In 40 subacute stroke patients, motor recovery, proprioception, and working memory together were associated with motor imagery ability, but no single factor independently predicted it. Cross-sectional design; associations only, not causation.
Motor imagery ability was significantly correlated with motor recovery stage (r = −0.316, p = 0.047) and proprioceptive function (r = −0.422, p = 0.007), but not with working memory (p = 0.282) or time since stroke onset (p = 0.983).
When all three variables were entered simultaneously in a multiple regression, the overall model was significant (R² = 0.217, p = 0.030), but no single variable independently predicted motor imagery ability (BRS-H p = 0.402; SIAS-PS p = 0.060; BDS p = 0.278).
In an exploratory classification analysis, combining motor recovery, proprioception, and working memory distinguished high from low motor imagery ability above chance (AUC = 0.716; permutation test p = 0.032).
Single-blind randomized controlled trial. Sixty-four participants were randomized across two intervention arms and assessed at twelve weeks for the primary outcome…
