- Brief summaryDropped foot is a condition found in several patient groups, including Multiple Sclerose, incomplete spinal cord injury and most notably, stroke.
Stroke is one of the most common disorders affecting the neuromuscular system.
The conventional management of dropped foot has been to use a rigid orthosis to maintain the ankle in a neutral position. This has major limitations as a treatment, being both uncomfortable and awkward to use and hence is often rejected by patients and therapists.
Currently, FES systems for the treatment of dropped foot are in clinical use in significant numbers.
Functional Electrical Stimulation (FES) is the artificial stimulation of muscles with the purpose of evoking a motor response.
Compared with the use of orthosis electrical stimulation has a number of advantages: it prevents muscle atrophy, the blood flow remains normal or even improves and it is cosmetically better accepted.
An implantable system was developed that stimulates the two branches of the peroneal nerve separately. Results from previous studies indicate that the system is safe to use, well liked by the patients, provides selectivity over moments at the ankle joint and increases both walking speed and endurance.
In the present study the additional value of the implantable stimulator in comparison with the conventional treatment will be examined by measuring different parameters.
