A comparison of the effects of shoulder stabilization exercises in addition to office exercises on skapular dyskinesis, muscle strength, posture and proprioceptive sensory parameters in the office workers with shoulder protraction

The aim of this study was to compare the effects of shoulder stabilization exercises (SE) given in addition to office exercises (OE) on scapular dyskinesis, muscle strength, posture and proprioceptive sensory parameters in office workers with shoulder protraction. 60 individuals aged between 25-35 years were divided into two groups by stratified random sampling. While OE was given to both groups, individual shoulder SE was also applied to the study group. All individuals were evaluated at the beginning, 8th week and 12th week. Working area and ergonomic risk analysis as well as shoulder protraction, pectoralis minor length, total scapula distance and scapular dyskinesis with caliper; passive shoulder mobility with electronic goniometer; active shoulder mobility with a tape measure; glenohumeral horizontal adduction and scapula upward rotation by electronic inclinometer; postural analysis by photographing method; muscle strength with hand-held dynamometer; proprioception with isokinetic dynamometer; vibration sense with vibrometer and upper extremity performance with Closed Kinetic Chain Upper Extremity Stability Test were evaluated. At 8th and 12th weeks, there were significant improvements in all parameters examined in the study group, while improvements in shoulder mobility and flexibility, dominant extremity upper trapezius and pectoral, non-dominant extremity anterior deltoid, serratus anterior and infraspinatus muscle strength and upper extremity physical performance were found in the control group (p<0.05). In the comparison between the groups, significant difference was found in favor of the study group, especially in posture, muscle strength, proprioception and vibration sense and the improvements continued in the follow-up period, resulting in a more permanent effect (p<0.05). Considering the protective effect of proprioceptive sense from long-term injuries, together with the developments in posture and body mechanics, it was thought that it would be beneficial to use SE in addition to OE in office workers, as a complementary approach, especially in primary health care services.
