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

Abstract

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). VO_2peak 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 VO_2peak when using the NuStep or FES arm-leg 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.
