Effect of the Dynamic Neuromuscular Stabilization Technique on Functional Capacity in Overweight and Obese Individuals: A Randomized Controlled Trial

Background Individuals with overweight and obesity (OW/OB) have poor performance in weight-bearing exercises, resulting in low functional capacity. The dynamic neuromuscular stabilization (DNS) technique was created to engage the core-postural chain in conjunction with the core muscles, generating enough intra-abdominal pressure to dynamically support the spine through muscular activity. DNS is a strategy that emphasizes the activation of the spine's intrinsic stabilizers, as well as proper breathing patterns, before any intended functional movement. The aim and objective of this study was to determine the effectiveness of the DNS technique on functional capacity in OW/OB individuals and to compare the effectiveness of the DNS and conventional approach. Methods The study recruited 100 individuals, who were separated into an experimental group (DNS technique) and a control group (conventional exercises), each with 50 participants. Outcome measures, including a six-minute walk test (SMW test) and body mass index (BMI), were taken pre-treatment and post-treatment. Results and discussion Based on the inclusion criteria of this study, the age group included was 20 to 25 years old. Pre- and post-treatment statistically significant changes were observed in the experimental and control groups in the BMI and SMW test. However, the BMI (kg/m(2)) was not statistically significant in the experimental group (t-value=-0.15, p=0.87) and control group (t-value=-0.22, p=0.82). Moreover, in the SMW test (meter), no statistical significance was found in the experimental group (t-value=-0.15, p=0.87) and control group (t-value=- 0.22, p=0.82). Conclusions Both groups are effective in increasing the functional capacity of obese and overweight individuals. The study indicates a strong need for further research into its long-term effectiveness in the OW/OB population.
