Because of muscle redundancy, even single-joint motor tasks can be produced theoretically
by an infinite number of muscle force combinations. Understanding how the central nervous …

The rotator cuff performs multiple functions during shoulder exercises, including
glenohumeral abduction, external rotation (ER) and internal rotation (IR). The rotator cuff …

Guidelines are proposed for the collection, analysis, and description of electromyographic
(EMG) data. The guidelines cover technological issues in EMG recording, social aspects of …

Biomedical Signal Analysis Comprehensive resource covering recent developments,
applications of current interest, and advanced techniques for biomedical signal analysis …

The objective of this study was to quantify the coacti vation patterns of the knee flexor and
extensor muscles as part of continued efforts to identify the role of the antagonist muscles in …

Four male subjects aged 23–34 years were studied during 60 days of unilateral strength
training and 40 days of detraining. Training was carried out four times a week and consisted …

This report describes an early version of a technique for decomposing surface
electromyographic (sEMG) signals into the constituent motor unit (MU) action potential …

Understanding when and how much shoulder muscles are active during upper extremity
sports is helpful to physicians, therapists, trainers and coaches in providing appropriate …

Insight into the magnitude of muscle forces is important in biomechanics research, for
example because muscle forces are the main determinants of joint loading. Unfortunately …

Surface electromyographic (EMG) amplitude from the upper trapezius muscle is widely used
as a measure of shoulder-neck load in ergonomic studies. A variety of methods for …
