POS1536-HPR THE RELATIONSHIP BETWEEN POSTURAL CHANGES AND TRUNK MUSCLE ENDURANCE IN CHILDREN WITH JUVENILE IDIOPATHIC ARTHRITIS

Background Body posture is defined as relative biomechanical alignment of body’s head, trunk, and extremities well position the body in space. might be altered due to different musculoskeletal pathologies. Juvenile Idiopathic Arthritis (JIA) a chronic inflammatory disease characterized by problems including bone muscle geometry alterations which may lead deteriorated posture. However, it not known whether trunk endurance associated with children JIA. Objectives To investigate relationship between postural changes Methods Thirty-four (eighteen female, sixteen male) were included study. Postural assessed three-dimensional evaluation system (PosturePrint System, Biotonix, Canada). The provides Posture Index (PI) score composite from three regions ribcage, pelvis. Higher PI scores indicate more Biering–Sørensen Test (BST), Flexor Endurance (FET), Lateral (LET) used assess endurance, Static Scapular (SSET) scapular endurance. Spearman Rank Correlation test was employed determine possible relationships. Results Enthesitis related arthritis most common JIA subtype study (38.2%) followed oligoarthritis (26.5%), polyarthritis (20.6%), systemic (14.7%). Significant negative correlations detected SSET PI-head (rho= -0.467, p=0.005), PI-ribcage -0.381, p=0.026); FET -0.469, p=0.005); LET -0.441, p=0.009). Table 1. Demographics, Variable Median (IQR 25 th /75 ) Age (years) 12.0 (10.0/14.0) Height (cm) 145.50 (140.00/158.25) Weight (kg) 42.75 (33.00/49.50) mass index (kg/m 2 19.17 (16.09/21.42) Biering– Sørensen (sec) 49.70 (28.42/80-78) 38.91 (30.59/60.19) 32.52 (19.99/59.68) 23.19 (15.93/44.74) Index-Head (score) 7.0 (5.0/8.0) Index-Ribcage 5.0 (4.0/6.0) Index-Pelvis 6.0 (3.0/8.0) IQR: Interquartile range Conclusion These results indicated that displacements head ribcage are linked decreased Exercise physical activity programs targeting result improvements these children.
