Thirty-seven patients who had undergone anterior cruciate ligament reconstruction were tested in a gait analysis laboratory at 2 and 6 weeks after surgery. Between test sessions, patients were randomly assigned to a course of either closed or open kinetic chain resistance exercises (3 sessions per week for 4 weeks). Gait analysis consisted of bilateral calculations of knee joint angle, moment, and power during level walking, stair ascent, and stair descent. An analysis of variance on the effects of training group and test session indicated that the only variable to be significantly affected by the type of exercise program was the amount of knee flexion at the beginning of step-up (P < 0.05). All other measures of knee angle, moment, and power (16 total variables) showed no significant difference between the exercise groups. All variables measured on the injured side showed significant improvement from test 1 to test 2 (P < 0.05), but the injured leg remained functionally deficient when compared with the uninjured leg. These data suggest that there are no clinically significant differences in the functional improvement resulting from the choice of open or closed kinetic chain exercises in the early period after this surgery.
37名接受了前交叉韧带重建手术的患者在术后2周和6周时在步态分析实验室接受测试。在测试阶段之间，患者被随机分配到一个封闭或开放动力链阻力训练课程（每周3次，共4周）。步态分析包括在平地行走、上楼梯和下楼梯过程中对膝关节角度、力矩和功率进行双侧计算。对训练组和测试阶段效果的方差分析表明，唯一受运动项目类型显著影响的变量是上台阶开始时的膝关节屈曲量（P < 0.05）。膝关节角度、力矩和功率的所有其他测量指标（共16个变量）在运动组之间没有显著差异。在受伤侧测量的所有变量从测试1到测试2都有显著改善（P < 0.05），但与未受伤侧相比，受伤腿在功能上仍有缺陷。这些数据表明，在该手术后早期，选择开放或封闭动力链运动在功能改善方面没有临床上的显著差异。
