Predicting the Effect of Pulse Duration on Fatigue during Electrically Stimulated Non-isometric Contractions
Functional electrical stimulation (FES) is increasingly used by individuals with paralysis to regain functional movement, but muscle fatigue can limit the applicability of this technology. Mathematical predictions of power loss during electrically stimulated muscle contractions are essential when trying to not only minimize fatigue, but also determine the relative contributions of force and vel...
متن کاملEffects of pulse duration on muscle fatigue during electrical stimulation inducing moderate-level contraction.
INTRODUCTION Neuromuscular electrical stimulation (NMES) is used to prevent muscle atrophy. However, the effect of pulse duration modulation for reducing muscle fatigue and pain is unknown. METHODS Two 2-minute stimulation protocols were applied to the knee extensors of 10 healthy individuals. In 1 session, a long pulse duration (1,000 μs) and a low current amplitude (LL), set to evoke 25% ma...
متن کاملOptimization of pulse duration and pulse charge during transcutaneous electrical nerve stimulation.
The main effects and interaction of pulse duration and pulse charge on sensory, motor and painful stimulation were examined on six male subjects. Surface electrodes were placed over the triceps brachii muscle. Pulse duration was varied between 5 and 1000 µs. Peak current, muscle torque and four excitatory responses were determined. Sequential order of sensory, motor and painful stimulation was ...
متن کاملRegular Pulse Trains in Chaotic pulse Bursts
Electric field pulse bursts generated by lightning flashes are considered as sources of high radio frequencies. In this study, an analysis of pulse bursts in electric field records of 30 negative cloud to ground lightning flashes recorded in the southern coastal area of Sri Lanka is presented. Sixty-four percent (64%) of pulse bursts are typical chaotic pulse trains (CPT). Twenty-four percent (...
متن کاملGradual Muscle force potentiation during constant electrical stimulation -Dependence on stimulation current and pulse-duration
The purpose of this work is to investigate the fundamental properties of the gradual muscle force potentiation for the prediction of muscle force and body movement due to electrical stimulation. We investigated the dependence of force potentiation on both the pulse-amplitude and the pulse-duration with different ramp-up time. The experimental results showed that the force increment ratio (FIR) ...
