Summary

This observational study aims to investigate the effect of heel lift insole on kinematics and kinetics of the lower limb and lumbar spine among healthy individuals.

Conditions

  • Healthy Individuals

Interventions

DIAGNOSTIC_TEST

Record EMG maximum amplitude from bilateral erector spinae, rectus femoris, and medial and lateral gastrocnemius muscles.

Conduct measurements under two conditions: Condition 1: Standing with standardized flat shoes. Perform three trials for each participant. Calculate and record the mean as baseline data. Condition 2: Standing with a standardized heel lift insole inside the flat shoes. Conduct three trials. Record the mean for comparative analysis.

DIAGNOSTIC_TEST

Photograph participants from anterior and lateral views to assess knee valgus angle and lumbosacral angle.

Capture two sets of photographs for each participant: Set 1: Wearing flat shoes. Set 2: Wearing the heel lift insole inside the flat shoes. Compare knee valgus angle and lumbosacral angle under both conditions. Ensure consistency and reliability by following standardized protocols and performing repeated measurements. Analyze the effects of heel lift insoles on muscle activity and postural alignment.
