Abstract		Chronic spasticity can lead to changes in the rheologic properties of the involved and neighboring muscles. Stiffness, contracture, atrophy and fibrosys may interact with pathologic regulatory mechanisms to prevent normal control of limb position and movement. While most known methods can not asses contractile properties of a single muscles, the Tensiomyography method is able to detect different time parameters of a chosen contracting muscle. The Tensiomyography test was performed on six patients with spastic muscles after traumatic brain injury (TBI). The measured parameters were delay time, contraction time, sustain time, relaxation time and displacement of the muscle belly. In spastic muscles Ts and Tr seems to be prolonged, which can be explained with enhanced reflex activity of the muscle, with a spread of phasic reflexes during contraction as response to single twitch stimulation and with rheologic changes.
