The aim of the present clinical trial is to evaluate the efficacy of kinesio taping on patients with chronic low back pain, when the exploration identifies skin/fascia mobilization as a factor that could modify the treatment effect. This study is a randomized controlled trial with intention-totreat analysis. Sixty-two participants with chronic low back pain were therefore recruited from a tertiary referral hospital. Targeted kinesio taping, according to skin/fascia mobility exploration, was applied in the experimental group (17 female/13 male; 49.47 ± 11.15 years) once a week for four sessions. The control group (17 female/14 male; 48.87 ± 9.09 years) underwent a placebo taping application. At post-treatment time there was a statistically significant reduction both in disability (Roland-Morris Disability Questionnaire) and pain (Numeric Pain Rating Scale) in the experimental group (disability: −2.88, 95% confidence interval [CI] −4.56 to −1.21, P < .001; pain: −1.58, 95% CI −2.67 to −0.54 P = .001) and the control group (disability: −1.82, 95% CI −3.46 to −0.17 P = .025; pain: −1.30, 95% CI −2.32 to −0.28 P = .008). However, at six months, these changes only remained significant in the experimental group (disability: −2.95, 95% CI −4.72 to −1.18, P < .001; pain: −1.06, 95% CI −2.07 to −0.04, P < .05). As a conclusion, the application of targeted kinesio taping produced a significant reduction in pain and disability, at 4 weeks and at 6 moths follow-up, although there were no differences between groups at any measurement time point.
