Anterior interosseous nerve conduction study: normative data.
Neurophysiological techniques assessing anterior interosseous nerve (AIN) function and employing surface electrode recordings from the flexor pollicis longus (FPL), have been limited by technical difficulties. The aim of this study was to describe a surface electrode recording technique of investigating the AIN by recording compound muscle action potentials (CMAPs) from FPL. CMAP responses exhibited a negative onset, suggesting that they originated from FPL, and this was confirmed by needle recording. Normative data has been established that may prove useful in future studies assessing pathological involvement of the anterior interosseous nerve.
