¹ Principal component analysis (PCA) factor loadings, variance explained, and coefficients for all investigated variables are presented. On the left is the list of variables, where L stands for the contralateral side and D for ipsilateral side of the lesion; performance results are shown for the second and third week, respectively. Factor loadings greater than 0.3, are represented in bold.
