Randomized Controlled Trial
H-Coil Repetitive Transcranial Magnetic Stimulation Relieves Pain and Symptoms of Anxiety and Depression in Patients With Chronic Peripheral Neuropathic Pain: A Randomized Sham-Controlled Crossover Study.
This study aimed to investigate the analgesic effects of H-coil repetitive transcranial magnetic stimulation (rTMS) primarily targeting the hand area of the primary motor cortex (M1) in patients with peripheral neuropathic pain. Given that the H-coil has a wider reach than conventional coils, there is a possibility that targeting the hand motor cortex also may stimulate prefrontal areas. Thus, we also aimed to examine whether rTMS with an M1 target could produce effects on psychologic outcomes. ⋯ The Clinicaltrials.gov registration number for the study is NCT05488808.

Improvements in Therapy Experience with Evoked Compound Action Potential Controlled, Closed-Loop Spinal Cord Stimulation - Primary Outcome of the ECHO-MAC Randomized Clinical Trial.
Spinal cord stimulation (SCS) is a well-established treatment for chronic neuropathic pain. However, over- or underdelivery of the SCS may occur because the spacing between the stimulating electrodes and the spinal cord is not fixed; spacing changes with motion and postural shifts may result in variable delivery of the SCS dose and, in turn, a suboptimal therapy experience for the patient. The evoked compound action potential (ECAP)-a measure of neural activation-may be used as a control signal to adapt SCS parameters in real time to compensate for this variability. ⋯ PERSPECTIVE: Patients with chronic pain need durable and dependable options for pain relief. SCS is an important therapy option, and new technology advancements could improve long-term therapy use. CL SCS offers a preferred and more consistent therapy experience for patients that could lead to increased therapy utilization and reliable therapy outcomes.

Mean of Daily Versus Single Week Recall-Based Pain Quality Assessments in Neuropathic Pain Trials: Implications for Assay Sensitivity.
Patients with neuropathic pain often present with variable pain and nonpainful sensory qualities that could serve as outcomes in randomized clinical trials (RCTs). This study aimed to investigate the within-participant variability in the severity of these sensory qualities and whether the means of 7 daily pain quality assessments provide better assay sensitivity (ie, more sensitivity to treatment effects) than single-week recall-based assessments. This secondary analysis used data from an RCT of transcutaneous electrical nerve stimulation for chemotherapy-induced peripheral neuropathy (N = 142). ⋯ Compared with single-week recall-based assessments of pain qualities, the mean of daily assessments may improve RCT assay sensitivity when used to define entry criteria and assess outcomes. PERSPECTIVE: This study suggests that means of daily pain quality assessments may improve assay sensitivity when used to define entry criteria and assess outcomes in clinical trials. This work may inform design of future clinical trials evaluating the intensity of different pain qualities.

Acupuncture modulation of chronic neuropathic pain and its association with brain functional properties.
Chronic neuropathic pain has been one of the prominent causes of disability, and acupuncture has shown promise in treatment. The present study aimed to characterize acupuncture modulation of chronic neuropathic pain and explore the related functional brain changes. Sixty chronic sciatica patients were divided into acupuncture- or sham acupuncture groups and received 10 sessions of treatment during 4 weeks. ⋯ Neurological indicators and clinical measurements could be used as potential predictors of acupuncture response. This study combines neuroimaging and artificial intelligence techniques to highlight the potential of acupuncture for the treatment of chronic neuropathic pain.

Efficacy of Mind-Regulating and Depression-Reliving Acupuncture in combination with Radiofrequency Thermocoagulation of Dorsal Root Ganglion for Post-herpetic Neuralgia.
This study is aimed at evaluating the efficacy of mind-regulating and depression-relieving acupuncture in combination with radiofrequency thermocoagulation of dorsal root ganglion (DRG) for post-herpetic neuralgia (PHN). ⋯ Compared with RFTC alone, acupuncture combined with RFTC of DRG has a better therapeutic effect for PHN.
