摘要
背景:在缓慢步行情况下硅网支具被证明可以改善膝关节力学,但大部分的研究缺乏运动情况下支具对膝关节影响的数据支撑。目的:通过3个设计动作模拟快速运动过程中容易诱发膝关节损伤的跳跃、急停、旋转等因素,探索硅网支具是否可为膝关节提供稳定支撑,并为前交叉韧带损伤防护提供数据支撑。方法:选取12名健康志愿者分别在穿戴支具和没有穿戴支具的情况下进行屈膝下蹲、单腿跳和转向跳3个动作,将反射标记放置在受试者脚、小腿、大腿和骨盆上,应用Qualisys三维运动捕捉系统获取膝关节运动学数据,比较膝关节在是否穿戴支具情况下进行运动的差异。试验方案于2018-08-08经贵州医科大学附属医院伦理委员会审核批准,批号为2018661。结果与结论:进行各项运动时,膝关节在矢状面、冠状面和水平面的角度和角速度差异有显著性意义。穿戴支具时膝关节外翻和内旋角度均有所下降,且在单腿跳和转向跳动作中效果最为显著。穿戴支具时膝关节在水平面外旋角速度显著下降。提示穿戴支具能影响膝关节在冠状面和水平面运动力学,说明膝关节支具在动态运动过程中可以有效控制膝关节稳定性;穿戴支具可以改善膝关节峰值外翻角速度和外旋角速度的控制,有助于预防前交叉韧带损伤或帮助前交叉韧带缺陷患者。
BACKGROUND:Knee braces have been shown to improve knee mechanics in the case of slow walking,but most studies lack the data regarding the effects of a brace on knee injury in the case of lack of movement.OBJECTIVE:Jumping,emergency stop,rotation which easily induce knee joint injury during the rapid exercise were simulated to investigate whether silicon mesh braces can provide stable support for the knee joint and provide data support for the protection against anterior cruciate ligament injury.METHODS:Twelve healthy subjects were selected to perform three movements:squatting,one-leg jump and steering jump respectively with and without a brace.Reflection markers were placed on the feet,calves,thighs,and pelvis of the subjects.A Qualisys motion capture system was used to obtain kinematic data of the knee joints.Knee joint motion was compared between with and without a brace.This study was performed by Medical Ethics Committee of Guizhou College of Traditional Chinese Medicine on August 8,2018(approval No.2018661).RESULTS AND CONCLUSION:There were significant differences in the angle and angular velocity of the knee joint among sagittal plane,coronal plane,and horizontal plane.The knee joint valgus and internal rotation angle were reduced when wearing a brace in particular in one-leg jump and steering jump.The angular velocity of horizontal surface rotation also decreased obviously when wearing a brace.These findings suggest that wearing a brace can affect the motion mechanics of the knee joint in the coronal and horizontal planes.This suggests that knee joint can effectively control the stability when wearing a brace in the process of dynamic movement,and wearing a brace can improve the control of knee peak valgus angular velocity and external rotation angular velocity,which can help effectively prevent anterior cruciate ligament injury of patients with anterior cruciate ligament defects.
