Electromyographic sensitivity of peroneus tertius relative to abductor hallucis in assessment of peripheral neuropathy.
The objective of this study was to compare the sensitivity of needle electromyography of the abductor hallucis and peroneus tertius muscles in the diagnosis of mild length-dependent peripheral neuropathy (PN). Nerve conduction studies and needle examination were performed on 50 patients with clinical evidence of mild PN. Results demonstrated that the peroneus tertius is as sensitive and is more specific than the abductor hallucis. It is particularly useful when more proximal muscles, such as the tibialis anterior and medial gastrocnemius, are not yet involved.
