Note:
Bipedal plantar load distributions of the five regions under both states are represented as a percentage of relative plantar load and the values are expressed as mean ± SD. Statistical significances of p-values (ap < 0.05 and bp < 0.01) between both groups were determined by the independent sample t-test, while p-values (cp < 0.05 and dp < 0.01) between the static stance and the walking midstance phase in each group were determined by the paired-samples t-test.
