Background: A direct stimulation of the peroneal nerve by ActiGait implantable drop foot stimulator is a potent therapy, which was already described for stroke related drop foot.
Materials and methods: We firstly report the successful application of ActiGait implantable drop foot stimulator in 6 patients with MS. Six patients with a stable MS and a 2-year persisting spastic leg paresis received an implantable ActiGait drop foot stimulator after successful surface test stimulation. Six weeks after operation, the stimulator was activated and the gait was evaluated with a 1 year follow up. Patients’ satisfaction was assessed due to a questionnaire.
Results: In 20 meter gait test and timed up and go test, stimulation with ActiGait significantly reduced the needed time about on average 21.7 % and 46.1 %. The median covered distance of stimulated patients after 6 minutes walking increased significantly from 217 meters to 321 meters, even compared to surface stimulation (264 meters). Patients with an implanted ActiGait stimulator noticed a pronounced improvement of mobility, social participation and quality of life.
Conclusion: The ActiGait implantable drop foot stimulator improved gait speed and endurance and quality of life in all patients. It may serve as a new therapeutic option in patients with MS related drop foot.
