摘要:

目的 采用功能性近红外光谱技术(fNIRS),探讨实时动作观察疗法(R-AOT)与视频动作观察疗法(V-AOT)对脑卒中患者观察-模仿过程中脑区激活的血氧动力学差异。

方法 选取2025年6月至9月在山西白求恩医院就诊的29例脑卒中患者,采用随机顺序、自身对照的交叉试验设计,先后接受R-AOT与V-AOT干预,中间间隔1 d以避免残留效应。通过fNIRS同步采集两阶段病灶侧和非病灶侧背外侧前额叶皮质(DLPFC)、枕叶皮质(OC)、颞叶皮质(TC)等感兴趣区(ROI)的氧合血红蛋白浓度(Oxy-Hb)变化,比较两种干预方式在不同阶段的脑区激活差异。

结果 全部监测皮质ROI经假发现率(FDR)校正后,观察期和模仿期R-AOT与V-AOT条件间无显著性差异(PFDR > 0.05)。观察期R-AOT条件下病灶侧DLPFC的Oxy-Hb变化高于V-AOT (Z = 2.183, PFDR = 0.045);病灶侧OC的Oxy-Hb变化方向与V-AOT不同,但无显著性差异(Z = 2.321, PFDR = 0.060)。模仿期,R-AOT条件下仅病灶侧TC的Oxy-Hb变化高于V-AOT (Z = 2.724, PFDR = 0.018)。

结论 R-AOT与V-AOT在脑卒中患者观察和模仿阶段可产生不同的局部皮质血氧动力学反应,其中观察阶段的差异主要见于病灶侧DLPFC,模仿阶段主要见于病灶侧TC。

Abstract:

Objective To investigate the hemodynamic differences in cortical activation during the observation-imitation process between real-time action observation therapy (R-AOT) and video-based action observation therapy (V-AOT) in patients with stroke using functional near-infrared spectroscopy (fNIRS).

Methods A total of 29 patients with stroke in Shanxi Bethune Hospital from June to September, 2025 were enrolled. A randomized-sequence, self-controlled crossover trial design was employed. Each participant received both R-AOT and V-AOT, with a one-day interval between the two conditions to minimize potential carryover effect. fNIRS was used to simultaneously record changes in oxyhemoglobin (Oxy-Hb) concentration during the observation and imitation phases in regions of interest (ROIs), including the ipsilesional and contralesional dorsolateral prefrontal cortex (DLPFC), occipital cortex (OC), and temporal cortex (TC).

Results After false discovery rate (FDR) correction across all ROIs, no significant difference was observed between R-AOT and V-AOT during either the observation or imitation phase (PFDR > 0.05). During the observation phase, Oxy-Hb was greater under R-AOT than under V-AOT in the ipsilesional DLPFC (Z= 2.183, PFDR = 0.045). Oxy-Hb showed an opposite directional pattern between the two conditions in the ipsilesional OC, but the difference was not statistically significant (Z= 2.321, PFDR = 0.060). During the imitation phase, the ipsilesional TC showed greater Oxy-Hb changes under R-AOT than under V-AOT (Z= 2.724, PFDR = 0.018).

Conclusion R-AOT and V-AOT may elicit different local cortical hemodynamic responses during the observation and imitation phases in patients with stroke. The between-condition difference during the observation phase was mainly observed in the ipsilesional DLPFC, whereas during the imitation phase it was mainly observed in the ipsilesional TC.
