Randomized Controlled Trial
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.

Stress has a strong influence on pain sensitivity. However, the direction of this influence is unclear. Recent studies reported both decreased and increased pain sensitivities under stress, and one hypothesis is that interindividual differences account for these differences. The aim of our study was to investigate the effect of stress on individual pain sensitivity in a relatively large female sample. ⋯ These findings support the view that pain sensitivity under stress shows large interindividual variability, and point to a possible dichotomy of altered pain sensitivity under stress.

To examine the effects of noninvasive pulsed radio frequency energy (PRFE) on recurrent migraine headache associated with occipital neuralgia. ⋯ Improvement in frequency of headaches was noted, especially when PRFE was combined with GLONB. Further study is warranted.
