Reliability of quantitative motor unit action potential parameters Conferences

abstract

• AbstractWe evaluated the test–retest reliability (reproducibility) of motor unit action potential (MUAP) parameters in multi‐MUAP analysis over time. Reproducibility studies are not available for needle quantitative electromyography (QEMG) performed by the same examiner. Fourteen consecutive individuals (10 men and 4 women) had repeat QEMG at 3 hours after the first examination, and seven (5 men and 2 women) had a repeat QEMG after 4–10 days. The intraclass correlation coefficient (ICC) was 87–97% with same‐day testing and 52–81% with different‐day testing. Size index and firing rate were the most reproducible, suggesting use in follow‐up multi‐MUAP studies. Muscle Nerve 30: 111–113, 2004
