Many patients have difficulty properly activating this muscle and doing this properly. The neck can be stretched into flexion, rotation and lateral bending. 1. Clinical instability of the cervical spine is defined as the inability of the spine under physiological loads to maintain its normal pattern of displacement so that there is no neurological damage or irritation, no development of deformity, and no incapacitating pain. A 90 degree bend is quite enough to achieve a good stretch of the neck and actually more bend than I will ask of the horse in any Classical movements we will perform. Majority of the sounds are generated when the tight neck muscles cause the vertebrae (bones of the neck) to rub against each other when some movements are performed. Lateral Bending Can Help With Back Pain Over the last few weeks I've discussed low back spine extension and flexion exercises for back pain. Cervical spine in 0 0 of flex, ext, & rot. RESULTS: Mean maximum lateral bending of the cervical spine to one side was 1.6 degrees to 5.7 degrees at each level. The C1-C2 (atlantoaxial) joint forms the upper cervical segment, which allows for 50% of all cervical rotation. 378-386. Sitting, with thoracic & lumbar spine well supported by the back of the chair. In general, a doctor should be consulted if neck cracking, also called neck crepitus, accompanies any of the following: Following head and neck trauma, the involvement of the cranio-cervical junction (CCJ) and its contribution to a patients transition to chronic pain, is poorly understood. Cervical Rotation and Lateral Bending MMT - Duration: 2:48. Usually the strain on the vertebrae is caused by spasm (knots or cramps) of the trapezius muscle of the back or the sternocleidomastoid muscle of the neck. Tongue depressor can be held between teeth for reference. 2009 Jun 19;42(9):1177-92. doi: 10.1016/j.jbiomech.2009.03.029.  |  Lateral (flexion) Extension 25O Flexion 90O Left 25O Right 25O Degrees Degrees Degrees Degrees 3.
