Non-malignant 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 chronic non-malignant pain patients using quantitative sensory testing (QST) and quality of life questionnaires: (1) Brief Pain Inventory-short form (BPI-sf), (2) European Organization for Research and Treatment of Life Questionnaire (EORTC-C30), and (3) Hospital Anxiety Depression Scale (HADS).
