  • Satisfaction with care

    4 weeks after randomization

Study Arms (4)

tDCS real + TENS real

ACTIVE COMPARATOR

Real transcranial direct current stimulation associated with real transcutaneous electrical nerve stimulation (TENS). tDCS: 20 minutes, 2mA, primary motor cortex anode (contralateral to the lesion) and supraorbital cathode (ipsilateral to the lesion). TENS: 40 minutes, 100Hz, 200µs, 2 channels with electrodes over the low back area of pain.

Procedure: Transcranial direct current stimulation (tDCS)Procedure: Transcutaneous electrical nerve stimulation (TENS)

tDCS real + TENS sham

EXPERIMENTAL

Real transcranial direct current stimulation associated with sham transcutaneous electrical nerve stimulation (TENS). tDCS: 20 minutes, 2mA, primary motor cortex anode (contralateral to the lesion) and supraorbital cathode (ipsilateral to the lesion). TENS: 40 minutes (30 seconds ON), 100Hz, 200µs, 2 channels with electrodes over the low back area of pain.

SHAM COMPARATOR

TENS: 40 minutes (30 seconds ON), 100Hz, 200µs, 2 channels with electrodes over the low back area of pain.

Procedure: Transcranial direct current stimulation (tDCS)Procedure: Transcutaneous electrical nerve stimulation (TENS)

Interventions

Technique based on the application of weak, direct electrical current to the brain through relatively large electrodes that are placed over the scalp, in which anodal and cathodal stimulation increases and decreases cortical excitability, respectively
