Dystonia is a neurological disorder characterized by sustained or intermittent muscle contractions resulting in twisting, repetitive movements or painful postures. Cervical dystonia (CD), an isolated dystonia of the cervical musculature, can predispose the atlantoaxial joint to unstable changes. Symptomatic treatment of dystonia through local injections of botulinum toxin clearly reduces pain in most clinical settings. However, repeated chemodenervation of the involved muscles with neurotoxin is expensive and not available to the complicated cases of CD. In this report a 14-year-old girl with a 1-year history of CD complicated by atlantoaxial subluxation was treated using chiropractic intervention. As a result of this regimen, the girl reported a significant relief from the neck pain and torticollis after the first week. More gains of cervical range of motion were made over the course of 6 months of treatment. Chiropractic might have yielded some biomechanical responses linked to clinical effects. This case demonstrates an unexpected association between CD and atlantoaxial subluxation. In cases of CDs, atlantoaxial subluxation may be ignored but requires specialized treatment. An index of suspicion should be maintained for this rare but potentially debilitating complication.
This retrospective chart review was undertaken to investigate the role of chiropractic intervention for patients with adolescent idiopathic scoliosis (AIS). Ten cases of patients with AIS, mean age 13.3 years, undergoing chiropractic adjustment were retrospectively evaluated. Chart review was performed to extract age, medical history and treatment intervention. The magnitude of scoliosis was quantified using the Cobb method on standing radiographs. A comparison of the measurements from pre- and post-treatment radiographs revealed that Cobb angle reduced from average 29.7° down to average 23.4° (average 21.2% correction). Improvements in spinal morphologies were observed in most curves (64%, n=9/14) and curve stabilization in the rest (36%, n=5/14). A better correction was obtained in cases of mild and moderate AIS. In terms of stabilizing progression (≤5o curve progression) or correcting curvatures (≥6° reduction), radiological changes were observed in all patients.
