The use of hand gestures for human-computer interaction (HCI) has gained popularity due to its ability provide natural and intuitive communication in human dialogues. Hand gesture recognition (HGR) using surface electromyography (sEMG) signals is more reliable user-friendly than traditional computer vision-based methods. This study proposes a deep network named DeepTPA-Net that utilizes multi-c...

Upper-extremity exoskeletons have demonstrated potential as augmentative, assistive, and rehabilitative devices. Typical control of upper-extremity exoskeletons have relied on switches, force/torque sensors, and surface electromyography (sEMG), but these systems are usually reactionary, and/or rely on entirely hand-tuned parameters. sEMG-based systems may be able to provide anticipatory control...

A recent development in prosthetics is the osseointegrated fixation (OF), with improvements in comfort, fatigue, hip movement, and ease of prosthetic attachment reported. However, little information is available regarding muscle function. This study reports on selected gait parameters of the residual limb during the stance phase of level overground walking, focusing on muscle activity. Five mal...

Head and neck cancer treatment alters the anatomy and physiology of patients. Resulting swallowing difficulties can lead to serious health concerns. Surface electromyography (sEMG) is used as an adjuvant to swallowing therapy exercises. sEMG signal collected from the area under the chin provides visual biofeedback from muscle contractions and is used to help patients perform exercises correctly...

Based on recent advances in non-linear analysis, the surface electromyography (sEMG) signal has been studied from the viewpoints of self-affinity and complexity. In this study, we examine usage of critical exponent analysis (CE) method, a fractal dimension (FD) estimator, to study properties of the sEMG signal and to deploy these properties to characterize different movements for gesture recogn...

Lateral segmental mandibulectomy can be associated with sequelae, such as mouth opening limitation and mandibular deviation, that lead to altered oral functions (chewing, swallowing, speech) complex prosthetic management. The authors present a new protocol for surface electromyography (sEMG) motion recording help clinicians decision-making dental treatment planning mandibulectomy. clinical case...

Abstract The paper develops a prediction model based on the surface electromyography (sEMG) signals to recognize five different arm-related motions. We collect 100 groups of three-channels Biceps, Triceps, Brachioradialis as raw data set. Then we extract four features from describe characteristics motions in In pre-processing stage, compare three types EMD-based filtration methods denoise and c...

[Purpose] Lower-limb spasticity after stroke may be associated with worse functional outcome. Our study aim was to establish whether a low-dose botulinum toxin A (BTX-A) injection in subacute stroke patients can improve spasticity, gait, and daily living abilities. [Subjects] Twenty-three subacute stroke patients were randomly allocated to BTX-A treatment group (11 patients) and control group (...

PURPOSE The aim of the study was to evaluate the effects of a 6-week sEMG-biofeedback-assisted pelvic floor muscle training program on pelvic floor muscle activity in young continent women. METHODS Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Biofeedback training was continued for 6 weeks, 3 times a week. Muscle strenghtening and endurance e...
