The Effect of Motor Imagery Training in Addition to Core Stabilization Exercises on Core Performance, Balance, Functional Capacity, and Quality of Life in Healthy Adolescents Girls

The Modified Push-Up Test will be used to assess the measure the strength and endurance of the upper extremity. The participant is positioned face-to-face on the arm, the knees and elbows are folded, and the hands are in the shoulder line and next to the body. The individual is asked to lift his upper body and body from the ground, bringing his elbow to extension without disturbing the flexion in his knees.

The Sit-Up Test will be used to assess the core performance. The knees are bent, the feet are on the ground, and the arms lie on the back in a crossed position on the chest. The participant is asked to raise his back to 90 degrees from the ground within 30 seconds and then take the starting position again. Supporting the feet helps to move. The movement starts when you are on the back, and when you get to the same position, 1 is counted again.

The Flamingo Test will be used to assess the duration of static balance on a single foot. The participant is held on a wooden platform with a length of 50 cm, holding one foot back on the platform with the hand on the same side, and holding it like a flamingo. Run to balance with the remaining free arm, the test practitioner holds his arm to balance and starts the period when he leaves his arm. The disturbance of the position is stopped when the foot moves and the hand leaves the leg, and the time is continued again when the participant is ready. The period until the loss of balance is calculated, and the number of losses, disruptions, or falls within 60 seconds is recorded during balancing. Participants who drop more than 15 in the first 30 seconds are awarded zero points.

Y-balance test which is a modification of the Star Excursion Balance Test (SEBT) will be used to assess the balance. The participant, standing on his preferred foot on a 50 cm long wooden platform on a 4 cm high and 3 cm wide balance platform (flamingo balance test), tries to stay in balance for 1 minute by bending the other foot from the knee, pulling it to the hip, and holding it with the same hand on the same side.

The 6-minute walking test will be used to assess the functional capacity. Participants will be recorded in a 30-meter straight corridor for 6 minutes at their own walking speed, as fast as possible but without running. The walking distance will be recorded in meters.

The Motion Imaging Survey - Revised Second Edition will be used to assess the visual and kinesthetic imaging skills. It consists of a total of 14 elements, including visual and kinesthetic imaging. Scores that can be obtained from the scale range between 14-98. High scores mean that the level of visual imagery is also high.

Vividity of Movement Imagery Questionnaire 2 will be used to assess the participant's imaging ability. Scores that can be obtained from the scale range between 16-80. High scores mean that the level of visual imagery is high; low scores mean that the level of visual imagery or visualization is low.

The Pediatric Quality of Life Questionnaire of the International Quality of Living Scale for Children will be used to assess the quality of life of children and adolescents. Scores that can be obtained from the scale range between 0-100. High scores mean better condition.
