A secondary purpose was to determine the relationship between measures of articular disease severity and peak isometric knee extensor torque. Peak torque was measured with a computerized dynamometer. Twenty\u2010eight children with JRA and 28 children without JRAwere matched for age, sex, and body surface area. Peak isometric knee extensor torque was significantly lower among the children with JRA than their respective control (P &lt; 0.05, paired Student's t\u2010test, one\u2010tailed). There was no relationship between peak torque and measures ofarticular disease severity among the children with JRA. Subjects complained of quadriceps muscle discomfort as a result of the isometric muscle test. One child with JRA complained of increased knee pain and swelling. Peak isometric knee extensor torque appears to be a useful variable for characterizing muscle function deficits in children with JRA. Isometric muscle performance did not correlate with articular disease severity. The results suggest that isometric strengthening programs are indicated for this patient population. We recommend that clinicians monitor patients for joint and muscle symptoms during exercise training sessions.<\/jats:p>","DOI":"10.1002\/art.1790060207","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T01:07:24Z","timestamp":1171501644000},"page":"82-88","source":"Crossref","is-referenced-by-count":26,"title":["Comparison of peak isometric knee extensor torque in children with and without juvenile rheumatoid arthritis"],"prefix":"10.1002","volume":"6","author":[{"given":"Manuela Jasso","family":"Giannini","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth J.","family":"Protas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,12,8]]},"reference":[{"key":"e_1_2_1_2_2","volume-title":"Juvenile Rheumatoid Arthritis","author":"Brewer EJ","year":"1982"},{"key":"e_1_2_1_3_2","first-page":"116","volume-title":"Textbook of Pediatric Rheumatology","author":"Cassidy JT","year":"1982"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(70)80001-4"},{"key":"e_1_2_1_5_2","first-page":"47","volume-title":"Measurement in Physical Therapy","author":"Lamb RL","year":"1985"},{"key":"e_1_2_1_6_2","first-page":"218","article-title":"Reliability of quantitative strength measurements in children","volume":"60","author":"Molnar GE","year":"1979","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.1988.9.10.345"},{"key":"e_1_2_1_8_2","first-page":"195","article-title":"Current proposed revision of JRA criteria","volume":"20","author":"Brewer EJ","year":"1977","journal-title":"Arthritis Rheum"},{"key":"e_1_2_1_9_2","first-page":"109","article-title":"Standard methodology for Segment I, II, and III Pediatric Rheumatology Collaborative Study Group studies.
