Subclaims¶

q3 i? After 4-week training, the BCI-SRF group improved control sequence accuracy significantly more than the Finger group, with an improvement ratio of 350%. → Yuan Liu 2024 q3 i? The TIME × GROUP interaction effect on control sequence accuracy was significant (F(2,34)=6.318, p=0.0046). → Yuan Liu 2024

q3 · i? · causal · r2

Mixed-design ANOVA of control sequence accuracy at Pre, Post, and FU in 20 healthy right-handed participants randomized to BCI-SRF or Finger training. "Significant difference in CS score (Post, p = 0.0016; FU, p = 0.0139)" was observed between groups, with the BCI-SRF group improving from 0.815 ± 0.08 to 0.919 ± 0.06 and the reported improvement ratio being 350%.

"As i g n ificant TIME × GROUP interaction effect was found (mixed- design ANOVA, F (2, 34) = 6.318, p = 0.0046) in the CS performance. Significant difference in CS score (Post, p = 0.0016; FU, p = 0.0139) was witnessed at Post and FU among 2 groups"

Discussion¶

Related Claims¶

• Training sequence accuracy improved in both groups at Post, but only the BCI-SRF group retained a significant improvement at follow-up relative to Pre — related
• BCI-SRF training increased functional connectivity between the left primary sensorimotor cortex and left middle frontal gyrus, and between right-hemisphere intrahemispheric and interhemispheric sensorimotor regions, relative to finger training — related
• BCI-SRF training increased causal effects along the SM_cortex–cerebellar–thalamus loop and enhanced bidirectional frontal-parietal causal interaction relative to finger training — related
• Four specific sensorimotor connections showed significant TIME × GROUP interaction effects, with post-training increases only in the BCI-SRF group — related
