Evaluating the Effects of Bimanual Activities with and Without Motivational Strategies on Participation and Upper Extremity Function in Subjects with Parkinson's Disease: Study Protocol for a Randomized Controlled Trial

Abstract

Background: Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor and non-motor symptoms that can impact daily activities. Objectives: Activity-based interventions, particularly when combined with motivational strategies, may enhance upper extremity function and participation in people with PD. Methods: This study will include forty-five patients with PD aged 35 to 85 years, categorized as stages I to III according to the Hoehn and Yahr Scale. Patients will be recruited from neurological and rehabilitation centers and randomly assigned to one of three intervention groups: Activity-based interventions with motivational strategy, activity-based interventions without motivational strategy, and conventional interventions. All participants will undergo a 24-session intervention, three times a week. The study will assess various outcomes at multiple time points, including baseline, session 10, session 18, post-intervention (week 9), and follow-up (week 17). Primary outcome measures will focus on motor control of the upper extremity and participation, while secondary outcome measures will include cognitive function and quality of life. Results: This proposed randomized controlled trial (RCT) aims to investigate the potential beneficial effects of activity-based interventions, combined with motivational strategies, on upper extremity function and participation in activities of daily living (ADLs) for individuals with PD. Conclusions: The expected outcome of this study is to provide valuable insights that can assist occupational therapists in making informed decisions regarding intervention plans for people with PD.
