As a result of randomization, dynamic tape was applied to 25 people with a special technique.

As a result of randomization, dynamic tape was applied to 26people with a sham technique.

The dynamic taping application was carried out in 2 stages. Three "I"-shaped tapes were cut. In the first stage, the person was asked to perform scapular retraction, and in this position, the tape was placed by applying medium tension to the anterior part of the other deltoid muscle, passing from the anterior part of the deltoid muscle to the upper thoracic region. In the second stage, the participant was asked to do scapular retraction and depression, and while maintaining this position, medium tension was applied to the lower thoracic vertebra starting from the anterior part of the deltoid muscle and the acromion and tape was applied. Afterward, this process was applied on the other side

To take pictures of the participants, the camera (Logitech, Switzerland) was placed on a tripod with a height of 115 cm and at a distance of 1.5 m (33). In order to maintain the same distance between the camera and the participants, a spot on the ground was marked for the subjects to stand, and the tripod was fixed to the ground. The photos were taken of the left side of the subjects in standing position. Before photographing, reflective markers were placed on the lateral canthus, tragus, 7th cervical vertebra, and acromion. During the photography, the subjects were asked to stand in a comfortable position as in daily life.

Photographs were analysed using the "ImageJ" program and CH angle were calculated and data were recorded. This procedure was performed by a researcher blinded to the study. This is the angle between the horizontal line drawn from the tragus and the line drawn from the tragus to the lateral canthus of the eye. It provides information about the position of the head above the neck and the location of the upper cervical spine.

TK angle was measured with a dual digital inclinometer (JTech IQ Pro™, USA). Participants were asked to stand in a relaxed position. The dual inclinometer device was placed over the spinous processes of the 1st thoracic vertebra and the 12th thoracic vertebra. The measured angle was recorded as the TK angle.
