Peak-ratio interference pattern analysis (peak-ratio method) is said to have a high sensitivity and to be independent of sex and age. This study was carried out to prove or disprove these findings. The peak-ratio method and qualitative motor unit action potential (MUAP) analysis were applied to the right brachial biceps and anterior tibial muscles of 44 healthy subjects, aged 23-87 years, 25 @entity16 @entity1 , aged 21-83 years, and 29 @entity121 @entity1 , aged 19-70 years. Peak-ratio parameters were independent of sex and age. They tended to be lower in the anterior tibial muscle than in the brachial biceps muscle. @entity16 @entity1 typically showed decreased peak-ratio, short time intervals and increased amplitude/turn. @entity121 @entity1 typically showed increased peak-ratio, turns/s and short time intervals. The sensitivity of the peak-ratio method was 72% for @entity16 @entity1 and 59% for @entity121 @entity1 . The sensitivity of the peak-ratio method was similar to that of the MUAP analysis in @entity16 @entity1 and higher than that of the MUAP analysis in @entity121 @entity1 . The specificity of the peak-ratio method was 80%. The peak-ratio method proved to be a valuable, supplementary electromyographic tool for the detection of @entity4094 .
