Analysis of Scapular Musculature Activation During Targeted Abdominal Contraction with Scapular Stabilization Exercises

Abdominal contraction will be taught before exercise. They will be instructed to tighten their abdomen as if they were wearing tight pants and not to hold their breath. The visual biofeedback unit will be placed between the therapy table and the participant's abdominal area and will be used to monitor the contraction of the abdominal muscles. The visual biofeedback inelastic bag will be inflated to 70 mmHg and the participant will be instructed to draw the abdomen in and maintain the position. The participant will be asked to maintain a pressure of 60 mmHg during scapular retraction with visual feedback from an analog pressure gauge. Pressure changes of ± 5 mmHg due to breathing will be allowed. During exercise, the patient will be asked to perform the exercises while maintaining the pressure on the visual biofeedback.

"Exercises;~1. Scapular retraction with arms next to the trunk~2. Scapular retraction with arms abducted at 45 degrees,~3. Scapular retraction with arms 90 degrees abducted,~4. Scapular retraction exercises with arms 120 degrees abducted The exercises will be performed with the shoulder head off the bed. The exercises will be repeated 3 times with 5 seconds rest between repetitions. To reduce the effect of fatigue, 2 minutes rest will be given between exercises. Each exercise will be performed with 3 seconds of concentric, 3 seconds of isometric and 3 seconds of eccentric contraction and muscle activation of UT-LT and SA muscles will be measured during these phases."
