Impact on activities of daily living using a functional electrical stimulation device to improve dropped foot in people with multiple sclerosis,measured by the Canadian Occupational Performance Measure

Abstract

Background: Dropped foot is a common problem following multiple sclerosis. Functional electrical stimulation can elicit an active muscle contraction providing dorsiflexion and eversion.

Objective: To determine if the Odstock dropped foot stimulator (ODFS), improved Activities of Daily Living for people with multiple sclerosis.

Method: 64 people with unilateral dropped foot due to secondary progressive multiple sclerosis took part in a randomized controlled trial. Research volunteers were assigned to a group using the ODFS or a group who received physiotherapy exercises for 18 weeks. Outcome measures were the Canadian Occupational Performance Measure (COPM) and a falls diary.

Results: Results of 53 research volunteers are reported. Improvements in performance and satisfaction scores were greater in the ODFS group than the exercise group; (p < 0.05). Use of the ODFS was also perceived as effective in reducing tripping and increasing walking distance. The median number of falls were 5 in the ODFS group and 18 in the exercise group (p = 0.036) over the study period.

Conclusion: The study shows that people with multiple sclerosis using the ODFS increased their COPM performance and satisfaction scores of their identified problems of Activities of Daily Living more than a matched group who received physiotherapy exercises. ODFS users also experienced fewer falls.
