摘要

According to the previous literature, leg length discrepancy within 2.54 cm will be compensated by individual; no management is indicated. Insole modification and external shoe modification will be given for those with leg length discrepancy between 1 to 2 inches. Surgery intervention will be given for those with leg length discrepacy beyong 5 cm or 10 to 15% shorter than that of the sound leg. However, balance change in leg length discrepacy is not well studied.
In this study, 63 young normal subjects without leg length discrepacy or neuromuscular disease were tested. Their age ranged from 19 to 32; body height ranging from 153 to 182 cm The tests were performed by having the right leg stepping on wooden board 0.5 cm thick, to created a similated leg length discrepancy. The wooden board was increasing in height piece by piece until the untolerable height. The static and dynamic balance were tested by the Weight Sensoring Balance Platform (Balance Master V2.10, NeuroCom. Corp.) respectively in every graded elevation.
There were significant differences in static balance tests in leg length discrepancy even with 1 cm of elevation (p＜0.05), but no significant difference in dynamic balance tests in different heights until the subjects could tolerate.
We also tested 20 young healthy people by elevating their bilateral lower limbs with the same height and doing the same tests. The result showed no significant difference in static and dynamic balance through whole course of equal height elevation.
We collected 7 patients with leg length discrepancy for just 1 cm; all of them have the symptom of discomfort as could be improved immediately by shoe elevation.
This might suggest that all degree of leg length discrepancy should be corrected at the point of balance.
