Experimentální: BION "twitch" stimulation
The first group will have a stimulation paradigm like that used in a previous feasibility study that preceded the proposed trial, using low-frequency (1-5 PPS) "twitch" stimulation.
|
They will be divided into three groups. Two groups of experimental subjects will receive stimulation using BIONs. The first group will have a stimulation paradigm like that used in a previous feasibility study that preceded the proposed trial, using low-frequency (1-5 PPS) "twitch" stimulation. The second group will have a stimulation paradigm in which tetanic-frequency stimulation (25-50 PPS) is used to produce fused muscle contractions. A third group of experimental subjects will have a standardized program of voluntary exercise. In Groups 1 and 2, the femoral nerve will be stimulated electrically according to the assigned protocol during the 12 week experimental period after implantation of the devices. Individuals assigned to Group 3, receiving conventional exercise therapy for 12 weeks, will be allowed to receive BIONs at the end of the trial, providing they request BION therapy and they have been at least minimally compliant with the exercises. |
