Neuropathic pain is a complex condition that can be refractory to conventional management and can cause persistent suffering in patients. Current pharmacologic treatments can provide temporary symptomatic relief; however, the mechanism of these therapies does not address the underlying cause of neuropathic pain. The use of injectable biologics for neuropathic pain has multiple proposed mechanisms for analgesia including attenuation of inflammatory mediated processes, arrest or delay of the degenerative process, inhibition of apoptotic pathways, and augmentation of the survival and recovery of injured and uninjured nerves. ⋯ According to the GRADE criteria, there is very low certainty of evidence in support of the efficacy of injectable biologics for treatment of neuropathic pain. Future efforts should focus on creating a standardized methodology and study design with respect to preparation, dosage and route of administration of biologics. This will serve as a catalyst for higher quality randomized trials with generation of more useful data to help drive informed clinical decision making.

Randomized Controlled Trial
Immediate Effects of Dry Needing or Manual Pressure Release of Upper Trapezius Trigger Points on Muscle Activity during the Cranio-Cervical Flexion Test in People with Chronic Neck Pain: A Randomized Clinical Trial.
To compare the effects of dry needling or manual pressure release on an active trigger point in the upper trapezius on craniocervical flexion test performance, pressure pain thresholds, and cervical range of motion in chronic neck pain. ⋯ A single session of dry needling or manual pressure release over upper trapezius active trigger points promotes limited effects on muscle performance during the craniocervical flexion test, pressure pain thresholds, and cervical range of motion in patients with chronic neck pain.

Randomized Controlled Trial
Predicting treatment response with sensory phenotyping in post-traumatic neuropathic pain.
Currently available treatments for neuropathic pain are only modestly efficacious when assessed in randomized clinical trials and work for only some patients in the clinic. Induced-pain or gain-of-function phenotypes have been shown to predict response to analgesics (vs placebos) in patients with neuropathic pain. However, the predictive value of these phenotypes has never been studied in post-traumatic neuropathic pain. ⋯ These data suggest that hyperalgesia, but not allodynia, predicts response to pregabalin in patients with chronic post-traumatic neuropathic pain. This study extends the growing data supporting the utility of induced-pain phenotypes to predict response to analgesics in post-traumatic neuropathic pain. Sensory phenotyping in large, multisite trials through the use of a structured clinical exam has the potential to accelerate the development of new analgesics and improve the generalizability of clinical trial results.

Chronic low back pain (CLBP) is among the most common types of pain in adults. Currently, injections and analgesic and nonsteroidal anti-inflammatory drugs are often provided for patients with CLBP. However, their effectiveness remains questionable, and the safest approach to CLBP remains debated. Meditation-based therapies constitute an alternative treatment with high potential for widespread availability. We evaluated the applicability of meditation-based therapies for CLBP management. ⋯ In conclusion, meditation-based therapies constitute a safe and effective alternative approach to CLBP management.

A heightened and organized understanding of sacral anatomy could potentially lead to a more effective and safe method of dorsal root ganglion stimulation (DRG-S) lead placement. The aim of this technical note is to describe a standardized access method for S1 DRG-S lead placement. ⋯ The described technique potentially improves the safety of S1 DRG-S lead placement. The parallel lead orientation to the DRG may also increase efficacy while lowering energy requirements.
