This paper presents the parameter optimization of the fuzzy logic controller (FLC) for the Functional Electrical Stimulation (FES)-assisted elliptical stepping exercise. The FLC is used to control the cadence of the elliptical stepping exercise for smooth exercise movement. Genetic algorithm (GA) and particle swarm optimization (PSO) are used to optimize the parameters of the FLC. Both algorithms...
This paper presents a simulation of bipedal locomotion to control the stimulation pulses of functional electrical stimulation (FES) for activating muscles for paraplegic walking with spring brake orthosis (SBO). The work is a first effort towards restoring natural like swing phase in paraplegic gait through a new hybrid orthosis, referred to as spring brake orthosis (SBO). This mechanism simplifies...
This paper describes the development of a fuzzy control scheme for functional electrical stimulation, (FES)-assisted paraplegic walking with wheel walker. The simulation in this study starts with a model of humanoid with wheel walker using the Visual Nastran (Vn4D) dynamic simulation software. The humanoid model is designed based on anthropometric data. Two stimulated muscle models, quadriceps and...
This paper presents the development of paraplegic muscle model with Adaptive Neuro-Fuzzy Inference System (ANFIS). A series of experiments using Functional Electrical Stimulation (FES) with different stimulation frequencies, pulse width and pulse duration to investigate the impact on muscle output torque are conducted. The data that is obtained is used to develop the paraplegic muscle model. 500 training...
In this paper, a virtual wheelchair (WC) model is developed within Visual Nastran (VN) software environment where the model is further linked with Matlab/Simulink for control purposes. The goal is to have stable two-wheeled WC by transforming the two front wheels (caster) to the upright position. Theoretically, when the two big wheels are fed by the same torque, the WC system will only move in one...
This paper describes the effect of inclined track in an indoor rowing machine on the rowing exercise for paraplegics. The indoor rowing exercise is introduced as a total body exercise for rehabilitation of function of lower extremities through the application of functional electrical stimulation (FES). A model of the machine is developed using the Visual Nastran (Vn4D) software environment. Nine different...
