Summary

Feasibility, acceptability, and preliminary efficacy of combined transcranial direct current stimulation and mindfulness for pain after total knee arthroplasty

Conditions

  • Osteoarthritis, Knee

Interventions

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 for 5 times 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 for 5 times by a recorded meditation.

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.
