Objective: To establish the effects of a twelve week, community based, group exercise intervention for people moderately affected with Multiple Sclerosis (MS) (Extended Disability Status Score 5-6.5).
Design: Randomised controlled pilot trialSetting: Two community leisure centres.Participants: 32 subjects with MS were randomised into an intervention or control group.
Intervention:The intervention group received twelve weeks of twice weekly, 60 minute group exercise sessions, which included mobility, balance and resistance exercises. The control group received usual care.
Main Outcome measures:An assessor blinded to group allocation assessed participants at baseline, after eight weeks and after twelve weeks (i.e after the intervention period). The primary outcome measure was 25 Foot Walk time (T25FW), secondary outcomes assessed walking endurance, balance, physical function, leg strength, body mass index, activity levels, fatigue, anxiety and depression, quality of life and goal attainment.
ResultsThe intervention led to an improvement in all outcome measures. Physical activity results showed a significant group effect (p<0.001) and interaction effect (p=0.009), post hoc analysis revealed this was significant at week eight (p<0.001) and week twelve (p=0.005).Balance confidence results showed a significant group effect (p=0.001). Good effect sizes were found for activity levels (d=1.05), dynamic balance (d=0.80), perceived balance (d=0.94) and leg strength (d=1.33).
Conclusion:Although further research is required, the results of the study suggest that community based group exercise classes are a feasible option for people moderately affected with MS, and offer benefits such as improved physical activity levels, balance and leg strength.3
