[39] | Evaluation was performed before, after the last day of intervention, after 2, 4 and 12Â weeks for follow-up. The evaluation methods included numeric rating scales (NRS) for pain intensity, interference with function, anxiety | The VR-tDCS intervention significantly reduced the intensity of neuropathic pain, more than the VR, tDCS and placebo interventions | Positive |
[40] | Evaluation was performed before and immediately after the intervention. Evaluation methods included: NRS for NP intensity, study of warm and heat pain threshold, recording of contact heatevoked potentials (CHEPs) to thermal stimulation, and NRS for CHEPs evoked pain perception | Two weeks of VR-tDCS induced significant changes in CHEPs, evoked pain and heat pain threshold in SCI patients with NP. Thirteen patients reported a mean decrease of 50% in the NRS for NP after VR-tDCS | Positive |
