Background Rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA), constitute the most frequent pathological states leading to the development of foot deformities, which reduce the quality of life and cause disability.
Objectives The aim of the present study was to compare the results of plantoconturographic examination, obtained by means of a computer podoscope, in OA and RA patients. Special attention was paid to the differences in the values of each parameter determining the level of foot function.
Methods The study was conducted on 94 female patients divided into two groups according to the type of disease. There were 54 patients with RA and 40 with OA. The control group consisted of 34 healthy women. The plantographic assessment of static foot structure was carried out by means of a device for computer-aided foot examination.
Results A fallen transverse arch of the right foot was statistically much more frequent in the RA patients than in OA patients or the control group. Significant differences in the values of the Wejsflog index were observed between RA patients and the control group. Similarly, there were statistically significant differences in the values of the hallux valgus angle (α) for the right foot between RA and OA patients vs. the control group, as well as between OA patients and the control group.
Conclusions Rheumatic diseases predispose patients to the disturbances of static foot function. The obtained results highlight the importance of diagnosing foot statics disorders in the prevention of destructive changes affecting the functioning of OA and RA patients.
