THE EFFECTS OF SCAPULAR STABILIZATION EXERCISES ACCOMPANIED BY SPINE STABILIZATION EXERCISES USING AN UNSTABLE SURFACE ON MUSCLE ACTIVITIES AND WINGING DISTANCE FOR MEN AND WOMEN WITH SCAPULAR WINGING

Abstract

Background: Scapular kinematics are important indicators of dyskinesis, often suggesting underlying shoulder pathology, but
the influence of sex is unknown. The aim of this study was to compare the difference in muscle activity and winging distance
between men and women with scapular winging in scapular stabilization exercises accompanied by spine stabilization
exercises using an unstable surface.
Methods: This study included 30 subjects with scapular winging. The experimental group performed scapular stabilization
exercises accompanied by spine stabilization exercises on an unstable surface, while the control group performed scapular
stabilization exercises. Each group performed exercises for 40 minutes three times a week for four weeks. To investigate the
intervention effects, the activity of the muscles around the shoulder and the winging distance were measured.
Results: The serratus anterior and lower trapezius activation levels in the experimental group were significantly greater in
men than in women. The activation of the serratus anterior in the experimental group was significantly increased compared to
the control group. The activation of the pectoralis major was significantly decreased in the experimental group compared to
the control group.
Conclusions: As a result, scapular stabilization exercises accompanied by spine stabilization exercises on an unstable surface
a greater effect seen than treatment with scapular stabilization exercise alone; thus, this combination treatment can be
recommended as an effective exercise. The effect of the exercise on men in this experiment was greater than that on women;
thus, the exercise methods can be recommended for use in men’s health exercise programs.
