Somatosensory Perception Following Lower Limb Amputation Clinical Trial
Official title:
Evaluate Tactile Sensation and Proprioception in Lower Limb Amputees Using Neuromodulation
The purpose of this study is to investigate how leg amputee patients can feel sensations with neuromodulation while they are using a prosthetic leg. "Neuromodulation" is the process by which the nervous system can be regulated by targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body. In this study, the investigators plan to use either electrical stimulation of the spinal cord (Spinal Cord Stimulation) or electrical stimulation of the dorsal root ganglion (DRG stimulation) as methods for neuromodulation. Participation in this study will involve visiting the K-Lab (Human Performance Laboratory) at Duke's Sports Medicine Institute once prior to trial implant surgery, if feasible, and four times during the two weeks following the implantation of trial stimulation leads to evaluate sensations related to touch and position of the prosthetic leg as they are generated by neuromodulation.
