Targeted Muscle Reinnervation, or TMR for short, is a groundbreaking treatment method used after an amputation of the upper arm or shoulder disarticulation. During the surgical procedure, nerves that were previously used to control the missing limbs are reconnected to the muscles of the residual limb, breast or back. During the healing process, the nerves grow back into the new muscles.

Reconnecting the nerves

Reconnecting the nerves with muscles in alternate areas of the body makes it possible for the patient to control the arm prosthesis he or she will be fitted by “thought signal” and thus perform several movements simultaneously.

For the amputee, being fitted with a TMR prosthesis this not only results in a much more intuitively controlled prosthesis but also increases independence in daily life.


In order to get the most of the new prosthesis, the patient will embark on a course of intense coordinative and neuromuscular training. This training commences without the prosthesis and continues once it has been fitted.
