摘要：

文题释义：
疼痛强度：疼痛是与实际或潜在组织损伤相关的一种不愉快的感觉和情感体验，其强度可以用目测类比评分法、数字评级法等进行量化。
动作模式：指的是运动对象在执行运动任务时，具有角度、速度、相位、方向等一系列时间、空间特征的解剖动作组合。

背景：疼痛是半月板损伤的重要体征并会影响患者的动作模式，研究疼痛对半月板损伤患者动作模式的影响有利于制定针对性的动作模式康复方案。
目的：探寻疼痛强度对外侧半月板损伤患者跨越障碍时下肢动作模式的影响。
方法：用8个惯性传感器与常速摄像机对80例外侧半月板损伤患者跨越障碍物时的下肢动作模式进行采集，以疼痛强度为自变量，分别对男性与女性行单因素方差分析。
结果与结论：①疼痛强度升高使男性摆动腿摆动相百分比、摆动腿足尖位于障碍物正上方时的支撑腿膝屈角、摆动腿摆动期髋膝相对相位角绝对值的平均值(MARP)与女性摆动腿摆动相百分比、支撑腿摆动相百分比、摆动腿支撑期髋膝MARP增大；②疼痛强度升高使男性摆动腿足跟-障碍物距离、摆动腿摆动期大腿角速度与女性摆动腿足跟-障碍物距离、摆动腿足尖位于障碍物正上方时的摆动腿膝屈角、摆动腿支撑期大腿角速度减小；③疼痛强度加重使外侧半月板损伤患者在跨越障碍物时的下肢动作模式质量下降；在面对疼痛强度加重时，男性比女性采取的积极性应对策略多，女性跌倒风险比男性大。

Abstract: BACKGROUND: Pain is an important sign of meniscus injury and affects the patient’s movement pattern. Studying the influence of pain on the movement pattern of meniscus injury patients is helpful to formulate targeted movement pattern rehabilitation programs.
OBJECTIVE: To explore the influence of pain intensity on the movement pattern of lower limbs in patients with lateral meniscus injury when crossing obstacles;
METHODS: Eight inertial measurement units and constant speed cameras were used to collect the lower limb movement patterns of eighty patients with lateral meniscus injury. The pain intensity was taken as an independent variable and one-way analysis of variance was performed for men and women separately.
RESULTS AND CONCLUSION: The swing phase percentage of the swinging leg, the knee flexion angle of the supporting leg when the toe of the swinging leg is directly above the obstacle, and the hip-knee mean absolute relative phase during the swing phase of the swinging leg in males were increased by an increase in pain intensity in males, so were the swing phase percentage of the swinging and supporting legs and the hip-knee mean absolute relative phase during the stance phase of the swinging leg in females. The leading heel-obstacle distance, the thigh angular velocity during the swing phase were decreased by an increase in pain intensity in males, so were the leading heel-obstacle distance, the knee flexion of the swinging leg when the toe of the swinging leg is directly above the obstacle, and the thigh angular velocity during the stance phase in females. Therefore, increased pain intensity reduces the quality of lower limb movement patterns when crossing obstacles in patients with lateral meniscus injury. When facing with increased pain intensity, males adopt more aggressive coping strategies than females, and females are at a greater risk of falling.

Key words: pain intensity, lateral meniscus injury, crossing obstacle, movement pattern
