To tackle issues such as long wait times and limited access to conventional care, telemedicine is emerging as a viable alternative. It offers benefits such as reduced travel and increased flexibility, with evidence showing comparable effectiveness to in-person care. However, usability remains a key challenge, impacting patient compliance.<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n In a 3-arm randomized controlled trial, our preplanned secondary analysis aimed to assess the usability and patient perceptions toward an autonomous app-based intervention (\u201cNOLA\u201d) for LBP to improve clinical practice of telemedicine interventions. Objectives included evaluating app usability, assessing perceptions toward telemedicine, and exploring app usage, adherence, and motivation.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Patients with LBP were recruited from May to August 2022 and randomized into App, Physio+App, or Physio groups. App and Physio+App groups were included in this subanalysis. Intervention duration was 6 weeks. Data on baseline characteristics, System Usability Scale, Telemedicine Perception Questionnaire, app usage, adherence, and motivation were collected via web-based questionnaires.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 64 participants were randomized to use the app with available data for 38 participants. The mean age of participants who completed was 49.9 (SD 13.6) years, with 78% (29\/38) experiencing LBP for more than 2 years. Usability scores (0\u2010100) were good (Physio+App: median 78, IQR 58-92, app: median 86, IQR 65-91). Positive telemedicine perceptions were noted, with 84% (15\/20) rating it an adequate addition to usual care. App usage varied, with 43% (16\/35) using it 3 to 5 days per week, and 64% (21\/33) reported motivation to use the app. The dropout rates (App: 14\/32, 44%; Physio+App: 12\/32, 38%; Physio: 11\/29, 38%) were similar, but participants who dropped out had statistically significantly less pain (completers: mean 3.9, SD 2.0; dropouts: mean 3.0, SD 2.0;\n P<\/jats:italic>\n =.02). Reasons for dropout were mostly not reported.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The app \u201cNOLA\u201d demonstrated good usability, and participants expressed positive perceptions toward telemedicine in those who completed the intervention. Despite concerns about the lack of physical contact, the majority considered telemedicine a convenient form of health care delivery. App usage and motivation were favorable, emphasizing the potential of app-based interventions in managing LBP.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/59866","type":"journal-article","created":{"date-parts":[[2025,8,25]],"date-time":"2025-08-25T20:12:43Z","timestamp":1756152763000},"page":"e59866-e59866","source":"Crossref","is-referenced-by-count":0,"title":["Usability and Acceptability of an App-Based Approach to Treat Low Back Pain: Preplanned Secondary Analysis of a Randomized Controlled Trial"],"prefix":"10.2196","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8794-3252","authenticated-orcid":false,"given":"Svenja","family":"Kaczorowski","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5863-5816","authenticated-orcid":false,"given":"Katharina","family":"Trompeter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4799-1191","authenticated-orcid":false,"given":"Carolin","family":"Kramer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8870-8457","authenticated-orcid":false,"given":"Christian","family":"Gr\u00fcneberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4507-8787","authenticated-orcid":false,"given":"Christian","family":"Thiel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6039-0141","authenticated-orcid":false,"given":"Lars","family":"Donath","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9307-832X","authenticated-orcid":false,"given":"Daniel L","family":"Belavy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,8,25]]},"reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1016\/S2665-9913(23)00098-X","article-title":"Global, regional, and national burden of low back pain, 1990\u20132020, its attributable risk factors, and projections to 2050: a systematic analysis of the global burden of disease study 2021","author":"GBD 2021 Low Back Pain Collaborators","journal-title":"Lancet Rheumatol"},{"issue":"2","key":"R2","doi-asserted-by":"publisher","first-page":"431","DOI":"10.1007\/s10926-020-09933-8","article-title":"Economic evaluation of an extended telehealth worksite exercise intervention to reduce lost work time from low back pain in career firefighters","volume":"31","author":"Dagenais","journal-title":"J Occup Rehabil"},{"issue":"6","key":"R3","doi-asserted-by":"publisher","first-page":"656","DOI":"10.1001\/jama.299.6.656","article-title":"Expenditures and health status among adults with back and neck problems","volume":"299","author":"Martin","journal-title":"JAMA"},{"issue":"2","key":"R4","doi-asserted-by":"publisher","first-page":"79","DOI":"10.1136\/bjsports-2018-099878","article-title":"What does best practice care for musculoskeletal pain look like?
