  1. Data are presented as mean ± SD (range of variable) for continuous variables, and number of participants (percent of sample) for categorical variables. For participants with bilateral lesions (s05, s15, s21), lesion hemisphere was determined according to clinical presentation of the upper limb deficit. *Handedness was not collected for the first participant.
