Abstract
Parkinson's disease (PD) is a progressive neurological disorder with cardinal motor features of tremor, bradykinesia, muscle rigidity, impaired gait and posture. Muscular pain or arthralgia is a common non-motor symptom in PD. The PD-related pain is probably attributed to a combination of altered posture, abnormal muscle tone, and truncal dystonia. A 59-year-old male taxi-driver with PD treated with levodopa for 18 months complained of progressive low back pain and gait difficulties that prevented him from normal activities in the past 2 months. Magnetic resonance imaging showed degenerative disc disease with multiple levels of bulging discs in the lumbar spine. After 35 chiropractic sessions, there was a significant improvement in various aspects of well-being, including pain resolution measured by a numeric rating scale, physical and mental improvement measured by the Parkinson's Disease Questionnaire, gait stability depicted by gait cyclogram, and better postural alignment and stability assessed by radiographic parameters. The current study may serve as an example of spinal manipulation showing the potential to address gait and posture problems associated with pain in a patient with PD. Aging changes in the muscles, bones and joints may accompany PD. Although PD itself is an incurable neurodegenerative disease, functional capacity of the musculoskeletal system can be enhanced by different types of manual therapy, by means of improving muscle strength, joint mobility, and postural balance. The actual duration in sustaining improved outcomes following a course of manipulative intervention remains to be determined.
