Therapeutic Ultrasound and Treadmill Training Suppress Peripheral Nerve Injury-Induced Pain in Rats.
Although evidence suggests that therapeutic ultrasound (TU) in combination with treadmill training (TT) suppresses nerve injury-associated pain, the molecular mechanisms for this action are not clear. ⋯ The combination of TU and TT reduces neuropathic pain more than either modality alone. This beneficial effect appears related to downregulation of proinflammatory IL-6 and Iba1, while upregulating the anti-inflammatory IL-10.

The anterior cingulate cortex (ACC) is a brain region that has been critically implicated in the processing of pain perception and modulation. While much evidence has pointed to an increased activity of the ACC under chronic pain states, less is known about whether pain can be alleviated by inhibiting ACC neuronal activity. ⋯ The findings of this study indicate that enhanced neuronal activity in the ACC contributes to maintain bone cancer-induced mechanical hypersensitivity and suggest that the ACC may serve as a potential therapeutic target for treating bone cancer pain.

The review aims to present the latest research into microglia and their role in pain. ⋯ Glial cells, composed of microglia, astrocytes, and oligodendrocytes, outnumber neurons in the central nervous system. The crosstalk between these cells and neurons is now established as participating in the development of chronic pain. There has been a great advance in the description of microglia reactivity from pro to anti-inflammatory phenotypes. The modulation of these phenotypes could be a potential target for pain therapy. Recently, different microglial reactivity between man and woman and between neonates and adults, in response to nerve injury were described, which could explain some of the sex differences in pain sensitivity and the absence of neuropathic pain development in neonates. Clinical trials using microglia as a target have been carried out in various neurological diseases and pain, with limited efficacy in the latter, but there are nonetheless, indications that with some improvement in study strategies microglia could be a future target for pain control.

ReviewPharmacological and non-pharmacological strategies in the integrated treatment of pain in neurorehabilitation. Evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation.
The interplay between pain and neurorehabilitation is very complex, in that pain may be a target for treatment, but can also have negative effects on neurorehabilitation procedures. Moreover, side effects of drugs, which are currently used to treat pain, may negatively influence rehabilitation outcomes. Because of the lack of guidelines or consensus, the Italian Consensus Conference on Pain in Neurorehabilitation (ICCPN) was aimed to answer some open questions on the treatment of pain in this setting. ⋯ Despite the lack of studies in patients undergoing neurorehabilitation, current guidelines on the pharmacological treatment of nociceptive and neuropathic pain may be applied in this setting. Non-pharmacological strategies include physical therapy, invasive procedures, psychological treatments and psychotherapy, which together with pharmacological therapies play a key role in the integrated approach to pain. The ICCPN recommendations offer information to ameliorate the current treatment of pain in neurorehabilitation, and to design future studies to answer the still open questions on this topic.

ReviewDiagnosing and assessing pain in neurorehabilitation: from translational research to the clinical setting. Evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation.
Pain is very common in neurorehabilitation, where it may be a target for treatment and have a negative effect on rehabilitation procedures and outcomes. Promising preliminary preclinical data support certain therapeutic approaches to pain, but there is a strong need of adequate preclinical models, experimental settings, outcome measures, and biomarkers that are more relevant for pain within the neurorehabilitation field. ⋯ The present ICCPN recommendations provide information on the relevance of current preclinical models, and may be helpful in ameliorating pain diagnosis and assessment, which are prerequisites for better application and tailoring of current pharmacological and non-pharmacological treatments. They may also be useful for future studies aimed at filling the gaps in the current knowledge of these topics.
