Deficits in reaction time, decreased self-reported knee function, and elevated levels of injury-related fear have been observed in individuals who sustain anterior cruciate ligament injury. Understanding the relationship between these variables may provide the impetus to further investigate effective intervention strategies to address these deficits in individuals after anterior cruciate ligament reconstruction (ACLR).
To examine the relationship between injury-related fear and lower-extremity visuomotor reaction time (VMRT) in individuals with a history of ACLR. A secondary purpose was to determine the relationship between self-reported knee function and lower-extremity VMRT in individuals with a history of ACLR.
Cross-sectional study.
Laboratory.
Twenty participants between the ages of 18-35 years, with history of unilateral ACLR within the last 10 years, who injured their knee playing or training for organized or recreational sports.
Scores on the athlete fear avoidance questionnaire, the fear-avoidance beliefs questionnaire (FABQ), the knee injury and osteoarthritis outcome score, and reaction time (in seconds) on the lower-extremity VMRT task using the FitLight Trainer™, bilaterally. Spearman Rho correlations examined the relationship between the dependent variables.
There was a moderate positive correlation between VMRT and FABQ-total (r = .62, P < .01), FABQ-sport (r = .56, P = .01), and FABQ-physical activity (r = .64, P < .01) for the injured limb. Correlations between FABQ scores and VMRT for the uninjured limb were weak positive correlations (r = .36-.41, P > .05). Weak correlations between the osteoarthritis outcome score subscales, athlete fear avoidance questionnaire, and VMRT were observed for the injured limb (P > .05).
Individuals with a history of ACLR who exhibited elevated levels of injury-related fear demonstrated slower VMRT. There were no relationships between self-reported knee function and VMRT. Future research should explore interventions to address injury-related fear and VMRT in individuals after ACLR.
在经历前交叉韧带损伤的个体中，已经观察到反应时的缺陷、自我报告的膝关节功能下降以及与损伤相关的恐惧水平升高。了解这些变量之间的关系可能会促使我们进一步研究有效的干预策略，以解决前交叉韧带重建（ACLR）后个体的这些缺陷。
检查 ACLR 病史个体中与损伤相关的恐惧与下肢视动反应时（VMRT）之间的关系。次要目的是确定 ACLR 病史个体中自我报告的膝关节功能与下肢 VMRT 之间的关系。
横断面研究。
实验室。
20 名年龄在 18-35 岁之间的参与者，单侧 ACLR 病史在过去 10 年内，在为有组织或娱乐性运动而进行的比赛或训练中受伤。
运动员恐惧回避问卷、恐惧回避信念问卷（FABQ）、膝关节损伤和骨关节炎结局评分、使用 FitLight Trainer™进行的下肢 VMRT 任务的反应时间（秒），双侧。Spearman Rho 相关性检验了因变量之间的关系。
受伤肢体的 VMRT 与 FABQ-总（r =.62，P <.01）、FABQ-运动（r =.56，P =.01）和 FABQ-体力活动（r =.64，P <.01）之间存在中度正相关。未受伤肢体的 FABQ 评分与 VMRT 之间呈弱正相关（r =.36-.41，P >.05）。受伤肢体的骨关节炎结局评分亚量表、运动员恐惧回避问卷和 VMRT 之间存在弱相关性（P >.05）。
表现出较高水平与损伤相关的恐惧的 ACLR 病史个体的 VMRT 较慢。自我报告的膝关节功能与 VMRT 之间没有关系。未来的研究应该探索针对 ACLR 后个体的与损伤相关的恐惧和 VMRT 的干预措施。
