Tensiomyography (TMG) is a measuring method for detection of skeletal muscles' contractile properties.[1] Tensiomyography assesses muscle mechanical response based on radial muscle belly displacement induced by a single electrical stimulus.[2] It is performed using the TMG S2 system. A tensiomyography measurement instrument includes an electrical stimulator and data acquisition subunit (1), a digital sensor (2), a tripod with manipulating hand (3), and muscle electrodes (4) that work with an essential software interface installed on a PC.[1]
