Study data

Table of the subject characteristics and treatment outcomes in a double-blind, domiciliary, self-administered tDCS study.

"Pre" and "Post" refer to the beginning of the first training & treatment session, and to the follow-up visit 4 weeks after the first session, respectively.

Q1–Q8 refer to questions in a non-standard questionnaire that was mapping the user experience aspects of the trial. There were eight yes/no-questions regarding the treatment:
Q1) “Did the treatment have any effect on tinnitus loudness?”,
Q2) “Did the treatment have any effect on tinnitus annoyance?”,
Q3) “Did the treatment have any effect on your mood?”,
Q4) “Did the treatment cause any adverse effects?”,
Q5) “Did you experience any uncomfortable sensation on your skin during treatment?”,
Q6) “Based on your user experience, was the device you were given a sham device?”,
Q7) “Did the treatment have any effect on you falling asleep or on the quality of sleep?”,
Q8) “Was it difficult to prepare the device and accessories before treatment?”.
Patients were also encouraged to elaborate their answers in free-form. These answers were collected right after the ten-day treatment period had finished.
