摘要

Nowadays, research and developments of control system for spinal cord injury (SCI) using functional electrical stimulation (FES) is widely used. Restoring mobility to persons with paraplegia with regard to FES-approaches for function restoration is really challenging issues. A sarcastic view of FES is the complexity control of muscle motor function by the artificial activation of paralyzed muscles. Therefore; laboratory apparatus setup to study the knee joint control by FES electrical stimulation test with computer-controlled stimulator system consisted of Matlab/Simulink-Hasomed has been arranged. Anthropometric measurements of length of the lower limb were made. Novel wearable lower limb suit developed for FES experimental. This scenario can be seen by monitoring the sinusoidal stimulation current range muscle contraction on able-bodied (AB) subject with the simulation work was applied on knee joint swinging trajectory range-of-motion. Significant value of sinusoidal stimulation current signal is determined and regulated to vary within potential of preliminary data mining attempts to model an efficient power consume of knee joint controller. At this stage, it can improve with better technique by reduce and determine overall parameter limitation using FES.
