SMT biomechanics

Modern scientific investigations into spinal manipulative therapy (SMT) began in 1975. Conditions often treated include acute and chronic low back pain, radicular pain, neck pain, and some forms of headache. The field of spinal manipulation has often been treated by the literature, incorrectly, as being homogeneous. Much of the confusion regarding this form of treatment can be traced to the ambiguity surrounding the procedures themselves.

A categorization system for SMT was sought that would be more objective than is clinically available. Such a system may serve as a means to strengthen future studies, determine operating principles, applicability, treatment effectiveness, and nature of the manipulable lesion.
Attempt to classify SMTs:
Attempt to classify SMTs on biomechanical basis has been taken form different studies are as follows:
Studies that include measurements of mechanical characteristics of treatment techniques used under the general headings of SMT or manual therapy, studies exploring the biomechanics of buckling behavior of vertebral segments as a model of the manipulable lesion & quantitative characteristics of SMT were grouped to form a basis for classification.
These studies conclude:
There currently are a number of named systems of manual procedures. No current triage system is available that predicts which patient has the greater likelihood of benefiting from manual treatment or the procedure type. The biomechanical parameters of SMT form a systematic characterization of manual procedures. Such a system may be used in future studies to test hypotheses of treatment effect from quantitatively defined procedures.


  1. do you have the references for these, I would be curious to cross reference your articles to the ones I am collecting for an upcoming presentation I am doing on the topic. Thanks.

  2. sorry BO,
    i must have taken it from somewhere i felt authentic but forgot to mention the reference.
