Forearm supports reduced shoulder flexion torque by 90% compared to no support.
This study investigated differences in elbow and shoulder flexion angles in an assembly task.
Generally, there was an increase in muscle activity as the degree of shoulder flexion increased.
It was mentioned that the patients experienced significant improvement in their range of movements for shoulder flexion and abduction of the affected limb.
In general, endurance time decreased with an increase in shoulder flexion angle up to 120° and then it increased.
Common industry and ergonomic guidelines suggest a general posture of reduced shoulder flexion and neutral humeral rotation.
Data were used to generate two stepwise multiple regression models for predicting isokinetic shoulder flexion and exertion strength across the various exertion parameters.
The purpose of this investigation was to assess factors influencing isokinetic shoulder strength and to develop predictive equations for isokinetic shoulder flexion and extension strength using isometric strength.
Fifteen women performed a set of concentric isokinetic and isometric shoulder flexion and extension maximal exertions across a series of movement planes, angular velocities, and grip types.
Results: Data analysis using paired t-tests showed significant improvements in shoulder flexion, shoulder abduction, elbow flexion, elbow extension,and wrist extension.
Therefore, the present study aimed to investigate the intra- and inter-session reliability of scapular muscle activity during maximal isokinetic shoulder flexion and extension.
