- Registration Number
- NCT05311956
- Lead Sponsor
- Weill Medical College of Cornell University
- Brief Summary
This is a 4-year project to see if a small battery-powered, device attached to a headband, that sits on the skin surface and delivers what is a hardly noticeable level of electrical stimulation can reduce pain in patients who receive hemodialysis on an ongoing basis.
- Detailed Description
This is a 4-year R01 project to conduct a randomized controlled trial to evaluate the efficacy of an at-home transcranial direct current stimulation (tDCS) device to mitigate pain in persons receiving hemodialysis (HD) on account of end-stage kidney disease (ESKD). Pain is a highly common and morbid condition among persons with ESKD requiring HD. Because the current method of managing pain in this population typically involves the use of analgesic medications that confer substantial health risks, novel non-drug therapies are needed to reduce pain and lessen reliance on opioid and other drug therapies. The investigators will undertake a randomized controlled trial to determine the efficacy of an at-home neuromodulatory device to mitigate pain and improve other salient outcomes (e.g., mood, quality of life) in a stratified sample of Hispanic or Latino(a), Black or African American, and non-Hispanic White ESKD patients requiring HD. However, no individuals will be excluded based on race/ethnicity

Group Intervention Description Sham Comparator Sham tDCS Sham treatment will consist of 30 seconds of the direct current at 2mA and 0 current for the remaining time of the 20-minute application 5 times per week over eight consecutive weeks (40 applications in total). Experimental Active tDCS Patients will receive tDCS delivered over the motor cortex, at an intensity of 2mA, delivered for 20 minutes 5 times each week over eight consecutive weeks (40 applications in total).
- Primary Outcome Measures
Name Time Method Change in worst pain intensity over past 7 days Baseline, 8 weeks (at the end of intervention) Pain intensity will be measured by one question from the PROMIS (Patient-Reported Outcomes Measurement Information System) Pain Intensity - Short Form 3a. This 3-item instrument assesses how much a person hurts. This question asks in the past 7 days, "How intense was your pain at its worst?" Respondents report their pain on a 5-point scale: 1=Had no pain, 2=Mild, 3=Moderate, 4=Severe, and 5=Very severe.
- Secondary Outcome Measures
Name Time Method Number of related adverse events Up to 26-weeks post-baseline Occurrence of the number of related side effects and adverse events will be compared between groups.
Change in worst pain intensity over past 7 days Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Pain intensity will be measured by one question from the PROMIS (Patient-Reported Outcomes Measurement Information System) Pain Intensity - Short Form 3a. This 3-item instrument assesses how much a person hurts. This question asks in the past 7 days, "How intense was your pain at its worst?" Respondents report their pain on a 5-point scale: 1=Had no pain, 2=Mild, 3=Moderate, 4=Severe, and 5=Very severe.
Change in self-report pain and pain-related medication use Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Participants will be asked what pain and pain related medications they are taking including the dose of each medication and how often they take them. A worksheet will be personalized to each participant to minimize the amount of recording that participants have to do in this phase of the study. The Y axis will list the medication (if taken more than once a day, each time point will have its own line) while the X axis will have the dates these data need to be collected. The participant will indicate how many pills they took in the table itself. The total dose of each pain and pain-related medication taken over the 5-day recording periods will be compared.
Change in Pain interference (PROMIS pain interference short form) Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Pain interference will be measured by PROMIS (Patient-Reported Outcomes Measurement Information System) Pain Interference - Short Form 6b. This 6-item instrument measures the self-reported impact of pain on a person's life and assesses the extent to which pain may interfere with engagement with social, cognitive, emotional, physical, and recreational activities over a 7-day recall period. Pain Interference also incorporates items problem sleep and enjoyment in life, though the item bank only contains one sleep item. Respondents report levels of pain interference on a 5-point scale: 1=Not at all, 2=A little bit, 3=Somewhat, 4=Quite a bit, and 5=Very much.
Satisfaction with the tDCS-TH device and procedure 8 weeks (at the end of intervention) Satisfaction with the tDCS-TH device and procedure is assessed using the tDCS User Survey that includes 8 statements describing various aspects of user's experience, such as education and training on tDCS use, ease of the procedure, or user's interest in future use of the device. on the first 7 statements are rated on a 5-point scale with anchor points Strongly Agree- Strongly Disagree. The last question is an open ended question asking about challenges and ways to improve
Change in Quality of Life Questionnaire Score (WHOQOL-BREF) Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Quality of Life will be measured by the Quality of Life Questionnaire (WHOQOL-BREF), a 26-item widely used and validated measure developed by the World Health Organization. Specific domains asked looking back over the last 2 weeks include physical health (e.g., enough energy for everyday life), psychological health (e.g., frequency of negative feelings), social relationships (e.g., satisfaction of support from friends), and environment (e.g., access to health services). Respondents answer each question on a 5-point scale and are transformed linearly to an overall adjusted score ranging from 0 to 100; with a higher score indicating higher quality of life.
Number of possibly related adverse events Up to 26-weeks post-baseline Occurrence of the number of possibly related side effects and adverse events will be compared between groups.
Change in average pain intensity over past 7 days (PROMIS pain intensity short form) Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Pain intensity will be measured by PROMIS (Patient-Reported Outcomes Measurement Information System) Pain Intensity - Short Form 3a. This 3-item instrument assesses how much a person hurts. The first two items assess pain intensity utilizing a 7-day recall period (items include the phrase "the past 7 days") while the last item asks patients to rate their pain intensity "right now." Respondents report their pain on a 5-point scale: 1=Had no pain, 2=Mild, 3=Moderate, 4=Severe, and 5=Very severe.
Change in Depressive Symptoms (Patient Health Questionnaire; PHQ-8) Baseline, 2 weeks (during intervention), 8 weeks (at the end of intervention), 12, 16, and 26 weeks post-baseline. Depressive Symptoms will be measured by PHQ-8 (Patient Health Questionnaire). This 8-item instruments measures symptoms of depression over the past 2 weeks such as, 'feeling down, depressed, or hopeless' or 'poor appetite or overeating'. Respondents report level of depression symptoms on a 4-point scale: 0=not at all, 1=Several days, 2=More than half the days, and 3=Nearly every day. The overall score range is 0 to 24 with a higher score indicating higher depressive symptoms.
Number of probably related adverse events Up to 26-weeks post-baseline Occurrence of the number of probably related side effects and adverse events will be compared between groups.
