Investigating the Effects of Dynamic Neuromuscular Stabilization Exercises on Chest Mobility, Upright Sitting Height, and Quality of Life in Obese Women

Purpose: This study examines the impact of dynamic neuromuscular stabilization (DNS) on chest mobility, upright sitting height, and quality of life (QoL) in obese women. DNS exercises are used to assess and activate the spinal stabilizers to improve the performance of the posture and respiratory systems. Methods: In this semi-experimental study, 60 participants were randomly assigned to two groups as follows: The DNS group (n=30) and the control group (n=30). To start, in a random order, each participant completed a pre-test of the upper chest mobility, lower chest mobility, upright sitting height, and QoL. The DNS protocol was then implemented, with participants undergoing training six times a week for six weeks. After the completion of training, a post-test was conducted to measure all parameters. The data was analyzed using descriptive statistical analysis and repeated measures analysis of variance in the SPSS software, version 23. Results: In the DNS group, significant improvements were observed in the post-test compared to the pre-test for upper chest mobility (2.1±1.6 vs 3.7±1.8 cm, P 0.001), lower chest mobility (2.9±1.4 vs 3.8±1.4 cm, P 0.001), upright sitting height (86.1±3.8 vs 87.7±3.8 cm, P 0.001), and QoL (63.7±17.8 vs 68.2±14.9, P 0.001). On the other hand, the control group did not show statistically significant changes in these parameters. Conclusion: DNS which prioritizes ideal alignment, is an effective protocol for enhancing upper chest mobility, lower chest mobility, upright sitting height, and QoL. It is recommended to incorporate breathing exercises to enhance chest mobility and posture. By doing so, physiological stabilization can be achieved, leading to improvements in the overall health and performance of obese individuals, ultimately enhancing their QoL.
