Muscle-Based Control Of Advanced Upper-Limb Prostheses
The goal of this study is to record muscle activity while a person performs a variety of hand and arm movements in order to help develop advanced prosthetic limbs.
Research Eligibility:
- Do you have an arm amputation?
- Are you at least 1 year post amputation?
- Are you between the ages of 18 and 70?
Spinal Cord Stimulation for Sensory Restoration and Phantom Limb Pain Reduction after Upper-Limb Amputation
The goal of this study is to understand the types of sensations produced by electrical stimulation of a person’s spinal cord and spinal roots, as well as the effects of stimulation on phantom limb pain and ability to control a prosthetic limb.
Research Eligibility:
- Do you have an arm amputation?
- Are you at least 1 year post amputation?
- Are you between the ages of 18 and 70?
Spinal Cord Stimulation for Restoration of Function after Lower-Limb Amputation
The goal of this study is to understand the types of sensations produced by electrical stimulation of a person’s spinal cord and spinal roots, as well as the effects of stimulation on phantom limb pain and ability to control a lower-limb prosthesis.
Research Eligibility:
- Do you have a leg amputation?
- Are you at least 1 year post amputation?
- Are you between the ages of 18 and 70?
Evaluation of an Implantable Intramuscular Device to Control a Myoelectric Prosthesis
Study participants will learn to control a myoelectric prosthesis using muscle activity recorded from electrodes implanted in the muscles of the residual limb. The data collected will support our hypothesis that EMG signals can be recorded and transmitted wirelessly in order to provide control of prosthetic hand and wrist functions.
Eligibility:
- Amputation of one hand/arm below elbow
- More than 1 year after amputation
- Ages 22-70
- No serious disease that would affect participation
- There are additional criteria to meet for inclusion.
