Blinding
and Randomisation
The patients can only be blinded with respect to the
acupuncture treatment given. Blinding
with respect to the
standard therapy is not possible. The investigator cannot be blinded. The
WOMAC, the global patient assessment, and the SF12 are
measured during a telephone interview
performed by a
call centre. The person performing the interview is blinded with respect
to the therapy of
the patient. Patients blindness to the mode of
acupuncture is assessed after
the last follow up
by asking the patient to guess their group assignment. Additionally, patients
are asked directly
after the intervention phase for the quantity of care they have received during
the treatments.
The 1:1:1 block-randomisation, stratified by the trial
centre, is performed from an independent
centre via
fax.
