Overview

The goal of this randomized controlled trial is to compare the immediate effects of visual, auditory, and combined feedback modalities on dynamic balance in healthy young adults. It also aims to explore whether auditory stimulation (Mozart music) can influence postural control and whether combining visual and auditory feedback provides additional benefits. The main questions it aims to answer are: * Does visual feedback (mirror) improve dynamic balance performance measured by the SEBT? * Does auditory feedback (Mozart music) improve dynamic balance performance? * Does combined visual and auditory feedback lead to greater improvements compared to single modalities? Researchers will compare three feedback conditions: visual feedback using a mirror, auditory feedback using Mozart music, and a combined visual-auditory condition. Participants will: * Be 60 healthy young adults aged 18-25 years * Be randomly assigned to one of three groups (visual, auditory, combined) * Perform the Star Excursion Balance Test (SEBT) in 8 directions * Perform the test with and without feedback modalities * Have their reach distances recorded and normalized according to their height

Interventions

Star Excursion Balance TestDIAGNOSTIC_TEST

Participants undergo three different sensory feedback conditions during the Star Excursion Balance Test (SEBT) to evaluate dynamic balance performance. The interventions include: (1) visual feedback using a mirror to provide real-time information on body alignment and movement, (2) auditory feedback using Mozart music as an external acoustic stimulus during task execution, and (3) combined visual and auditory feedback integrating both modalities simultaneously. Each condition is applied immediately during balance assessment in a randomized order, and reach distances in eight directions are recorded and normalized to participants' height.
