Objective A systematic review designed to evaluate the benefits of remote group pain management for persons with chronic pain was performed. Methods PubMed, EMBASE and PsychINFO databases were searched in April 2019. Eligible studies evaluated teletherapy for chronic pain based on set inclusion and exclusion criteria. Two reviewers independently screened eligible studies, assessed risk of bias and extracted data. Each study design was rated and study quality was assessed using an 11-point scale of methodological quality. Results Comprehensive searches identified 12 studies that met all inclusion/exclusion criteria and each study was assessed for type of technology, study design, outcome measures, study findings and limitations. No published studies investigated synchronous teletherapy for groups of chronic pain patients. Methods of assessment varied considerably across studies. Strength of evidence was moderate and many of the selected studies had issues with treatment compliance/adherence and selection bias. Teletherapy strategies for persons with chronic pain were shown to improve pain, mood, disability and catastrophising, however half of the studies selected did not meet the criteria for acceptable standards for internal validity. Those trials with limited therapist involvement appeared to be less beneficial and tended to report lower adherence than those which had higher levels of therapist guidance or peer support. Conclusions Preliminary findings suggest that teletherapy and remote online cognitive behavioural therapy strategies can be effective in improving quality of life among persons with chronic pain, although the overall quality of evidence is moderate. Controlled trials are needed to assess live remote teletherapy for chronic pain.

Objective: This controlled trial examined the benefit of a high-frequency transcutaneous electrical nerve stimulation (hfTENS) device (the Quell, NeuroMetrix, Inc., Waltham, MA, U.S.A.) for patients with chronic low back pain (CLBP). Methods: Thirty-five (n = 35) participants were randomly assigned to use the device each day for 3 months (experimental group) and were compared with 33 subjects without the device (treatment-as-usual control group). All patients were instructed to complete baseline questionnaires and were assessed on thresholds of pressure pain and mechanical temporal summation as part of standardized quantitative sensory testing (QST). The subjects also uploaded smartphone applications (apps) for tracking use of the hfTENS and for daily pain assessment. Each participant completed weekly phone interviews, was prompted to complete daily pain app assessments, and was asked to repeat the baseline questionnaires again after 6 weeks and 3 months. Results: Sixty percent of the subjects were female, 77.9% were Caucasian, and the average age was 46.2 years. Significant reductions in pain intensity (P < 0.01) and activity interference (P < 0.025) and significant improvements in pain catastrophizing (P < 0.025) were noted in the experimental group compared with the control group. No group differences were found on depression, anxiety, or pain-related disability. Older subjects with a longer duration of pain tended to use the hfTENS more often. Subjects who showed greater sensitivity based on QST results revealed increased use of the hfTENS (P < 0.025) and tended to believe that the hfTENS was more helpful in reducing their back pain, but these findings did not reach significance (P = 0.09). Conclusion: These results suggest that hfTENS can have a moderate effect in reducing pain and improving quality of life in low back pain patients. Further trials designed to determine the mechanism of action of the hfTENS are needed. &

Complementary medicine therapies are frequently used to treat pain conditions such as headaches and neck, back, and joint pain. Chronic pain, described as pain lasting longer than 3-6 months, can be a debilitating condition that has a significant socioeconomic impact. Pharmacologic approaches are often used for alleviating chronic pain, but recently there has been a reluctance to prescribe opioids for chronic noncancer pain because of concerns about tolerance, dependence, and addiction. As a result, there has been increased interest in integrative medicine strategies to help manage pain and to reduce reliance on prescription opioids to manage pain. This article offers a brief critical review of integrative medical therapies used to treat chronic pain, including nutritional supplements, yoga, relaxation, tai chi, massage, spinal manipulation, and acupuncture. The goal of this article is to identify those treatments that show evidence of efficacy and to identify gaps in the literature where additional studies and controlled trials are needed. An electronic search of the databases of PubMed, The Cochrane Library, EMBASE, PsycINFO, and Science Citation Index Expanded was conducted. Overall, weak positive evidence was found for yoga, relaxation, tai chi, massage, and manipulation. Strong evidence for acupuncture as a complementary treatment for chronic pain that has been shown to decrease the usage of opioids was found. Few studies were found in which integrative medicine approaches were used to address opioid misuse and abuse among chronic pain patients. Additional controlled trials to address the use of integrative medicine approaches in pain management are needed.
