Assessing moderate-to-vigorous physical activity in hip and knee osteoarthritis using accelerometers: Implications of different patterns and cut-points for health and well-being.

Applying age-specific cut-points for MVPA assessment in older adults with lower limb OA had implications for MVPA associations with health and well-being when total volume, but not bouted, MVPA was considered. Age-specific total volume MVPA needs further understanding regarding patterns and affective responses it comprises. Bouted MVPA is an important pattern for MVPA accrual, but probably not an applicable PA target for many patients.
