Abstract

Background: Limitations exist with current ACLR functional testing assessments that may be mitigated by including single-leg multi-directional testing.

Hypothesis/purpose: To compare Anterior Cruciate Ligament-Return to Sport after Injury Scale (ACL-RSI) scores, limb symmetry index (LSI) of the single-leg vertical jump (SLVJ), single-leg medial rotation hop (SLMRH), single-leg lateral hop (SLLH), and isokinetic quadriceps strength between participants with an ACLR and healthy controls and assess predictors of quadriceps strength asymmetry. It was hypothesized that ACL-RSI scores and LSIs for all tests would differ between ACLR and healthy control groups and within the ACLR group a strong correlation would exist between all outcome measures and quadriceps strength.

Study design: Cross-Sectional Study.

Methods: Twenty-six participants with an ACLR (median 13 months after surgery) and twenty-six matched healthy controls were recruited to participate in this study. Performance was assessed via SLVJ, SLMRH, SLLH, and isokinetic quadriceps strength. Between-group comparisons were made with independent t-tests and Mann-Whitney U test. Within the ACLR group, bivariate correlation and multivariate regression analysis were performed to assess the relationship between the outcome measures and quadriceps strength asymmetry.

Results: Significant between-limb differences were only identified in the ACLR group (p< 0.05): SLVJ LSI: 88.5%, SLMRH LSI: 93.6%, SLLH LSI: 92.7%, quadriceps strength LSI 80.9% - 83.9%, which were significantly lower (p <0.05) than the healthy control group. Within the ACLR group, a moderate-strong significant (p < 0.05) correlations existed with quadriceps strength and SLVJ (r=0.44-0.65), SLMRH (r =0.43-0.83), and SLLH (r=0.54-0.63); while ACL-RSI had a weak non-significant (p > 0.05) correlation with quadriceps strength (r= 0.12-0.30).

Conclusion: Single-leg multidirectional test LSIs were less in ACLR participants than matched healthy controls and all were directly related to quadriceps strength. Psychological readiness to return to sport was not related to quadriceps strength.

评估前十字韧带重建后运动心理准备、单腿垂直跳跃和非矢状单腿跳与股四头肌力量的关系。
背景:目前的前交叉韧带损伤后恢复运动功能测试评估存在一些局限性,而纳入单腿多方向测试可能会缓解这些局限性。假设/目的:比较前交叉韧带损伤后运动恢复量表(ACL-RSI)得分、单腿垂直跳(SLVJ)、单腿内侧旋转跳(SLMRH)、单腿外侧跳(SLLH)的肢体对称性指数(LSI)以及前交叉韧带损伤参与者和健康对照组之间的等速股四头肌力量,并评估股四头肌力量不对称的预测因素。研究假设:前交叉韧带损伤组和健康对照组的 ACL-RSI 评分和所有测试的 LSI 都不同,而在 ACLR 组中,所有结果测量和股四头肌力量之间存在很强的相关性:研究设计:横断面研究:本研究招募了 26 名前交叉韧带损伤患者(中位数为术后 13 个月)和 26 名匹配的健康对照者。通过SLVJ、SLMRH、SLLH和等速股四头肌力量评估其表现。组间比较采用独立 t 检验和 Mann-Whitney U 检验。在 ACLR 组内,进行了双变量相关分析和多变量回归分析,以评估结果测量与股四头肌力量不对称之间的关系:结果:仅在 ACLR 组发现了肢体间的显著差异(P< 0.05):SLVJ LSI:88.5%,SLMRH LSI:93.6%,SLLH LSI:92.7%,股四头肌力量LSI为80.9% - 83.9%,与股四头肌力量的相关性(r= 0.12-0.30)显著降低(p 0.05):结论:与匹配的健康对照组相比,ACLR 参与者的单腿多向测试 LSI 值较低,且所有 LSI 值均与股四头肌力量直接相关。恢复运动的心理准备与股四头肌力量无关。
