The iNPH Radscale May Better Predict Whether Ventriculoperitonal Shunting was Offered, Compared to Drain Trial Gait Variables (P1-5.022)

Idiopathic normal pressure hydrocephalus (iNPH), can be treated surgically with ventriculoperitoneal shunting (VPS); however, there is no standardized way to evaluate VPS candidacy. Though physicians may consider the iNPH Radscale when screening patients for drain trials, the decision to offer a VPS is based on physician judgement of gait improvement in pre/post drain trial gait tests. For this study, we determined which Radscale and gait variables best predicted whether patients were offered VPS.
