Foot pressure distribution changes of the patient from respective control group(a ~ d) and sprain recurrence group(e ~ h) in three-dimension model (Screenshot from footscan 7.0 software). The figures showed the peak force during the walking at pre-training, 3, 6 and 12 months post training. After the balance training, the foot distribution in the control group turned to the medial side of foot(a ~ d) while the foot distribution in the sprain recurrence group turned to the medial side then reversed to lateral side of foot again (e ~ h)
