Brief Summary

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

Outcome Measures

Primary Outcomes (1)

• Dynamic balance performance measured by the Star Excursion Balance Test (SEBT)

  Reach distance in 8 directions Normalized reach distance (% of leg length)

  Immediately after completion of each feedback condition during the single experimental session

Study Arms (3)

Visual Feedback (Mirror)

EXPERIMENTAL

Participants perform the dynamic balance task using a mirror as a visual feedback tool. The mirror provides real-time visual information about body alignment and movement during the Star Excursion Balance Test (SEBT).

Diagnostic Test: Star Excursion Balance Test

Auditory Feedback (Mozart Music)

ACTIVE COMPARATOR

Participants perform the dynamic balance task while being exposed to auditory feedback in the form of Mozart music. The music is used as an external auditory stimulus during the execution of the Star Excursion Balance Test (SEBT) to assess its effect on postural control and balance performance.

Diagnostic Test: Star Excursion Balance Test

Combined Visual and Auditory Feedback

ACTIVE COMPARATOR

Participants perform the dynamic balance task while receiving both visual feedback through a mirror and auditory feedback through Mozart music. The Star Excursion Balance Test (SEBT) is performed under simultaneous multimodal sensory stimulation to evaluate the combined effect on postural control and balance performance.

Diagnostic Test: Star Excursion Balance Test

Interventions

Star Excursion Balance Test DIAGNOSTIC_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.
