The Effect of Shoulder Mobilization on Muscle Strength and Proprioception: a Randomized Double-blind Study
The Effect of Shoulder Mobilization on Muscle Strength and Proprioception: a Randomized Double-blind Study
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.
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.
Methods:
Participants: 48 healthy university students (aged 18-25) randomly assigned to either the mobilization or sham group.
Assessments: Muscle strength (using a handheld dynamometer) and proprioception (laser pointer-assisted joint position reproduction test) were measured before and after the intervention.
Intervention: The mobilization group received passive shoulder joint glides, while the sham group underwent a placebo procedure without actual joint movement.
Conclusion:
This study aims to determine whether shoulder mobilization has immediate effects on proprioception and strength.
