Feasibility and Acceptability of a Physical Activity Behavior Change Intervention for Parkinson's Disease

The investigators will recruit 14 individuals with early stage Parkinson's disease (Hoehn and
Yahr stage I & II). The investigators will conduct a single arm cohort. (pre and post
intervention) pilot feasibility study over 4 months with embedded process analyses of
Preactive-HD, a physical activity coaching intervention program. Previous studies conducted
by the investigators will be utilized to adapt the Engage-HD physical activity coaching
program to people with early stage PD. The intervention will include a participant/coach
interaction and disease-specific workbook grounded within the framework of self-determination
theory. The coaching sessions will be conducted by an occupational therapist and will entail
six coaching sessions (either face-to-face or remote video sessions via secure Webex
connection via computer or smart phone, or phone call if internet/smart phone is not
available to participant). The first session (approximately 45 min) will lay the groundwork
for the program, and the remaining sessions will serve to provide directed support in
relation to regular physical activity and exercise. Participants will develop physical
activity goals and will be supported with individual physical activity progression.
Participants will be given Fitbit devices as a motivational tool and to track activity
progression.
