Background: Gait disorders in patients with idiopathic normal pressure hydrocephalus (iNPH) share similar characteristics found in pathologies presenting with higher-level gait disorders that have been specifically associated with gait changes during walking while simultaneously performing an attention-demanding task (i.e. dual tasking). The current study assessed the effect of cerebrospinal fluid (CSF) tapping on quantitative gait modification during single and dual tasking in patients with a suspicion of iNPH.
Methods: Of 53 patients suspected of iNPH, 18 have been included in this study. Gait analysis during single- and dual-task condition (walking and backward counting) before and after tapping of 40 ml CSF has been performed.
Results: Gait speed (P < 0.01) and stride length (P < 0.05) were significantly improved during dual-task conditions after CSF tapping compared to the gait performance before spinal tapping, without such improvement for gait parameters during single-tasking.
Conclusion: Dual-tasking condition better reveals gait improvement after CSF tapping than single-tasking in patients suspected of iNPH.
