Upper extremity dysfunction is frequently seen in Parkinson's disease. Existing research has shown that bradykinesia, which is main symptom of Parkinson disease, is primarily responsible but the combined effects of spinal posture and axial rigidity on upper extremity functions were not investigated yet. The aim of this study was to investigate upper extremity functions in patients with Parkinson disease and to evaluate relationship of these with spinal posture and axial rigidity.
