Shoulder proprioception: a comparison between the shoulder joint in healthy and surgically repaired shoulders

Abstract

Proprioceptive mechanisms appear to play a role in stabilizing the glenohumeral joint and may serve as a means for interplay between the static stabilizers and the dynamic muscle restraints. The aim of this study was to investigate proprioception of the joint in healthy and surgically repaired shoulders. Shoulder proprioception was measured in 44 subjects who were assigned to two experimental groups: group 1, healthy subjects (n = 24); and group 2, patients who have undergone surgical reconstruction (n = 20). Joint position sense was measured with a Cybex NORM isokinetic dynamometer. The results revealed no significant differences in proprioception between the dominant and nondominant shoulders in group 1. No significant mean differences were revealed between the surgical and contralateral shoulder in group 2 under any test condition. These results imply that arm dominance in healthy individuals does not influence the proprioceptive sensibility and that reconstructive surgery appears to restore some of these proprioception characteristics.

Proprioception assessment in subjects with idiopathic loss of shoulder range of motion: Joint position sense and a novel proprioceptive feedback index

“…2 Stimuli from peripheral mechanoreceptors in joints, muscles, and skin provide the central nervous system with information regarding JPS and kinesthesia to modify motor control. 3,4 Proprioceptive mechanisms are essential in maintaining joint stability, especially for the shoulder, where stability is sacrificed for a large range of motion.…”

“…An der Schulter wurde die Propriozeption bisher vor allem bei der Schulterinstabilität untersucht [24,25,26,27,28,29,30,31,32]. So ist in der gän-gigen Literatur bis heute nur ein Artikel von Cuomo et al [33] …”
