Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Each patient eligible will be seen by a member of the research team and given information about the trial verbally and via a patient information sheet. After giving written consent each participant will be allocated a sealed opaque envelope containing two wristbands ( either active or placebo) with instructions on how to apply them - these bands will be applied by the recruiting research team member and covered in a soft bandage to conceal band type from observers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
340 subjects have been randomized in a 1:1 ratio (Active or Placebo) using a computer generated random number sequence and the appropriate band (Active or Placebo) plus application instuctions placed in numbered sealed envelopes
Masking / blinding
Blinded (masking used)
