Do Weight-bearing versus Non-weight-bearing Pain Reflect Different Pain Mechanisms in Knee Osteoarthritis?: The Multicenter Osteoarthritis Study
https://acrabstracts.org/abstract/do-weight-bearing-versus-non-weight-bearing-pain-reflect-different-pain-mechanisms-in-knee-osteoarthritis-the-multicenter-osteoarthritis-study/
Jean Liew, John Farrar, Na Wang et. al.

Nov 9th, 2020 - Background/Purpose: Pain with weightbearing in knee OA is thought to be related to the activation of nociceptors; however, this is not considered the sole mechanism by which pain is experienced in OA as it would not explain the pain with non-weight-bearing that often occurs. Pain sensitization, reflecting altered pain processing, may contribute to pain at rest or while sleeping. The aim of this...
