Table 4 Summary of recommendations for future research studies examining the relationship between physical activity and the risk for developing knee OA

From: Factors that may mediate the relationship between physical activity and the risk for developing knee osteoarthritis

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
  1. OA, osteoarthritis.
