Introduction:
We describe a simple and quickly applied electrodiagnostic method for confirming the diagnosis of interdigital neuropathy caused by Morton neuroma (MN).
Methods:
Interdigital nerves II-III and III-IV were stimulated with surface electrodes simultaneously touching the lateral side of 1 toe and the medial side of the other. Recording was also made with surface electrodes. The results of 20 normal controls and 14 patients with MN were evaluated.
Results:
The amplitude and peak latency values elicited in the patients as well as the interside differences revealed an acceptable abnormality rate between 57.1% and 71.4%.
Conclusions:
Although the most popular and effective method of MN diagnosis is clinical evaluation supported by imaging, electrophysiological studies can, in selected patients, provide valuable information.
