Outline

Text

Objective: Direct electrical stimulation of the peroneal nerve, using the implantable peroneal nerve stimulator, enables a therapy of the centrally caused drop foot, improving the gait of the patients. In this paper, we present long-term results at 36-month follow-up post implantation.

Methods: A total of 33 patients, 27 stroke and 6 multiple sclerosis (MS) patients, suffering from spastic drop foot were implanted in our center and assessed in terms of gait endurance, speed, risk of fall and life quality at baseline and 36 months following implantation.

Results: The six min gait endurance test increased from 202±41 m to 380±30 m in 81% while using the implant. Gait speed measured over 20 m increased in average in 41.8 %, the time needed decreased from 31.8±10.2 s without to 18.5±4.6 s by using the implantable peroneal nerve stimulator. Gait steadiness improved, measured by the Timed Up and Go (TUG) test in 36.6%. Thirty-one of 33 patients reported remarkable improvements of their quality of life following direct electrical nerve stimulation.

Conclusion: These findings confirm previously published efficacy data at 12 month after implantation and underline the long-lasting effect of the implant.
