Brief Summary

This study seeks to examine the reach and maintenance of an in-home cycling program for underserved individuals with Parkinson disease and to determine the effectiveness of a 6-month in-home, progressive, tele-exercise cycling program and 3-month health coach follow-up for those same participants.

Detailed Description

The benefits of exercise for individuals with Parkinson disease (PD) have been well documented; however, individuals with PD living in rural and underserved urban settings are largely unable or unwilling to participate in group exercise programs due in large part to their distance from such programs and financial considerations. Additionally, community based programs which provide social support and engagement have been shown to benefit elderly individuals as well as individuals with pathology, but are equally unattainable to this group. Taking the exercise to these individuals via telemedicine or tele-exercise may be an ideal means of delivering this type of intervention.

The long-term goal of this project is to improve outcomes for underserved populations of individuals with Parkinson disease (PD) by providing access to in-home physical activity via a telehealth approach. Approximately one million Americans currently live with a diagnosis of PD and it has been estimated that delaying the progression by 20% would result in a $75,891 savings per individual based on reduced health care costs, income maintenance, increased duration of life and improved quality of life. However, individuals with PD of lower socioeconomic status, people of color and rural dwelling seniors have been critically underserved by clinical and academic programming resulting in poorer health outcomes.

This study examines 1) the Reach, Effectiveness, Implementation and Maintenance and 2) the optimal delivery method for an in-home exercise intervention program for individuals with PD living in underserved communities. A managed and meaningful exercise intervention will be delivered that not only addresses the benefits of physical activity for individuals with PD, but also offers a social connection to research staff outside of the participant's typical caregiver(s).

SPECIFIC AIM 1: Examine the reach and maintenance of an in-home cycling program for underserved individuals with PD. Reach will be assessed by examining the demographic characteristics of the individuals enrolled and through the administration of a questionnaire on objective and subjective socioeconomic status to better understand their level of accessibility to services, perceived barriers and economic status. The investigators will also explore the implementation of a health coach to promote effective maintenance of the program after the 6-month intervention. Finally, two interviews will be conducted to better understand strengths and weakness of the program and to better address the needs of the participants in future studies.

* Hypothesis 1a: Demographic characteristics including race and socioeconomic status of the enrolled participants will not statistically differ from the characteristics of the state of WI.

* Hypothesis 1b: Feedback from participant interviews will inform future delivery of the in-home cycling program.

SPECIFIC AIM 2: Determine the effectiveness of a 6-month in-home, progressive, tele-exercise cycling program and 3-month health coach follow-up for underserved populations of individuals with PD.

* Hypothesis 2a: Participants will improve performance of activities of daily living from baseline to posttest. These effects will be maintained at 3-month follow-up.

* Hypothesis 2b: Participants will significantly improve measures of gait and balance performance and non- significantly improve fall rate from baseline to posttest. These effects will be maintained at 3-month follow-up in the group piloting implementation of a health coach, but not in solo follow-up group. Falls data will allow for effect size calculations for future applications.

* Hypothesis 2c: Activity level as measured by an activity monitor will increase from baseline to posttest. This effect will be maintained at 3-month follow-up in health coach group, but not in the solo group.

Study Design: 40 qualified individuals will be paired based on disease severity (score on subsection III of the UPDRS) and age and randomly assigned to either the cycling group or the normal care control group for 6 months. For those in the cycling group, participants will interact via Skype with study team members during all cycling sessions. This intervention will allow the individuals enrolled to participate in regular exercise and a community activity that promotes social support and engagement. The proposed pilot maintenance model for the 3-month period following the intervention will implement a health coach model with scheduled sessions every other week to discuss goals and motivation while decreasing the total contact time with the participant. Individuals in the normal care control group will crossover and complete the cycling intervention following the initial 6 months.

Social Cycling GroupSocial Cycling GroupExercise bike delivered to their home, custom fit to their needs and installed in a safe location, sessions will consist of up to 30 minutes of cycling while engaged in social interaction with a research staff member, thus providing a social/community aspect that would not otherwise be present.
Biweekly health coachcoaching callsFollowing completion of the 6-month cycling intervention, participants will receive a call every 2-weeks to discuss ongoing maintenance efforts.
No health coachNo coaching callsFollowing the conclusion of the 6-month cycling session, participants will be contacted monthly to record falls. No discussion of ongoing exercise will occur
Primary Outcome Measures
NameTimeMethod
Change in Canadian Occupational Performance Measure (COPM) scoresbaseline, post-test (~6-months), 3-month follow up (~9-months)

The Canadian Occupational Performance Measure (COPM) will be administered to assess the participant's self-report of performance and satisfaction on a scale of 1 to 10 on self-selected occupational tasks. Performance and satisfaction scores range from 1 (lowest) to 10 (highest) for each identified item. The averages for each of the top three occupational tasks will be reported.

Secondary Outcome Measures
NameTimeMethod
Change in Pittsburgh Sleep Quality Indexbaseline, post-test (~6-months), 3-month follow up (~9-months)

The Pittsburgh Sleep Quality Index measures participant quality of sleep in each of 7 domains over the last month: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. The total possible range of scores is 0-21 with 0 indicating no difficulties and 21 indicating severe difficulties.

Change in Timed Up and Go Testbaseline, post-test (~6-months), 3-month follow up (~9-months)

The Timed Up and Go Test measures the amount of time (in seconds) that it takes for the participant to stand, walk 3 meters away, and return to the seated position.

Change in Four Square Step Testbaseline, post-test (~6-months), 3-month follow up (~9-months)

The Four Square Step Test measures the amount of time it takes to step forward, sideways, backward, sideways (and then in the reverse direction back to the start) through the quadrants of a square, stepping over canes that defines its boundaries.

Change in Fall Frequencybaseline, post-test (~6-months), 3-month follow up (~9-months)

The Fall History Questionnaire is a 6-item survey that asks about Fall rate in the last 2 weeks, last month, last 6 months, the typical cause of a fall, and how the fear of falling may influence daily activities. The hypothesis is that Fall frequency will be improved in the socially engaged cycling group and not with those cycling alone.

Change in Standardized Gait Analysis: Gait Velocitybaseline, post-test (~6-months), 3-month follow up (~9-months)

A portable electronic walkway, embedded with sensors, will be used to measure spatiotemporal variables including normalized gait velocity. Participants will begin at a starting point two meters from the mat, then walk toward and step onto the mat to continue walking until they achieve the stop line located two meters off of the opposite side of the mat. Data will be collected for forward preferred speed, backward preferred speed, forward fast, tandem and dual task gait. Each participant will complete five trials for each condition or a minimum of 40 steps

Change in Functional Gait Analysis: Gait Velocitybaseline, post-test (~6-months), 3-month follow up (~9-months)

A portable electronic walkway, embedded with sensors, will be used to measure normalized gait velocity while participants complete a functional shopping task on the instrumented surface.

Change in mini-BESTest Scorebaseline, post-test (~6-months), 3-month follow up (~9-months)

The mini-BESTest will be used to assess balance. This 14-item, clinical battery is used to assess balance in four component areas (anticipatory transitions, postural response, sensory orientation and dynamic gait) and provides a single number summary of balance performance. Scores range from 0 to 28 with higher scores indicate higher function.

Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UPDRS)baseline, post-test (~6-months), 3-month follow up (~9-months)

Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UPDRS) assesses disease progress and clinical symptom presentation in four parts: I - Non-motor experience of daily living; II - Motor experience of daily living; III - Motor; and IV Motor complications. Scores range from 0 to 199, with 199 indicating most severe.
