Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are sequentially recruited by participating physicians during clinic visits. After giving the written consent, patients are randomly assigned to the placebo group or the active treatment group by sealed opaque envelopes. Instructions and explanations are provided equally to all patients. Patients are advised that they may discontinue participation in the study at any time without penalty, and that their healthcare treatment would not otherwise be affected. The participating doctor(s) or assistants teach the patients how to evaluate discomfort using a visual analogue scale (VAS), where the scored from “0” for no discomfort, to “10” for most discomfort. The three stages of the test were then described to each patient: baseline rating, 2 min of hand pressure while lying down, and post-pressure rating at the specified times.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization of patients using the method of Random Permuted Blocks with allocation ratio one to one. The random number designations are placed in sealed opaque envelopes. Each patient blindly drew one from the envelope.

Brief summary
To determine whether the method will or will not significantly relieve clinical non-painful discomfort. The study hypothesis is that a acute manual stimulation correctly applied to the right areas of skin could relief non-painful discomfort.
