Summary of recommendations for future research studies examining the relationship between physical activity and the risk for developing knee OA

Recommendation

Details


1

There is evidence to indicate the importance of investigating the role of the following factors when examining the relationship between physical activity and knee joint health: age, sex, body mass index and body composition, muscle strength, varus-valgus alignment and external knee adductor moment, and injury history

2

The measurement tool employed to assess knee OA must be valid, reliable and sensitive to change among healthy and OA populations

3

Instruments for the measurement of physical activity must be reliable and valid, and able to assess accurately the type, frequency, intensity and duration of activity


OA, osteoarthritis.
