Summary

Limb length discrepancy (LLD) is often missed due to compensatory movements. A new predictor index (PI) using LLD and height can help identify individuals at risk, especially those under 170 cm.

Area of Science:

  • Biomechanics
  • Human Locomotion
  • Musculoskeletal System

Background:

  • Limb length discrepancy (LLD) is underdiagnosed due to compensatory mechanisms during gait.
  • Significant LLD (>2 cm) can cause biomechanical alterations and adverse effects.
  • No studies have correlated height and true lower extremity length (TL) to quantify LLD significance.

Purpose of the Study:

  • To investigate objective evaluation methods for significant LLD.
  • To examine LLD in relation to height and TL using dynamic gait analysis.
  • To focus on kinematic and kinetic changes associated with LLD.

Main Methods:

  • Forty participants without LLD underwent gait analysis with simulated LLDs (0-4 cm).
  • Kinematic (knee flexion, pelvic obliquity) and kinetic (ground reaction force) data were collected.
  • Predictor indices (PIs) like LLD/height and LLD/TL were analyzed.

Main Results:

  • Significant knee flexion was observed in participants under 170 cm height.
  • A significant difference was noted between 3 cm and 4 cm LLD.
  • The LLD/height PI showed 80% specificity and 76% sensitivity for identifying LLD risk.

Conclusions:

  • Height under 170 cm is associated with significant changes related to LLD.
  • The LLD/height predictor index shows promise for identifying at-risk individuals.
