 The investigators propose to use Vicon 3-dimensional gait and posture analysis to determine the biomechanics of subjects with primary cervical dystonia to compare with full body complaints from a standard spasmodic torticolliscervical dystonia questionnaire as well as the osteopathic structural exam. These measures will be assessed before and after four OMM treatments. In addition, the investigators propose to use osteopathic manual medicine along with botulinum toxin injection to improve the subjects pain and motor function as evaluated by Vicon 3-dimensional gait and posture analysis and questionnaire regarding quality of life. Preliminary case reports suggest that Osteopathic manipulative medicine without botulinum toxin injections improved pain, posture, gait, and quality of life in four adult subjects as well as improved head tilt in two children two- and five-years old. The central hypothesis is that osteopathic manual medicine will significantly improve the range of motion, motor function, and quality of life of subjects with primary cervical dystonia.
