Cervical: Observational studies

Abdulwahab SS, Sabbahi M, Neck retractions, cervical root decompression, and radicular pain., J Orthop Sports Phys Ther, Jan;30(1):4-9, 1999

In a group of patients with neck and radicular pain a posture of sustained flexion caused a significant increase in peripheral pain and root compression as measured by H reflex amplitude. Repeated retractions caused a significant decrease in peripheral pain and decrease of nerve root compression.

This was a retrospective chart review of 104 patients with cervical pain exhibiting direction preference (Cervical Derangements). The patients were treated by a chiropractor utilizing MDT. The study reported on the patient–related factors that predicted the responsiveness to treatment. Patient compliance, age>55, acute/subacute presentations and the experience of immediate symptom improvement were associated with a more successful patient outcomes.

Lam O, Dumas JP, Simon C, Tousignant-Laflamme Y, McKenzie mechanical syndromes coincide with biopsychosocial influences, including central sensitization: a descriptive study of individuals with chronic neck pain, J Man Manip Ther, Online Feb, 2018

This observational study looked at MDT classification of chronic neck patients at baseline and how they co-occured with some specific psychosocial measures. The majority of Derangements scored highly on these measures. Only baseline measures were taken, and thus the study was unable to determine if, as has been reported in the lumbar spine, psychosocial measures diminish with MDT management.

Case report of patients with cervical radiculopathy whose symptoms centralise with repeated retraction and rotation, and then are abolished with repeated retraction and extension. Numeric pain rating scale and Neck Disability Index are reduced to zero at discharge and 3 month follow-up.

Case report of woman with signs and symptoms of cervical radiculopathy and MRI showing a large disc herniation at the relevant level who was successfully treated with retraction extension exercises until she was symptom free. Shortly after this a repeat MRI showed a 56% reduction in the size of the herniation.
