The effectiveness of Kinesio Taping(R) for mobility and functioning improvement in knee osteoarthritis: a randomized, double-blind, controlled trial

Objective: To evaluate the effectiveness of the Kinesio Taping(R) method for mobility and functioning improvement for patients with knee osteoarthritis (KO). Design: Randomized, double-blinded, controlled trial. Setting: Outpatient rehabilitation department. Subjects: A total of 187 subjects with symptomatic I-III grade KO participated; of these, 157 subjects were included in the analyses (intervention group, n = 81 (123 knees); control group, n = 76 (114 knees). Intervention: The intervention group received a specific Kinesio Taping application, and the control group received non-specific knee taping for a month. Main measures: Changes in Knee injury and Osteoarthritis Outcome Scores (KOOS), knee active range of motion, 10-Meter Walk, and the five times sit to stand tests (5xSST) were assessed at baseline, after four weeks of taping, and a month post taping intervention. Subjective participants' experiences and opinions on the effect of knee taping were evaluated. The chosen level of significance was p < 0.05. Results: The mean age of participants was 68.7 +/- 9.9 in intervention group and 70.6 +/- 8.3 in control group (p > 0.05). The change from baseline in gait speed in the intervention group after taping month was +0.04 +/- 0.1 m/s, at follow-up +0.06 +/- 0.1 m/s; in control group +0.07 +/- 0.1 m/s, and +0.09 +/- 0.1 m/s; the change in time needed to accomplish 5xSST was -2.2 +/- 3.2 seconds, at follow-up -2.4 +/- 3.1 seconds; in control group -2.8 +/- 3.6 seconds, and -2.4 +/- 4 seconds. Improved knee flexion and enhancement in functioning assessed by KOOS were noticed in both groups, with lasting improvement to follow up. No difference in the change in the above-mentioned outcomes was found between groups (p > 0.05). Fewer subjects (6.2% (5) vs. 21.1% (16), chi(2) = 7.5, df = 2, p = 0.024) from Kinesio Taping group were unsure if taping alleviated their mobility and more intervention group patients indicated higher subjective satisfaction with the effect of knee taping to symptom and mobility alleviation than control group (p < 0.005). Conclusion: Investigated Kinesio Taping technique did not produce better results in mobility and functioning improvement over non-specific knee taping; however, it had higher patient-reported subjective value for symptom attenuation and experienced mobility enhancement.
