Electromyography and Pudendal Nerve Terminal Motor Latency

Objective evaluation of the pelvic floor is an important part of the assessment of patients with defecation disorders. In this assessment, EMG is used to diagnose PSR and to assess the effect of biofeedback treatment. For practical reasons, surface EMG using an anal plug is usually preferred in this assessment. The role of PNTML and testing of anorectal sensation with electrosensitivity in constipated patients remains unclear.
