Estimation of muscle fatigue by ratio of mean frequency to average rectified value from surface electromyography.
Annu Int Conf IEEE Eng Med Biol Soc
August 2016
A new method to estimate muscle fatigue quantitatively from surface electromyography (EMG) is proposed. The ratio of mean frequency (MNF) to average rectified value (ARV) is used as the index of muscle fatigue, and muscle fatigue is detected when MNF/ARV falls below a pre-determined or pre-calculated baseline. MNF/ARV gives larger distinction between fatigued muscle and non-fatigued muscle.

Article Synopsis
- A new method for estimating respiratory signals from thoracic impedance is introduced, aiming to improve battery-powered, wearable monitoring devices.
- Traditional methods struggle under low current conditions due to the larger cardiac signal overshadowing the respiratory signal.
- The proposed approach uses an envelope curve derived from the cardiac T waves, resulting in higher accuracy compared to conventional techniques.
