“…As previous published studies in the field, we opted to use surface electrodes to monitor shoulder muscle activity (Fischer et al , 2011, Kisiel-Sajewicz et al , 2011, McDonald et al , 2014. Activity of four shoulder muscles (supraspinatus, infraspinatus, posterior deltoid, and middle deltoid) was monitored using surface electromyography (SEMG).…”

“…Importantly, as we did not alter the electrode to underlying muscle relationship, the differences we observed between the control and glide (experimental) conditions represent the glide's effect, which is main aim of this study. Despite its limitations, SEMG has been commonly used for monitoring rotator cuff muscle activity (Fischer, Grewal, 2011, Illyes and Kiss, 2005, Kisiel-Sajewicz, Fang, 2011, McDonald, Brenneman, 2014. We did not monitor the activity of the subscapularis, anterior deltoid, teres minor and major, and scapular muscles, so it is unclear what the effects of a sustained glenohumeral postero-lateral glide are on these muscles.…”

Objectives: (1) to compare activity levels between monitored muscles during the dynamic relocation test (DRT); (2) to assess changes in muscle activation variability over 10 trials; (3) to assess within-muscle difference activity levels between the DRT and the unloaded side-lying shoulder external rotation exercise. Methods: This is a cross-sectional, laboratory-based, repeated measures study. Thirty asymptomatic individuals performed the DRT and unloaded side-lying external rotation. The order of exercises was randomized. Superficial electromyography was used for recording the supraspinatus, infraspinatus, middle deltoid, posterior deltoid, pectoralis major, and latissimus dorsi muscles. The main outcome measures were mean muscle activity, expressed as % of maximal isometric voluntary contraction. Results: We found significant between-muscles differences in activity (F t = 14.11, p < 0.001) during the DRT. Post hoc analysis suggested between-trial variability did not change over the 10 trials, (F = 18.2, p < 0.001). Within-muscle comparisons between the DRT and side-lying shoulder external rotation suggested significant differences between these exercises (F = 32.37, p < 0.001). Conclusions: considering the monitored muscles, supraspinatus, infraspinatus, pectoralis major, and latissimus dorsi are the main muscles contracting during the DRT. Of all monitored muscles, supraspinatus muscle was the only one presenting higher activity levels during the DRT when compared to the unloaded side-lying shoulder external rotation.

“…Since little is known about recovery of proximal arm function in individuals with poorer arm function post stroke [19,[25][26][27], this case report, focusing on shoulder and wrist kinematics, allows speculation about both proximal and distal motor learning occurring as a result of the ENGAGE training protocol.…”

Weakening of Synergist Muscle Coupling During Reaching Movement in Stroke Patients

Abstract: This weakened functional coupling may contribute to poor reaching performance and could be a consequence of a loss of common drive at the frequency bands as a result of interruption of information flow in the corticospinal pathway.
