Can Cushioned Shoes with Anatomical Insole Correct the Impact in Runners with Recurring Shin Splint

Shin splint injury usually takes several weeks to recover. We determine the effect of cushioned shoes with anatomical insole on impact, over pronation and mechanical strategy to impact during running in 10 k runners, over pronators, rear foot initial contact and unilateral recurrent shin splint respect bare foot running before sport return. Fourteen runners with recurrent shin splint who underwent standardized physical therapy were included. We compared by one tailed paired t-test the variables impact, rear foot over pronation angle in midstance and mechanical strategy to impact during barefoot running condition with anatomical insole and cushioned shoes running condition (α=0.05 and 1-β=80%). The impact was reduced from 6.893 g to 6.600 g (95% CI: 6.513 g-6.686 g, p<0.001) using cushioned shoes with anatomical insole condition respect barefoot running condition. The over pronation angle in midstance was reduced from 18.50° to 16.21° (95% CI: 14.29°-18.13°, p = 0.011) using cushioned shoes with anatomical insole condition respect barefoot running condition. The mechanical strategy to impact analyzed by cross correlation coefficient between cushioned shoes with anatomical insole condition with barefoot running condition was 0.77 (95% CI: 0.74-0.81, p<0.001). Running with cushioned shoes with anatomical insole in subjects with unilateral recurrent shin splint before return sport attenuates the impact and reduces over pronation. But, doesnt change the mechanical strategy to impact.
