Abstract

Objective:

To investigate the effect of setting expectations verbally on the effectiveness of kinesiotape application in patients with a rotator cuff tear.

Design:

Randomized controlled, double-blind study.

Setting:

Department of Physiotherapy and Rehabilitation.

Subjects:

Eighty-nine patients with rotator cuff tear.

Intervention:

Patients were randomized according to the verbal input given to patients about the effectiveness of kinesiotaping; Group 1 (there is no evidence that kinesiotaping is effective), Group 2 (there is limited evidence that kinesiotaping is effective), and Group 3 (there is evidence that kinesiotaping has an excellent effect).

Main measures:

Resting pain, activity pain, and night pain were assessed by visual analog scale. Range of motion was assessed by a universal goniometer. Function was evaluated by the Disabilities of the Arm, Shoulder and Hand Questionnaire and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form before and 24 hours after kinesiotape application. Only resting pain and activity pain were assessed after 30 minutes.

Results:

There were no statistically significant differences (ANOVA) between any groups at the three assessment points. The intragroup assessment showed that in Group 2, only resting pain after 30 minutes improved (3.2 ± 2.9 to 2.6 ± 2.8; P  = 0.02). An improvement in resting pain both after 30 minutes and after 24 hours was found in the third group (4.1 ± 2.4 to 2.3 ± 2.3, P  = 0.001; 4.1 ± 2.4 to 2.2 ± 2.3, P  = 0.001, respectively). Activity pain and night pain were improved in all groups after 24 hours.

Conclusion:

Setting positive expectations verbally about kinesiotaping might be effective in reducing pain in patients with rotator cuff tear.
