A large number of impairments and disabilities in human body are increasing day by day because of different reasons like accidents, age, paralysis attack, etc. So disabilities increase in human body and also dependency on other people the quality of life decreasing day by day. The disabled or aged people need caretaker to take care of them and to help them to do movement. So, they always need s...

This paper presents a real-time embedded framework for finger force control of upper extremity prostheses. The proposed system is based on the hypothesis that models describing the finger force and surface Electromyographic (sEMG) signal relationships of healthy subjects can be applied to amputees. An identification/estimation scheme is applied to the collected sEMG and finger force signals in ...

1092-5171/04/3102-0225 ABSTRACT: The purpose of this study was to investigate the accuracy of the proprioceptive system in swallowing as compared to fist clenching. The role of surface electromyography (SEMG) biofeedback in replicating motor strength was also evaluated. It was hypothesized that (a) strength of muscle contraction during swallowing would be less accurately replicated than in a fi...

OBJECTIVES The main objective was to determine how the depth of probe placement affects functional and resting bioelectrical activity of the PFM and whether the recorded signal might be dependent on the direction in which the probe is rotated. PARTICIPANTS The study comprised of healthy, nulliparous women between the ages of 21 and 25. OUTCOME MEASURES Bioelectric activity of the PFM was re...

In this study, the process of muscular fatigue was examined using surface electromyography (sEMG) and continuous-wave near-infrared spectroscopy (cw-NIRS) simultaneously during an isometric hand grip exercise at 50% and 75% of the maximal voluntary contraction (MVC), sustained until volitional fatigue. The mean frequency of the sEMG decreased during the whole exercise, whereas the root mean squ...

BACKGROUND AND PURPOSE Although surgery has been widely accepted as the treatment of choice for stress urinary incontinence (SUI), there has recently been an increased interest in the conservative management of this condition. The aims of this study were to test the ability of a biofeedback-assisted pelvic-floor muscle exercise (PFME) program to affect symptoms of SUI in premenopausal women and...

BACKGROUND A comparative study of treatment modalities for improving articulation in a 13-year-old child with severe spastic dysarthria associated with spastic cerebral palsy (SCP) was conducted. METHOD A multiple treatment design examined the effect of phonetic placement therapy (PPT) and sEMG-facilitated biofeedback relaxation therapy over a 6-week period. Treatment outcomes were measured u...

The aim was to classify lifting activities into low and high risk categories (according to The Danish Working Environment Authority guidelines) based on surface electromyography (sEMG) and trunk inclination (tri-axial accelerometer) measurements. Lifting tasks with different weights, horizontal distance and technique were performed. The lifting tasks were characterised by a feature vector compo...

An electrophysiological phenomenon running up and down the spine, elicited by light pressure contact at very precise points and thereafter taking the external appearance of an undulatory motion of the spine, is analyzed from its standing wave, coherence, and synchronization-at-a-distance properties. This standing spinal wave can be elicited in both normal and quadriplegic subjects, which demons...

Surface electromyography (sEMG) is a technique for recording natural muscle activation signals, which can serve as control inputs for exoskeletons and prosthetic devices. Previous experiments have incorporated these signals using both classical and pattern-recognition control methods in order to actuate such devices. We used the results of an experiment incorporating grasp and release actions w...
