Teachable Moment: Complex Repetitive Discharges-Video

Video Transcription

Video Summary

In this video, the speaker discusses complex repetitive discharges (CRDs), which are spontaneous discharges recorded on needle electromyography. CRDs are considered to be generated at the muscle fiber rather than the nerve. They have a regular firing pattern, an abrupt start and end, and a wide firing frequency range. The number of spikes in the firing group can vary. CRDs are associated with chronic neurogenic or myopathic conditions and can rarely be found incidentally in muscles with no other abnormalities. Some associated disorders include neuropathic conditions like radiculopathies or polyneuropathies, and myopathic conditions like inflammatory disorders or dystrophinopathies. A reference is provided for further research. (Reference not included)
