Analysis Data

The purpose of this study was to devise a tilt sensation measurement method to evaluate ankle proprioception and to examine its reliability. It was also used to determine the relationship among tilt sensation abilities, physical development, and lower limb injuries in junior athletes. Experiment 1 involved 22 university students. The minimum angle at which a tilt could be sensed while standing on both feet was determined, and measurements were taken again to examine reliability. Experiment 2 involved 40 junior athletes, where the minimum angle for tilt sensation was obtained, and medical checks were conducted to assess injuries in the knee, lower leg, and foot. Reliability studies showed a moderately significant correlation between the first and second sessions. The proportion capable of sensing a tilt of 1.1° and 1.6° was significantly higher in junior high school students than in elementary school students. The group unable to sense a tilt of 1.6° and 2.1° had a significantly higher positive rate of knee injuries compared to the sensed group among junior high school students. Our findings suggested that a reduced tilt sensation ability was associated with knee injuries in junior high school students. Utilizing our devised tilt sensation assessment could play a crucial role in preventing and detecting early injuries in junior high school students.

本研究旨在设计一种用于评估踝关节本体感觉的倾斜感测量方法，并检验该方法的信度，同时探究倾斜感能力、身体发育状况与青少年运动员下肢损伤之间的关联。实验1招募了22名大学生，测定其双足站立时可感知倾斜的最小角度，并开展重复测量以检验信度。实验2招募了40名青少年运动员，测定其倾斜感最小角度，并通过医学检查评估膝部、小腿及足部的损伤情况。信度分析结果显示，两次测试间存在中等程度的显著相关。可感知1.1°与1.6°倾斜的受试者比例，初中生群体显著高于小学生群体。在初中生群体中，无法感知1.6°与2.1°倾斜的组别，其膝部损伤阳性率显著高于可感知该角度的组别。本研究结果表明，倾斜感能力下降与初中生的膝部损伤存在关联。本研究设计的倾斜感评估方法，可在初中生的运动损伤预防与早期损伤筛查中发挥重要作用。
