To design an adapted and effective muscle strengthening program, it is necessary to assess the muscle strength of muscle groups involved. The objective of this study was to assess the reliability and validity of measuring the maximum voluntary isometric strength of shoulder abductors, elbow flexors, and extensors using a handheld dynamometer.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Maximum voluntary isometric strength was measured using a handheld dynamometer, and the one repetition maximum test was performed using dumbbells. Three separate 24\u2010h measurement sessions were conducted: the first 2 sessions (Day 0 and Day 1) by a physiotherapist and the third session (Day 2) by another physiotherapist.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Fifty\u2010seven COPD patients (age: 65.7\u00a0\u00b1\u00a08.5; FEV1: 45.3\u00a0\u00b1\u00a018.9%) were included and 54 were analyzed across three measurement sessions. We found an excellent correlation for intra\u2010rater measurements (\n p<\/jats:italic>\n \u00a0<\u00a00.001; shoulder abductors:\n r<\/jats:italic>\n \u00a0=\u00a00.84, elbow flexors:\n r<\/jats:italic>\n \u00a0=\u00a00.94, elbow extensors:\n r<\/jats:italic>\n \u00a0=\u00a00.89) and good to excellent correlation for inter\u2010rater measurements (Day 0\/Day 2:\n p<\/jats:italic>\n \u00a0<\u00a00.01; shoulder abductors:\n r<\/jats:italic>\n \u00a0=\u00a00.76, elbow flexors:\n r<\/jats:italic>\n \u00a0=\u00a00.89, elbow extensors:\n r<\/jats:italic>\n \u00a0=\u00a00.87; Day 1\/Day 2: shoulder abductors:\n p<\/jats:italic>\n \u00a0<\u00a00.01;\n r<\/jats:italic>\n \u00a0=\u00a00.90, elbow flexors:\n r<\/jats:italic>\n \u00a0=\u00a00.91 elbow extensors:\n r<\/jats:italic>\n \u00a0=\u00a00.93). Poor to good concordances were observed between the maximum voluntary isometric strength and the one repetition maximum test for intra\u2010rater measurements.\n <\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n Handheld dynamometer is a reliable and valid tool for assessing upper limb muscle strength in clinical practice for COPD patients.<\/jats:p>\n <\/jats:sec>\n \n Trial Registration<\/jats:title>\n ClinicalTrials.gov Identifier: NCT04341753<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/pri.70111","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T17:45:12Z","timestamp":1758735912000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Reliability and Validity of Upper Limb Muscle Strength Measurements by Handheld Dynamometer in Patients With Chronic Obstructive Pulmonary Disease"],"prefix":"10.1002","volume":"30","author":[{"given":"Lo\u00efc","family":"P\u00e9ran","sequence":"first","affiliation":[{"name":"Pulmonary Rehabilitation Unit Morlaix Hospital Centre Morlaix France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne C\u00e9cile","family":"Berriet","sequence":"additional","affiliation":[{"name":"Pulmonary Rehabilitation Unit Morlaix Hospital Centre Morlaix France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine","family":"Le Ber","sequence":"additional","affiliation":[{"name":"Pulmonary Rehabilitation Unit Morlaix Hospital Centre Morlaix France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u00eblys","family":"Consigny","sequence":"additional","affiliation":[{"name":"INSERM CIC 1412 University Hospital of Brest Brest France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2354-349X","authenticated-orcid":false,"given":"Marc","family":"Beaumont","sequence":"additional","affiliation":[{"name":"Pulmonary Rehabilitation Unit Morlaix Hospital Centre Morlaix France"},{"name":"Univ Brest, Inserm CHRU Brest UMR 1304 (GETBO) Brest France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,24]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmr.2016.11.004"},{"key":"e_1_2_10_3_1","first-page":"132","article-title":"Determination of the Resistance Load for 1\u2010RM and 10\u2010RM","volume":"15","author":"Berger R.","year":"1961","journal-title":"Journal of the Association for Physical and Mental Rehabilitation"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140\u20106736(86)90837\u20108"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1183\/09059180.00005509"},{"key":"e_1_2_10_6_1","first-page":"1","article-title":"ASEP Procedures Recommendation I: Accurate Assessment of Muscular Strength and Power","volume":"4","author":"Brown L.","year":"2001","journal-title":"Journal of Exercise Physiology Online"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/ptj\/pzz059"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/s1350\u20104533(00)00024\u20102"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1053\/rmed.2000.0786"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0002\u20109149(99)80245\u20108"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40798\u2010020\u201000260\u2010z"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2007.07.011"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11\u20100475"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1589\/jpts.28.2238"},{"key":"e_1_2_10_15_1","first-page":"119","volume-title":"Physiological Assessment of Human Fitness","author":"Kraemer W.
