简要总结
This randomized, double-blind study examines the acute effects of shoulder mobilization on muscle strength and proprioception in healthy individuals. Forty-eight participants (aged 18-25) were randomly assigned to either a mobilization or sham intervention group. Muscle strength and proprioception were assessed before and after treatment. The mobilization group received passive shoulder joint glides, while the sham group underwent a placebo procedure. The study aims to determine whether mobilization affects strength and proprioception immediately.
详细描述
Summary of the Study
This randomized, double-blind study investigates the acute effects of shoulder joint mobilization on muscle strength and proprioception in healthy individuals compared to a sham intervention.
Background:
The shoulder joint is highly mobile and prone to injury, with rehabilitation often including manual therapy techniques like joint mobilization. Mobilization may enhance joint stability, neuromuscular control, and proprioception by stimulating mechanoreceptors. However, its immediate effects on shoulder proprioception and strength remain unclear.

研究组 & 干预措施
Mobilization Group
Participants receive passive shoulder joint mobilization targeting the glenohumeral joint.
干预措施: Joint mobilization (Other)
Sham Group
Participants undergo a placebo procedure where the practitioner mimics the mobilization technique without applying actual joint movement or distraction.
干预措施: Sham (Other)
结局指标
主要结局
Proprioception
时间窗: Immediately after intervention
Laser pointer-assisted joint position reproduction test for shoulder: A laser pointer is strapped 5 cm above the lateral epicondyle. Participants actively move their arm to a predefined position (90° flexion or abduction), and the laser projection is marked. After lowering their arm and closing their eyes, they attempt to replicate the same position. The difference between the initial and reproduced positions (in millimeters) is measured
Proprioception
时间窗: Before the intervention
