DESIGN: Cross-sectional pilot study. SETTING: Outpatient multispecialty clinic. PARTICIPANTS: Participants with LSS and matched controls without LSS (n=10 per group; N=20). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Self-reported physical function (36-Item Short Form Health Survey [SF-36] physical functioning domain), Oswestry Disability Index, Swiss Spinal Stenosis Questionnaire, the Neurogenic Claudication Outcome Score, and inertia measurement unit (IMU)-derived temporospatial gait features. RESULTS: <.05). Compared with controls without LSS, patients with LSS have lower scores on physical capacity measures (median total distance traveled on 6-minute walk test: controls 505 m vs LSS 316 m; median total distance traveled on self-paced walking test: controls 718 m vs LSS 174 m). Observed differences in IMU-derived gait features, physical capacity measures, disability ratings, and neurogenic claudication scores between populations with and without LSS were statistically significant. CONCLUSIONS: Further evaluation of the association of IMU-derived temporospatial gait with self-reported physical function, pain related-disability, neurogenic claudication, and spinal stenosis symptom severity score in LSS would help clarify their role in tracking LSS outcomes.","journal":"Archives of Rehabilitation Research and Clinical Translation","year":2021,"id":204440,"datarank":0.24141568686511508,"base_score":1.6094379124341003,"endowment":1.6094379124341003,"self_citation_contribution":0.24141568686511508,"citation_network_contribution":0.0,"self_endowment_contribution":0.24141568686511508,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8982,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":716171,"name":"Salam Taraben","orcid":null,"position":1,"is_corresponding":false},{"id":730315,"name":"Christy Tomkins‐Lane","orcid":"0000-0002-0416-8965","position":2,"is_corresponding":false},{"id":786755,"name":"Wei Zhang","orcid":"0000-0002-6022-6832","position":3,"is_corresponding":false},{"id":730317,"name":"Amir Muaremi","orcid":"0000-0002-8227-4149","position":4,"is_corresponding":false},{"id":786756,"name":"Heike Leutheuser","orcid":"0000-0001-9931-2271","position":5,"is_corresponding":false},{"id":730316,"name":"Ruopeng Sun","orcid":"0000-0003-0738-3721","position":6,"is_corresponding":false},{"id":617896,"name":"Matthew Smuck","orcid":"0000-0002-2990-069X","position":7,"is_corresponding":false},{"id":617897,"name":"Charles A.
