Among adults with persistent post-amputation pain, increased amputated-region pain sensitivity may reflect peripheral sensitization or indicate underlying central sensitization. To determine whether underlying central sensitization may contribute to increased pain sensitivity in this population, this study compared clinical signs and symptoms associated with central sensitization between adults with post-amputation pain who demonstrate or lack increased amputated-region sensitivity (as compared to reference data). ⋯ Participants with increased amputated-region sensitivity demonstrate generalized, secondary-site pain hypersensitivity, potentially indicating underlying central sensitization. Central sensitization symptom scores, however, were similar between groups, suggesting differences in physiological pain sensitivity may not manifest in subjective post-amputation pain descriptions.

Chronic venous insufficiency (CVI) is a progressive and common disease that affects the superficial and deep venous systems of the lower limbs. CVI is characterised by valvular incompetence, reflux, venous obstruction or a combination of these symptoms, with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs. It places a large financial burden on health systems. There is a wide variety of treatment options for CVI, ranging from surgery and medication to compression and physiotherapy. Balneotherapy (treatments involving water) may be a relatively cheap and efficient way to deliver physiotherapy to people with CVI. This is an update of a review first published in 2019. ⋯ For the comparison balneotherapy versus no treatment, we identified moderate-certainty evidence that the intervention improves disease severity signs and symptoms scores slightly, low-certainty evidence that it improves pain and skin pigmentation changes, and very low-certainty evidence that it improves HRQoL. Balneotherapy compared with no treatment made little or no difference to adverse effects, oedema or incidence of leg ulcers. Evidence comparing balneotherapy with other interventions was very limited. To ensure adequate comparison between trials, future trials should standardise measurements of outcomes (e.g. disease severity signs and symptoms score, HRQoL, pain and oedema) and follow-up time points.

Virtual reality hypnosis (VRH) has emerged as a new and promising option for pain management. Nonetheless, neural dynamics of pain modulation during VRH have not been investigated yet. The aim of this study was to measure the effects of VRH on pain, combining neurophysiological and self-reported measurements. ⋯ VRH decreases experimental pain perception, increases subject level of dissociation and modulates cerebral pain processing mechanisms. Pain can be managed with analgesic medication but also through complementary interventions. Among these, hypnosis and virtual reality (VR) are known to reduce pain for patients and healthy individuals. In recent years, an innovative technique combining hypnosis and VR has been proposed to help patients in managing pain. However, to our knowledge, no study has focused on the underlying mechanisms of this VR/hypnosis combination. We showed that VR combined with hypnosis decreases experimental pain, increases dissociation and influences EEG modulation.

Randomized Controlled TrialClinical and electrophysiological efficacy of extracorporeal shock-wave therapy in carpal tunnel syndrome: a placebo-controlled, double-blind clinical trial.
The aim of this study was to evaluate the efficacy of radial extracorporeal shock wave therapy on pain, functionality, and electrophysiological measurements in carpal tunnel syndrome. ⋯ This study shows that radial extracorporeal shock wave therapy has positive effects on pain, functionality, and electrophysiological measurements for mild-to-moderate carpal tunnel syndrome 1 month after application.

A prospective study. ⋯ The SC-LSIQ features good internal consistency, reliability, and validity for evaluating Chinese patients with LBP. Results suggest that the SC-LSIQ can be appropriately applied to patients with LBP in routine clinical practice.
