Brief Summary

Brief Summary (for ClinicalTrials.gov) This cross-sectional observational study aims to identify independent determinants of static and dynamic balance in healthy young adults using a multidimensional assessment framework. A total of 119 healthy participants (mean age 22.6 ± 1.5 years; 61.3% female) completed standardized static balance tests (Stork Balance Test and Tandem Stance Test under eyes-open and eyes-closed conditions) and a dynamic balance test (Y-Balance Test for right and left limbs). Candidate explanatory factors include foot posture (Foot Posture Index-6), body composition assessed by bioelectrical impedance analysis, general muscle strength (dominant hand grip strength), weight-bearing ankle dorsiflexion range of motion (knee-to-wall/weight-bearing lunge test), functional lower-limb strength (30-second sit-to-stand test), sex, and cognitive performance (Stroop Test Part 5). Multiple linear regression model (enter method) was used to determine which factors independently predict static and dynamic balance outcomes. Findings are expected to clarify which structural, functional, and cognitive variables most strongly contribute to balance performance in healthy young adults, informing targeted assessment and prevention strategies.

Outcome Measures

Primary Outcomes (3)

• Stork Balance Test (Eyes Open and Eyes Closed) Time

  Time (seconds) maintained in the Stork Balance Test under eyes-open and eyes-closed conditions. Higher values indicate better static balance.

  At a single study visit (baseline)

• Tandem Stance Test (Eyes Open and Eyes Closed) Time

  Time (seconds) maintained in the Tandem Stance Test under eyes-open and eyes-closed conditions. Higher values indicate better static balance.

  At a single study visit (baseline)

• Y-Balance Test Composite Score (Right and Left)

  Y-Balance Test composite score (%) for the right and left lower limbs, calculated from reach distances and normalized to limb length. Higher values indicate better dynamic balance.

Secondary Outcomes (9)

• Foot Posture Index-6 (FPI-6)

  Baseline (single assessment session)

• Knee-to-Wall Test (KTW)

  Baseline (single assessment session)

• 30-Second Sit-to-Stand Test

  Baseline (single assessment session)

• Dominant Hand Grip Strength

Interventions

Participants did not receive any intervention as part of the study; they only underwent assessments. DIAGNOSTIC_TEST

Participants completed standardized static balance tests (Stork Balance Test and Tandem Stance Test under eyes-open and eyes-closed conditions) and dynamic balance assessments using the Y-Balance Test for both right and left limbs. In addition, the following measurements were obtained: foot posture (Foot Posture Index-6), body composition via bioelectrical impedance analysis, general muscle strength (dominant hand grip strength), weight-bearing ankle dorsiflexion range of motion (knee-to-wall/weight-bearing lunge test), functional lower-limb strength (30-second sit-to-stand test), sex, and cognitive performance (Stroop Test Part 5).
