ACL重建术后较低的自评膝关节功能与较慢的反应时间相关
简介
该研究纳入43例ACL重建术后患者（平均术后21.6个月），通过计算机化简单反应时间测试与KOOS评分分析两者关联。结果显示，KOOS-日常生活活动及疼痛分量表得分越低，反应时间越慢，提示认知-运动干扰可能影响术后康复。临床含义：将反应时间测试纳入康复评估，或有助于低成本识别功能缺陷并制定个体化干预方案。
英文摘要
PurposeThis study investigated the relationship between simple reaction time (SRT) and self-reported knee function in individuals following anterior cruciate ligament reconstruction (ACLR). We hypothesized that slower SRT would be associated with lower scores on the Knee Injury and Osteoarthritis Outcome Score (KOOS), independent of time since surgery.MethodsIn this cross-sectional analysis, 43 participants (mean age 24.6 ± 6.3 years; 67% female; mean time since surgery 21.6 ± 13.9 months) completed a demographic questionnaire, the KOOS, and a computerized SRT assessment. The SRT test involved 10 repetitions, measuring the time required for participants to lift a finger in response to a visual stimulus on a tablet. Linear regression analyses were used to examine the association between KOOS subscale scores and SRT.ResultsRegression analyses indicated that improvements in KOOS-ADL and KOOS-Pain scores predicted faster reaction times, with our variables explaining between 11% and 21% of the variance in SRT.ConclusionsThe findings demonstrate that poorer self-reported knee function is associated with slower SRT in patients post-ACLR, suggesting that cognitive-motor interference may play a role in recovery. Incorporating SRT assessments into rehabilitation protocols could provide a cost-effective means to identify functional deficits and tailor interventions to enhance overall outcomes.
