Closed-loop rehabilitation modes: large closed-loop rehabilitation mode, small closed-loop rehabilitation mode, and tiny closed-loop rehabilitation mode (The written informed consent was obtained from the individual for the publication of the image). Red arrow: tiny closed-loop rehabilitation mode, the modulation effect in the intra-hemisphere or the inter-hemisphere. Blue arrow: small closed-loop rehabilitation mode, an intervention strategy that relies on independent, comprehensive intervention that does not combine with peripheral interventions. Yellow arrow: large closed-loop rehabilitation mode, the different combinations of central intervention techniques combined with peripheral intervention technique.
