Objective To examine the effect of Functional Electrical Stimulation (FES) for dropped foot and hip instability in combination with physiotherapy core stability exercises. Methods Twenty-eight people with secondary progressive multiple sclerosis and unilateral dropped foot participated in a randomized crossover trial. Group1 received FES for correction of dropped foot for six weeks with the addition of hip extension for a further six weeks. In weeks 12-18, FES was continued with the addition of eight sessions of core stability physiotherapy with home-based exercise. FES and home-based exercise were continued until weeks 19-24. Group 2 received the same physiotherapy intervention over the first 12 weeks, adding FES in the second 12 weeks. Results FES improved walking speed and Rivermead Observational Gait Analysis (ROGA) score, whereas physiotherapy did not. Adding gluteal stimulation further improved ROGA score. Both interventions reduced falls, but adding FES to physiotherapy reduced them further. FES had greater impact on Multiple Sclerosis Impact Scale, MSIS-29. Conclusion The intervention was feasible. FES for dropped foot may improve mobility and quality of life and may reduce falls. Adding gluteal stimulation further improved gait quality. Adding physiotherapy may have enhanced the effect of FES, but FES had the dominant effect. © 2013 International Neuromodulation Society.
