Accessible exercise equipment and individuals with multiple sclerosis: Aerobic demands and preferences

BACKGROUND: Although exercise training has benefits for individuals with multiple sclerosis (MS), research regarding the type of exercise equipment that requires the greatest aerobic demand, and consumer-based preferences, is lacking. OBJECTIVE: To determine the aerobic demands of various pieces of accessible exercise equipment and consumer-based preferences on several domains. METHODS: Ten individuals with moderate-severity MS had their VO2 measured during 10 minutes of moderate-intensity arm ergometry (AE), body-weight support treadmill training (BWSTT), recumbent arm-leg exercise (NuStep), FES-arm exercise (RT300), FES-leg exercise (RT300) and FES arm-leg exercise (RT200). VO2peak test was also measured on the NuStep and the RT200. Equipment preferences were determined by questionnaire after moderate exercise sessions. RESULTS: AE required a lower VO2 compared to the NuStep (p = 0 .02), and FES-arm exercise required a lower VO2 compared to the NuStep (p = 0.01) and FES arm-leg exercise (p = 0.04). There was no difference in VO2peak when using the NuStep or FES armleg exercise. AE was perceived as safer than BWSTT, but otherwise there were no preferences for any equipment. CONCLUSIONS: For individuals with moderate-severity MS, arm-only exercise requires less aerobic demands than combined arm-leg exercise at a moderate intensity. Perceived risks may be greater when exercise requires a transfer, upright positioning, or assistance.
