Designing a screening battery for exercisers with Parkinson's disease

Area of Science:

• Neurology
• Rehabilitation Science
• Exercise Physiology

Background:

• Parkinson's disease (PD) is a progressive neurodegenerative disorder impacting motor function.
• Functional decline in PD necessitates regular monitoring and tailored exercise interventions.
• Existing screening methods often pose barriers for community-based exercise professionals.

Purpose of the Study:

• To develop and validate a brief, easily administered functional screening battery for individuals with Parkinson's disease (PD).
• To create a tool for community exercise professionals to measure functional changes in PD patients.
• To enhance exercise adherence and motivation in individuals with PD through objective feedback.

Main Methods:

• A mixed-methods approach involving interviews with exercise professionals and persons with PD (n=57).
• Development of a screening battery requiring minimal equipment and under 20 minutes to administer.
• Repeated administration of the screening battery over 8-16 weeks with performance analysis using paired t-tests and Cohen's d effect sizes.

Main Results:

• The developed screening battery is time-efficient (<20 min), requires minimal equipment, and is suitable for group or individual settings.
• Persons with PD showed significant functional improvements in sit-to-stand (d=-0.71), 2-minute walk test (d=-3.83), and arm curls (d=-0.78).
• Objective feedback from the screening motivated participants and indicated potential for increased exercise adherence.

Conclusions:

• A brief, functional screening battery can be effectively implemented by community exercise professionals for individuals with PD.
• Objective assessment results serve as a motivator, potentially increasing exercise adherence and slowing functional decline.
• This tool aids in detecting functional deficits and tailoring exercise programs to improve quality of life in people with Parkinson's disease.
