Scapula and Upper Extremity Performance in Scoliosis

The test will be used to assess upper extremity explosive power. Participants will be positioned in an upright chair without armrests, with their ankles, knees, and hips at 90 degrees. They will be asked to grasp a 3-kg medicine ball with both hands and throw it overhead without bending their bodies forward or flexing their elbows. The first point where the ball touches the floor will be measured from the starting point, and the value will be recorded in cm. The test will be repeated three times, and the average will be recorded. If participants throw the ball down to neck level or by bending forward from the body, the test will be invalid and the test will be repeated.

This is a dynamic test in which the individual, using weights determined by the individual's body weight, actively abducts and flexes their arms bilaterally and with the weight in hand. These movements are repeated several times, and scapular winging, scapular asymmetry, and abnormal movements during these movements indicate the presence of scapular dyskinesis. The type of scapular dyskinesis is determined after these repetitions.

The Scapular Lateral Slip Test, as defined by Kibler, is a semi-dynamic test commonly used to assess the presence of scapular dyskinesis. The individual to be tested was assessed in a standing position with their back turned and open. In the test performed to assess dominant and non-dominant scapular positions, the distance between the spinous process of the T3 vertebra and the medial end of the scapula root (spinal root) and the distance between the spinous process of the T7 vertebra and the inferior end of the scapula were measured with a tape measure and recorded in centimeters (cm). A difference of more than 1.5 cm between the dominant and non-dominant side measurements indicates a positive test.
