Article	Evaluation method	Outcome	Effect
[39]	Evaluation was performed before, after the last day of intervention, after 2, 4 and 12 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
