BACKGROUND: The purpose of this study was to investigate the immediate effects of Kinesio-taping (KT) on scapular muscle endurance and strength and compared to placebo Kinesio-taping in asymptomatic subjects. METHODS: Thirty-nine asymptomatic subjects were included in this study. Subjects were randomly allocated to KT (with the muscle facilitation technique) and placebo-KT (without any technique and tension). Scapular isometric muscle endurance was measured with a scapular muscle endurance test. The strength of the upper, middle, and lower trapezius, and serratus anterior was assessed using a hand-held digital dynamometer. Data were analyzed with 2x2 (groups [KT and Placebo-KT] x time [pre- and post-intervention]) mixed-model ANOVA. RESULTS: There were no significant main effect of time and time x group interaction was found for scapular muscle endurance, middle and lower trapezius strength. For the upper trapezius muscle strength main effect of time (F1,37 = 11,629, P=0.002, partial η2=0.239) and time x group interaction (F1,37 = 7.502, P=0.009, partial η2=0.169) were found, indicating an increase in KT group. However, this increase did not make a difference between groups. There was an interaction effect (time x group) for the serratus anterior muscle strength (F1,37 = 7.770, P=0.008, partial η2=0.174), demonstrating a decrease in the placebo-KT group. Similarly, this situation did not create a difference between groups. CONCLUSIONS: These results suggest that the use of KT in asymptomatic subjects has no immediate effects on scapular muscle endurance, trapezius, and serratus anterior muscle strength compared to the use of placebo-KT.
