脑卒中偏瘫膝过伸的原因分析及预防对策

Analysis of the causes and preventing methods of knee excessive extension resulted from Stroke-induced Hemiplegia

脑卒中后膝过伸发生的原因为患侧膝关节控制能力低下、下肢伸肌张力增高、本体感觉(深感觉)障碍及不科学的训练方法等。提出了良肢位摆放、膝关节稳定性训练、降低下肢伸肌张力训练、本体感觉再教育训练、延缓初次站立时间等预防膝过伸的康复对策。指出只要运用这些康复训练方法,对脑卒中偏瘫患者自早期开始进行科学、规范的康复训练,就可避免或减少膝过伸的发生,防止异常步态形成,提高下肢步行能力。

The following causes of knee excessive extension resulted from stroke-induced hemiplegia are analysised in this paper： the poor operation ability of the affected side knee, the increasing tension of lower- limb＇s extensor, the proprioceptive （deep sensory） disorder, the unscientific training methods and other factors. Rehabilitation strategies for preventing knee excessive extension are also introduced such as the position of normal limb, delaying the time of restanding,the training of improving the stability of knee, decreasing the lower-limb＇s tone and the proprioceptive reeducation. It＇s indicated that the scientific and standard training are given at the early stage, we can decrease the incidence rates of knee excessive extension abnormal gait to improve the walking ability.
