Figure 6. Poorer Motor Performance Was Related to Lower % BOLD Signals in the Left Postcentral Gyrus (the Sensorimotor Cortex).

Figure 6

(A and B) Participants with post–COVID-19 (red dots) had slower performance on manual dexterity (9-Hole Pegboard dominant hand) and poorer endurance (2-Minute Walk) as shown by their lower T scores on these tasks compared with the healthy controls (blue dots) across the age spectrum, especially for the older participants on the 2-Minute Walk task. (C) Only participants with post–COVID-19 who had lesser brain activation in the left postcentral gyrus had poorer dexterity in their dominant hand; no such relationship was found in the healthy controls. (D) Across all participants, those with lesser brain activation in another region of the left postcentral gyrus had poorer endurance. BOLD = blood oxygenation level dependent; COVID-19 = coronavirus disease 2019; FWE = family-wise error.
