We assessed the feasibility of this intervention by examining adverse events, patient satisfaction (measured on a Likert scale), usability (using the System Usability Scale, SUS), acceptability (evaluated through the Technology Acceptance Model questionnaire, TAM+), and pain onset (measured with the Numeric Rating Scale).

This study aims to use machine learning techniques and data collected from IMUs to assess the Fugl-Meyer upper extremity subscale for post-stroke patients with motor dysfunction. IMUs signals from 120 patients were collected during a clinical trial. These signals were fed into a gated recurrent unit network to complete the scoring of individual actions, which were then aggregated to obtain the total score.

Spasticity, anxiety, and depression remained unchanged.</p><p><strong>Conclusions: </strong>This study indicates that the hands-free Atalante exoskeleton is safe, feasible, and well-tolerated for gait and balance rehabilitation in post-stroke subjects, warranting larger randomized controlled trials to assess its efficacy.</p><p><strong>Trial registration: </strong>Evaluation of the Use of the Atalante Exoskeleton in Patients Presenting an Hemiplegia Due to Cerebrovascular Accident (INSPIRE) trial was registered at ClinicalTrials.gov (NCT04694001, registered on 20201231).</p>","PeriodicalId":16384,"journal":{"name":"Journal of NeuroEngineering and Rehabilitation","volume":"22 1","pages":"82"},"PeriodicalIF":5.2,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11992748/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143970423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
