Abstract：
UNASSIGNED: Whether functionally relevant strength assessments, such as the isometric mid-thigh pull (IMTP), can be used either bilaterally or unilaterally to evaluate and guide rehabilitation progress in those with anterior cruciate ligament reconstruction (ACLR) is under-researched. This study assessed changes in peak force (PF) and asymmetry across 3 phases for bilateral and unilateral IMTP assessments in patients with ACLR. Peak isometric force from the IMTP was compared to peak torque from isokinetic dynamometry as well as against a cohort of healthy, uninjured individuals.
UNASSIGNED: Participants (ACLR, n = 15) completed bilateral and unilateral IMTP assessments at weeks 12 (baseline), 16 (phase 3), and 20 (phase 4) of rehabilitation to evaluate changes in PF and asymmetry. Asymmetry was evaluated using the asymmetry angle. Isometric data from the IMTP were compared to that from an isokinetic dynamometer as well as against a cohort of healthy, uninjured participants (n = 63) allowing for a detailed analysis of limb-specific force production.
UNASSIGNED: The PF during the bilateral IMTP increased for both the injured (0.94 N/kg) and uninjured (0.26 N/kg) limbs from baseline to phase 4, whereas the PF of the injured limb increased by 1.5 N/kg during the unilateral IMTP in the same time frame. Asymmetry values systematically reduced by ∼1% and ∼0.5% for the bilateral and unilateral IMTP tests from baseline to phase 4. Significant differences in PF of the injured limb were evident between those with ACLR and healthy controls across all phases (p = 0.022-0.001). The rate of progression in PF capacity was dependent on test type, amounting to 0.1 and 0.2 body weights per week for the bilateral and unilateral IMTP respectively. Small-to-large correlations (r = 0.12-0.88) were evident between IMTP PF and peak torque from the isokinetic dynamometer as well as between asymmetry metrics from both tests.
UNASSIGNED: The findings suggest that IMTP PF has potential for monitoring changes in PF and asymmetry during the ACLR rehabilitation progress. Both injured limb and uninjured limb show improvement in force-generating capacity, implying a positive adaptation to rehabilitation protocols. The findings highlight that ACLR is a unilateral injury that requires bilateral rehabilitation.

摘要：
■是否功能相关的强度评估，例如等距中大腿拉力（IMTP），可用于双侧或单侧评估和指导前交叉韧带重建（ACLR）的康复进展研究不足。这项研究评估了ACLR患者双侧和单侧IMTP评估的三个阶段的峰值力（PF）和不对称性的变化。将来自IMTP的峰值等距力与来自等速测力计的峰值扭矩以及健康队列进行比较，没有受伤的人。
■参与者(ACLR，n=15)在第12周(基线)完成双边和单边IMTP评估，16(阶段3),和20（第4阶段）康复，以评估PF和不对称性的变化。使用不对称角度评价不对称。将来自IMTP的等距数据与来自等速测力计的数据以及健康队列的数据进行比较，未受伤的参与者（n=63），可以详细分析特定于肢体的力的产生。
■从基线到第4阶段，双侧IMTP期间受伤（0.94N/kg）和未受伤（0.26N/kg）肢体的PF均增加，而单侧IMTP期间受伤肢体的PF增加1.5N/kg。从基线到第4阶段，双边和单边IMTP测试的不对称值系统地降低了1%和0.5%。在所有阶段，ACLR患者和健康对照者之间受伤肢体的PF存在显着差异（p=0.022-0.001）。PF能力的进展速率取决于测试类型，双侧和单侧IMTP的体重分别为每周0.1和0.2。IMTPPF和等速测功机的峰值扭矩之间以及两个测试的不对称度量之间存在小到大的相关性（r=0.12-0.88）。
■研究结果表明，IMTPPF具有在ACLR康复过程中监测PF和不对称性变化的潜力。受伤的肢体和未受伤的肢体均显示出力量产生能力的改善，暗示对康复方案的积极适应。研究结果强调，ACLR是一种需要双侧康复的单侧损伤。
