Sensitivity and specificity of single and combined clouds analyses compared with quantitative motor unit potential analysis

Introduction Turns‐amplitude, number of small segments (NSS)‐activity, and envelope‐activity clouds are three methods of electromyography (EMG) interference pattern analysis. Our objective was to evaluate the sensitivity and specificity of each individual cloud analysis and combined clouds analysis to compare with that of quantitative motor unit potential (QMUP) analysis. Methods A total of 379 muscles from 100 patients were analyzed by both...
