A New Electrodiagnostic Approach for Pectoral Nerve Conduction Studies

Anatomical studies have challenged traditional perceptions of the pectoral nerve structure, revealing a network of three branches rather than the previously accepted medial and lateral branches. This study aims to explore the implications of this updated anatomy on nerve conduction studies of the pectoral nerve and proposes a modified nerve conduction study protocol to enhance diagnostic accuracy.

A study on 25 volunteers was conducted, examining the three parts of the pectoral nerve. Electrode placement followed a detailed methodology ensuring precise data collection. The nerve conduction study was performed bilaterally, exploring latency and amplitude while addressing inter-observer variability and demographic influences.
