High Intensity Functional Training for Individuals With Neurologic Diagnoses and Their Care Partners

The percentage of intervention sessions attended by participants.

Lower extremity strength will be measured via functional test (Five Times Sit to Stand). This test records the amount of time taken to rise and sit to and from a chair five consecutive times. Faster times indicate greater lower extremity strength.

The PDQ-39 is a 39-item participant-reported questionnaire which assesses health-related quality of life across 8 domains (mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, bodily discomfort). Participants respond to each item using a 5-point Likert scale from 0 (never) to 4 (always). Items in each domain are scored by expressing summed item scores as a percentage (ranging from 0 to 100%). Lower scores indicate better quality of life.

Fast-paced walking speed will be measured via 10 meter walk test, which has individuals walk 10 meters with the middle 6 meters timed; two trials are performed and the average time is taken. Faster walking speeds indicate greater mobility with walking.

Fast-paced propulsion speed will be measured via wheelchair propulsion test, which has individuals propel 10 meters and are timed; two trials are performed and the average time is taken. Faster propulsion speeds indicate greater mobility with wheelchair propulsion.

The 6 Minute Walk Test measures a participants ability to cover as much distance (measured in meters) as possible while walking for 6 minutes. Participants will walk along a pre-defined pathway for 6 minutes, resting as needed. The test is a measure of walking endurance with further distances indicating greater endurance.

The 6 Minute Propulsion Test measures a participants ability to cover as much distance (measured in meters) as possible while propelling a wheelchair for 6 minutes. The test is a measure of aerobic endurance with further distances indicating greater endurance.

The MDS-UPDRS measures disability as a result of Parkinson's and allows tracking for progression of the disease. The scale has four parts (1, mentation, behavior and mood, 2, activities of daily living, 3, motor examination, and 4, complications of therapy. Each parkinsonian sign or symptom is ranked on a 5-point Likert scale (ranging from 0 to 4) with higher scores indicating greater impairments. The minimum score on the entire scale is 0 and the maximum is 199.

Physical activity levels will be measured via thigh or wrist-worn accelerometer (activPAL or ActiGraph). These small devices will be worn on the less affected thigh or wrist (or non-dominant thigh or wrist for care partners). Through collecting acceleration data, different intensities of physical activity will be inferred (i.e light, moderate and vigorous intensity physical activity), with moderate-to-vigorous intensity physical activity being used as the primary outcome measure. At all time points, participants will wear the accelerometer for 7 consecutive days.

The number and percentage of participants who remain in the study through the final measurement point at 24 months.

The number of participants recruited will be reported as a percentage of total participants contacted for study participation.

The four square step test measures stepping balance as the time taken to step clockwise and counterclockwise in a square pattern. Faster times indicate greater balance.

The YMCA Bench Press Test measures muscular endurance of the upper body. The test requires participants to complete as many repetitions of barbell bench press as they can with good form. Greater number of repetitions indicates greater muscular endurance.

The 30 second peak power test measures anaerobic power produced (in watts) over 30 seconds on a ski ergometer. Greater wattage indicates greater anaerobic power.

Change will be reported using a visual analogue scale where participants rate their confidence from not confident at all to completely confident.

Change will be reported using a visual analogue scale where participants rate their pain from no pain to worst possible pain.

Change will be reported using a visual analogue scale where participants rate their sleep quality from poor to exceptional.

Change will be reported using a visual analogue scale where participants rate their level of social support from people in the intervention and those outside the intervention. The scale goes from poor to exceptional social support.

Change will be reported using a visual analogue scale where participants rate their level of ability from poor to exceptional on attributes of mobility, power, endurance/stamina, strength and balance.

Using a visual analogue scale, participants rate their feelings of safety with the intervention at 24 months. Scores range from not safe at all to exceptionally safe.

Using a visual analogue scale, participants rate their feelings of satisfaction with coach supervision during the intervention at 24 months. Scores range from not satisfied at all to extremely satisfied.

Using a visual analogue scale, participants rate their feelings of inclusion during the intervention at 24 months. Scores range from minimally included to maximally included.

Using a visual analogue scale, participants rate their feelings of exercise intensity during the intervention at 24 months. Scores range from low intensity to high intensity exercise.

Using a visual analogue scale, participants rate their feelings on exercise variety during the intervention at 24 months. Scores range from low exercise variety to high exercise variety.

Using a visual analogue scale, participants rate their feelings on applicability of exercises to real life during the intervention at 24 months. Scores range from not applicable at all to extremely applicable.
