Tensiomyography (TMG) is showing as one of the most useful and reliable instrument for the musculature stiffness assessing, due to its velocity, harmlessness, sensing and high reproducibility. Taking in consideration that the maximum deformity measured by the TMG is inversely related with the muscle stiffness, and whereas this project pretends to modify that stiffness by means of the KT application, it seems obvious that TMG is the most suitable measurement instrument.
