To assess conditioned pain modulation efficiency in persons with and without migraine headaches. ⋯ Migraine sufferers exhibited impaired conditioned pain modulation of the nociceptive blink reflex, suggesting a deficiency in inhibition of trigeminal nociception, which may contribute to the development of migraine headaches.

First, to determine the number of accident-related complex regional pain syndrome (CRPS) cases from 2008 to 2015 and to identify factors associated with an increased risk for developing CRPS. Second, to analyze the duration of work incapacity and direct health care costs over follow-up periods of two and five years, respectively. ⋯ CRPS is a relatively rare condition but is associated with high direct health care costs and work incapacity.

The hypoalgesic effects of exercise are well described, but there are conflicting findings for different modalities of pain; in particular for mechanical vs thermal noxious stimuli, which are the most commonly used in studies of exercise-induced hypoalgesia. The aims of this study were 1) to investigate the effect of aerobic exercise on pressure and heat pain thresholds that were well equated with regard to their temporal and spatial profile and 2) to identify whether changes in the excitability of nociceptive pathways-measured using laser-evoked potentials-accompany exercise-induced hypoalgesia. ⋯ This is the first investigation to compare the effects of exercise on pressure and heat pain using the same stimulation site and pattern. The results show that aerobic exercise reduces mechanical pain sensitivity more than thermal pain sensitivity.

It has been estimated that 20% of the general population will suffer shoulder pain throughout their lives, with a prevalence that can reach up to 50%. The suprascapular nerve (SSN) provides sensation for the posterior and superior regions of the glenohumeral joint, whereas the anterior and inferior zones and the skin are innervated mostly by the axillary nerve. Pulsed radiofrequency on the SSN has been proposed as a therapeutic option in chronic shoulder pain. Axillary nerve block has been proposed in the context of surgical analgesia as an adjuvant to SSN block. ⋯ By adapting an approach developed in acute pain management, we can safely deliver pulsed radiofrequency to the suprascapular and axillary nerves for the treatment of shoulder pain.
