Table 3 Results from the concurrent validity analysis for the dominant hand

Dominant hand
Measurement(s)	Pearson’s product–moment correlation	ICC [95 % CI]
First measurement	0.88 (p < 0.001)	.793 [.610-.896]
Mean of the two first measurements	0.88 (p < 0.001)	.803 [.626-.901]
Mean of all three measurements	0.86 (p < 0.001)	.786 [.597-.892]
Highest value of all three measurements	0.87 (p < 0.001)	.791 [.606-.895]

Intraclass correlation coefficient (ICC) with 95 % confidence intervals [95 % CI] and Pearson’s product–moment correlation with p-values are given for one measurement, mean of two measurements, mean of three measurements and highest value of three measurements. All measurements are from session 1
