Targeted Muscle Reinnervation (TMR) for Lower Extremities
TMR is a new surgical procedure that reassigns nerves that once controlled the legs and the foot. By reassigning existing nerves, doctors have improved pain symptoms for patients after amputation. In addition, new research continues to explore the use of TMR for better control of lower extremity amputations, similar to how TMR is used for prosthetic control for upper extremity amputations. TMR can make it possible for people who have had upper extremity amputations to control their prosthetic devices by merely thinking about the action they want to perform. Once experimental, this innovative procedure is now available at The Johns Hopkins Hospital.
What To Expect
Those interested in the procedure to better control their prosthetic leg must undergo a medical review to determine their eligibility. In general, patients must meet the following criteria:
- Amputation at the hip, thigh, or leg
- Willing to participate in rehabilitation
- Those who were born without part or all of their leg and those who have nerve damage, degeneration or paralysis may not be candidates for this procedure.
