Abstract

Tensiomyography (TMG) is known as non-invasive method which assesses the muscular characteristics such as contraction velocity or maximal displacement of the belly. The aim of this study was to evaluate muscular responses by TMG after muscle injury and to introduce using TMG first in Korea. This study was performed with a subject who was diagnosed with muscular injury and consent measuring and following up TMG analyses. A female patient, who was diagnosed left hip adductor muscle strain, underwent magnetic resonance imaging (MRI) and TMG at intervals of two weeks. We obtained decreased in displace maximum (Dm, 4.14 vs. 5.69) and altered curve shape in the injured muscle at the initial TMG assessment in comparison to the non-injured side. After two weeks, MRI findings and symptom were improved and Dm in the injured side increased as in the non-injured muscle. These findings suggest that a decrease in Dm indicate increased in muscle stiffness after muscle injury, and an increase in Dm as in the non-injured side after two weeks indicate recovered status. TMG may be useful as a simple and non-invasive device for monitoring muscle function after muscle injury and during the recovery.
