Feasibility of Telerehabilitation-Monitored Functional Electrical Stimulation on Walking and Quality of Life in People With Multiple Sclerosis: A Case Series.

BACKGROUND

Foot drop in people with multiple sclerosis (MS) commonly leads to decreased mobility and quality of life (QOL). Functional electrical stimulation (FES) of the peroneal nerve can improve the gait of people with foot drop, yet various barriers restrict widespread use. The purpose of this case series was to examine the feasibility of a telerehabilitation-monitored FES device and report changes in functional mobility and QOL in people with moderate MS-related disability.

METHODS

FES use was progressed over 8 weeks via 3 telerehabilitation sessions. Feasibility of telerehabilitation was assessed by percentage of telerehabilitation visits completed and participant-reported satisfaction. At baseline and study completion, functional mobility with and without FES were assessed by the Timed 25-Foot Walk (T25FW), Timed Up and Go (TUG), and 2-Minute Walk Test (2MWT), Multiple Sclerosis Impact Scale (MSIS-29), and the 12-item Multiple Sclerosis Walking Scale (MSWS-12). Fatigue was assessed via the Modified Fatigue Impact Scale (MFIS) before and after the intervention.

RESULTS

Eleven participants (mean age = 50.4 years [SD 10.8]; 2 males) completed the study. All (33/33) telerehabilitation visits were completed and participants attained high levels of satisfaction with no adverse events. At 8 weeks, compared to baseline, there were clinically meaningful improvements on the T25FW, 2MWT, and TUG for 45%, 55%, and 82% of participants, respectively. Clinically meaningful improvements on the MSIS-29 and MSWS-12 were also recorded for 64% and 36% of participants, respectively.

CONCLUSIONS

Telerehabilitation was safe and feasible for FES intervention, and improvements in functional mobility and QOL were observed. Telerehabilitation to monitor FES may improve access and reduce patient burden; therefore, studying its efficacy is warranted.
