Wheelchair-modified ergometer rowing exercise in individuals with spinal cord injury: a feasibility, acceptability, and preliminary efficacy study.

ABSTRACT:

Study design

Exploratory clinical investigation.

Objectives

To assess the feasibility, acceptability, and preliminary efficacy of upper-body rowing exercise adapted to wheelchair users with spinal cord injury (SCI).

Setting

University exercise laboratory.

Methods

Eight individuals with SCI exercised on a rowing ergometer modified for wheelchair users (REMW), three times weekly, for up to 30 min per session. Participants completed feasibility and acceptability questionnaire (1-5 Likert scale), and the Wheelchair Users Shoulder Pain Index (WUSPI) before and after six weeks of exercise. Average power output (PO_AVG), distance rowed, percent peak heart rate (%HR_peak), and rating of perceived exertion (RPE) (6-20 scale) were monitored throughout the 18 exercise sessions and analyzed to evaluate preliminary efficacy of the exercise modality.

Results

All eight participants completed the study (97% adherence). Participants rated the exercise high on the feasibility and acceptability scale; median (interquartile range) = 5.0 (4.0-5.0), where higher numbers indicated greater feasibility. Shoulder pain was reduced by 21% yet not significantly different from baseline (p = 0.899). Physiological measures (%HR_peak = 80-83%; RPE = 15.0-16.0) indicated a high cardiovascular training load. From week 1 to week 6, PO_AVG and distance rowed increased by 37 and 36%, respectively (both p ≤ 0.001).

Conclusions

Data from six weeks of exercise on the REMW suggests that upper-body rowing is a feasible and acceptable exercise modality for wheelchair users with SCI. Session data on %HR_peak, RPE, and shoulder pain indicate that REMW evoked moderate to vigorous intensity exercise without exacerbation of shoulder pain. Future research is required to quantify potential training-induced changes in cardiorespiratory fitness.

Project description:IntroductionCardiovascular and metabolic diseases are a growing concern for individuals with spinal cord injury (SCI). Physical inactivity contributes to cardiometabolic morbidity and mortality in the SCI population. However, previous studies have shown mixed results regarding the effects of exercise on cardiometabolic risk factors in individuals with SCI. This discrepancy could be influenced by insufficient exercise stimuli. Recent guidelines recommend 30 min of moderate-to-vigorous intensity aerobic exercise, three times per week, for improvement in cardiometabolic health in individuals with SCI. However, to date, no studies have implemented an exercise intervention matching the new recommendations to examine the effects on cardiometabolic risk factors. Therefore, the primary objective of this study is to determine the effects of 12 weeks of wheelchair user-modified upper-body rowing exercise on both traditional (constituents of the metabolic syndrome) and novel (eg, vascular structure and function) cardiometabolic risk factors in manual wheelchair users with SCI.Methods and analysisA randomised controlled trial will compare 12 weeks of upper-body rowing exercise, 30 min three times per week, with a control group continuing their normal lifestyle. Outcome measurements will be performed immediately before (baseline), after 6 weeks (halfway), 12 weeks of training (post) and 6 months after the termination of the intervention period (follow-up). Outcomes will include inflammatory (eg, C reactive protein) and metabolic biomarkers determined from venous blood (with serum fasting insulin as primary outcome), body composition, arterial blood pressure, cardiorespiratory fitness level, brachial artery vascular structure and function and autonomic nervous system function.Ethics and disseminationThis trial is reported to the Danish Data Protection Agency (J.nr. 2019-899/10-0406) and approved by the Committees on Health Research Ethics in The North Denmark Region on 12 December 2019 (J.nr. N-20190053). The principal investigator will collect written informed consent from all participants prior to inclusion. Irrespective of study outcomes, the results will be submitted to peer-reviewed scientific journals for publication.Trial registration numberNCT04390087.

Project description:AimThe aim was to assess safety and feasibility of Hybrid High-Intensity Interval Training (HIIT) using Functional Electrical Stimulation (FES) leg cycling and arm ski ergometer in people with Spinal Cord Injuries (SCI).MethodEight outpatients (mean age 42.8 years; 7 men) with stable SCI paraplegia (mean 14.5 years since injury) participated in hybrid HIIT (90% peak watts; 4 × 4-min intervals), three times a week (over 8 weeks). Primary outcomes were Adverse Events (AE), participant acceptability, shoulder pain, training intensity (% peak watts), and attendance. Secondary outcomes were effect on peak oxygen uptake (VO2peak) during FES hybrid poling, mean watts, self-reported leisure time physical activity, quality of life, and fatigue.ResultsNo serious AE occurred; acceptability with the training modality was high, while shoulder pain increased by 9% (SD 95.2). During training, 50% of the participants reached > 90% peak watts during the intervals, three with the legs (FES cycle) and one with the arms (Ski-Erg). Overall, mean training intensity (% peak watts) was 92% (SD 18.9) for legs and 82% (SD 10.3) for arms. Proportion of fulfilled training minutes was 82% (range 36-100%); one participant dropped out after 6 weeks due to back pain. Mean VO2peak increased by 17% (SD 17.5). Participants reported increased leisure time physical activity and health-related quality of life, besides reduced fatigue.ConclusionHybrid HIIT was safe for people with SCI paraplegia. The majority of the criteria for feasibility were met with acceptable attendance rate, limited drop out, participants enjoyed training, and increased VO2peak and mean watts. However, the intensity of 90% peak watts was reached by < 60% of the participants despite high RPE ratings during training. The method of measuring and calculating intensity needs to be studied further before a study using this HIIT protocol is undertaken.Trial registrationClinicaltrials.gov , NCT04211311 , registered 12 December 2019 retrospectively registered.
