This study evaluated the intra-rater reliability of GS and grip pressure (GP) using the Jamar dynamometer and a modified sphygmomanometer (ModSp) in patients with complex bilateral hand dysfunction. Secondary objectives included determining the correlation between the instruments and exploring patient preferences.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>Fifty-two individuals with severe bilateral hand dysfunction due to systemic sclerosis were assessed as a representative model. A standardized measurement protocol was followed for both instruments. Intra-rater reliability was analyzed using intraclass correlation coefficients (ICCs), and linear regression was used to derive conversion formulas. Patient preferences were recorded using standardized open-ended questions and analyzed via thematic content analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Both instruments demonstrated excellent ICCs (0.96\u20130.98). Strong positive correlations were found between instrument scores (r = 0.88\u20130.91,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001), and regression models explained 78\u201382% of the variance. However, Bland\u2013Altman analysis revealed systematic bias and relatively wide limits of agreement, indicating the methods are not interchangeable. Regarding preferences, 69.2% of participants favored the ModSp, citing greater comfort, better adaptation to deformities, and reduced pain during grasp, while 17.3% preferred the Jamar dynamometer and 13.5% reported no preference.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Jamar and ModSp devices demonstrated excellent intra-rater reliability for grip assessment in severe hand dysfunction. While strongly correlated, they are not directly interchangeable for precise monitoring. The ModSp offers a practical, patient-centered alternative when standard dynamometry is hindered by physical constraints.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17589983261472043","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T04:25:07Z","timestamp":1785212707000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Intra-rater reliability of grip strength measurements in severely restricted hands"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0360-1904","authenticated-orcid":false,"given":"\u00dcmit","family":"U\u011furlu","sequence":"first","affiliation":[{"name":"Department of Occupational Therapy, Faculty of Health Sciences, Bezmialem Vak\u0131f University, Istanbul, T\u00fcrkiye"},{"name":"Division of Rheumatology, Department of Internal Medicine, Cerrahpa\u015fa Faculty of Medicine, Istanbul University-Cerrahpa\u015fa, Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physio.2005.05.003"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.2174\/18743250-v16-e2201100"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/03080226231208409"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hansur.2022.02.007"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.4055\/cios21090"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1630.1999.00182.x"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2019.10.183"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.3390\/s24165100"},{"key":"e_1_3_7_10_2","first-page":"507","volume-title":"Scleroderma: From Pathogenesis to Comprehensive Management","author":"Avouac J","year":"2024","unstructured":"Avouac J, Buch MH, Allanore Y.
