Targeted Muscle Reinnervation
Also written as: TMR — Targeted Muscle Reinnervation
A surgical procedure that redirects residual limb nerves to nearby muscles, creating additional electromyographic signals for improved prosthetic control.
Full Definition
Targeted muscle reinnervation (TMR) is a surgical technique in which residual peripheral nerves are transferred to reinnervate nearby denervated muscles, producing new surface electromyography (EMG) sites that can be used to control advanced myoelectric prostheses. TMR also serves to reduce neuroma formation and phantom limb pain. Editors working with surgical reports, prosthetic candidacy assessments, or payer appeals letters must spell out the term in full on first mention, then use 'TMR' consistently thereafter. It is distinct from pattern recognition control, which is a software-level approach to interpreting EMG signals; however, TMR often enables pattern recognition by generating richer signal sets.
Usage
Usage note: Abbreviate as TMR after first use; ensure the full term is defined in patient-facing documents where it first appears.
