Muscle Recruitment Paper

The main goal of this paper is to identify a set of muscles sufficient to control a myoelectric exoskeleton knee. Internal force developed in the muscle is used as a base for muscle recruitment. A musculoskeletal model of the human body was developed in the Anybody Modelling system. The force developed in the human lower limb muscles while performing simple tasks like standing up or sitting down in a squat position were then measured using inverse dynamic analysis. The forces developed in different muscles are analysed for muscle recruitment by performing a Principal Component Analysis. Significant muscles were determined by the Method of Principal Variable.

sEMG signals were later recorded only from the muscles selected by the Principal
