Abstract

The loading of knee joint is highly influential in progress of osteoarthritis, so there have been various studies on the dynamic loading of knee in different motions. Some have focused on the gait of people with OA. The proper method to measure and analyze people's gaits is to analyze gaits through synthetic and systematic data. After referring to a specialist, their height and weight were measured and they filled the WOMAC questionnaire. T-test was used to determine the difference between OA and healthy group. In order to determine the shape and discrepancy in the motion range, the three principles of PCA have been used. These principles represent the major changes which are used for analyzing the differences between groups. In this study, 10 healthy people and 16 patients were participated. The greatest differences between the healthy and OA group were observed in weight, BMI, and pace of walking, whereas there were no significant differences between their age, height and length of their steps (p d 0.05). OA group showed an increased range of motion in the static phase for both TTL and TTP (p < 0.05). The knee and hip torques demonstrated greater values in the OA group. Based on the results, it is not clear that these changes could improve the quality of life among these patients. However, there are some benefits. Despite the long-term effects of this gait are not clear, it seems that it might prevent excessive progress of OA.
