Chronic low back (CLBP) pain is an important public health and socioeconomic problem worldwide and, despite the volume of research in the area, it remains a difficult condition to treat. The Neuromatrix pain model and new findings on the pain chronification process point to a greater efficacy of treatments that address central and peripheral rather than only peripheral structures. Transcranial direct current (tDCS) stimulation is a noninvasive neuromodulation technique that has been presenting recent advances in the treatment of chronic pain. However, when applied alone the magnitude of its effect is small in chronic musculoskeletal conditions such as chronic non-specific back pain. One option that could optimize the analgesic effect of tDCS would be the combination with therapeutic exercises, which play a central role in spinal rehabilitation programs as well as higher levels of evidence. The combination of these treatments (tDCS and exercise) may present an analgesic effect superior to the isolated interventions. This study aims to investigate the efficacy of tDCS combined with therapeutic exercises in people CLBP for pain relief, affective aspect of pain, disability, kinesiophobia and global perception. Sixty patients will be randomized into two distinct groups to receive either tDCS (anodal) + therapeutic exercises or tDCS (sham) + therapeutic exercises for 12 sessions over a four-week period. The primary clinical outcome (pain relief) and secondary outcomes (disability, affective aspect of pain, kinesiophobia, and perception of overall effect) will be collected before treatment and four weeks, three months and six months post randomization. The data will be collected by a blind examiner to the treatment allocation.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Anxiety | Visual analogue scale (VAS)for anxiety assesses anxiety symptoms that we tracked as possible confounding factor.
The VAS for general anxiety is assessed by a horizontal 100-mm-long line. The extreme left end points to no anxiety, and the extreme right end to the worst anxiety possible. |
4 weeks, 3 and 6 months after randomization | |
Other | Depression | Beck depression inventory (BDI) for depressive symptoms that we tracked as possible confounding factor.
The BDI is a tool of self-assessment of de- pression using a questionnaire with 21 items whose in- tensity varies from 0 to 3 (higher scores indicating more depressive symptoms). |
4 weeks, 3 and 6 months after randomization | |
Primary | Pain intensity | Pain intensity will be evaluated by numerical rating scale (0-10). | Four weeks after randomization | |
Secondary | Quality of pain | The Short form of the McGill pain questionnaire (SF-MPQ) consists of 15 representative words from the sensory and affective categories of the standard long form. The 6 point intensity scale and a VAS are included to provide indices of overall pain intensity. | 4 weeks, 3 and 6 months after randomization | |
Secondary | Disability | The Roland Morris disability questionnaire (RMDQ) is composed of 24 yes or no questions designed to assess disability related to back pain. | 4 weeks, 3 and 6 months after randomization | |
Secondary | Tampa Scale for Kinesiophobia | Irrational, and debilitating fear of movement and activity resulting from a feeling of vulnerability to painful injury or re-injury. Its a 17-item scale. | 4 weeks, 3 and 6 months after randomization | |
Secondary | Global perceived effect (GPE) | Global perceived effect is an 11 point scale that ranges from 5 (vastly worse) through 0 (no change) to 5 (completely recovered). For all measures of global perceived effect (at baseline and all follow-ups), participants were asked compared to when this episode ?rst started, how would you describe your back these days. A higher score indicates higher recovery from the condition. | 4 weeks, 3 and 6 months after randomization |
