14 seated male workers with rounded shoulder posture were randomized to undergo Kinesiology taping with 35-40% stretch applied to one shoulder, and placebo Kinesiology tape with 0% stretch applied to the other shoulder. Outcomes of interest were pectoralis minor length, supine measurement of rounded shoulder posture, and total scapular distance, measured immediately after taping. Significant effects were noted in both dominant and non-dominant shoulders treated with active Kinesiology tape, while no significant pre- to post-test changes were observed in the shoulders treated with placebo Kinesiology tape.
