Corey B. Simon, DPT, PhD, associate professor in Orthopaedic Surgery–Physical Therapy Division, and his research team recently published comments about movement-evoked pain (MEP), or pain that occurs with or is provoked by movement, is prevalent in individuals with knee osteoarthritis (KOA) and is associated with mobility impairment, clinical pain, and poor health outcomes (Butera et al., 2024). Recent studies and literature reviews show that MEP is distinguishable from pain-at-rest (PAR) and is driven by shared and distinct mechanisms, underscoring the importance of studying and assessing these constructs (Butera et al., 2024).
While the article's title states there are no relationships between MEP and PAR, the research team found it interesting that there were statistically significant correlations between performance on the 10 m walk test and MEP, as well as PAR and the MEP, recorded for the timed-up-and-go test and the 10 m walk test (Lozano-Meca et al., 2024).
