Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients have never been exposure to this analgesic method before, then are unware of the difference between placebo and treatment.
All the introduction and procedures are same to the patients from both treatment and placebo group, except the different level pressure, which blind to patients, but not to physicians.
Each patient draws from an envelop a number which shows the allocation group the subject would be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
