Electrodiagnosis: Challenging Dilemmas in Interpretation-Session Presentation

Video Transcription

Video Summary

The video presentation features three speakers who discuss different patient cases and their corresponding electromyography (EMG) studies. The first speaker presents a case of a patient with severe carpal tunnel syndrome after carpal tunnel release. The EMG findings show no median sensory response, no median motor response, and normal ulnar and radial sensory responses. The needle part of the test showed no significant findings. The second speaker presents a case of a patient with right shoulder reverse arthroplasty who woke up unable to move her arm. The EMG findings showed decreased amplitude in the right radial motor amplitude and decreased response from the right radial sensory nerve. The needle part of the test showed some abnormalities in certain muscles. The third speaker presents a case of a patient with a history of falls and right radius fracture. The EMG findings showed reduced amplitudes in the tibialis anterior and tibial motor studies, decreased recruitment and increased duration in the needle EMG test. The speaker discusses the possible diagnoses and recommendations for further workup and management.
