Clinical Trial Summary

The investigators hypothesize that delivery of anodal tDCS to the left frontal head region will reduce fatigue severity following stroke.

Description:

The purpose of this study is to investigate transcranial direct current stimulation (tDCS) as a home-based non-pharmacologic intervention for post-stroke fatigue (PSF). Investigators will perform a double-blind, sham-controlled, randomized clinical trial with 24 subjects; 12 will receive sham stimulation and 12 will receive real stimulation. After a baseline assessment, the tDCS device will be applied for 20 minutes, once daily over the left dorsolateral prefrontal cortex (DLPFC), for a total of two weeks. Follow-up assessments with outcome metrics will be completed after the seventh and fourteenth sessions, and one-month following the start date (2 weeks post-treatment). In a randomly selected subset of both real and sham participants, rs-fMRI will be completed at baseline and post-treatment.

Intervention

Device:
• Real Soterix Mini-CT tDCS stimulator
Real transcranial electrical stimulation at 2mA intensity will be delivered to the left dorsolateral prefrontal cortex, 20 minutes/day, 14-day duration.
• Sham Soterix Mini-CT tDCS stimulator
Sham stimulation to the left dorsolateral prefrontal cortex, 20 minutes/day, 14-day duration. The device will ramp up and ramp down current delivery from 0 mA -2 mA - 0 mA over 30 seconds at the start of the 20-minute protocol with no active stimulation until the end of the 20 minutes, at which time the 30-second ramp up/ramp down will be repeated.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean change from baseline Fatigue Severity Scale - 7 (FSS-7)	Fatigue Severity. This seven item scale measures fatigue severity and it's effect on a person's lifestyle and activities. Items are scored on a seven point scale. Minimum score = 7, maximum score = 49 with higher score indicating greater fatigue severity.	Screening (-1 to -14 days), Baseline (Day 1), During-treatment (Day 7-9), Post-Treatment (Day 14-21), 1 Month Post-Treatment (Day 45-52))
Secondary	Mean change from baseline Stroke Specific Quality Of Life scale (SS-QOL)	Quality of Life. Assesses health related quality of life, specific to individuals with stroke. Composed of 49 items, score on a 5 point guttman type scale. Scores range from 49 to 245, with higher score indicating better functioning.	Baseline (Day 1), During-treatment (Day 7-9), Post-Treatment (Day 14-21), 1 Month Post-Treatment (Day 45-52)
Secondary	Mean change from baseline Patient Health Questionnaire - 9 (PHQ-9)	Depression. A multipurpose instrument for screening, measuring, and monitoring severity of depression. Scores range from 0-27, with higher score indicating greater severity of depression.	Screening (-1 to -14 days), Baseline (Day 1), During-treatment (Day 7-9), Post-Treatment (Day 14-21), 1 Month Post-Treatment (Day 45-52)
Secondary	Mean change from baseline Generalized Anxiety Disorder - 7 (GAD-7)	Anxiety. A multipurpose instrument for screening, measuring, and monitoring severity of anxiety. Scores range from 0-21, with higher score indicating greater severity of anxiety.	Screening (-1 to -14 days), Baseline (Day 1), During-treatment (Day 7-9), Post-Treatment (Day 14-21), 1 Month Post-Treatment (Day 45-52)
Secondary	Mean change from baseline PROMIS-sleep disturbance	Sleep. A domain focused self report of global, physical, mental, and social health for those living with a chronic condition. Computer adapted test with higher scores indicating more sleep disturbance. Results reported as a T-score with range from 10-90 based on the United States general population average score of 50 and standard deviation of 10. Higher t-score indicates greater sleep disturbance.	Baseline (Day 1), During-treatment (Day 7-9), Post-Treatment (Day 14-21), 1 Month Post-Treatment (Day 45-52)
Secondary	Mean change from baseline Symbol Digit Modalities Test (SDMT)	Cognition. A measure of cognitive processing speed and attention. Scores range from 0-120, with higher scores better performance.	Baseline (Day 1), Post-Treatment (Day 14-21)
Secondary	Mean change from baseline Test of Variables of Attention (T.O.V.A)	Cognition. A computerized test that measures short-term memory, with scores from 85-115 indicating a normal result. Response time, response time variability, commissions, and omissions are also recorded. A higher total number correct score indicates better performance.	Baseline (Day 1), Post-Treatment (Day 14-21)
Secondary	Mean change from baseline Montreal cognitive assessment (MoCA)	Cognition. A brief screening tool to assess global cognitive functioning and detect mild cognitive dysfunction. Scored from 0-30 with higher score indicating better performance.	Baseline (Day 1), Post-Treatment (Day 14-21)
