Detailed Description
The project is to assess the preliminary feasibility, acceptability, and efficacy of self-administered preoperative tDCS+MBI in older adults (50+) undergoing TKR.
And to determine the effects of 5, 20-minute preoperative self-administered tDCS sessions combined with brief MBI on analgesic medication consumption following TKR.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: preoperative active tDCS+MBI
Active tDCS with simultaneous meditation intervention will be applied.
|
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.
|
Sham Comparator: preoperative sham tDCS+MBI
Sham tDCS with simultaneous sham MBM intervention will be delivered.
|
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Analgesic consumption
Time Frame: day 3 after surgery
|
The dose of every opioid received within 3 days postoperatively will be transcribed and converted into standardized parenteral morphine equivalents using the Centers for Disease and Control Prevention Guidelines on opioids.
A total in milligrams will be calculated for each day and means will be obtained for all groups.
|
day 3 after surgery
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
numerical rating scale (NRS)
Time Frame: day 3 after surgery
|
The NRS total score ranges from 0 (no pain) to 100 (most intense pain imaginable).
|
day 3 after surgery
|
Brief Pain Inventory (BPI)
Time Frame: day 3 after surgery
|
It includes seven items and evaluates the impact of pain on general activity, mood, walking, work, relationships, sleep, and enjoyment of life via a NRS (0-10).
Each item represents a subscale and can be scored and analyzed individually (0-10), with the anchors being "does not interfere" (0) and "completely interferes" (10).
A total interference score can also be calculated by taking the sum of all the items.
|
day 3 after surgery
|
Patient Health Questionnaire-4 (PHQ-4)
Time Frame: day 3 after surgery
|
with regards to emotional function, considering established relations between pain, anxiety, and depression, measures of anxiety and depression will be taken
|
day 3 after surgery
|
Pain Catastrophizing Scale (PCS)
Time Frame: day 3 after surgery
|
to assess patients' pain-related catastrophic thoughts.
It includes 13 items divided into three subscales: rumination (4 items), magnification (3 items), and helplessness (6 items).
Each item is rated on a 5-point scale with the end points not at all (score=0) and all the time (score=4).
|
day 3 after surgery
|
Change in pain related cortical response using a continuous wave, multichannel Functional near-infrared spectroscopy (fNIRS) imaging system
Time Frame: change from baseline at day 5 of intervention
|
Pain-related cortical response will be measured using a continuous-wave, multichannel fNIRS imaging system (LIGHTNIRS, Shimadzu, Kyoto, Japan) with three semiconductor lasers at 780, 805, and 830 nm.
Optical recordings will be collected during thermal pain stimulation.
|
change from baseline at day 5 of intervention
|
Change in descending pain modulation (CPM) as measured by the quantitative sensory testing
Time Frame: change from baseline at day 5 of intervention
|
Descending pain modulation will be determined by the change in pressure pain threshold on the trapezius immediately after the immersion of the contralateral hand up to the wrist in a cold water bath at 12°C for one minute, with higher CPM scores indicating better descending pain modulation.
Descending pain modulation will be reflected by an increase in pressure pain threshold after cold water immersion.
