Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this cross-sectional study is to examine the differences in proprioception sensation depending on sex and dominant side factors in healthy volunteers. Hypothesises:

H0: Shoulder proprioception sensation does not change depending on sex and dominant side factors.

H1: Shoulder proprioception sensation varies depending on sex and dominant side factors.

Shoulder proprioception measurement using isokinetic dynamometer

A Cybex brand isokinetic dynamometer \[Cybex NORM®, Humac, CA, USA\] was used for shoulder proprioception assessment. Active Joint Position Sensation (AJPS) was evaluated to examine proprioception. AJPS was measured in the sitting position. The target angle was 30° external and 30° internal rotation. The participant was positioned with the elbow in 90° flexion and the wrist in the neutral position. The dynamometer was fixed at 0° to ensure the same starting position for each participant during trials and evaluations. Before starting the test, 3 trials were performed and then the participants were asked to find the target angle 3 times. The amount of error between the target angle and the angle found by the participant was used to describe the accuracy of the AJPS. The arithmetic mean of the result of the 3 tests was recorded for use.
