The primary objective to this study was to determine the effects of kinesio tape (KT) on shoulder ROM arc pre and post KT treatment. The experimental design consisted of a pretest-posttest randomized-group. Independent variables were treatments with two levels: no KT and KT. Dependent variables were shoulder internal and external rotation. Shoulder internal and external rotation was measured with a digital inclinometer on 45 healthy subjects (control group = 22, KT group = 23), while perceptions of participation and KT efficacy was measured with an electronic post-experiment questionnaire. Results showed no significant differences between control and KT treatment groups for shoulder ROM arc pre and post intervention. Significant differences were identified between females (x=125°) and males (x=115°) within each group on day 4 pre tape removal. Overall, females displayed a significant increase in ROM arc with KT after 4 days of treatment, and returned to baseline arc upon tape removal.
