This study evaluated the biomechanical performance and range of motion (ROM) restriction of a semi-custom 3D-printed brace (3DP) compared with two traditional braces (Medi-H, Medi-S). Sixteen participants performed static standing, flexion, extension, and pick-up tasks while wearing each brace. Interface pressure was recorded across seven anatomical regions, and thoracic (C7\u2013T8) and lumbar (T8\u2013L3) ROM were assessed simultaneously using repeated-measures ANOVA. Results showed that 3DP and Medi-H provided significantly greater overall pressures than Medi-S. During flexion and pick-up tasks, 3DP delivered enhanced support to the middle lumbar region and erector spinae, whereas Medi-H concentrated greater pressure on the spine, particularly during extension. Thoracic and lumbar ROM were restricted comparably across all braces (20\u201330\u00b0). In conclusion, 3DP achieves an equivalent restriction of sagittal motion to traditional braces while offering superior regional support to the upper and middle lumbar regions.<\/jats:p>","DOI":"10.3390\/bioengineering13080910","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T09:11:36Z","timestamp":1786525896000},"page":"910","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating Interface Pressure Distribution and Range of Motion in a Mesh-Structure 3D-Printed Lumbar Brace"],"prefix":"10.3390","volume":"13","author":[{"given":"Hsiang-Chieh","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Physical Therapy and Assistive Technology, National Yang Ming Chiao Tung University, Taipei 112304, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Po-Yin","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy and Assistive Technology, National Yang Ming Chiao Tung University, Taipei 112304, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3351-7279","authenticated-orcid":false,"given":"Chen-Sheng","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy and Assistive Technology, National Yang Ming Chiao Tung University, Taipei 112304, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"E128","DOI":"10.1097\/BRS.0000000000005265","article-title":"Global, regional, and national burden of low back pain: Findings from the global burden of disease study 2021 and projections to 2050","volume":"50","author":"Cheng","year":"2025","journal-title":"Spine (Phila Pa 1976)"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e2165","DOI":"10.52225\/narra.v5i1.2165","article-title":"Impact of lumbar support on pain reduction in low back pain patients: A systematic review and meta-analysis of randomized control trials","volume":"5","author":"Akbar","year":"2025","journal-title":"Narra J."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1097\/JPO.0000000000000390","article-title":"The effect of rigid spinal orthosis on the muscular capacity of patients with low back pain\u2014A 3-month follow-up study","volume":"35","author":"Rimaud","year":"2023","journal-title":"J.
