The aim of this study was to validate an in-house-developed gait analysis system (Striton), based on optical and inertial sensors and a novel method for stride detection, for measuring step-width during the swing phase of gait and temporal parameters. <jats:italic>Approach<\/jats:italic>: The step-width and stride-time measurements were validated in an experimental setup, against a 3D motion capture system and on an instrumented walkway. Further, test-retest and day-to-day variability were evaluated, and gait parameters were collected from 87 elderly persons (EP) and four individuals with idiopathic normal pressure hydrocephalus (iNPH) before\/after surgery. <jats:italic>Main results<\/jats:italic>: Accuracy of the step-width measurement was high: in the experimental setup mean error was 0.08 \u00b1 0.25 cm (R = 1.00) and against the 3D motion capture system 0.04 \u00b1 1.12 cm (R = 0.98). Test-retest and day-to-day measurements were equal within \u00b10.5 cm. Mean difference in stride time was \u22120.003 \u00b1 0.008 s between Striton and the instrumented walkway. The Striton system was successfully applied in the clinical setting on individuals with iNPH, which had larger step-width (6.88 cm, n = 4) compared to EP (5.22 cm, n = 87). <jats:italic>Significance<\/jats:italic>: We conclude that Striton is a valid, reliable and wearable system for quantitative assessment of step-width and temporal parameters during gait. Initial measurements indicate that the newly defined step-width parameter differs between EP and patients with iNPH and before\/after surgery. Thus, there is potential for clinical applicability in patients with reduced gait stability.<\/jats:p>","DOI":"10.1088\/1361-6579\/ab95ed","type":"journal-article","created":{"date-parts":[[2020,5,22]],"date-time":"2020-05-22T22:34:29Z","timestamp":1590186869000},"page":"065005","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Novel, clinically applicable method to measure step-width during the swing phase of gait"],"prefix":"10.1088","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7431-8335","authenticated-orcid":false,"given":"Tomas","family":"B\u00e4cklund","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fredrik","family":"\u00d6hberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gudrun","family":"Johansson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Grip","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3486-5251","authenticated-orcid":false,"given":"Nina","family":"Sundstr\u00f6m","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"pmeaab95edbib1","doi-asserted-by":"publisher","first-page":"265","DOI":"10.1016\/j.gaitpost.2017.03.021","article-title":"The high cost of swing leg circumduction during human walking","volume":"54","author":"Alex","year":"2017","journal-title":"Gait Posture"},{"key":"pmeaab95edbib2","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1186\/1743-0003-10-117","article-title":"Dual-task related gait changes after CSF tapping: a new way to identify idiopathic normal pressure hydrocephalus","volume":"10","author":"Allali","year":"2013","journal-title":"J.
