Rehabilitation Training Analysis Based on Human Lower Limb Muscle Model

Abstract

Human lower limbs are closely related to human motor ability, so lower limb muscle injury will affect human motor ability. Therefore, we need to establish an effective muscle model to analyze the muscle output in rehabilitation training. Based on the analysis of human anatomy of human lower limb musculoskeletal connection, with calves, quadriceps, hamstrings muscle is a dynamic model of the three muscles, in view of the quadriceps and hamstring muscles work together in the situation of hip flexion and extension, using Crowninshieldt established based on the smallest muscle force of PCSA optimization objective function of solving the two muscles is optimized, And conducted related experiments on general fitness equipment, The BIOPIC multi-channel physiological signal acquisition instrument and Angle sensor are used to collect the muscle emg signal and lower limb position information of the tester. Then, according to the position information collected, the muscle output is calculated by the lower limb muscle model, and compared with the muscle force obtained by the electromyography signal. The results of the two are consistent.
