a Exemplar wrist tracing performance at pretest for two stroke participants (S07, S10) during the triangle tracing task. The black triangle represents the mean trajectory of the controls. S07 demonstrated comparable performance to controls as indicated in the red dashed line, while S10 exhibited a large tracing error as indicated in the blue dashed line. b Boxplot of triangle tracing error at pretest, posttest and retention. Each box indicates the distribution between the 25th and 75th percentiles. The line within the box indicates the median. Whiskers represent the 1st and 99th percentile. Adjacent diamond symbols show all individual subject mean tracing errors values
