SHORT REPORT ABSTRACT: Complex repetitive discharges (CRDs) are a striking, infre-quent finding on needle electromyography (EMG), but their significance is debated. This retrospective case-control study of 486 patients evaluated in a general hospital–based EMG laboratory examined the association of

Complex repetitive discharges (CRDs) are poorly understood phenomena in needle electromyography (EMG) recordings. The data presented here suggest that CRDs may mainly be a sign of motor unit reinnervation.

2023年7月15日 · Complex repetitive discharges are action potentials of a group of muscle fibers that discharge spontaneously in near synchrony in a regular, repetitive fashion. They are originated by the spontaneous depolarization of a single fiber, followed by ephaptic spread to an adjacent muscle fiber.

Complex repetitive discharges (CRDs) are a striking, infrequent finding on needle electromyography (EMG), but their significance is debated. This retrospective case-control study of 486 patients evaluated in a general hospital-based EMG laboratory examined the association of CRDs with specific diagn …

This study aimed to clarify the clinical significance of complex repetitive discharges (CRDs) identified on needle electromyography (EMG) in patients with radiculopathies. Background: CRDs are incompletely understood spontaneous needle EMG waveforms that can be seen in both myopathic and neurogenic disorders including radiculopathies.

Introduction/aims: Complex repetitive discharges (CRDs) are spontaneous electromyography (EMG) waveforms often associated with chronic neurogenic or myopathic diseases, but incidentally identified CRDs have also been described. In this study we describe the distribution and possible significance of incidentally seen CRDs in otherwise normal ...

Patients with malignancies related to idiopathic inflammatory myopathy (IIM) had a higher incidence of complex repetitive discharge (CRD) on electromyography (p = 0.008) as well as dysphagia (p < 0.001) and the absence of interstitial lung disease (p = …

2022年11月23日 · Complex repetitive discharges (CRDs) are spontaneous electromyography (EMG) waveforms often associated with chronic neurogenic or myopathic diseases, but incidentally identified CRDs have also been described. In this study we describe the distribution and possible significance of incidentally seen CRDs in otherwise normal electrodiagnostic studies.

2024年2月1日 · Complex repetitive discharges (CRDs), detected on needle electromyography (EMG), are bursts of spontaneous trains of complex polyphasic potentials that repeat at a regular frequency (range, 5–100 Hz) and terminate abruptly. The clinical significance of CRDs is unclear though they are reported in both myopathic and neuropathic conditions.
