	iNPH (n = 20) mean ± SD, range	Control (n = 20) mean ± SD, range	p-value
Upper limb SP (ms)	55.3 ± 17.7, 32.9–84.3	78.7 ± 16.1, 58.3–113.0	< 0.001
Upper limb RMT (%-MSO)	26.0 ± 4.4, 18.0–36.0	45.4 ± 12.2, 29.0–71.0	< 0.001
(V/m)	81.1 ± 13.0, 61.0–103.0	103.6 ± 23.6, 62.0–152.0	0.001
Lower limb RMT (%-MSO)	41.5 ± 7.6, 27.0–60.0	59.2 ± 13.9, 37.0–84.0	< 0.001

Significant differences are reported according to the Mann–Whitney U test for independent samples
