Randomized Controlled Trial Multicenter Study
12-Month Results from Multicenter, Open-Label, Randomized Controlled Clinical Trial Comparing Differential Target Multiplexed Spinal Cord Stimulation and Traditional Spinal Cord Stimulation in Subjects with Chronic Intractable Back Pain and Leg Pain.
Spinal cord stimulation (SCS) is a well-established treatment for chronic intractable pain of the trunk and/or limbs; however, low back pain (LBP) is difficult to treat using traditional SCS. Differential Target Multiplexed spinal cord stimulation (DTM SCS) is an advanced approach inspired from animal studies demonstrating improved pain-related behavior and pain-relevant biological processes. ⋯ Superiority of DTM SCS compared with traditional SCS for chronic LBP was demonstrated. Clinical improvements provided by DTM SCS were sustained over 12 months and are expected to significantly impact the management of chronic LBP.

Randomized Controlled Trial Multicenter Study
Transcutaneous electrical acupoint stimulation before surgery reduces chronic pain after mastectomy: A randomized clinical trial.
Despite multiple interventions, the incidence of chronic pain after mastectomy could be as high as 50% after surgery. This study aimed to determine the efficacy of transcutaneous electrical acupoint stimulation (TEAS) before anesthesia induction in reducing chronic pain and to compare the effect of combined acupoint TEAS with that of single acupoint TEAS. ⋯ TEAS at combined acupoints before surgery was associated with reduced chronic pain 6 months after surgery.

Yoga, Eurythmy Therapy and Standard Physiotherapy (YES-Trial) for Patients with Chronic Non-specific Low Back Pain: a Three-Armed Randomized Controlled Trial.
We aimed to evaluate the effects of yoga and eurythmy therapy compared to conventional physiotherapy exercises in patients with chronic low back pain. In a three-armed, multicentre, randomized controlled trial, patients with chronic low back pain were treated for 8 weeks in group sessions (75 minutes once per week). Primary outcome was patients' physical disability (measured by RMDQ) from baseline to week 8. ⋯ Clinical Trials Register: DRKS-ID: DRKS00004651 Perspective: This article presents the results of a multicentre three-armed randomized controlled trial on the clinical effects of three 8-week programs in patients with chronic low back pain. Compared to the 'gold standard' of conventional physiotherapeutic exercises, eurythmy therapy and yoga therapy lead to comparable symptomatic improvements in patients with chronic low back pain. However, the within-group effect sizes were small to moderate and did not reach clinical meaningfulness on patients' physical disability (RMDQ).

Targeted Drug Delivery for Chronic Nonmalignant Pain: Longitudinal Data From the Product Surveillance Registry.
To assist in assessment of therapy risks and benefits of targeted drug delivery (TDD) for chronic nonmalignant pain using registry data on product performance, adverse events, and elective device replacement. ⋯ Treating chronic pain with escalating doses of strong systemic opioids often leads to inconsistent pain control, impaired function, untenable side effects, and reduced quality of life and this practice has contributed to the current opioid crisis in the United States. TDD has been an available therapy for these patients for greater than 30 years, and data from this real-world registry offer supporting evidence to the long-term safety of this therapy as an alternative to systemic opioids, as well as insights into patient acceptance and satisfaction.

Multicenter Study Observational Study
Persistent Incisional Pain after Noncardiac Surgery: An International Prospective Cohort Study.
The purpose of this study was to determine the incidence, characteristics, impact, and risk factors associated with persistent incisional pain. The hypothesis was that patient demographics and perioperative interventions are associated with persistent pain. ⋯ Persistent incisional pain is a common complication of inpatient noncardiac surgery, occurring in approximately 1 in 30 adults. It results in significant morbidity, interferes with daily living, and is associated with persistent analgesic consumption. Certain demographics, ethnicities, and perioperative practices are associated with increased risk of persistent pain.
