Abstract: Objective To examine the inter- rater reliablity of Myoton-3 Myometer in assessment of muscle tone in healthy subjects.Methods 20 healthy volunteers were assessed their muscle tone of biceps brachii and flexor carpi radialis muscles in relaxed state with Myoton-3 by 2 testers within 24 h. The frequency of damping oscillations (F value) measured by Myoton-3 was as the characteristic of the muscletone. The intraclass correlation coefficient (ICC) and Bland-Altman analysis were performed. Results The ICC was 0.72~0.88 and 0.79~0.89 in triple scan and ten-time scan pattern, respectively. The Bland-Altman analysis revealed no systematic errors between testers. ConclusionThe Myoton-3 Myometer is reliable between testers for measuring the muscle tone in healthy adults.
