Accommodating Variable-Resistance Training in Patients With Juvenile Idiopathic Arthritis

"The training was conducted twice weekly for six successive weeks under the close supervision of a licensed pediatric physical therapist in accordance with the safety performance guidelines defined by the American Academy of Pediatrics and the US National Strength and Conditioning Association.~The training protocol included maximum voluntary concentric knee flexor/extensor actions. Three sets of five to 10 repetitions of maximum-effort concentric action at angular speeds of 240, 180, and 120 degrees/second.~The training started with a 10-minute warm-up exercise and ended up with a 5-minute cool-down exercise."

The program encompassed the standard exercises for patients with juvenile idiopathic arthritis (aerobic, weight-bearing, proprioceptive, flexibility, and strengthening exercises). The training was conducted for 45 minutes, two times a week for six successive weeks.
