Measures of hand motor function. A: peak acceleration of wrist extension movements was significantly lower in stroke patients [displayed separately for subcortical (sc) and cortical (c) location of stroke] when compared with healthy subjects (h) (***P < 0.01, unpaired one-tailed t-tests). B: normalized Jebsen-Taylor Test score data for the affected hand was significantly higher when compared with the nonaffected hand (***P < 0.01, unpaired one-tailed t-tests). Note that this is a time based test where higher scores indicate worse performance. C: relationship between peak acceleration and normalized Jebsen-Taylor Test score. For the correlation analysis, the R² and P value are given. The number of subjects is indicated. Location of stroke is indicated but statistical testing was done across all stroke patients and healthy subjects.
