Values of instrumental indices used to assess upper limb reaching motion (10^th – 90^th percentile range) in healthy subjects (N = 25) and the sample of stroke patients enrolled in this study (N = 44). Statistical comparison was assessed by the non-parametric Mann-Whitney U test. Effect size is reported for significant differences. Legend: ^* p < 0.05; ^** p < 0.01; ^† p < 0.001
