Clinical Trial Summary

The overall purpose of this pilot randomized control trial (RCT) is to determine the efficacy of the high-intensity interval training (HIIT) exercise protocols for the WheelMill System (WMS) to improve exercise intensity, cardiovascular fitness, metabolic health, and psychological well-being in manual wheelchair users (MWUs) with spinal cord injury (SCI).

Description:

People with spinal cord injuries (SCI) are at greater health risk for major health conditions and poorer health outcomes than the population without disabilities. For people with SCI, physical activity is critical for both physiological and psychosocial well-being, however 75% of persons with SCI are not active enough to achieve activity-related health benefits. While current exercise guidelines for persons with SCI are limited and vary, health authorities and literature have focused more on recommendations for moderate-intensity exercise, however recent studies have shown that, due to the reduced exercise capacity of the active muscles used in persons with SCI, moderate-intensity exercise alone is inadequate to stimulate meaningful improvements in cardiovascular disease risk. An alternative exercise approach that has demonstrated significant reductions in cardiovascular disease risk and morality is high-intensity interval training (HIIT). Participating in exercise protocols of higher intensity may offer a more effective and time-efficient method of increasing cardiovascular fitness and metabolic health in persons with SCI. However, few studies have evaluated the efficacy of HIIT protocols to increase exercise intensity and clinically improve cardio metabolic health and fitness in this population. The WheelMill System (WMS) is a wheelchair roller-based system that allows persons with SCI to use their personal manual wheelchair for wheelchair training or endurance exercise. With this study, we aim to assess the efficacy of a HIIT intervention conducted on a wheelchair roller-based system in improving cardiorespiratory and metabolic function, psychosocial well-being, and exercise intensity for manual wheelchair users (MWUs) with SCI. We also aim to determine if the roller-based system is a feasible platform for delivering HIIT for MWUs with SCI as well as identifying the perspectives of the participants on the recruitment and enrollment process, the assessment methods, and tolerance and acceptance of the intervention protocol. The long-term goal of this research is to increase cardiorespiratory fitness and reduce cardiovascular and metabolic disease risk in MWUs. This study will serve as the initial step toward that goal by pilot testing a HIIT intervention to increase exercise intensity of MWUs with SCI to promote physiological and psychosocial activity-related health benefits. We will recruit, enroll, and randomize MWUs with SCI into a roller-based Intervention Group (IG) or the Control Group (CG). Participants in the IG will complete an initial exercise education session and a 12-week (3 sessions/wk) evidence-based HIIT program using the roller-based system. Participants in the CG will complete an initial exercise education session and enroll in a 12-week (3 sessions/wk) independent workout program at an accessible community-based fitness facility. This study will measure the potential physiological, functional, and psychosocial health benefits of participating in a HIIT program designed for MWUs with SCI. We will then use the findings to define how exercise training at a higher intensity can support health outcomes and improve therapeutic and community-based interventions to promote cardiorespiratory and metabolic health and well-being of people with SCI.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	VO2peak Change	VO2 peak will be measured using a standard computer-integrated, open-circuit, breath-by-breath metabolic measurement system (TrueOne 2400, Parvo Medics, Sandy, UT, US) while the participant performs a graded-exercise test on an ACE, SCIFIT PRO2 (Life Fitness, Tulsa, OK, US). In addition, an H7 Heart Rate Sensor (Polar Electro Inc., Lake Success, NY, US) will be placed on each participant to monitor heart rate during testing. Each participant will be fitted with a silicone mask to cover his or her mouth and nose while performing the exercise test, which is typically completed in 8-12 minutes depending on the participant's fitness level. The protocol involves a 3-minute warm-up at a workload of 8-10 watts (W) followed by a standard ACE ramp protocol. The ramp protocol requires participants to maintain 60 revolutions per minute (rpm) with incremental increases by 7 W every minute, until exhaustion.	Baseline to Post Intervention at 4 months
Primary	The 6-minute Push Test (6MPT) Change	The 6MPT is a functional mobility and physical fitness test involving manual wheelchair users propelling a designated 30-meter loop. Participants are asked to propel as far as possible on the course within 6 minutes. Total distance propelled is determined by tallying the number of completed 30-meter loops and measuring the partially completed final lap using a tape measure.	Baseline to Post Intervention at 4 months
Secondary	Wong-Baker FACES pain scale (FACES)	FACES is a 10-point visual-analog scale ranging from 0 (no pain) to 10 (worst pain) for participants to rate their level of pain. FACES will be administered at the beginning and end of each session, for all groups, to ensure that sessions (IG, CG) are not causing or exacerbating pain.	At baseline. During each intervention session. At follow up assessment.
Secondary	PROMIS-29 Profile (v2.0) Change	The PROMIS-29 assesses seven different domains: anxiety, depression, fatigue, pain interference, physical function, sleep disturbance, and ability to participate in social roles and activities, as well as a single pain intensity item. The seven domains are scored individually, and the single pain intensity item is reported as its raw score.	Baseline and Post Intervention at 4 months
Secondary	Leisure Time Physical Activity for People with Spinal Cord Injury (LTPAQ-SCI) Change	The LTPAQ-SCI is a self-report measure of leisure time physical activity that assesses minutes of mild, moderate, and heavy intensity activity over the previous seven days.	Baseline and Post Intervention at 4 months
Secondary	Wheelchair User's Shoulder Pain Index (WUSPI) Change	The WUSPI is a self-report measure of shoulder pain in manual wheelchair users (MWUs) during functional activities. The WUSPI consists of a 15-item questionnaire addressing shoulder pain during 15 activities within four domains: transfers, wheelchair mobility, self-care, and general activities. A 10-point visual analog scale ranging from 0 (no pain) to 10 (worst pain) is used to determine pain intensity experienced during each activity. The WUSPI score (from 0 [no pain] to 150 [worst pain] across all items) indicates the participant's level of shoulder pain during functional activities.	Baseline and Post Intervention at 4 months
Secondary	Wheelchair Skills Test Questionnaire (WST-Q) Change	The WST-Q is a self-report measure of wheelchair skills. The WST-Q consists of a 34-item questionnaire addressing a MWU's capacity and performance of wheelchair skills.	Baseline and Post Intervention at 4 months
Secondary	Weight Change	Participants will be weighed during Baseline and Post Intervention assessment. Weight will be reported in kilograms.	Baseline and Post Intervention at 4 months
Secondary	BMI Change	BMI will be reported in kg/m^2	Baseline and Post Intervention at 4 months
Secondary	Body Composition Overall Body Fat % Change	Participants will then undergo body composition assessment via DEXA (General Electric Lunar iDXA), which is commonly used in research due to its precision and safety. Body fat % will be the unit of measure.	Baseline and Post Intervention at 4 months
Secondary	HbA1c Level Change	Blood draws will be completed to measure HbA1c levels in %.	Baseline and Post Intervention at 4 months
Secondary	Cholesterol Change	Blood draws will be completed to measure cholesterol levels. Unit of measure will be in mg/dL.	Baseline and Post Intervention at 4 months
