Description
Summary:•Hypoalgesic effect of SWs intervention is only produced under moderate pain.•Greater hypoalgesic effect is also shown in the contralateral limb of application.•Descending inhibitory system activation needs to be deeply studied under SW-MP.•Further studies about SW application are necessary in patients with musculoskeletal conditions. To determine if the perceived pain intensity during the application of shock waves (SWs) is a determinant mechanism in producing hypoalgesic changes in pressure pain thresholds (PPTs) in asymptomatic individuals. A randomised, single-blind controlled trial [NCT03455933]. University. Sixty-three asymptomatic individuals. Participants were randomised into three groups: 1-SWs causing mild pain (SW-DP); 2-SWs generating moderate pain (SW-MP); and 3-cold pressor test (CPT). Before and after the intervention, the PPT was evaluated bilaterally at the following points: lateral epicondyle, median nerve in the flexure of the elbow, and tibia. The results showed differences between various groups over time for all PPTs assessments, due to the existence of statistically significant differences in the interaction group x times (dominant arm lateral epicondyle [P
