Background and Aims: Medical insoles are one of the non-surgical treatments that are recommended to improve the walking pattern of individuals with leg length discrepancy. However, the long-term effect of insoles on lower Extremities dynamics in these individuals is still unclear. The aim of this study was to investigate and compare the long-term effect of both internal and external insoles of the shoe on selected dynamic variables of the lower extremities in individuals with leg length discrepancy during the stance phase of walking.
Materials and Methods: The present study was a quasi-experimental (pre-test and post-test) in which eighteen men with mild leg length discrepancy were selected and randomly divided into two equal groups of the internal insole and external insole. Selected dynamic parameters were collected by six cameras and a force plate during the stance phase of walking in the pre-test. Both groups used the insole for twelve weeks and daily for at least four hours and then participated in the post-test. Repeated measures ANCOVA was used to test the hypothesis.
Results: The statistical results showed that after twelve weeks of using both internal and, external insoles, the peak lateral pelvic tilt (internal insole: short limb P=0.041, long limb P=0.008, and external insole: short limb P=0.026, long limb P=0.007) and long leg knee (internal insole: P=0.022, external insole: P=0.007) and hip (internal insole: P=0.006, external insole: P=0.005) abduction moments decreased significantly. Also, in the external insole group, the peak anterior pelvic tilt showed a significant change in the post-test compared to the pre-test (short limb P=0.014, long limb P=0.033). However, no significant difference was observed between the two groups in the lower extremity dynamic variables (P>0.05).
Conclusion: The results of the present study showed that long-term use of both internal and external insoles with a change in the lower extremities dynamics, caused a positive adaptation in individuals with mild leg length discrepancy. However, there was no difference in the long-term effect between the internal and external insoles.
