摘要:

目的 采用功能性近红外光谱(fNIRS)比较上肢运动功能障碍脑卒中患者单侧和双侧上肢运动时的脑网络功能连接差异。方法 2021年4月至6月,华山医院康复医学科脑卒中后上肢运动功能障碍患者40例分别行患侧单侧和双侧上肢运动,运动前后各采集fNIRS数据8 min,基于氧合血红蛋白,分析前额叶(PFC)、上肢与手功能区(H)以及初级躯体感觉区(S1)的功能活动和功能连接。结果 单侧任务后,患侧H区功能活动较运动前增强(t = -3.135, P < 0.05),患侧H区与患侧S1区、患侧H区与健侧S1区、患侧S1区与健侧S1区间功能连接强度较任务前增强(|t| > 3.218, P < 0.05)。双侧任务后,各区功能强度和各区间功能连接均无显著性差异(|t| < 2.385, P > 0.05)。单侧任务对患侧H区功能连接的增强效应高于双侧任务(t = 2.026, P < 0.05)。结论 相比双侧任务,脑卒中患者单侧上肢训练对强化相应功能脑区的即时效果更好,可对脑功能连接产生更明显的调控效应。

Abstract:

Objective To compare the functional connectivity of brain networks in stroke patients with upper limb motor dysfunction during unilateral or bilateral upper limb movement using functional near-infrared spectroscopy (fNIRS). Methods From April to June, 2021, 40 stroke patients with upper limb motor dysfunction in Department of Rehabilitation Medicine, Huashan Hospital, finished unilateral (affected) and bilateral upper limb movement. Eight-minute fNIRS data were collected before and after movement, and the functional activities and connectivity of prefrontal cortex (PFC), upper limb and hand functional area (H), primary sensory cortex (S1) were analyzed based on oxygenated hemoglobin. Results Functional activities increased in affected H after unilateral task (t = -3.135, P < 0.05), while the functional connectivity increased between affected H and affected S1, affected H and unaffected S1, and affected S1 and unaffected S1 (|t| > 3.218, P < 0.05). There was no significant difference in the functional activities and connectivity of all the areas after bilateral upper limb task (|t| < 2.385, P > 0.05). The improvement of affected H was more after unilateral task than after bilateral upper limb task (t = 2.026, P < 0.05). Conclusion Unilateral affected upper limb training is more effective on functional activities and connectivity for corresponding brain regions than bilateral task.
