Brief summary
This study will be conducted in three years: In the first year, we would recruit male and female high school soccer athletes to observe the effect of dynamic taping on landing error scoring system under fatigue status. In the second year, we would recruit junior high school, high school and college athlete to establish a native model of single-leg and double-leg LESS, then in advanced, confirm the ability to predict ACL injuries. In the third year, we will focus on high-risk subjects evaluated by LESS and athlete with ACL reconstruction to observe the supportive effect of dynamic taping.
Detailed description
ACL injuries occur most frequently in sports involving pivoting sudden deceleration. In Taiwan, it was estimated that at least 1,000 cases of patients require ACL reconstruction annually. Despite the improving of surgical technique, there is 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. According to previous studies, the Landing Error Scoring System (LESS) is a clinical assessment tool to do field evaluation. We could predict the possibility of ACL injuries by the change of biomechanics. However, there are still many factors affecting the LESS, such as fatigue, single or double leg landing, age, sex and specific sport...etc., and comprehensive studies are absent. Dynamic taping is a newly developing technique with better elasticity and extensibility. Studies showed that dynamic taping improve the biomechanics of knee joint. Hence, we can adjust the faulty movement as soon as possible to prevent the occurrence of ACL injuries. This study will be conducted in three years: In the first year, we would recruit male and female high school soccer athletes to observe the effect of dynamic taping on landing error scoring system under fatigue status. In the second year, we would recruit junior high school, high school and college athlete to establish a native model of single-leg and double-leg LESS, then in advanced, confirm the ability to predict ACL injuries. In the third year, we will focus on high-risk subjects evaluated by LESS and athlete with ACL reconstruction to observe the supportive effect of dynamic taping.
Interventions
DEVICEdynamic taping
1. The intervention of dynamic tape can improve the LESS, which also means that we may reduce the probability of ACL injury through the intervention of dynamic tape. 2. By establish a native model of single-leg and double-leg LESS can predict the occurrence of ACL injury early and further prevent it.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Landing Error Scoring System (LESS) Score | 1st Year | Recruit senior high school soccer athletes (n=30) to observe the difference with/without dynamic taping on landing error scoring system under fatigue status. The Landing Error Scoring System (LESS) with double-leg consists of 17 items, total score is 0-19 points, whereas the single-leg consists of 14 items and total score is 0-16 points. Higher scores mean a worse outcome. |
