This study was designed to compare proprioception and postural stability in patients with acute (time from injury ≤ 3 months) and chronic (time from injury > 3 months) ACL tears, and to evaluate the correlation between time interval after ACL injury and proprioception. Thigh muscle strength, postural stability, and joint position sense were compared in 48 patients with acute ACL tears and in 28 with chronic ACL tears. Maximal torque (60°/sec) of the quadriceps and hamstring was evaluated using an isokinetic testing device. Postural stability was determined from the anterior-posterior (APSI), medial-lateral (MLSI), and overall (OSI) stability indices using stabilometry. Joint position sense was also tested by reproduction of passive positioning (RPP). Muscle strengths and stability indices on both the involved and uninvolved sides were similar in the acute and chronic ACL tear groups. RPP on the involved side was significantly greater in the chronic than in the acute ACL tear group (7.8° vs. 5.6°, P = 0.041). Two of three stability indices (APSI, OSI) and RPP were significantly greater on the involved than the uninvolved side in the chronic ACL tear group.
本研究旨在比较急性（受伤时间≤3个月）和慢性（受伤时间>3个月）前交叉韧带撕裂患者的本体感觉和姿势稳定性，并评估前交叉韧带损伤后时间间隔与本体感觉之间的相关性。对48例急性前交叉韧带撕裂患者和28例慢性前交叉韧带撕裂患者的大腿肌肉力量、姿势稳定性和关节位置觉进行了比较。使用等速测试装置评估股四头肌和腘绳肌的最大扭矩（60°/秒）。使用稳定测力法从前-后（APSI）、内-外（MLSI）和整体（OSI）稳定性指数确定姿势稳定性。还通过被动定位再现（RPP）测试关节位置觉。急性和慢性前交叉韧带撕裂组中，患侧和未患侧的肌肉力量和稳定性指数相似。慢性前交叉韧带撕裂组患侧的RPP显著大于急性前交叉韧带撕裂组（7.8°对5.6°，P = 0.041）。在慢性前交叉韧带撕裂组中，三个稳定性指数中的两个（APSI、OSI）以及RPP在患侧显著大于未患侧。
