Analysis of upper limb rehabilitation using muscle mechanics: current and future perspectives using Mechanomyography signals

Muscular-skeletal system is responsible for the movement, force and posture of the human body. It is prone to damage due to frequent engagement in different tasks. Moreover, the loss of body limb limits its proper function. Muscle mechanics provides vital information on the current status of muscular-skeletal system. It plays an extensive role in the screening of the performance rate of muscles in different activities that they undergo. This paper intends to provide an understanding of muscle mechanics in terms of mechanomyography (MMG) signals in muscle function assessment and assistive technology for upper limb. Besides analyzing the application of MMG, signal acquisition, processing, contamination, associated characteristic parameters, as well as their application in functional rehabilitation and prosthesis control are also highlighted. Due to the noise generated from adjacent muscles and body movement, future projection of advanced rendering techniques are presented here. This has also been disclosed by a death of literature that has proven required accuracy on upper limb assistive technology, lost motor functions recovery and clinical practice.
