Because it correlates with aerobic capacity, muscle strength, and functional status, the test can be used as a practical clinical measurement method to multidimensionally assess upper extremity performance. The 6-PBRT offers a simple, low-cost, and clinically practical alternative to laboratory-based upper extremity assessments, making it particularly suitable for routine clinical use in patients with RA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial registry<\/jats:title>\n                    <jats:p>Clinical Trials Registry Number: NCT06753851; Registration date: December 31 2024.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10538127261476803","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T15:20:04Z","timestamp":1787584804000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Validity and reliability of the six-minute pegboard and ring test for assessing upper limb functional capacity in patients with rheumatoid arthritis"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5346-8753","authenticated-orcid":false,"given":"Ba\u015fak","family":"Kavalc\u0131 Kol","sequence":"first","affiliation":[{"name":"Geothermal Resource Rehabilitation Application and Research Center, Pilot University Health Coordinatorship, K\u0131r\u015fehir Ahi Evran University, K\u0131r\u015fehir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8296-3158","authenticated-orcid":false,"given":"Merve","family":"F\u0131rat","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy and Rehabilitation, K\u0131r\u015fehir Ahi Evran University, K\u0131r\u015fehir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0886-2006","authenticated-orcid":false,"given":"Figen","family":"Tuncay","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Faculty of Medicine, K\u0131r\u015fehir Ahi Evran University, K\u0131r\u015fehir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9014-2106","authenticated-orcid":false,"given":"Ceren","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, Ayd\u0131n Atat\u00fcrk State Hospital, Ayd\u0131n, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,24]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kep253"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1191\/0269215504cr732oa"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.2340\/16501977-0619"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13075-015-0777-0"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.3233\/BMR-210056"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2005.02.006"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22102"},{"key":"e_1_3_3_9_2","first-page":"60","article-title":"Investigation of grip strength and upper extremity functional disability in patients with rheumatoid arthritis","volume":"3","author":"K\u0131n\u0131kl\u0131 GI","year":"2016","unstructured":"K\u0131n\u0131kl\u0131 GI, \u015eahin A, G\u00fcney H, et al.
