Randomized Controlled Trial
Randomized Controlled Trial Comparing Landmark and Ultrasound-Guided Glossopharyngeal Nerve in Eagle Syndrome.
The glossopharyngeal nerve lies posterior to the internal carotid artery at the submandibular region. The primary objective of this study was to compare ultrasound-guided glossopharyngeal nerve block (UGPNB) and landmark glossopharyngeal nerve block (GPNB). ⋯ UGPNB with 1.5 mL of 0.5% ropivacaine and 20 mg of methylprednisolone injected posterior to the ICA in the submandibular region provides better pain relief for at least a week compared with an extraoral landmark technique when three weekly consecutive blocks are given. In most patients, a curvilinear probe and out-of-plane needle trajectory are most suitable for ultrasound block.

Morning Bright Light Treatment for Chronic Low Back Pain: Potential Impact on the Volatility of Pain, Mood, Function, and Sleep.
Most treatment outcome studies for people with chronic low back pain (CLBP) have based analyses on and reported only the mean levels of these factors. However, high levels of pain, mood, function, and sleep volatility may represent unique factors contributing to diminished quality of life. Our goal was to determine whether bright light treatment affected both mean levels of pain, mood, function, and sleep and reduced volatility in these outcomes. ⋯ Changes in mean levels and volatility were independent factors, suggesting that bright light treatment was related to participants experiencing fewer "pain flares." These findings underscore the potential importance of volatility as a future treatment target.

Although functional abdominal pain (FAP) is one of the most common pain problems in children, there is a lack of qualitative studies on this topic. Our aim was to increase knowledge in this field by testing an innovative written narrative methodology designed to approach the experiences of children with FAP and their parents. ⋯ A written narrative methodology was found to be a useful approach for understanding families' experiences. Results confirmed that FAP affects families at the emotional, behavioral, and social levels and that an online psychosocial intervention can help families.

Trigger points (TrPs) are hypersensitive spots within taut bands of skeletal muscles that elicit referred pain and motor changes. Among the variety of techniques used for treating TrPs, dry needling is one of the most commonly applied interventions. The question of eliciting local twitch responses (LTRs) during TrP dry needling is unclear. Our main aim was to investigate the evolution of the electromyographic (EMG) peak activity of each LTR elicited during dry needling into latent TrPs of the gastrocnemius medialis muscle. ⋯ We found that, in a series of LTRs elicited during the application of dry needling over latent TrPs in the medial gastrocnemius muscle, the RMS peak amplitude of each subsequent LTR decreased as compared with the initial RMS peak amplitude of previous LTRs. No changes in superficial EMG activity at rest were observed after dry needling of latent TrPs of the gastrocnemius medialis muscle.
