From: Novel electrodiagnostic provocative techniques for the diagnosis of suspected tarsal tunnel syndrome
NCSs of MP and LP nerves in a 20-year-old adult with tarsal coalition using routine NCSs and Novel tests (EDCT, DST, SST) showing delayed latency of MP and LP nerves with decreased amplitude of LP nerve using routine tests (A), which was confirmed by novel tests specially MP SST where not only more latency delay was noticed but also marked drop of the amplitude of M response (B). These findings highlight how the novel tests could confirm the diagnosis of TTS by exaggerating the mild affection seen on doing routine NCSs by biomechanically challenging the nerve using stance positions (DST and SST)
