Upper Extremity Skills, Trunk Control, and Body Awareness in Parkinson's Disease

Parkinson's disease is associated with impairments in upper extremity function, postural control, and sensory-motor processing that may negatively affect daily activities and quality of life. While upper extremity dysfunction has been extensively investigated, the potential contributions of trunk control and body awareness have received less attention. This cross-sectional observational study aims to compare upper extremity skills, trunk control, and body awareness between individuals with Parkinson's disease and healthy adults, and to examine the relationships among these variables within the Parkinson's disease group. The findings may improve understanding of factors associated with upper extremity performance and support the development of more comprehensive rehabilitation approaches for individuals with Parkinson's disease.
