To investigate the association between sensorimotor function and visual assessment of postural orientation during execution of weight-bearing activities in patients with anterior cruciate ligament reconstruction (ACLR).
Cross-sectional study.
Laboratory.
Fifty-two individuals (23 women and 29 men, mean (SD) age 26.5 (6.4)) approximately 7 months after ACLR.
Sensorimotor function (proprioception, ankle dorsiflexion range of motion, and isometric muscle strength of the hip, knee, and trunk) were recorded on the injured leg. Postural orientation errors (POEs) were visually scored from video-recordings of the injured leg during execution of 5 functional tasks, and POE subscales activities of daily living (ADL) and Sport, and Total POE score were used in the analysis.
Lower hip external rotation strength was associated with higher Total POE score (B = -24.4, p = 0.041) and higher POE subscale ADL score (B = -24.9, p = 0.03). No associations between sensorimotor function and POE subscale Sport were found.
Decreased hip external rotation strength might contribute to higher scores on the POE subscale ADL and the Total POE score, in men and women following ACLR. Future studies will reveal if strengthening of hip external rotation strength improves postural orientation.
研究前交叉韧带重建（ACLR）后患者执行负重活动时感觉运动功能与姿势定向视觉评估之间的关系。
横断面研究。
实验室。
52 名个体（23 名女性和 29 名男性，平均年龄 26.5（6.4）），ACL 重建后约 7 个月。
在受伤腿上记录感觉运动功能（本体感觉、踝关节背屈活动范围和髋关节、膝关节和躯干的等长肌肉力量）。在执行 5 项功能任务期间，从受伤腿的视频记录中对姿势定向错误（POE）进行视觉评分，并在分析中使用 POE 子量表日常生活活动（ADL）和运动以及总 POE 评分。
较低的髋关节外旋力量与较高的总 POE 评分（B = -24.4，p = 0.041）和较高的 POE 子量表 ADL 评分（B = -24.9，p = 0.03）相关。感觉运动功能与 POE 子量表运动之间无相关性。
在 ACLR 后的男性和女性中，髋关节外旋力量的降低可能导致 POE 子量表 ADL 和总 POE 评分较高。未来的研究将揭示髋关节外旋力量的增强是否能改善姿势定向。
