Evaluating Improved Knee-Save device in Deep Squatting Tasks

Osteoarthritis (OA) is a chronic disease that affects 32.5 million people in the US. The prevalence of knee OA among adults over 60 years is approximately 10% (men) and 13% (women). Epidemiological studies showed that the prevalence of knee OA among workers is associated with their occupational activities. In many occupational activities, such as floor installation, electrical repairs and installations, roofing, retail stocking, gardening, and construction repairs, workers need to perform high knee-flexion tasks. Occupations involving high knee flexion tasks for at least 30 minutes per day resulted in increases in knee OA occurrence from 122% to 240 %, compared to average workers. The prevalence of OA will continue to increase with the aging workforce and the increasing life expectancy. Kn
