Association of pain with frequency and magnitude of knee loading in knee osteoarthritis

OBJECTIVE: Although the relationship between pain and the magnitude of medial knee loading has been previously studied, the contribution of frequency of loading has not. The objective of this study was to determine whether the addition of loading frequency (steps/day) to loading magnitude (knee adduction moment [KAM] impulse) helps explain variance in knee pain in people with knee osteoarthritis (OA). METHODS: Participants were adults with …
