Assessment of recovery from burn-related neuropathy by electrodiagnostic testing

The purpose of this study was to investigate the recovery of burn-related neuropathies by electrodiagnostic testing. Burn patients who presented to an American Burn Association verified burn center were interviewed and examined for clinical evidence of peripheral neuropathies by a physiatrist. Patients whom consented to participate were tested for electrodiagnostic evidence of peripheral neuropathy. Repeated studies were performed to assess for evidence of recovery. A total of 370 patients were screened. Thirty-six (9.73%) patients had clinical evidence of neuropathy. Eighteen male patients with a mean TBSA burn of 42% had nerve conduction studies performed. Etiologies of the injuries included eight flame, eight electrical, and three others. Seventy-three nerve conduction studies were performed and 58 of the tests were abnormal. The most commonly affected nerve was the median sensory (10). For patients with repeated tests, the mean time between tests was 169 days (SD, 140 days). There was a significant difference between the initial and follow-up test (McNemar's change test P=.009). In subset analysis of motor and sensory abnormalities, there was no significant difference (P=.07). The most common neuropathy identified in this cohort was the median sensory. Overall, there was improvement in the nerve conduction abnormalities examined. This study suggests that the prognosis for recovery after burn-related neuropathy is good.
