A pilot study to investigate the effect of aerobic exercise on the mobility and function of people with moderate disability multiple sclerosis (MS). Design: A small group, comparative, pre- and post-intervention study. Setting: A gymnasium within a general hospital. Subjects: Eight subjects, all female, average age 45 years (range 33-61) with moderate disability MS (Kurtzke scale 4-6), were recruited; six completed the study. Intervention: Intervention consisted of bi-weekly sessions of 30 min cycling on a static bike at their maximal level of exertion for 12 weeks. Main measures: The stability of each individual's condition was established pre-intervention using three baseline assessments over two weeks. A battery of tests (the 10-metre and 6-min walk tests, the Functional Reach, the Gulick and the Guys Neurological Disability Scale) were completed pre- and post intervention. Potential negative effects were recorded on the Fatigue Severity Scale and the Modified Ashworth Scale. An independent rater completed assessments post intervention. Inter-rater reliability was found to be acceptable. Results: Comparisons pre- and post intervention (Wilcoxon signed ranked test) showed significant improvement on the Guys Neurological Disability Scale (p = 0.026), with the mean score reducing from 13 to 9, and the 6-min walk test (p = 0.046), with the mean distance increasing from 200 m to 261 m. Other measures failed to reach significance. Conclusions: Findings from this pilot study suggest overall disability and mobility improved with the aerobic training. A positive treatment effect in this small study suggests the need for a larger trial. Knowledge of how to establish predictive heart rate and how to monitor the effects of cycling with-people with MS will be used to inform future clinical trials.
