Virtual Reality MT: Virtual Reality Mirror Therapy; Conventional MT: Conventional Mirror Therapy; Indep. Task: Independent Tasks; No Independ. Tasks: No independent tasks; No rel. Tasks: No relevant tasks; No use AH: No use of Affected Hand; Use AH: Use of the Affected Hand; Use AH with support: Use of the Affected Hand with support; Use AH with grasp: Use of the Affected Hand with grasp. Independent task, no-independent task, no relevant task, non-use AH, Use AH with support, and use AH with grasp are expressed in total number of tasks. Efficacy, task time and discomfort are expressed in a 4-point scale (1–4; 1: lowest score, 4: highest score). Values are expressed in median (interquartile range; (IQR). + Statistically Significant Difference (intergroup difference assessed with Mann-Whitney U-test) when p value < 0.05. * Statistically Significant Difference (pre-post intragroup difference assessed with Wilcoxon’s test) when p value < 0.05.
