In Taiwan, it was estimated that at least 1,000 cases of patients require anterior cruciate ligament (ACL) reconstruction annually. Despite the improving of surgical technique, there are only 65% patients who received the ACL reconstruction return to their pre-injury level of sport. Therefore, to prevent ACL injuries in athletes is critical. The mechanism of ACL injury is greatly associated with lower limb biomechanics.~Motional analysis is the golden standard for biomechanics. However, with the advancement in technology, the investigators could explore lower limb biomechanics conveniently by wearable device. But the validity and reliability need further confirmation.~According to previous studies, the investigators could predict the possibility of ACL injuries by the change of biomechanics, such as hip adduction, internal rotation and knee valgus. Dynamic taping is a newly developing technique with better elasticity and extensibility. Studies showed that dynamic taping improve the biomechanics of knee joint. Hence, the investigators can adjust the faulty movement as soon as possible to prevent the occurrence of ACL injuries.~This study will be conducted in two years: In the first year, the investigators would verify the relation between wearable device and motion analysis and its validity and reliability. In advance, the investigators are going to observe the effect of dynamic taping in lower limb biomechanics of high-school soccer and basketball athletes. In the second year, the investigators would recruit high school soccer and basketball athletes to examine the effect of dynamic taping in lower limb biomechanics under fatigue.
