production/torque relationship with onset of fatigue during voluntary muscle contractions and restoration of functional movement in paraplegic patients through FES evoked muscle contraction. Understanding the initiation of movement in animals and central role of muscle

Myoelectric signal remains the gold standard to objectively monitor muscular activities despite the tedious task of separating cross talk from contractions. This work evaluated the signal characteristics during FES-evoked contractions in muscle force and fatigue assessment to reiterate its inherent setbacks despite overwhelming research efforts to improve its signal to noise ratio. It was observed that researchers often had to tradeoff either i) aesthetic and compact design for complex electrical circuit to remove noise and ii) transcutaneous for invasive percutaneous stimulation to eliminate stimulus artifact in order for characteristic Mwave of evoked EMG to be significant in FES evoked contraction analysis. We aim to stimulate researchers’ interest to investigate alternative and robust paradigms myoelectric signal analysis and future applications of FES system to gain expected acceptance in clinical settings and outdoor activities.
