Impact of core stability exercises on bone mineralization and functional capacity in children with polyarticular juvenile idiopathic arthritis: a randomized clinical trial

Background Juvenile idiopathic arthritis (JIA) is the most prevalent rheumatic disease in children. The core stability exercises ensure proper muscular strength and balance around the lumbo-pelvic-hip complex .

Description
Summary:Background Juvenile idiopathic arthritis (JIA) is the most prevalent rheumatic disease in children. The core stability exercises ensure proper muscular strength and balance around the lumbo-pelvic-hip complex . Objective This study evaluated whether the use of core stability exercises would increase the effectiveness of conventional physical therapy (PT) in enhancing bone mineralization and improving functional capacity in children with polyarticular JIA. Methods Thirty-three children with polyarticular JIA (age; 10–14 years) assigned randomly into two groups: the control group ( n  = 16) received the conventional PT, and the study group ( n  = 17) received the core stability exercises in addition to the same conventional PT program. Both core stability and conventional PT exercises continued for 3 months. The measures of bone mineralization and functional ability were investigated by dual-energy X-ray absorptiometry (DXA) device and 6-min walk test (6MWT), respectively, at baseline and immediately post-treatment. Results Analysis of covariance (ANCOVA) revealed significant differences between groups in favor of the study group regarding measures of bone mineralization of lumbar spine and femoral neck regions as P   0.05. There was a significant difference between the two groups concerning functional capacity measured in 6MWT ( P
