A new observational study found that most people with knee osteoarthritis (OA) were able to walk the 6,000 daily steps they needed to improve their condition and prevent disability. They also were able to perform the sit-to-stand test (repeating five times) in a mean 10.2 seconds (taking longer than 12 seconds is associated with a fall risk in older adults). The researchers noted that knowing how much ability is necessary to be active will allow for more personalized intervention strategies to help OA patients increase their physical activity.
