In this article, a new electrodiagnostic approach is described for patients with Morton's neuroma. The method based on the anatomic fact that two branches of common plantar interdigital nerves innervate lateral side one toe and medial next one. This study included 20 normal subjects (aged 28-58 years, 10 men women) 4 neuroma 44-52 women). adjacent innerve were stimulated superficially separately half covered piece medical tape. recordings obtained posterior tibial nerve at malleolus needle electrodes. Thus, difference in latencies sensory action potentials electrode was measured. From subjects' data, it determined latency value above 0.17 milliseconds (mean +/- 2.5 SD) abnormal. All showed abnormal interlatency values. method, which we have developed, more sensitive, simple to use, does not require extra equipment, cause excessive pain. We suggest between useful sensitive diagnosis
