What this trial studies

This observational study aims to determine the safe distance between the skin and pleura during trigger point injections to minimize the risk of pneumothorax. Using ultrasonographic imaging, the study will measure this distance in both sitting and prone positions during inhalation and exhalation. By establishing these measurements, the study seeks to enhance patient safety during trigger point injections, which are commonly used to treat myofascial pain syndrome. The findings could lead to improved protocols for administering these injections.

Who should consider this trial

Good fit: Ideal candidates for this study are adults diagnosed with Myofascial Pain Syndrome who are scheduled for trigger point injections.

Not a fit: Patients under 18 years of age or those with additional diseases, active infections, or known lung diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of complications associated with trigger point injections, enhancing patient safety.

How similar studies have performed: While the approach of using ultrasound guidance in trigger point injections is established, this specific focus on safe distance measurements is novel.
