Analysis and control of the muscle force by electrostimulation
2019
Muscle reconditioning techniques have been developed extensively in these recent years as part of the reeducation of the atrophied muscle, but also to reinforce the healthy muscle of the sedentary or sportive subject. The monitoring of the stimulated muscle by recording the electrical activity and the muscle response is necessary to detect for example the muscle fatigue and/or avoid tissue damage in the case of deconditioned muscle. The aim of this thesis is initially to analyse the muscle response in terms of force produced as response to the electrostimulation (ES). This analysis has allowed us to develop a new force model that can predict the effect of the stimulation amplitude of the cu…
Controlling muscular force by functional electrical stimulation using intelligent PID
2015
Functional Electrical Stimulation (FES) appears as a way of extremely promising research today to solve numerous pathology connected to the deficiencies of the nervous system. It is usually used for the rehabilitation of people with neurological disorders. Generally, skeletal muscles are activated by using Constant Frequency Trains (CFTs) with a fixed amplitude and inter-pulse duration. In addition, the systems of electrical stimulation do not adapt the parameters stimulation to obtain a desired force response during the rehabilitation session. The purpose of this study is to adapt automatically the stimulation parameters to the force desired by the clinician with an intelligent PID control…
Model Free Control for muscular force by Functional Electrical Stimulation using pulse width modulation
2016
International audience; Functional Electrical Stimulation (FES) is a useful technique for restoring functions for patients with neurological disorders. Muscle activities can be artificially driven through delivery of electrical pulses to skeletal muscles. Typically, muscles are activated by using constant stimulation train with a fixed parameters (amplitude, frequency and pulse width). In addition, the FES systems do not adapt the parameters stimulation to obtain a desired force response during the rehabilitation session. The purpose of this study is to investigate a real-time FES system for adapting automatically the stimulation parameters (stimulation pulse width) to track a desired force…
