12/3/2023 0 Comments Cervical range of motion norms![]() ![]() Measurement of the ROM at each vertebral segment requires a series of radiographs. Each of the methods described is indirect.With this method, the examiner must keep in mind that, in addition to the thoracic spine movement, movement also may occur in the lumbar spine and hips in fact, movement could occur totally in the hips. The examiner then measures from the fingertips to the floor and records the distance. An alternative test method involves having the patient bend forward and try to touch the toes while keeping the knees straight.Shoulder motion may be restricted if the upper thoracic segments or ribs are hypomobile. ![]() Any restriction of motion, excessive movement (hypermobility) or curve abnormality should be noted. Combined movements that may be tested in the thoracic spine include forward flexion and side bending, backward bending and side flexion, and lateral bending with flexion and lateral bending with extension. If the patient’s symptoms are highly irritable (easily aggravated), repetitive motion testing is not advisable. Repetitive motion testing depends partly on the patient’s irritability (i.e., the ease with which symptoms are aggravated). If the patient history indicates that repetitive motion, sustained postures, or combined movements aggravate the symptoms, these movements also should be tested however, this should be done only after the original movements of flexion, extension, side flexion, and rotation have been tested. The thoracic movements may be done with the patient sitting to reduce or eliminate the effect of hip movement. Likewise, tight hamstrings may alter the results. A patient can touch the toes with a completely rigid spine if the hip joints have sufficient range of motion (ROM). When assessing the thoracic spine, the examiner should be sure to note whether the movement occurs in the spine (thoracic or lumbar) or in the hips. They thus constitute reference data of cervical out-of-plane motion for clinical applications.Movement in the thoracic spine is limited by the rib cage and the long spinous processes of the thoracic spine. Our results agreed with previous observations, validating the methodology used. Sex had no influence on cervical motion range. Significant reduction of all primary (but not conjunct) motions with age were obtained. But heterolateral bending, averaging 60% of the primary motion, was associated to flexed rotation. During rotation in flexed head position, global range (134 degrees, SD: 24 degrees ) was comparable to the one in neutral flexion. Global rotation range in neutral sagittal plane position was 144 degrees (SD: 20 degrees ), without significant difference between right and left rotations. Its extent was approximately 40% of the bending range. Homolateral rotation was associated to lateral bending. Global bending range averaged 88 degrees (SD: 16 degrees ), left and right bending being comparable. Flexion was slightly more important than extension. In 250 subjects (aged 14-70 yr), motion range and patterns between the first thoracic vertebra and the head were analyzed for flexion-extension, lateral bending, rotation in neutral sagittal plane position and in full flexion using the CA 6000 Spine Motion Analyzer.Īverage motion range in the sagittal plane was 122 degrees (SD: 18 degrees ). In vivo out-of-plane motion patterns of the cervical spine have not yet been reported in large populations, but could be of clinical interest. Three-dimensional cervical motion ranges and patterns were analyzed in 250 asymptomatic volunteers. Establishment of a normal database and clinical reference of active global cervical spine motion ranges and patterns using a commercial electrogoniometer. ![]()
