2011年6月1日 · In this study, we compared the control performances of force and angle, SMG and EMG during both isometric force contraction and wrist extension. These signals were used to proportionally control a cursor’s location on computer screen to cancel E from a sequence of vertically arranged letters.

2014年1月27日 · In this paper, to explore finely quantitative measures for evaluation of muscle strength level (MSL), we start with the study on quantified electromyography (EMG) and sonomyography (SMG) features of tibialis anterior (TA) muscles among hemiplegia patients.

2010年11月1日 · Electromyography (EMG) is generated by a record of the electrical discharges of active motor units (MU) during the muscle activation [1], and the root mean square (RMS) magnitude of EMG is commonly used to describe the time-domain information of …

In this study, the performances of one dimensional sonomyography (1-D SMG) and surface EMG signal in tracking the guided patterns of wrist extension were compared, and the potential of 1-D SMG for skeletal muscle assessment and prosthesis control was investigated.

1992年1月1日 · Both the electromyogram (EMG) and the muscular sound detected on the muscle surface are compound signals in which the MU FR information is contained. The aim of this work was to retrieve the dominant MU firing frequency by means of EMG and soundmyogram (SMG) cross-spectrum (CS) analysis throughout contractions of different intensities.

We have previously used the real-time change of muscle thickness detected using ultrasound, namely sonomyography (SMG), for prosthesis motor control purposes. In the present study, we further compared subjects' performance using SMG and surface electromyography (EMG) in a series of discrete tracking …

2011年6月1日 · In the present study, we further compared subjects' performance using SMG and surface electromyography (EMG) in a series of discrete tracking tasks, both with and without a concurrent auditory...

In this study, we collected EMG, MMG and SMG simultaneously from the RF muscle during isometric ramp contraction at different speeds. The purpose is to examine the continuous SMG-to-torque relationship during isometric ramp contraction, and to compare it …

2014年1月27日 · In this paper, to explore finely quantitative measures for evaluation of muscle strength level (MSL), we start with the study on quantified electromyography (EMG) and sonomyography (SMG) features of tibialis anterior (TA) muscles among hemiplegia patients.

In the present study, we further compared subjects' performance using SMG and surface electromyography (EMG) in a series of discrete tracking tasks, both with and without a concurrent auditory attention task.
