Behavioral Intervention for Lifestyle Physical Activity in Parkinson's Disease (LifePD)

The investigators propose a Stage-I randomized controlled trial (RCT) of a remotely-delivered, 16-week social-cognitive theory-based behavioral intervention focusing on combined exercise (aerobic and resistance) training for yielding increases in device-measured physical activity and improvements in cognitive function, symptoms, and quality of life (QOL), and social-cognitive theory (SCT) outcomes among physically inactive persons with Parkinson's disease (PD). Participants (N=50) will be randomly assigned into exercise training (combined aerobic and resistance exercise) condition or active control (flexibility and stretching) condition. The 16-week intervention will be delivered and monitored remotely within a participant's home/community and supported by Zoom-based chats guided by SCT via a behavioral coach. Participants will receive training materials (e.g., prescriptive manual and exercise equipment), one-on-one coaching, action-planning via calendars, self-monitoring via logs, and SCT-based newsletters. The investigators hypothesize that the home-based exercise intervention will yield improvements in cognitive, symptomatic, and QOL outcomes.

Detailed Description

Parkinson's disease (PD) is a neurodegenerative disorder of the dopamine-producing nerve cells in the basal ganglia, and age is a primary risk factor for PD. Cognitive impairment is prevalent, disabling, and poorly managed among the 1 million adults living with PD in the United States. Indeed, cognitive impairment begins early in PD, and dementia develops in 80% of persons with PD. Cognitive impairment is further associated with worse fatigue, depression, anxiety, pain, and quality of life (QOL) in PD. Those observations underscore the importance of identifying efficacious approaches for managing cognitive impairment and its consequences, and promoting additional health benefits among those with PD. To date, researchers have examined the benefits of supervised, structured exercise training for managing outcomes of PD, but this approach has clear barriers associated with travel, transportation, and participation (i.e., loss of driving ability, social isolation, and lack of community integration) that are common in PD. The investigators believe that there is merit in the promotion of physical activity for managing cognitive dysfunction and other symptom and QOL outcomes in PD. The investigators offer a novel and innovative approach for promotion of physical activity in PD based on their extensive experiences from Phase I, II, and III randomized controlled trials (RCTs). Those RCTs indicate that the remotely-delivered, social-cognitive theory-based behavioral intervention has successfully increased self-reported and device-measured physical activity in persons with multiple sclerosis (MS). This approach has further resulted in improvements in cognition and walking outcomes, symptoms of fatigue, depression, anxiety, and pain, and QOL among persons with MS. The investigators leverage their experiences and preliminary results in MS, and propose a Stage-I RCT that examines the feasibility and efficacy of a remotely-delivered, theory-based behavioral intervention focusing on combined exercise (aerobic and resistance) training for yielding immediate improvements in device-measured physical activity (primary outcome) among persons with PD who are physically inactive. The investigators further examine the efficacy of this behavioral intervention for improvements in cognitive function, symptoms, and QOL (secondary outcomes). The proposed study, if successful, will provide experiences and pilot data necessary for the design of a subsequent Stage-II RCT that examines the efficacy of the behavioral intervention for immediate and sustained improvements of outcomes in an appropriately-powered and clearly-demarcated sample of adults with PD (i.e., those 50+ years of age who are prescreened for cognitive impairment). This line of research may yield "real-world" guidelines for physical activity that can be implemented for the treatment of cognitive dysfunction and other outcomes in PD. Such an opportunity for rehabilitation of cognitive function using an approach with broad reach and scalability is paramount considering the prevalent, disabling, and poorly managed nature of cognitive impairment in PD and limited efficacious resources for its treatment.

Description

Inclusion Criteria:

• confirmed diagnosis of PD
• Internet and email access

• self-reported ability to ambulate without assistance
• age of 50+ years
• English as a primary language

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: GET Up PD; Remotely-coached/guided, home-based program delivered using telerehabilitation focusing on aerobic fitness and muscle strength as a mode of training	Behavioral: GET Up PD; The exercise training prescription involves performing 3 days per week and include (a) aerobic exercise: 30+ minutes of moderate-intensity walking (≥100 steps/min) monitored by a waist-worn pedometer, and (b) resistance training: 1-3 sets, 8-12 repetitions of 5-10 exercises targeting lower and upper body, and core muscle groups using elastic bands.; Other components of the GET Up PD program include appropriate exercise equipment (pedometer, resistance bands), one-on-one coaching sessions via Zoom, action-planning via calendars, logbooks for self-monitoring, and SCT-based newsletters.
Active Comparator: Stretching and Flexibility; Remotely-coached/guided, home-based program delivered using telerehabilitation focusing on stretching and range of motion as the mode of training	Behavioral: Stretching and Flexibility; The training will involve the same frequency, duration, timeline, behavior change content, and interactions with behavioral coach as the GET Up PD program, and account for activity, social-contact, and attention.; Other components of the Stretching and Flexibility program include appropriate exercise equipment (yoga mat), one-on-one coaching sessions via Zoom, calendars, logbooks and newsletters similar to the GET Up PD program.
