The Effect of Shoulder Mobilization on Muscle Strength and Proprioception: a Randomized Double-blind Study
In Brief
A clinical study evaluating Joint mobilization and Sham for Healthy Male and Female Subjects. Completed, enrolled 48 participants across 1 site.
Detailed Summary
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.
Study Details
Timeline
Interventions
Participants receive passive shoulder joint mobilization on the dominant-side glenohumeral joint. The mobilization includes inferior, anterior, and posterior glide techniques, each performed for 1 minute at a frequency of 0.5 Hz, with a 30-second rest between each mobilization. The participant is positioned comfortably to support the joint's range of motion.
In the sham intervention, the practitioner mimics the technique of shoulder mobilization but does not apply any actual movement or glide effect on the joint. The procedure is designed to closely resemble the real intervention in terms of duration, rhythm, and the practitioner's handling of the participant's shoulder. The practitioner will use superficial touch on the glenohumeral joint without applying any of the mobilizing forces necessary to move the joint.
