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.

Outcome Measures
Primary Outcomes (1)
Change in worst pain intensity over past 7 days
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.
Baseline, 8 weeks (at the end of intervention)
Secondary Outcomes (10)
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.
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.
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.
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.
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.
- +5 more secondary outcomes
Study Arms (2)
Experimental
EXPERIMENTALPatients 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).
Sham Comparator
SHAM COMPARATORSham 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).
Interventions
The study intervention will be participants self-applying 40 tDCS active stimulations with in-person supervision provided by trained study personnel. The self-applied intervention will continue 5 times per week over eight consecutive weeks. Treatment will occur in the home.
In this arm of the study participants will self-apply 40 sham tDCS stimulations with in-person supervision provided by trained study personnel. The self-applied intervention will continue 5 times per week over eight consecutive weeks. Treatment will occur in the home.
