With a significantly higher Young\u2019s modulus than biological tissues, SMAs enable efficient and responsive interaction with the human body, making them well suited for musculoskeletal rehabilitation applications. This paper provides a comprehensive review of SMA-based wearable devices for both upper- and lower-limb rehabilitation. It explores their configurations, actuation mechanisms, associated challenges, and optimization strategies to enhance performance. By discussing recent advancements, this review aims to inform researchers and engineers on the development of sustainable, effective, and patient-centric wearable rehabilitation robots.<\/jats:p>","DOI":"10.3390\/bioengineering12030276","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T06:52:30Z","timestamp":1741675950000},"page":"276","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Wearable Soft Robots: Case Study of Using Shape Memory Alloys in Rehabilitation"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1055-4798","authenticated-orcid":false,"given":"Zain","family":"Shami","sequence":"first","affiliation":[{"name":"Institute of Micro and Nano Systems (IMNS), School of Engineering, The University of Edinburgh, Edinburgh EH9 3FF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tughrul","family":"Arslan","sequence":"additional","affiliation":[{"name":"Institute of Micro and Nano Systems (IMNS), School of Engineering, The University of Edinburgh, Edinburgh EH9 3FF, UK"},{"name":"Advanced Care Research Center, The University of Edinburgh, Edinburgh EH16 4UX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Lomax","sequence":"additional","affiliation":[{"name":"Institute of Micro and Nano Systems (IMNS), School of Engineering, The University of Edinburgh, Edinburgh EH9 3FF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2006","DOI":"10.1016\/S0140-6736(20)32340-0","article-title":"Global estimates of the need for rehabilitation based on the Global Burden of Disease study 2019: A systematic analysis for the Global Burden of Disease Study 2019","volume":"396","author":"Cieza","year":"2020","journal-title":"Lancet"},{"key":"ref_2","unstructured":"World Health Organization (2025, January 02).
