Methods: Two rounds of impairment ratings were performed by a team consisting of three physician experts and four premedical students, focusing on a comparison between the 2008 and 2024 editions of the AMA\u00a0Guides. The analysis included both the impairment values generated and the time taken to complete assessments with each version. Results: For the expert group, the mean duration required to complete an impairment rating was 5.0 min with the AMA Guides 2024, compared to 15.4 min using the AMA Guides 2008, with both editions achieving 100% accuracy and reliability. The premedical students demonstrated similar improvements, averaging 8.4 min per rating with the 2024 edition versus 26.4 min with the 2008 edition. The AMA Guides 2024 yielded enhanced accuracy, consistency, reliability, and reproducibility. Conclusions: The AMA\u00a0Guides Sixth Edition 2024 represents a significant advancement in impairment evaluation, particularly for spine and pelvis assessments. This updated edition introduces a more streamlined and time-efficient process while preserving the accuracy, consistency, and reproducibility essential to high-quality impairment ratings. By enhancing clarity and standardization, it sets a new standard in occupational health, offering a reliable framework that supports both clinical assessment and administrative oversight.<\/jats:p>","DOI":"10.3390\/jcm14082702","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T06:50:27Z","timestamp":1744699827000},"page":"2702","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reliability of the 2024 AMA Guides\u2019 Enhanced Methodology for Rating Spine and Pelvis Impairment"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2978-1907","authenticated-orcid":false,"given":"J.
