Abstract:

Objective To investigate the topological alterations in brain functional networks following comprehensive treatment including brain-computer interface (BCI) training in subacute stroke subjects.
Methods From January, 2018 to June, 2019, 14 subacute stroke patients with moderate to severe upper limbs paralysis accepted routine physical therapy, occupational therapy and BCI training based on motor imagery, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Action Research Arm Test (ARAT) and Wolf Motor Function Test (WMFT) before and after treatment, while the functional connectivity (FC) was investigated with resting state functional magnetic resonance imaging.
Results The scores of FMA-UE, ARAT and WMFT increased after treatment (|t| > 5.298, Z = -3.297, P < 0.01). The FC also increased across the whole brain, including temporal, parietal, occipital lobes and subcortical regions. The FC between left piriform cortex of parietal lobule (BA5L) and right medial surface of temporal lobe (BA48R), as well as those between left precentral gyrus (BA4L) and right anterior transverse temporal gyrus (BA41R) ( r > 0.416, P < 0.05).
Conclusion Comprehensive rehabilitation including BCI training may promote recovery of motor function and activities of FC in brain in subacute stroke patients.
