Masking Details
Since the subject sets the stimulation settings for each day of treatment, it is not possible to employ a full placebo with this device. We will inform the subjects that we are uncertain whether short stimulation of 1 minute is less effective than is longer stimulation of 30 minutes, which is a true statement according to our current state of knowledge. We will use a balanced deck of randomized cards setting the initial treatment arm as SHORT in 15 cases and LONG in 15 cases.
