Objectives:
To assess needle placement accuracy in the rectus abdominis (RA) muscle during dry needling (DN) without entering the peritoneum.
Methods:
Two physical therapists performed DN on a cadaver, making 10 attempts each to needle the RA without entering the peritoneum. Techniques followed two common DN approaches. Ultrasound verified needle depth and safety.
Results:
Seventy percent of attempts were recorded as safe needle placement, while 30% were unsafe. Accurate RA needle placement without peritoneal entry occurred in 55% of attempts.
Discussion/Conclusion:
Inadvertent peritoneal needle placement during RA DN poses risks regardless of experience. Ultrasound guidance may enhance safety and precision in clinical practice.
