Summary

This clinical trial aims to evaluate whether a 2 week regimen of transcranial direct current stimulation (tDCS) paired with mindfulness-based meditation (MBM) can improve pain modulation, reduce clinical pain, and alleviate osteoarthritis (OA)-related symptoms in patients with knee OA.

Conditions

  • Osteo Arthritis 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 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.

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 mA current for 30 seconds during each 20-minute session, conducted daily for 2 weeks. The meditation intervention will be applied simultaneously with tDCS for 20 minutes per session daily for 2 weeks by a recorded meditation.

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 sham MBM intervention will be delivered via a CD player that will look identical in both active and sham MBM.
