AB0308 FALL RISK EVALUATION WITH COMPUTERIZED DYNAMIC POSTUROGRAPHY IN RHEUMATOID ARTHRITIS PATIENTS

Background Patients with rheumatoid arthritis (RA) have a higher risk of falling due to pain and physiological/biomechanical deformities (decreased muscle density, decreased functional stability, changes in gait, etc.) [1]. Although high incidences falls been reported RA patients [1], there are not sufficient data regarding patient-specific fall risk. Objectives The aim this study was evaluate risk, via computerized dynamic posturography, patients, compare the results those age-matched healthy participants. Methods A total 29 (9 males, 20 females; mean age: 54.4±6.5 years) 18 participants (7 11 53.6±7.1) were included study. Detailed demographic, physical, medical characteristics recorded. Dynamic balance tested which assesses responses induced postural disruption [2]. translational ramp test (speed: 0.1 m/s), sinusoid tests (frequencies: 0.25 Hz - 0.50 Hz), limits stability evaluations applied. Ramp evaluated eyes open closed, antero-posterior direction, instructed keep their during tests. Limits on static platform, open. During test, told carry pressure center as far possible by performing movement only from ankle (in all directions), without lifting feet, trying fall. Results groups similar terms demographic physical (p>0.05). showed statistically significant alterations compared (p<0.05) (Table 1). positive 31% 5.6% control group (Figure Table 1.
