Fig. 4From: Gait apraxia evaluation in normal pressure hydrocephalus using inertial sensors. Clinical correlates, ventriculoperitoneal shunt outcomes, and tap-test predictive capacityRelative variations of instrumental variables between preTT and postVPS. Variations are normalized to the inter-subject standard deviation (SD) of each variable (Cohen’s effect size). Green = TUG, blue = 18mW. Non-significant changes are shown with pale coloursBack to article page
