static stretching related force output decrements!

-
When I did my PG thesis on “acute effect of static stretching on total CPK & margarita Kalamen test in female athletes” my primary aim was to decide whether static stretching related to reduction of force out put was due to physiological inhibition of muscle or due to reduced biochemical support (licking CPK enzyme) to working muscle that affects the immediate energy release. Holt BW et al (2008) compared the impact of different types of warm-up on countermovement vertical jump (VJ) performance. Sixty-four male Division I collegiate football players completed a pretest for VJ height. The participants were then randomly assigned to a warm-up only condition, a warm-up plus static stretching condition, a warm-up plus dynamic stretching condition, or a warm-up plus dynamic flexibility condition. VJ performance was tested immediately after the completion of the warm-up. The results showed that there was a significant difference (P < .05) in VJ performance between the warm-up groups. Posttest jump performance improved in all groups; however, the mean for the static stretching group was significantly lower than the means for the other 3 groups. The static stretching negated the benefits gained from a general warm-up when performed immediately before a VJ test.

Entrapment of medial calcaneal nerve (MCN)

Peripheral nerve entrapment is a rare, but important, cause of foot and ankle pain that often is underdiagnosed and mistreated. A peripheral nerve may become entrapped anywhere along its course, but certain anatomic locations are characteristic (2). The medial calcaneal nerve (MCN) The Tibial nerve is called the planter nerve in the sole. The tibial nerve passes to the sole of the foot takes a turn on the medial side of the calcaneum is called MCN. The medial calcaneal nerve arises from tibial nerve of the inner side of the ankle, perforates the laciniate ligament, travels downwards passing below the bony projection on the inner side of the ankle, and supplies the skin over the medial aspect of the heel. Hence it is the most important nerve for heel sensations. MCN have 2 branches. The anterior branch dominate the cutaneous sensation of the anterior part of the medial calcaneal and heel weight loading field, while the posterior branch dominate the sensation of the posterior an

Review of Labral Tears of shoulder

-
Image
The glenoid labrum of the shoulder has extensive anatomic variation but appears to be important for contributing to shoulder stability and for increasing the depth of contact between the glenoid labrum and the humeral head. Tears of the labrum are commonly seen in association with other pathologic entities, such as instability and rotator cuff tears, and treatment of the labral pathology may be incidental to treatment of the other more significant pathology. However, conditions isolated to the labrum do occur and can be a significant source of shoulder problems. Effective treatment of these lesions may result in significant improvement in the patient's symptoms (4). Labral lesions are difficult to diagnose, and special diagnostic studies and, frequently, arthroscopy are required. How much we can rely on clinical tests is a question. Shoulder complaints are frequently recurrent. Instability might cause some of these complaints (3). History taking and clinical tests are commonly used

Differential diagnosis of Anatomic (Radial) snuffbox pain: It is not always DeQuervain’s tenosynovitis.

-

Tendon, Bone & Ligament causes: 1. DeQuervain’s tenosynovitis: Swelling of tendon of APL (Abductor pollicis longus) & extensor pollicis brevis at lateral wrist near anatomic snuff box.  The primary complaint is radial sided wrist pain that radiates up the forearm with grasping or extension of the thumb. The pain has been described as a “constant aching, burning, pulling sensation." Pain is often aggravated by repetitive lifting, gripping, or twisting motions of the hand. Swelling in the anatomical snuff box, tenderness at the radial styloid process, decreased CMC abduction ROM of the 1st digit, palpable thickening of the extensor sheaths of the 1st dorsal compartment and crepitus of the tendons moving from the extensor sheath may be found upon examination. Other possible findings include weakness and paresthesia in the hand. Finkelstein’s diagnostic test will present positive provoking the patient’s symptoms. If left untreated, the inflammation and progressive narro
