The true taping method was applied to the first group according to the method determined by Kase. According to this method, a 2-inch (5 cm) wide beige-colored Kinesio tape (Kinesio® Tex Gold FP) was measured from the second-third metacarpal base to the lateral epicondyle while the elbow was extended and the wrist was in the neutral position and the tape was applied in the shape of a 'Y'. In a position where the wrist-ankle extensors were most tense (wrist-ankle extension - forearm pronation), the anchor point of the tape was applied to the insertion of the muscle without creating any tension. Then, the tape was applied to the medial and lateral edges of the wrist extensors by applying a 15-25% tension towards the origin of the muscle. Both ends of the Y-shaped tape were terminated without tension on the lateral epicondyle.

In the placebo group, the 10 cm I-shaped tape was placed 5 cm inferior to the lateral epicondyle using the same Kinesio tape in the study group. It was applied transversely, starting from the painless side of the midline on the forearm extensor face directing towards the lateral side of the forearm without a tension.

The tape is an elastic cotton strip with an acrylic adhesive that is used with the intent of treating pain and disability

The numerical rating scale (NRS) was used to evaluate the pain level of the patients included in the study. It is a one-dimensional scale consisting of 11 items that measure pain intensity in adults and is a segmented - intermittent numerical version of the visual analogue scale (VAS).

According to the Cyriax method, each joint tested was kept in the mid- range of motion, without allowing movement. Resistance was applied to the forearm distal to avoid muscle involvement other than that tested in pronation and supination, thus the wrist was prevented to be involved. Subsequently, the patients were asked to apply a maximum force for at least three seconds. Resisted wrist extension, third finger extension, elbow supination, and pronation were evaluated.
