This Study Aimed to Evaluate the Effect of Dynamic Neuromuscular Stabilization (DNS) on Pain Intensity and Functional Disability in Women With PLBP as Common Problem Affect t he Women After Birth Which Often Impacting Their Quality of Life and Ability to Perform Daily Activities

"Distinguishing Description for DNS Intervention~This intervention consists of a structured Dynamic Neuromuscular Stabilization (DNS) exercise program specifically tailored for post-partum women with mechanical low back pain. DNS emphasizes restoring functional motor patterns through:~Breathing-based core activation techniques~Developmental positions mimicking infant motor milestones (e.g., supine 90/90, quadruped, side-lying)~Coordination of the diaphragm, pelvic floor, and transverse abdominis muscles~Progressive motor control retraining over 6 weeks, 3 sessions/week~What distinguishes this intervention:~It integrates developmental kinesiology principles with respiratory-pelvic-lumbar coordination.~DNS is performed under supervised sessions by a physiotherapist, ensuring precision and progression.~This protocol replaces standard strengthening/stretching exercises and focuses on neuromuscular re-patterning, not just symptom relief."

"1-Therapeutic Ultrasonic: comparison group also received treatment through therapeutic ultrasound, which was applied three times per week. The ultrasound therapy was delivered to the paraspinal muscles of the lumbar region, using a stroking technique where each stroke overlapped by about 50% with the preceding stroke. The ultrasound used a frequency of 3 MHz and an intensity range of 1.0 to 1.5 W/cm²,The ultrasound head was placed over the L4 to L5 and L5 to S1 regions and moved in a circular motion for a total duration of 5 minutes per treatment session (Shobari et al., 2024).~infra red the infrared lamp was placed at 75 cm distance from the patient's back so that the radiation struck the surface at or near a right angle to achieve maximum penetration. The treatment duration was 15 minutes. Each woman with post-partum low back pain was treated by 20 minutes infrared irradiation 40 cm away from the low back region, from prone3 sessions per week for 6 weeks (El-Lassy and Madian, 2018"
