Short-term BCI intervention enhances functional brain connectivity associated with motor performance in chronic stroke.

ABSTRACT:

Background

Evidence suggests that brain-computer interface (BCI)-based rehabilitation strategies show promise in overcoming the limited recovery potential in the chronic phase of stroke. However, the specific mechanisms driving motor function improvements are not fully understood.

Objective

We aimed at elucidating the potential functional brain connectivity changes induced by BCI training in participants with chronic stroke.

Methods

A longitudinal crossover design was employed with two groups of participants over the span of 4 weeks to allow for within-subject (n = 21) and cross-group comparisons. Group 1 (n = 11) underwent a 6-day motor imagery-based BCI training during the second week, whereas Group 2 (n = 10) received the same training during the third week. Before
