AB0852-HPR Pedobagraphic measurements of rheumatoid feet and comparison with clinical parameters

Background Foot involvement in rheumatoid arthritis (RA) have been reported to be 56-100% in different studies. Pedobarography is used for dynamic plantar pressure measurement and to point out deformities of rheumatoid feet. Objectives The aim of this study was to assess the use of pedobarographic measurements for the investigation of the relationship between plantar pressure alterations and disease activity, radiological changes and foot indexes in patients with RA. Methods Patients over 18 years of age with rheumatoid arthritis experiencing foot pain were included. Data on patients sociodemographics, foot symptoms, anatomical distribution, intensity and duration of pain and access to podiatry services were collected using questionnaires completed during outpatient visit. For the functional status the scores of disease activity scale of 28 joints (DAS 28) and Health Assessment Questionnaire (HAQ) was used. Foot function index (FFI) and Manchester Foot Pain and Disability Index (MFPDI) were also administered to all RA patients. Modified Larsen scoring was used to asess radiological changes. Pedobarographic measurements was used to analyze foot loading characteristics. Results A total of 104 feet of 52 RA patients (48 female, 4 male) with a mean age of 53,88±11,36 years was evaluated. DAS 28 scores did not correlate with the plantar pressure changes (p>0,05). We found a significant correlation between HAQ scores and right medial midfoot loading pressure (r=0,355; p
