跑步机训练与体重支持(BWS)被证明可以改善中风后的运动能力。我们使用光学成像系统研究了BWS是否影响步态过程中的皮质激活。在6名皮质下中风患者中，BWS降低了感觉运动皮质(SMC)的激活，这是通过与任务相关的氧合血红蛋白水平的变化来评估的(P<；0.01)。SMC激活的变化与Cadence的变化相关(P<；0.05)。SMC激活的不对称性的改善也与不对称步态的改善相关(P<；0.05)。在5名年龄匹配的对照组中，BWS增加了总体激活(P<；0.05)，但没有改变步态参数，步态参数与SMC激活之间没有相关性。提示BWS对改善脑卒中患者的SMC功能有一定作用。
Treadmill training with body weight support (BWS) was shown to improve locomotion after stroke. We investigated whether BWS affected cortical activation during gait using an optical imaging system. In six patients with subcortical stroke, BWS lowered activation in the sensorimotor cortex (SMC) as assessed by task-related changes of oxygenated hemoglobin levels (P < 0.01). The changes of SMC activation correlated with those of cadence (P < 0.05). Improvement of asymmetry in SMC activation also correlated with improvement of asymmetric gait (P < 0.05). In five age-matched controls, BWS increased overall activation (P < 0.05) but did not modify gait parameters and there was no correlation between gait parameters and SMC activation. It is suggested that BWS might improve efficacy of SMC function in patients with stroke.
