Este trabajo sugiere que la diferencia tiene raíces biológicas medibles en la sangre, aunque todavía es un estudio exploratorio con pocas personas. Para quien convive con ese dolor, abre la puerta a saber de antemano si una mejora simple le va a servir o si necesita otro camino.

We investigated whether circulating protein, transcriptional and autoantibody features were associated with variation in pain response to lifestyle interventions in people with knee OA. Methods: We performed an exploratory multi-modal analysis using participants from the INSPIRE randomised controlled trial and, for proteomic analyses, an independent WebEx cohort. Circulating inflammatory proteins were measured using Olink proximity extension assay at baseline and 6 weeks.
