Kinesio Taping(®) is not better than placebo in reducing pain and disability in patients with chronic non-specific low back pain: a randomized controlled trial

BACKGROUND: Kinesio Taping (®) has been widely used in clinical practice. However, it is unknown whether this type of tape is more effective than placebo taping in patients with chronic lower back pain. OBJECTIVE: To compare the effectiveness of Kinesio Taping (®) in patients with chronic non-specific low back pain against a placebo tape and a control group. METHOD: This is a 3-arm, randomized controlled trial with a blinded assessor. Sixty patients with chronic non-specific low back pain were randomized into one of the three groups: Kinesio Taping (®) group (n=20), Micropore(®) (placebo) group (n=20) and control group (n=20). Patients allocated to both the Kinesio Taping (®) group and the placebo group used the different types of tape for a period of 48 hours. The control group did not receive any intervention. The outcomes measured were pain intensity (measured by an 11-point numerical rating scale) and disability (measured by the 24-item Roland Morris Disability Questionnaire). A blinded assessor measured the outcomes at baseline, 48 hours and 7 days after randomization. RESULTS: After 48 hours, there was a statistically significant difference between the Kinesio Taping (®) group versus the control group (mean between-group difference = -3.1 points, 95% CI=-5.2 to -1.1, p=0.003), but no difference when compared to the placebo group (mean between-group difference= 1.9 points, 95% CI=-0.2 to 3.9, p=0.08). For the other outcomes no differences were observed. CONCLUSIONS: The Kinesio Taping (®) is not better than placebo (Micropore(®)) in patients with chronic low back pain.
