Brief summary
The goal of this clinical trial are to determine the feasibility and impact of an adaptive rower exercise intervention for adults who use motorized wheelchairs for mobility. The main question\[s\] it aims to answer are: 1. What is the impact on participant's cardiovascular endurance, and perception of mobility and quality of life? 2. Is the intervention feasible, acceptable and safe? examine feasibility of the adaptive rower intervention through measures of acceptability, adherence, intensity and safety for adults who use motorized wheelchairs for mobility. Participants will complete 12 sessions of 10-20 minutes of supervised and coached moderate to vigorous activity using the adaptive rower over a seven week period. Participants will complete pre- and post- outcome assessments of cardiovascular fitness, and outcome surveys,
Detailed description
A rolling prospective clinical trial with a target population of 10 participants in the Columbia, South Carolina area will evaluate the impact of the adaptive rower on cardiovascular fitness, participant perception and feasibility for people who use motorized wheelchairs. Participants will be screened for inclusion/exclusion criteria, perform initial outcome measures and instructions on rowing in the first visit, and then have 12 exercise sessions over 6 or 7 weeks, followed by a final visit for final outcome measures. All research will occur at the University of South Carolina Rehab Lab in the public health research center building. Over the 6-7 week intervention period, participants will exercise approximately two times per week, with two additional visits available in week 7 for any missed sessions to fulfill the 12-visit dosage. Session data will include measures of heart rate, 0-10 Borg rate of perceived exertion (RPE), and power output (rower output in watts). The session goal is to maintain moderate-vigorous intensities (5-8 on the Borg RPE scale) with individually modifiable intervals of work and rest with the goal of 10-20 minutes of moderate-vigorous physical activity total per session depending on the individual's initial fitness levels (as judged by self-reported activity level and performance on the initial six-minute arm test) and progressed as able. After completing the intervention period, participants will return for final evaluation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Six Minute Arm Test | Study Start (Week 1) and at Study Completion (week 7-8) | Submaximal fitness test using an upper body ergometer. Maximum power, maximum rate of perceived exertion and maximum heart rate are recorded. Higher power, lower RPE and lower maximum heart rate is better outcome |
| Spinal Cord Injury Functional Inventory basic mobility, motorized wheelchair mobility and resilience subscales | Study Start (Week 1) and at Study Completion (week 7-8) | Scores from 0-100% where mean scores for population is 50%, higher score better outcome |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| System Usability Scale | Study Completion (week 7-8) | a standardized 10-question survey for perception of usability, scored from 0-100%, higher score, better outcome |
| Physical Activity Enjoyment Scale-Short (PACES-S) | Study Completion (week 7-8) | a standardized 4-question survey for perception of enjoyment of a physical activity intervention, scale is 1 (strongly disagree) to 5 (strongly agree), total score 4-20 with higher score as better outcome |
| Heart Rate (beats per minute), mean and range at rest, mean and range during rowing | 2 x a week through study completion, 7-8 weeks | Heart rate will be recorded at rest and throughout the exercise intervention using a polar heart rate monitor and actigraph. Heart rate near target zone, better outcome |
| Rate of Perceived Exertion (RPE)-Borg 6-20 Scale | 2 x a week through study completion, 7-8 weeks | RPE will be verbally stated by participant and recorded by study personnel at beginning, mid and end of steady state portion, and at each interval for interval exercise. (RPE, 6-20, higher means higher intensity) RPE within target zone of moderate intensity (12-14) better outcome |
| Pain Scale (0-10 visual analog scale) and body location of pain verbalized by participant and recorded by study personnel | 2 x a week through study completion, 7-8 weeks | participant complaints of discomfort or pain verbally stated along with location. Higher means worse pain, lower is better outcome |
