Multi-MUP analysis of laryngeal muscles.
We performed quantitative motor unit potential (MUP) analysis of the thyroarytenoid (TA) and cricothyroid (CT) muscles, using multi-MUP-analysis in 40 healthy volunteers. The method is well tolerated, easy to perform, and examination of one muscle takes 5-10min. The mean MUP amplitude of both muscles was significantly larger in men than in women. The method can safely be used in clinical routine.
