Purpose

The purpose of this study is to determine the effects of active transcranial direct current stimulation (tDCS) paired with active mindfulness-based meditation (MBM) on clinical pain,osteo arthritis (OA)-related clinical symptoms, physiopsychological pain processing and participant satisfaction with treatment in patients with knee OA.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
active tDCS paired with active MBM,
  • Device: active tDCS paired with active MBM
    Active tDCS with a constant current intensity of 2 milli ampere( mA)will be applied for 20 minutes per session daily for 2 weeks via the Soterix 1x1 tDCS mini-CT Stimulator device with headgear and saline-soaked surface sponge electrodes. The meditation intervention will be applied simultaneously with tDCS for 20 minutes per session daily for 2 weeks by a recorded meditation.
Active Comparator
sham tDCS paired with active MBM
  • Device: sham tDCS paired with active MBM
    For sham stimulation, the electrodes will be placed in the same positions as for active stimulation, but the stimulator will only deliver 2(milli ampere) mA current for 30 seconds. The meditation intervention will be applied simultaneously with tDCS for 20 minutes per session daily for 2 weeks by a recorded meditation.
Active Comparator
active tDCS paired with sham MBM
  • Device: active tDCS paired with sham MBM
    Active tDCS with a constant current intensity of 2 mA will be applied for 20 minutes per session daily for 2 weeks via the Soterix 1x1 tDCS mini-CT Stimulator device with headgear and saline-soaked surface sponge electrodes. The sham MBM intervention will be delivered via a CD player that will look identical in both active and sham MBM.
Sham Comparator
sham tDCS paired with sham MBM
  • Device: sham tDCS paired with sham MBM
    For sham stimulation, the electrodes will be placed in the same positions as for active stimulation, but the stimulator will only deliver 2 mA current for 30 seconds. The sham MBM intervention will be delivered via a CD player that will look identical in both active and sham MBM.
