The WOMAC (Western Ontario and McMaster
Universities) index 5 was used to evaluate the
therapeutic effects at baseline and at the subsequent
weeks. The items on the WOMAC index included
3 dimensions—pain (5 questions), stiffness (2
questions) and physical function subscales (17
questions)—and were rated on an ordinal scale of 0to 4, with the lower scores indicating lower levels of
symptoms or physical disability. The validation study
reported internal consistencies for the pain, stiffness
and physical function subscales of 0.86, 0.86 and
0.95, respectively.6
Reliability for the pain, stiffness
and physical function subscales were 0.68, 0.48 and
0.68, respectively.7
