Many studies suggested that strength training is important for improvement of motor function in individuals with hemiplegia after stroke. However, it is not clear whether a task oriented training to improve the walking in this population can increase their muscle strength. First study was conducted to compare between peak joint torque measured using 3D gait analysis and maximum isometric strength measured using hand-held dynamometer at same joint. The result revealed that peak joint torque during walking was higher than maximum isometric strength at hip extensor, knee flexor and plantarflexor muscles. Second study was conducted randomized control trial to examine the effects of task oriented gait training for muscle strengthening. These results showed maximum isometric strengths at hip extensor, knee flexor and plantarflexor muscles were increased during intervention phase with improvement of Timed Up and Go test. Generally, Progressive Resistance Training required the overload to the target muscle. Most of stroke patients can not perform the strong muscle contraction, because voluntary muscle contraction is difficult due to dysfunction of cortico-spinal tract. Task oriented gait training has a potential to increase the muscle strength instead of strength training.

许多研究表明，力量训练对改善脑卒中偏瘫患者的运动功能非常重要。然而，目前尚不清楚是否以任务为导向的训练，以改善这一人群的步行可以增加他们的肌肉力量。第一项研究是比较使用3D步态分析测量的峰值关节扭矩和使用手持式测力计测量的相同关节的最大等长力量。结果表明，在步行过程中，髋伸肌、膝屈肌和跖屈肌的峰值关节力矩高于最大等长肌力。第二项研究是随机对照试验，以检查任务导向的步态训练对肌肉强化的影响。这些结果表明，在干预阶段，髋伸肌、膝屈肌和跖屈肌的最大等长肌力随着计时和行走测试的改善而增加。一般来说，渐进式抗阻训练需要对目标肌肉进行超负荷训练。大多数脑卒中患者由于皮质脊髓束功能障碍，自主肌肉收缩困难，不能进行强有力的肌肉收缩。任务导向的步态训练有可能增加肌肉力量，而不是力量训练。
