It is associated with normal cerebrospinal fluid (CSF) pressure and ventricular dilation that cannot be attributed to cerebral atrophy. Objectives: To evaluate gait characteristics in patients with idiopathic NPH and investigate the effect of the CSF tap test (CSF-TT) on gait. Methods: Twenty-five patients diagnosed with probable idiopathic NPH were submitted to the CSF-TT. The procedure aimed to achieve changes in gait parameters. Results: Fifteen gait parameters were assessed before and after the CSF-TT. Five showed a statistically significant improvement (p &lt; 0.05): walking speed (p &lt; 0.001), cadence (p &lt; 0.001), step length (p &lt; 0.001), en bloc turning (p = 0.001), and step height (p = 0.004). Conclusion: This study demonstrated that gait speed was the most responsive parameter to the CSF-TT, followed by cadence, step length, en bloc turning, and step height.<\/jats:p>","DOI":"10.1590\/0004-282x20180037","type":"journal-article","created":{"date-parts":[[2018,6,9]],"date-time":"2018-06-09T19:03:07Z","timestamp":1528570987000},"page":"324-331","source":"Crossref","is-referenced-by-count":36,"title":["Gait
