This study is aimed to investigate the muscle activity changes, including fatigue effects and the symmetry of muscle activation between affected and unaffected sides during a 10-day body weight support treadmill training program using a focal ischemia rat hindlimb model. Our findings of the MPF drop after stroke might indicate fatigue effects due to the compensation loading share of the ipsilateral...
Practical Brain-Computer Interfaces (BCIs) for disabled people should allow them to use all their remaining functionalities as control possibilities. Sometimes these people have residual activity of their muscles, most likely in the morning when they are not exhausted. In this work we fuse electromyographic (EMG) with electroencephalographic (EEG) activity in the framework of a so called “Hybrid-BCI”...
Resistance exercise is essential to improve or maintain muscle performance. Vibration training has been suggested as an alternative option for muscle conditioning, aiming especially at improving muscle strength and power. Several studies link the effects of vibration training to enhanced neuromuscular stimulation, measured by electromyography (EMG) and typically ascribed to involuntary reflex mechanisms...
Prolonged static standing caused less freedom to move around and rest the muscles. This lack of flexibility in choosing body position contributes to health problems. It will accelerate fatigue besides discomfort, aching feet and swelling on leg. The aim of this study is to investigate the muscle activity and body discomfort while standing. Twelve subjects (seven females and five males) participated...
The purpose of this study, therefore, was to quantify and compare Integrated Electromyography (I-EMG) within perfuming 8-RM seated knee extension in contribution of elastic resistance and nautilus machine exercises. All data were collected within one testing session. Subjects completed 8-RM seated knee extension by three modalities of resistance exercises comprised of nautilus machine (NM), elastic...
A new method, namely Cross fuzzy entropy (C-FuzzyEn) analysis, that could enable the measurement of the synchrony or similarity of patterns between two distinct signals, was presented in this study. Tests on simulated data sets showed that C-FuzzyEn was superior to the conventional cross sample entropy (C-SampEn) in several aspects, including giving entropy definition in case of small parameters,...
Fitness centers offer a series of machines that can be used by participants independently from their training status. CardiowaveTM (CW) is a new device (Technogym R , Italy) that works simultaneously on three axes with a sliding movement of the lower limbs, activating different muscle groups according to the position maintained (i.e., Basic, B; Intermediate, I; Advanced, A; Free style, F). Thus, the...
The aim of this paper is to determine if operating has an effect on a surgeon's muscular fatigue and hand tremor. Electromyography and tremor measurements were taken throughout a day of operating from the brachioradialis (BR) and mid deltoid (MD) muscles of six head and neck surgery consultants and two ear, nose, and throat (ENT) registrars. The percent change in mean frequency (MF) of their EMG signal...
In order to assess fatigue independent amplitude-frequency correlations in EMG signals we asked nineteen male subjects to perform a series of isometric muscular contractions by extensors of the knee joint. Different amplitudes of the signal were due to randomly varying both the joint moment and the overall amplification factor of the EMG apparatus. Mean and median frequency, RMS and mean absolute...
