Recent advances in artificial intelligence (AI) have enabled automated, marker-free analysis using two-dimensional photographs. This study evaluated the validity and reliability of MORA Vu, an AI-based posture estimation software, against radiographic parameters. Methods: A prospective pilot study was conducted with 72 participants, divided equally into the cervical and lower-limb alignment groups. Forward head posture (FHP) and digital hip\u2013knee\u2013ankle (DHKA) angles were measured using MORA Vu and compared with corresponding radiographic parameters. Three healthcare professionals independently conducted the AI-based assessments. Correlations were analyzed, and interrater reliability was assessed using the intraclass correlation coefficient (ICC). Results: FHP showed the strongest correlation with the craniovertebral angle (r = \u22120.712) and C2\u20137 sagittal vertical axis (r = 0.704). The DHKA angle strongly correlated with the radiographic hip\u2013knee\u2013ankle angle (r = 0.754). Interrater reliability demonstrated high agreement (ICC: 0.84 FHP, 0.90 DHKA). Conclusions: MORA Vu demonstrated strong validity and high reliability, supporting its potential as a noninvasive screening tool for postural assessment. Given its accessibility and radiation-free nature, it may serve as a viable alternative for routine postural evaluation.<\/jats:p>","DOI":"10.3390\/diagnostics15111340","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T03:34:46Z","timestamp":1748316886000},"page":"1340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Validity and Reliability of an Artificial Intelligence-Based Posture Estimation Software for Measuring Cervical and Lower-Limb Alignment Versus Radiographic Imaging"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9389-5429","authenticated-orcid":false,"given":"Sung Cheol","family":"Park","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Seoul Bumin Hospital, Seoul 07590, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanghee","family":"Lee","sequence":"additional","affiliation":[{"name":"EverEx, Seoul 06134, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jisoo","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Seoul Bumin Hospital, Seoul 07590, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2120-1111","authenticated-orcid":false,"given":"Chi-Hyun","family":"Choi","sequence":"additional","affiliation":[{"name":"EverEx, Seoul 06134, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chan","family":"Yoon","sequence":"additional","affiliation":[{"name":"EverEx, Seoul 06134, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Chan","family":"Ha","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Seoul Bumin Hospital, Seoul 07590, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,26]]},"reference":[{"key":"ref_1","first-page":"646","article-title":"Burden of major musculoskeletal conditions","volume":"81","author":"Woolf","year":"2003","journal-title":"Bull.
