Tensiomyography (TMG) is an innovative technique designed to evaluate the characteristics of muscle contraction in a non-invasive. The aim of this study is to test the reliability of the TMG in the measurement of contractile properties of the rectus femoris and medial gastrocnemius.
The TMG was used to measure the muscle belly displacement following the application of electrical stimulation in 32 healthy subjects. The parameters measured were: maximal muscular displacement (Dm), delay time (Td), contraction time (Tc), sustain contraction time (Ts), and relaxation time (Tr). After the analysis of intraclass correlation coefficient (ICC), there was high correlation in the parameters of the rectus femoris and medial gastrocnemius, except the medial gastrocnemius Tr.
According to the results we can conclude that the TMG is a reliable method as muscle assessment tool, even though the protocol is esencial, because it produces differences on the muscle response, as happened in our case regarding other researches.
