摘要
The effect of a simulated leg length discrepancy on foot loading patterns and gait cycle times in normal individuals was investigated. Thirty feet of 15 normal volunteers were evaluated. Leg length discrepancy was simulated using flexible polyurethane soles. As leg length discrepancy increased, the total loading increased from 35.31 to 37.99 kg/cm(2)/sec, forefoot loading increased from 15.58 to 19 kg/cm(2)/sec, hindfoot loading remained the same. All subjects, except females with middle loading patterns, demonstrated increased hallux loading. The contact phase of gait decreased from 22% to 13%, the midstance phase remained the same, the propulsion phase increased from 44% to 50%. All findings were statistically significant. Leg length discrepancy has significant effects on the foot. Different adaptive loading patterns amongst subsets of individuals are seen.
