Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants are randomly assigned to either the shoulder mobilization group or the sham mobilization group, and they remain in their assigned group throughout the study. This design allows for a direct comparison of the acute effects of mobilization on muscle strength and proprioception.
Primary purpose: BASIC_SCIENCE

Brief 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Healthy university students aged 18-25 years.

Exclusion Criteria:

* Individuals with orthopedic problems in the shoulder complex.
* Those who have undergone previous shoulder surgery.
* Participants with prior knowledge of joint mobilization techniques that could affect the sham intervention.
