Dynamic Neuromuscular Stabilization (DNS) principles significantly increase abdominal wall tension (AWT) across various postures. The bear position demonstrated the greatest AWT activation, highlighting DNS
Area of Science:
- Biomechanics
- Human Movement Science
- Rehabilitation Medicine
Background:
- Intra-abdominal pressure (IAP) is crucial for spinal and trunk stabilization.
- IAP regulation involves coordinated action of abdominal muscles, diaphragm, and pelvic floor muscles.
Purpose of the Study:
- To compare abdominal wall tension (AWT) in different postural positions.
- To evaluate the effect of Dynamic Neuromuscular Stabilization (DNS) principles on AWT.
Main Methods:
- Cross-sectional observational study with 30 healthy participants.
- Ohmbelt sensors measured AWT in sitting, supine leg raise, squat, bear, and hang positions.
- AWT was assessed spontaneously and after DNS-guided verbal and manual instructions.
Main Results:
- DNS instructions significantly increased AWT compared to spontaneous activation (p < .01).
- The bear position showed the greatest AWT increase.
- No significant gender-based differences in AWT were observed.
Conclusions:
- Verbal and manual DNS guidance substantially enhances abdominal wall activation.
- The bear position is most effective for maximizing AWT through DNS principles.

Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
