AB0318 BAROPODOMETRIC COMPARISON OF PLANTAR PRESSURE IN KNEE OSTEOARTHRITIS PATIENTS AND RHUMATOID ARTHRITIS PATIENTS. (June 2019) - Fellous, Safaa
Abstract : Objectives: To compare the plantar pressure between patients with Knee Osteoarthritis and patients with rhumatoid arthritis Methods: This is a cross-sectional study, included 41 patients with rheumatoid arthritis (87.8% female, mean age 49 ± 11.9 [27-83] years, median duration of evolution was 9 (4.20)) months, and 40 knee osteoarthrosis patients (100% female, mean age 57.6 ± 5.2 [50-67] years, median evolution time was 36 (24, 69) months). The two groups were matched by BMI (27.5 vs. 29.6, p> 0.05). In the rheumatoid arthritis group: The mean DAS28 was 3.9 ± 1.3 [2-6] and the knee joint was affected in 22% of cases. In the knee osteoarthritis group: The knee osteoarthrosis was bilateral in 80% of the cases and the radiological severity (Stages 3 or 4 of Kellgren and Lawrence classification) was found in 27.5%. The baropodometric study was performed using a PRESSCAM® platform (SIDAS®, 38, 000 VOIRON, MEDICAPTEURS®). The static analysis was done in free position, for 30 seconds at 50 Hz with measure of plantar pressure parameters. Results: Conclusion: This comparative static baropodometric study of patients with RA and patients with knee osteoarthritis shows significant differences in bearing surface, which appears to be lower in the RA group, especially in the forefoot. The thrust on the forefoot is also less important in the RA group. these results could be explain by the rheumatoid forefoot, which decreased support and pressure on the forefoot.
