Effect of Dynamic Neuromuscular Stabilization Breathing Exercises on Respiratory Function of Sedentary Students with Poor Posture

Aims: Dynamic neuromuscular stabilization approach, as functional mechanisms, evaluate and activate the local spinal stabilizers to optimize the performance of posture and respiratory for both prevention and rehabilitation. But the outcomes of this approach remain unclear. So the aim of this study was to evaluate the change in respiratory function in response to DNS breathing exercises in sedentary students with poor posture. Materials & Methods: This experimental study was carried out on ۲۶ poor posture sedentary male students that were selected by purposive sampling method. First, a pretest of the respiratory function including Maximum voluntary ventilation (MVV), Forced expiratory volume in first second (FEV۱), Forced vital capacity (FVC), and FEV۱/FVC ratio were done for each participant. DNS breathing exercise protocol was trained for ۶ weeks (۶ sessions per a week) and after completion of training, post-test was performed from all parameters. The statistical analysis was performed by SPSS ۱۶ software and paired-sample T test. Findings: After ۶ weeks, significant improvements were observed compared to baseline in spirometry parameters including MVV, FEV۱, FVC, and FEV۱/FVC ratio (p<۰.۰۰۱). Conclusion: DNS breathing exercise is an effective protocol to improve respiratory function.
