脑卒中后病人可因偏瘫而发生下肢肌无力，同时可因病程的延长长期卧床及不活动或少活动而促使下肢肌无力加重，严重者可影响其多行能力．因此肌无力就成为限制脑卒中后偏瘫病人恢复活动的一个重要因素．为探讨其较为妥当的康复治疗方法，作者对下肢运动功能Ⅲ级以下、下肢肌力Ⅲ级以下者、下反运动功能Ⅳ级以上及下肢肌力Ⅳ级以上者分别采用刺激见四头肌收缩练习，股四头肌静力性渐进抗阻练习，同时配以足量的下肢促通技术，以促进患侧下肢的随意运动．结果使脑卒中后偏瘫病人的下肢肌力，编瘫步态和步行能力都有明显改善，说明本方法对下肢运动功能的恢复有一定价值．
Stroke patients may be due to hemiplegia lower limb muscle weakness, and prolonged bed rest and prolonged bed rest and activity or less to promote lower extremity muscle weakness, severe cases can affect its ability to multi-line. Therefore, muscle weakness has become an important factor in limiting the recovery activity of patients with hemiplegia after stroke. In order to explore its more appropriate rehabilitation treatment, the author of the lower limbs below the level of Ⅲ motor function, lower limb muscle strength Ⅲ below the lower anti-motor function grade Ⅳ and lower limb muscle strength Ⅳ above were used to stimulate the quadriceps contraction Practice, quadriceps progressive static resistance exercises, accompanied by sufficient amount of lower extremities to promote technology to promote the ipsilateral lower extremity of free exercise. The results of stroke patients with hemiplegia lower limb muscle strength, paralysis gait and walking ability were significantly improved, indicating that the method of recovery of lower extremity motor function has some value.
