Summary

The purpose of this study is to assess the effects of tDCS in combination with TUS for the treatment of pain and functional limitations in subjects with NSCLBP. The investigators hypothesize that there will be a decrease in pain levels with active stimulation, when compared to sham stimulation.

Conditions

Interventions

DEVICE

transcranial Direct Current Stimulation (tDCS)

Subjects will receive 20 minutes of either active or sham tDCS at an intensity of 2 milliamps (mA). The anodal electrode will be placed over the primary motor cortex contralateral to the most painful side, and the cathodal electrode will be placed over the contralateral supraorbital area. In the sham group, the tDCS device will not be active for the full 20 minutes.

DEVICE

Transcranial Ultrasound (TUS)

Subjects will receive 20 minutes of either active or sham TUS. During active stimulation the ultrasound will be active for the full 20 minutes- however, during sham stimulation the ultrasound will not be active for the full 20 minutes.
