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
variable method. Force developed in the muscles was calculated from sEMG signals using a Hill based model. The force calculated was then compared with that obtained from the MMHB
Number of subjects has now been increased to 12 from earlier 3 and inorder to measure the accuracy of sEMG model a paired t test was performedon the force obtained in the selected muscles by sEMG signal and that obtained by in has been checked by performing an inverse dynamic analysis on MMHB
