摘要：

文题释义：

疼痛特征：是指个体在感知疼痛时所表现出的多维属性，包括强度、部位、持续时间、伴随心理等。
步态表现：是指个体在行走过程中所展现的运动特征及其功能效率的综合体现，其评估通常包括步态周期中的运动学和动力学参数以及肌电特征等。

摘要
背景：疼痛会通过神经肌肉变化改变运动控制，从而导致步态改变。明确内侧半月板损伤患者的疼痛特征对步态表现的影响有利于制定个性化康复方案。
目的：探究疼痛特征对内侧半月板损伤患者步态表现的影响。
方法：使用8个惯性测量单元与常速摄像机对32例健康人群(男17例、女15例)与51例内侧半月板损伤患者(男24例、女27例)进行步态数据采集，同时评估患者的疼痛特征，如疼痛自由度、疼痛强度、疼痛心理以及疼痛阶段。独立样本t检验比对组间差异，并将疼痛特征作为自变量、步态指标作为因变量行多元线性回归分析。
结果与结论：①与对照组相比，内侧半月板损伤患者的步长、大腿/小腿/足支撑期角速度、小腿/足摆动期角速度、髋活动范围对称指数、髋/踝活动范围变异系数、股直肌支撑期肌肉贡献率显著减小(P < 0.05)，步长对称指数、膝活动范围对称指数、步长变异系数、股二头肌摆动期肌肉贡献率显著增大(P < 0.05)；②步长的预测变量是膝伸是否疼痛、疼痛强度、运动恐惧症；支撑期大腿角速度、摆动期大腿角速度、摆动期小腿角速度、股直肌支撑期肌肉贡献率的预测变量是膝伸是否疼痛；髋关节活动范围变异系数的预测变量是疼痛强度；③提示内侧半月板损伤患者的疼痛特征例如疼痛强度、运动恐惧会影响步态表现，在大腿肌肉共激活效应失衡的情况下，通过减慢运动速度、缩短步长等运动学表现可提高步态稳定性；未来的研究方向应包含疼痛管理，并开展步态再训练。

Abstract: BACKGROUND: Pain alters motor control through neuromuscular changes, leading to gait alterations. Clarifying the effect of pain characteristics on gait performance in patients with medial meniscus injuries facilitates the development of individualized rehabilitation programs.
OBJECTIVE: To investigate the effect of pain characteristics on gait performance in patients with medial meniscus injury.
METHODS: Gait data were collected using inertial measurement units and a constant velocity camera from 32 healthy people (17 men and 15 women) and 51 patients with medial meniscus injuries (24 men and 27 women). Pain characteristics such as pain freedom, pain intensity, pain psychology, and pain stage were also assessed. Independent samples t-tests were used to compare the differences between groups. Multiple linear regression analyses were performed with pain characteristics as the independent variable and gait indicators as the dependent variable.
RESULTS AND CONCLUSION: (1) Compared with the control group, the patients' step length, thigh angular velocity during the support period, calf angular velocity during the support period, foot angular velocity during the support period, calf angular velocity during the swing period, foot angular velocity during the swing period, symmetry index of the hip range of motion, coefficient of variation of the hip range of motion, and muscular contribution during the support period of the rectus femoris muscle significantly decreased (P < 0.05), and the symmetry index of the step length, symmetry index of the knee range of motion, coefficient of variation of the step length, and muscular contribution during the swing period of the biceps femoris muscle significantly increased (P < 0.05). (2) The predictive variables of step length were whether knee extension was painful, pain intensity, and kinesiophobia. The predictive variables of thigh angular velocity in the support phase, thigh angular velocity in the swing phase, calf angular velocity in the swing phase, and muscle contribution in the support phase of the rectus femoris muscle were whether knee extension was painful. The predictive variable of the coefficient of variation for the range of motion of the hip joint was pain intensity. (3) It is indicated that pain characteristics (such as pain intensity and kinesiophobia) in patients with medial meniscus injuries affect gait performance and improve stability by slowing down movement speed, shortening stride length, and other kinematic manifestations in the presence of an imbalance in thigh muscle coactivation effects. Future research directions should include pain management with gait retraining.
