Experimental knee pain evoke spreading hyperalgesia and facilitated temporal summation of pain.
This study evaluated the deep-tissue pressure pain sensitivity and temporal summation of pain within and around healthy knees exposed to experimental pain. ⋯ The increased sensitivity and temporal summation found in this study were exclusive to deep -tissue with no contralateral decreased pain sensitivity. The study showed that acute knee joint pain leads to hyperalgesia and facilitated temporal summation in the infrapatellar fat pad and in muscles located distant to the injection site, in subjects with no history of knee pain.
