The investigators also explored if there is any association between lower limb injuries and balance or foot pressure. The study subjects, divided into the lower limb injured group and the healthy group, did a balance test after mild stepping. Treadmill gait analysis system (FDM-TB, Zebris, Germany) was used to measure displacement surface area of the pressure center (eyes closed and eyes opened), displacement pathway of the pressure center (eyes closed and eyes opened), walking stance phase (left and right foot), walking step ratio, and walking symmetry. Two-factor repeated measure ANOVA (SPSS 12.0) was used for comparing the two groups’ balance ability and foot pressure before and after mild stepping. The significant level was set at 0.05. At the walking stance phase (right foot), the two groups’ balance (athletes and college students)center displacement distance differed significantly both before and after mild stepping (F= 10.79, p <.05). When comparing between the healthy and the lower limb injured groups, their balance center displacement distance at the walking stance phase (right foot) also differed significantly before and after mild stepping (F= 13.93, p <.05). For the difference between before and after static balance, the athlete group before mild stepping was better than the non-athlete group in terms of balance stability, but after mild stepping, the non-athlete group’s balance ability was substantially improved. For the lower-limb injured group, their balance before mild stepping was better than the healthy group, but after mild stepping, their balance stability dropped significantly. Taken together, in a short-term, no significant difference in balance or foot pressure was found in athletes from doing mild stepping. Neither did mild stepping cause significant differences between the lower-limb injured and the healthy groups in balance performance.
