Isometric muscle performance did not correlate with articular disease severity. Peak isometric knee extensor torque appears to be a useful variable for characterizing muscle function deficits in children with JRA. One child with JRA complained of increased knee pain and swelling. Subjects complained of quadriceps muscle discomfort as a result of the isometric muscle test. There was no relationship between peak torque and measures ofarticular disease severity among the children with JRA. Peak isometric knee extensor torque was significantly lower among the children with JRA than their respective control (P < 0.05, paired Student's t‐test, one‐tailed). Twenty‐eight children with JRA and 28 children without JRAwere matched for age, sex, and body surface area. Peak torque was measured with a computerized dynamometer. A secondary purpose was to determine the relationship between measures of articular disease severity and peak isometric knee extensor torque. N2 - This study compared peak isometric knee extensor torque in children with juvenile rheumatoid arthritis (JRA) and healthy children. T1 - Comparison of peak isometric knee extensor torque in children with and without juvenile rheumatoid arthritis We recommend that clinicians monitor patients for joint and muscle symptoms during exercise training sessions.", The results suggest that isometric strengthening programs are indicated for this patient population.
