Dr. Tatsuya Abe
Vice President, National Hospital Organization Hakone Hospital in Japan

This video provides a detailed explanation of how to perform Motor Unit Number Estimation (MUNE), a technique that uses electromyography (EMG) to estimate the number of functional motor units within a muscle. The procedure is demonstrated using the Multiple Point Stimulation Technique, accompanied by actual footage of the procedure.
Target Muscle: Abductor Pollicis Brevis (APB)
