Concurrent validity of an immersive virtual reality version of the Box and Block Test to assess manual dexterity among patients with stroke

Table 2 Intraclass correlation coefficient between second and third trial of the BBT-VR

	Trial 1	Trial 2	Trial 3	ICC (2vs3)	p-value (Anova)
Healthy participants
Dominant hand	44.3 ± 16.20	51 ± 16.09†	54.5 ± 17.02	0.89*	< 0.001
Non dominant hand	47.8 ± 18.23	53.7 ± 19.28†	55.2 ± 22.3	0.94*	< 0.001
Patients with stroke
Less affected hand	24.5 ± 9.06	31.9 ± 10.31^†	34.5 ± 9.36	0.84*	< 0.001
Paretic hand	17 [14–29]	18 [13.5–30]†	25 [17–33]	0.87*	0.04

ICC = Intraclass correlation coefficient; 2 = Trial 2; 3 = Trial 3; results are presented as means ± standard deviation or median [quartile 1–quartile 3]; * = significant p-value regarding ICC; ^† = significant p-value between trial 1 and 2 (post-hoc); ^‡ = significant p-value between trial 2 and 3 (post-hoc)
