Abstract

Osteoarthritis (OA) is the most common type of Arthritis; mostly occur on knees and hip joint. Although majority of elderly suffer from OA, all the existing diagnosis methods have major drawbacks. Past studies have discovered the relationship between knee alignment and weight distribution which are directly related to the OA in the elderly and can be diagnosed years before occurrence of the OA. In this study, specially made Vibroarthrography (VAG) data logging tool was used to collect the knee vibrations of 20 subjects, where 10 of the subjects were confirmed OA patients with grade 2 and higher severity. The test was completed by placing the sensor mounted on knee band of both left and right knees. The goal of this research is to compare the left and right knee of both healthy and OA subjects using Vibroarthrography method. Current results obtained shows significant difference between left and right knee VAG signals for both Healthy and OA knees.
