“…Over the last years, clinical studies targeting anodal M1 for pain control have had significant results. Different conditions have been considered as fibromyalgia [17,[48][49][50][51][52][53][54][55][56][57], neuropathic pain [58][59][60][61][62][63][64][65][66][67][68][69][70], migraine [71][72][73][74][75][76], low back pain (LBP) [77][78][79][80][81], musculoskeletal conditions [16,[82][83][84][85][86][87], myofascial pain syndrome [88,89], post-operative pain [90][91][92][93], among others (See Table 1).…”

Introduction: Transcranial Direct Current Stimulation (tDCS) is a non-invasive neuromodulation technique which has been widely studied for the treatment of chronic pain. It is considered a promising and safe alternative pain therapy. Different targets have been tested, each having their own particular mechanisms for modulating pain perception. Areas covered:We discuss the current state of the art of tDCS to manage pain and future strategies to optimize tDCS' effects. Current strategies include primary motor cortex tDCS, prefrontal tDCS and tDCS combined with behavioral interventions while future strategies, on the other hand, include high intensity tDCS, transcutaneous Spinal Direct Current Stimulation, cerebellar tDCS, home-based tDCS and tDCS with extended number of sessions.Expert commentary: It has been shown that the stimulation of the prefrontal and primary motor cortex is efficient for pain reduction while a few other new strategies, such as high intensity tDCS and network-based tDCS, are believed to induce strong neuroplastic effects, although the underlying neural mechanisms still need to be fully uncovered. Hence, conventional tDCS approaches demonstrated promising effects to manage pain and new strategies are under development to enhance tDCS effects and make this approach more easily available by using, for instance, home-based devices.

“…Recently, programs on smartphones have also been developed so that ABM can be used for self-training [24] . Shiasy et al reported the effect of combining ABM and transcranial direct current stimulation (tDCS) on chronic low back pain in 2020 [25] . The report indicated that five sessions of ABM and ABM + tDCS could reduce pain-related psychological consequences significantly, compared to the control and sham tDCS groups.…”

Effects of attentional bias modification on chronic low back pain in older outpatients

Objectives:In the present study, the effect of attentional bias modification (ABM) on older outpatients, with chronic low back pain, was examined.Design:This was a single-center, randomized, single-blinded, crossover trial and patients were randomly divided in a 1:1 allocation ratio into two groups: an ABM Leading group and an ABM Trailing group.Participants:Forty-three outpatients with chronic low back pain participated.Interventions:Patients were evaluated four times and the treatments were ABM + Normal intervention or Normal intervention only.Outcomes:Outcome measures included pain intensity on the Numerical Rating Scale, the Pain Catastrophizing Scale, Fear-Avoidance Beliefs Questionnaire, Hospital Anxiety and Depression Scale, Somatic Symptom Scale-8, and EuroQol 5 Dimension-3 levels questionnaire. In addition, we performed the 30-second Chair-Stand test and the Timed Up & Go test for physical function evaluations.Results:There was no change in pain intensity due to ABM. However, the total Pain Catastrophizing Scale score was significantly decreased, and the EuroQol 5 Dimension-3 levels questionnaire and 30-second chair-stand test were significantly improved (P <.05).Trial registration:The Health Science Ethics Committee, Graduate School of Biomedical Sciences, Nagasaki University (permit number: 17060861), and the clinical trial was registered with UMIN (UMIN000029424).

“…We included 64 studies (see Supplement 7 for citations) among 65 study reports (Figure 1). Notably, 6 studies (Bush et al., 1985; Kim et al., 2020; Lewis et al., 2010; Lichtbroun et al., 2001; Shiasy et al., 2020; Vlaeyen et al., 1996) were eligible for inclusion but failed to report the relevant outcomes sufficiently. We contacted the authors but received no response.…”

Background and ObjectiveContextual effects (e.g. patient expectations) may play a role in treatment effectiveness. This study aimed to estimate the magnitude of contextual effects for conservative, non‐pharmacological interventions for musculoskeletal pain conditions. A systematic review and meta‐analysis of randomized controlled trials (RCTs) that compared placebo conservative non‐pharmacological interventions to no treatment for musculoskeletal pain. The outcomes assessed included pain intensity, physical functioning, health‐related quality of life, global rating of change, depression, anxiety and sleep at immediate, short‐, medium‐ and/or long‐term follow‐up.Databases and Data TreatmentMEDLINE, EMBASE, CINAHL, Web of Science Core Collection, CENTRAL and SPORTDiscus were searched from inception to September 2021. Trial registry searches, backward and forward citation tracking and searches for prior systematic reviews were completed. The Cochrane risk of bias 2 tool was implemented.ResultsThe study included 64 RCTs (N = 4314) out of 8898 records. For pain intensity, a mean difference of (MD: −5.32, 95% confidence interval (CI): −7.20, −3.44, N = 57 studies with 74 outcomes, GRADE: very low) was estimated for placebo interventions. A small effect in favour of the placebo interventions for physical function was estimated (SMD: −0.22, 95% CI: −0.35, −0.09; N = 37 with 48 outcomes, GRADE: very low). Similar results were found for a broad range of patient‐reported outcomes. Meta‐regression analyses did not explain heterogeneity among analyses.ConclusionThe study found that the contextual effect of non‐pharmacological conservative interventions for musculoskeletal conditions is likely to be small. However, given the known effect sizes of recommended evidence‐based treatments for musculoskeletal conditions, it may still contribute an important component.SignificanceContextual effects of non‐pharmacological conservative interventions for musculoskeletal conditions are likely to be small for a broad range of patient‐reported outcomes (pain intensity, physical function, quality of life, global rating of change and depression). Contextual effects are unlikely, in isolation, to offer much clinical care. But these factors do have relevance in an overall treatment context as they provide almost 30% of the minimally clinically important difference.
