Fig. 2. Correlation of Spearman’s rho (r) between the ARAT-2 and the ARAT and FMA-UE, respectively, at 3 days (A), 10 days (B) and 4 weeks (C)
post-stroke. ARAT: Action Research Arm Test; ARAT-2: short version of Action Research Arm Test; FMA-UE: Fugl-Meyer Assessment of Upper Extremity.
a medium effect (< 0.49) at all time-points, and the
smallest effect size for the change was detected for the
time between 10 days and 4 weeks post-stroke (0.31).
The effect sizes for the observed time-points for the
ARAT and FMA-UE were in the range 0.44–0.48.
Largest effect sizes were noted for the change from 3
days to 4 weeks post-stroke (0.48–0.53) for all clinical
scales. The proportions of patients showing improve-
ment, deterioration or no change in assessment scores
are shown in Fig. 3.
