Abstract

The Relationship Between Proprioceptive Perception and Visual Reaction Based on Shoulder Joint Angles in Individuals With Autism Spectrum Disorder

Introduction: This study aims to examine the relationship between proprioceptive perception and visual reaction time based on shoulder joint angles in individuals with autism spectrum disorder (ASD).

Methods: The study involved 25 male participants with ASD. Proprioception was measured using a digital inclinometer, and visual reaction time was assessed using the Blazepod device. Measurements were performed daily for 14 days at the same time, and the best of two trials was recorded. Data were analyzed using SPSS 26.0.

Results: A moderately positive and statistically significant relationship was found between proprioception at a 60° shoulder angle and visual reaction time (r = .551, p < .05). No significant correlation was found at 90° and 120° angles.

Discussion: These findings suggest that proprioceptive input at specific joint angles may have a greater impact on motor responses in individuals with ASD. The 60° angle appears to be a functional position. The results are consistent with existing literature on sensory processing differences in ASD.

Conclusion: The study concludes that proprioceptive sensitivity is related to motor performance in individuals with ASD and that therapy programs should be tailored to account for individual angular differences.
