EMG guided Training & Testing in Rehabilitation for Patients after TMR
Targeted Muscle Reinnervation (TMR) provides an opportunity to improve prosthesis control for patients with high amputations (transhumeral or glenohumeral). During surgery, nerves of the arm are re-routed to muscles of the residual limb or chest, thus yielding additional myo-signals that can be used to control a prosthesis more intuitively.
After the TMR surgery has been performed and the nerves have healed, the patients undergo a structured rehabilitation program, which we call “TechNeuroRehabilitation”. The process takes about 1.5 years, depending on the level of amputation. During this time, the patient learns how to control their new neuro-muscular interface.
This rehabilitation process can be divided into 3 stages:
- Re-innervation i.e. the surgery followed by wound healing;
- Signal training: where the patient has to learn control and separation of signals
- Prosthetic fitting after the patient can reliably control sufficient signals. In this process stage 2 requires maximum therapeutic effort and is highly cognitive. After finishing stage 3, the patient should be capable of using the prosthesis in daily life.
