摘要:

为了解运动训练诱发健肢膝关节肌肉疲劳对脑卒中患者姿势控制和下肢关节运动学特征的影响,纳入40名受试者,包括20例脑卒中患者和20名与之匹配的健康者。用气动肌肉驱动的下肢康复训练器使健肢膝关节执行最大等长随意收缩动作,以诱发肌肉疲劳。发现脑卒中患者与健康对照组间下肢姿势控制参数A-P动摇速度、总压力中心距离以及健侧和患侧下肢关节运动学参数触地时膝踝关节角度均存在明显差异。说明健侧下肢关节肌肉疲劳可导致双侧下肢姿势和步态动作控制能力减弱,从而增加脑卒中患者摔倒的风险。

Abstract:

This study aimed to investigate the effects of exercise-induced muscle fatigue in the unaffected knee joint on postural control and kinematic changes in stroke patients. Forty participants (20 stroke patients, 20 age-matched healthy participants) were recruited. To induce fatigue, maximum voluntary isometric contractions were performed in the unaffected knee joint in a Leg Extension Rehab exercise machine using the pneumatic resistance. We measured static and dynamic balance and lower-limb kinematics during gait. Changes in postural control parameters anteroposterior sway speed and total center of pressure distance differed significantly between the stroke and control groups. In addition, changes in gait kinematic parameters knee and ankle angles of initial contact differed significantly between stroke (paretic and non-paretic) and control groups. Muscle fatigue in the unaffected knee and ankle impaired postural control and debilitates kinematic movement of ipsilateral and contralateral lower limbs, and may place the fatigued stroke patients at greater risk for falls.
