Stiffness was the predominant type of discomfort in most body parts. Numbness surpassed stiffness in the elbow and hand, whereas throbbing surpassed stiffness in the wrist. Body posture influenced upper arm and lower back discomfort, with a right-sided lying posture resulting in the highest level of lower back pain (p\u2009&lt;\u20090.05). Using a smartphone with a more flexed neck posture increased neck discomfort (p\u2009&lt;\u20090.05). Holding a smartphone with one hand, while controlling the screen with the opposite finger, increased hand pain (p\u2009&lt;\u20090.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The inferences obtained from this study indicate that smartphone usage posture significantly affects musculoskeletal discomfort. The suggested posture for minimizing musculoskeletal discomfort is to use the smartphone in a left-side-lying position, hold it vertically with both hands, and utilize both thumbs for texting and scrolling.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10538127241296339","type":"journal-article","created":{"date-parts":[[2025,2,11]],"date-time":"2025-02-11T03:11:11Z","timestamp":1739243471000},"page":"483-493","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison of musculoskeletal pain in neck, trunk, and upper limbs among Korean and Chinese smartphone users by posture: A cross-sectional survey"],"prefix":"10.1177","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7280-986X","authenticated-orcid":false,"given":"Yixin","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, The Graduate School, Yonsei University, Wonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ye-Jin","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, The Graduate School, Yonsei University, Wonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyeong-Ah","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, The Graduate School, Yonsei University, Wonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joo-Hee","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Health Science, Yonsei University, Wonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hye-Seon","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, The Graduate School, Yonsei University, Wonju, Republic of Korea"},{"name":"Department of Physical Therapy, College of Health Science, Yonsei University, Wonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,2,11]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"Ericsson [Internet].
