Quantitative sensory testing (QST) is a tool used to assess pain perception. People with OA demonstrate reduced pain thresholds to blunt pressure over affected joints and also at remote body sites, suggesting a contribution of central sensitization to OA pain [1]. Thresholds for thermally induced pain have been less intensively investigated in OA, perhaps because OA pain is … Show more
