    ObjectivesNoncancer chronic pain is a clinical challenge because pharmacological treatment often fails to relieve pain. Transcranial direct current stimulation (tDCS) is a treatment that could have the potential for pain relief and improvement in quality of life. However, there is a lack of clinical trials evaluating the effects of tDCS on the pain system. The aim of the present study was to evaluate the effect of 5 days of anodal tDCS treatment on the pain system in patients with chronic noncancer pain using quantitative sensory testing and quality of life questionnaires: (1) Brief Pain Inventory-short form, (2) European Organization for Research and Treatment of Life Questionnaire-C30, and (3) Hospital Anxiety Depression Scale.MethodsEleven patients with noncancer chronic pain (51 ± 13.6 y old, 5M) participated in the study. Anodal tDCS was applied for 5 consecutive days, followed by sham stimulation after a washout period of at least 2 weeks. Pressure pain thresholds and pain tolerance thresholds (PTT) were assessed in different body regions on days 1 and 5.ResultsAnodal tDCS appeared to maintain PTT at C5 (clavicle) on day 5, but sham stimulation decreased PTT ( P = 0.007). In addition, anodal tDCS increased PTT compared with sham at day 5 at Th10 ventral dermatomes ( P = 0.014). Both anodal and sham tDCS decreased the Brief Pain Inventory-short form total and interference scores, and the European Organization for Research and Treatment of Life Questionnaire-C30 fatigue score, but no interaction effect was observed.ConclusionThis study adds to the evidence in the literature that tDCS may be a potential therapeutic tool for the management of noncancer chronic pain.Copyright © 2024 Wolters Kluwer Health, Inc.
