Fig. 5From: Reliability, validity and discriminant ability of the instrumental indices provided by a novel planar robotic device for upper limb rehabilitationIntra-session reliability analysis in stroke patients: robotic indices assessing the whole task. Blue lines represent the statistical analysis of the first session (test), while green lines represent the statistical analysis of the second session (retest). The symbols *, ** and *** represent a statistically significant difference between repetitions, with a p value less than 0.05, 0.01 and 0.001, respectivelyBack to article page
