Kinesiotape and quadriceps strengthening with elastic band in women with knee osteoarthritis and overweight or obesity. A randomized clinical trial.
BACKGROUND
The beneficial effects of exercise in the treatment of Osteoarthritis (OA) of the knee have been verified in several studies. Kinesiotaping (KT) has been popularized due to its reducing local pressure and increasing circulation, resulting in decreased pain.


OBJECTIVE
Determine the clinical effectiveness of strengthening therapy with KT in women with knee OA for pain reduction.


METHODS
Thirty two women with knee OA, aged 50-70 years, with overweight or obesity grade I, who were randomized into two groups: one with exercise and KT, and the other, with exercise and placebo technique. Both groups performed stretching and quadriceps strengthening exercise with the elastic band 3 days weekly for 6 weeks. Measurement of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale was taken as primary outcome. Stiffness and functionality of the same index and the Visual Analog Scale (VAS) for pain intensity were measured.


RESULTS
At the end of the study, there were no significant differences between the groups. Both groups had a difference of 2.7 points with respect to the baseline measurement, change percentage of 32.2% and 31.1% for placebo and experimental respectively (p=0.2).


CONCLUSIONS
KT plus quadriceps strengthening exercise does not offer advantages for improvement of pain compared with quadriceps strengthening exercise alone in knee OA.
