Clinical scores describing upper limb function. Scores in the ARAT and NHPT are shown as performance in the affected limb as a percentage of that in the intact limb. (A) Individual scores in the ARAT (A1) and NHPT (A2) are shown for every assessment performed in the first (ca.) 3 months. (B) Scores are displayed for each patient at the principal time points, along with group means. Both ARAT (B1) and NHPT (B2) were significantly improved by 1 month (paired t-tests P < 0.05 vs. initial assessment) and changes beyond this point were not significant. A number of patients had NHPT scores of 0 (or near 0) at the first assessment, whereas many had a maximum ARAT score by 3 months—thus, the ARAT is more informative of the 2 tests in the early period, whereas the NHPT becomes more sensitive later on.
