Web-based physiotherapy for people affected by multiple sclerosis: a single blind, randomized controlled feasibility study.

Abstract

OBJECTIVE:: To examine the feasibility of a trial to evaluate web-based physiotherapy compared to a standard home exercise programme in people with multiple sclerosis. DESIGN:: Multi-centre, randomized controlled, feasibility study. SETTING:: Three multiple sclerosis out-patient centres. PARTICIPANTS:: A total of 90 people with multiple sclerosis (Expanded Disability Status Scale 4-6.5). INTERVENTIONS:: Participants were randomized to a six-month individualized, home exercise programme delivered via web-based physiotherapy ( n = 45; intervention) or a sheet of exercises ( n = 45; active comparator). OUTCOME MEASURES:: Outcome measures (0, three, six and nine months) included adherence, two-minute walk test, 25 foot walk, Berg Balance Scale, physical activity and healthcare resource use. Interviews were undertaken with 24 participants and 3 physiotherapists. RESULTS:: Almost 25% of people approached agreed to take part. No intervention-related adverse events were recorded. Adherence was 40%-63% and 53%-71% in the intervention and comparator groups. There was no difference in the two-minute walk test between groups at baseline (Intervention-80.4(33.91)m, Comparator-70.6(31.20)m) and no change over time (at six-month Intervention-81.6(32.75)m, Comparator-74.8(36.16)m. There were no significant changes over time in other outcome measures except the EuroQol-5 Dimension at six months which decreased in the active comparator group. For a difference of 8(17.4)m in two-minute walk test between groups, 76 participants/group would be required (80% power, P > 0.05) for a future randomized controlled trial. CONCLUSION:: No changes were found in the majority of outcome measures over time. This study was acceptable and feasible by participants and physiotherapists. An adequately powered study needs 160 participants.
