Abstract of Polish Research on the efficacy of massage in Physical Therapy using EEG / MMG. The study focused specifically on effects not directly related to the muscle being manipulated. This research was published in the Journal of Bodywork and Movement Therapies on April 13, 2009. It offers direct evidence of the Tensegrity principle being active in bio-mechanical structure through fasciae and muscle relationships.
Abstract
Based on a tensegrity principle, direct or indirect connections between fascia or muscles that stretch the aponeurosis or intermuscular septum may allow the transfer of tension over long distances, without loss of muscle force produced during rest and activity. The present study aimed to test the effect of massage on electrical (EMG) and mechanical (MMG) activities of a muscle lying distant, but indirectly connected to, the massaged muscle. Thirty-three healthy men participated in the study. To record the activity of the middle deltoid muscle the brachioradialis was massaged, and for the tensor fasciae, the peroneal muscles were massaged. An EMG/MMG hybrid probe was used to detect EMG and MMG signals from the middle deltoid and tensor fasciae lata muscles. The EMG amplitude increased during massage in the tensor fasciae lata only, while the MMG amplitude increased significantly in both muscles. It was concluded that there was an electrical as well as a mechanical response of muscle connected indirectly by structural elements with the muscle being massaged indicating an application for the tensegrity principle in massage therapy. It also has a practical importance, because it provides a means for a physiotherapist to influence adverse muscle tension by massaging another distant muscle.
