Intersegmental motion

In the evaluation of the cervical spine for somatic dysfunction, the intersegmental motion between vertebrae is extremely important. There are several ways the cervical spine may be tested for individual vertebral motion. For all these methods, the patient will be supine with the physician seated at the head of the table.

Discrepancies in findings between areas ofthe thoracic spine (T1-T12, T1-T8, orTl-T4) may indicate an area of dysfunction and should prompt the physician to examine this area more closely with the techniques of rotoscoliosis testing and intersegmental motion testing, described later. 

Rotoscoliosis testing and intersegmental motion testing are two diagnostic modalities for evaluating somatic dysfunction at a vertebral level. They can be used alone or in conjunction with each other, according to physician preference. 

Intersegmental motion testing is another method of determining the motion between two vertebrae as one is moved on the other. This assists in determining motion restrictions involved in somatic dysfunction. 

Note that side-bending on intersegmental motion testing is greatly restricted by the ribs...
