Abstract:
ObjectiveTo observe the clinical effect of anterior seat inclination on sit-to-stand (STS) ability and balance function in patients with stroke, as well as brain functional connectivity based on functional near-infrared spectroscopy (fNIRS). MethodsFrom January, 2024 to December, 2025, 43 patients with stroke were randomly divided into control group (n = 21) and experimental group (n = 22). The control group received conventional rehabilitation combined with STS training on a flat seat, while the experimental group received conventional rehabilitation plus STS training with a 20° anterior seat inclination, for two weeks. Five-times sit-to-stand test (FTSST) and Berg Balance Scale (BBS) were assessed before and after training. fNIRS was used to detect changes in cerebral blood oxygenation in the prefrontal cortex (PFC), primary motor cortex (M1), primary somatosensory cortex (S1) and premotor cortex (PMC), and to analyze functional connectivity strength. ResultsAfter training, FTSST time shortened in both groups (t > 3.469, P < 0.01), and was shorter in the experimental group than in the control group (t = -2.065, P < 0.05); BBS scores increased in both groups (|Z| > 4.019, P < 0.01), and was higher in the experimental group than in the control group (Z = -2.250, P < 0.05). fNIRS showed that after training, the functional connectivity strength between the left M1 and the right PFC increased, as well as between the left M1 and the right S1 in the experimental group (t > 3.311, P < 0.05). ConclusionSTS training with anterior seat inclination can enhance functional connectivity in relevant brain regions, which may contribute to improvements of STS ability and balance function in patients with stroke.
