Purpose: The objective of this study was to examine the changes in muscle activity on the anterior deltoid muscle depending on the stretch rate of kinesio tape when applying kinesio tape in healthy adult subjects.
Methods: This study was a single-blind randomized controlled trial, including 22 healthy participants (male 15, female 7) with no pathology or past history of shoulder who participated voluntarily. Participants applied a different stretch rate of the kinesio tape, and the functional activity was tested. The stretch rate of kinesio tape was 0%, 10%, and 20%. Subjects lifted a weight (5% of their body weight) to their shoulder height. Subjects lifted a weight up to an angle of 90 degrees in the sagittal plane, and muscle activities (biceps brachii, anterior deltoid, middle deltoid, upper trapezius) were assessed using EMG (electromyography). Analysis of muscle activity was divided into two parts (lift weight and keep holding). The EMG activity of each muscle was normalized to the value of reference voluntary contraction (%RVC) and explored using repeated ANOVA.
Results: There were no significant differences in muscle activity depending on the ratio of tape stretch when lifting a weight (p>0.05). There were no significant differences in muscle activity depending on the ratio of tape stretch when holding a weight (p>0.05).
Conclusion: According to the results of this study, in the case of applying kinesio taping therapy for healthy people, it was found that the stretch rate of the tape does not have an effect on muscle activity.
