A common outcome measure from clinical walking tests is average speed, which is reliable but does not capture important kinematical and temporal aspects of gait function. An extended gait analysis must be time efficient and reliable to be included in the clinical routine. The aim of this study was to add an inertial sensor system to a gait test battery and analyze the test-retest reliability of kinematic and temporal outcome measures. Measurements and analyses were performed in the hospital environment by physiotherapists using customized software. In total, 22 healthy persons performed comfortable gait, fast gait, and stair walking, with 12 inertial sensors attached to the feet, shank, thigh, pelvis, thorax, and arms. Each person participated in 2 test sessions, with about 3\u20136 days between the sessions. Kinematics were calculated based on a sensor fusion algorithm. Sagittal peak angles, sagittal range of motion, and stride frequency were derived. Intraclass-correlation coefficients were determined to analyze the test-retest reliability, which was good to excellent for comfortable and fast gait, with exceptions for hip, knee, and ankle peak angles during fast gait, which showed moderate reliability, and fast gait stride frequency, which showed poor reliability. In stair walking, all outcome measures except shoulder extension showed good to excellent reliability. Inertial sensors have the potential to improve the clinical evaluation of gait function in neurological patients, but this must be verified in patient groups.<\/jats:p>","DOI":"10.3390\/s22031171","type":"journal-article","created":{"date-parts":[[2022,2,6]],"date-time":"2022-02-06T20:40:18Z","timestamp":1644180018000},"page":"1171","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Test-Retest Reliability of Kinematic and Temporal Outcome Measures for Clinical Gait and Stair Walking Tests, Based on Wearable Inertial Sensors"],"prefix":"10.3390","volume":"22","author":[{"given":"Sofie","family":"Nilsson","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine and Department of Health, Medicine and Caring Sciences, Linkoping University, 581 83 Link\u00f6ping, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Per","family":"Ertzgaard","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine and Department of Health, Medicine and Caring Sciences, Linkoping University, 581 83 Link\u00f6ping, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8030-1051","authenticated-orcid":false,"given":"Mikael","family":"Lundgren","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, V\u00e4stervik Hospital, 593 33 V\u00e4stervik, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena","family":"Grip","sequence":"additional","affiliation":[{"name":"Department of Radiation Sciences, Biomedical Engineering, Ume\u00e5 University, 901 87 Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"The GBD 2016 Lifetime Risk of Stroke Collaborators, Feigin, V.L., Nguyen, G., Cercy, K., Johnson, C.O., Alam, T., Parmar, P.G., Abajobir, A.A., Abate, K.H., and Abd-Allah, F.
