PARKINSON DISEASE (Disorder)
Conditions
Brief summary
Parkinson's disease is a progressive neurodegenerative disorder with no curative treatment currently available. Its symptoms lead to increasing limitations in daily activities, with impairments in manual dexterity being particularly relevant. Handwriting difficulties are common in patients with Parkinson's disease; however, it remains unclear whether a rehabilitation program based on handwriting exercises can improve overall manual dexterity and daily functioning. This randomized, single-blind controlled trial aims to evaluate the effects of a 12-week home-based calligraphic handwriting exercise program on manual dexterity in patients with Parkinson's disease. Participants will be recruited from the Movement Disorders Clinic of Hospital 12 de Octubre (Madrid, Spain) and randomly assigned to either an intervention group or a control group. Manual dexterity will be primarily assessed using the Purdue Pegboard Test across scheduled study visits. Secondary outcomes will include measures of dexterity related to activities of daily living, quality of life, and motor function.
Interventions
BEHAVIORALCalligraphic Handwriting Exercise Program
A structured home-based calligraphic handwriting exercise program designed to train fine motor control and manual dexterity. Participants perform predefined handwriting exercises regularly over a 12-week period using provided written materials.
