Post Operative Pain, Transcranial Direct Current Stimulation
Conditions
Brief summary
Transcranial direct current stimulation (tDCS) is a technique of noninvasive cortical stimulation allowing significant modification of brain function used. Clinical application of this technique could be helpful for pain, Parkinson's disease, dystonia, cerebral palsy and dementia etc. And tDCS is safe with only mild, transient adverse effects. But there is few studies focused to postoperative states. The aim of this project is to reveal the effect of tDCS for postoperative pain after total knee replacement surgery,
Interventions
Intensity 2mA, 20minues, 4 times (post operation in 30min, in 4hrs, next day morning and next day afternoon) anodal tDCS applied over the left DLPFC cathodal tDCS applied over the right DLPFC
Intensity 0mA, 40 seconds, 4 times (post operation in 30min, in 4hrs, next day morning and next day afternoon) anodal tDCS applied over the left DLPFC cathodal tDCS applied over the right DLPFC
