, and up to several hours of physical activity per day for children and adolescents
Children should participate in several bouts of physical activity lasting 15 minutes or more each day
It is important to choose an activity that is fun so that motivation to continue the activity will remain high
Experts say people gain a lot of weight is not that they eat a lot; it is that they do not exercise. Simple things that are needed to ensure good quality exercise every single day are listed below:
1. Ensure high Quality Sleep: absence of sleep or sleeping less leads to lethargy & sluggishness the next day, we do no feel inclined to do exercises. So to ensure to have good exercise every day, it is really important that one gets a good sleep every night. So getting adequate sleep will be a major factor in achieving good quality exercise.
2. Walking Regimen: Brisk walk is a very healthy exercise regimen and can be done very easily. For this regimen, we advise that the people must use a jogging track to walk; as hard surfaces like concrete can affect weight bearing joints adversely, which in turn would result in cessation of your exercise plan. In order to start this program, it is healthy to start with a 30 minute program for five times a week. A brisk walk is recommended to lose weight is advised by a lot of health experts.
3. Treadmill Regimen: Machines like stationary bikes, treadmills etc helps us to carry out exercise routines and lose weight. Treadmill machines have a lot of features in which one can adjust the speed of the machine according to the exercise plan for that day. The other big benefit that one can get from the treadmill machine is that there are days when we do not have time to go out and exercise and we can utilize those machines and workout on that day so that the schedule is not broken. We can listen to some light music or watch television while executing our exercise plan during that.
4. Taking out Time for Our Own Health: people usually don’t have time for exercise, forgetting that they are doing everything on the basis of their good health that is keeping them going, and it is really odd that they do not have time for their own health. One must exercise every day and not stress self to a point where he have a “turn off feeling” from exercise. One must remember that good health is a blessing not only for him and but also for his family.
Histological characteristics of the deep fascia of the upper limb:
Specimens taken from the antebrachial and brachial fasciae demonstrated that fasciae are formed of numerous layers of undulating collagen fibre bundles. In each layer, the bundles are parallel to each other, whereas adjacent layers show different orientations.
Each layer is separated from the adjacent one by a thin layer of adipose tissue, like plywood. Many elastic fibres and a variety of both free and encapsulated nerve endings, especially Ruffini and Pacini corpuscles, are also present, suggesting a proprioceptive capacity of the deep fascia.
Specimens taken from different areas of upper limb [taken at the level of: (a) the expansion of pectoralis major onto the bicipital fascia, (b) the middle third of the brachial fascia, (c) the lacertus fibrosus, (d) the middle third of the antebrachial fascia, (e) the flexor retinaculum.] revel abundant innervation of the fascia consisting in both free nerve endings and encapsulated receptors, in particular, Ruffini and Pacini corpuscles.
However, differences in innervation were seen between retinaculum the more innervated element whilst the muscle (pectoralis major) expansions the less innervated. This suggests that the retinaculum has more a perceptive function whereas the tendinous expansions onto the fascia have mostly a mechanical role in the transmission of tension that confirms that the fascia plays an important role in proprioception, especially dynamic proprioception.
MRI study shows:
1. The clavicular part of the pectoralis major muscle sent a fibrous expansion onto the anterior portion of the brachial fascia, its costal part onto the medial portion and medial intermuscular septum. Thus the pectoralis major fascia always continues with the brachial fascia in two distinct ways: the fascia overlying the clavicular part of pectoralis major had an expansion towards the anterior brachial fascia, whereas the fascia covering its costal part extended into the medial brachial fascia and the medial intermuscular septum.
2. The latissimus dorsi muscle showed a triangular fibrous expansion onto the posterior portion of the brachial fascia. In the posterior region of the arm, the fascia of the latissimus dorsi sent a fibrous lamina to the triceps brachial fascia.
3. The posterior part of the deltoid muscle inserted muscular fibres directly onto the posterior portion of the brachial fascia, its lateral part onto the lateral portion and the lateral intermuscular septum.
4. The lacertus fibrosus was also composed by two groups of fibres: the main group was oriented downwards and medially, the second group longitudinally.
5. The triceps tendon inserted partially into the antebrachial fascia, while the extensor carpi ulnaris sent a tendinous expansion to the fascia of the hypothenar eminence.
6. The palmaris longus opened out into a fan-shape in the palm of the hand and sent some tendinous expansions to the flexor retinaculum and fascia overlying the thenar eminence muscles.
Function of Pectoral girdle muscles i.e. pectoralis major, latissimus dorsi and deltoid are connected not only through it’s muscular attachment to the humerus but also through the deep fascia i.e. the brachial fascia of arm. Hence during the various movements of the arm, these expansions stretch selective portions of the brachial fascia, with possible activation of specific patterns of fascial proprioceptors. It is hypothesized that the tendinous muscular insertions maintain the fascia at a basal tension and create myofascial continuity between the different muscles actuating flexion and extension of the upper limb, stretching the fascia in different ways according to the different motor directions.
Pathogenesis of pain from fascia:
1. The undulating collagen fibre bundles and elastic fibres, the fasciae can adapt to stretching, but this is only possible within certain limits, beyond which nerve terminations are activated by stretching. This mechanism allows a sort of "gate control" on the normal activation of intrafascial receptors.
2. The capacity of the various collagen layers to slide over each other may be altered in cases of over-use syndrome, trauma or surgery. In such cases, the mechanism of the fascia on the nervous terminations is lost, causing incorrect paradoxical activation of nerve receptors within the fascia, resulting in the propagation of a nociceptive signal even in situations of normal physiological stretch. At the same time, the layered collagen fibres allow transmission of tension according to the various lines of force. This structure of the muscular fascia guarantees perceptive and directional continuity along a particular myokinetic chain, acting like a transmission belt between two adjacent joints and also between synergic muscle groups.

In a study to define the innervation of the thoracolumbar fascia (in problem back pain patients who have articular abnormality defined through pain-provocation discography or facet blocks) found that the thoracolumbar fascia may be deficiently innervated in problem back pain patients. In this study sample collected from operating room (form lumbar spinal surgery patients) and later processed and studied under light and electron microscopy failed to identify specific neural end-organs in any of the specimens. Rather these samples show microscopic changes suggestive of ischemia or inflammation in this tissue were found.
But recent finding suggest otherwise. In addition to free nerve endings, two types of encapsulated mechanoreceptors (Ruffini's and Vater-Pacini corpuscles) were identified. These findings support the hypothesis that the thoracolumbar fascia may play a neurosensory role in the lumbar spine mechanism.
1. All patients were independently mobile, with restriction of internal hip rotation being the most significant clinical finding.
2. Valgus knees and pronated feet were typical associated findings.
