Summary

This study looks at how many times a needle should be passed through a trigger point to best relieve myofascial pain. 300 adults with chronic muscle pain will be randomly assigned to receive 2, 10, or 20 needle passes during their injection. Researchers will measure pain relief, sleep quality, and satisfaction to find the most effective approach.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
lidocaine and bupivacaine (numbing medicines)
What this could lead to
If it works, this could establish a standard for how many needle passes are needed to get the best pain relief from trigger point injections.
What could go wrong
This is a small, early-phase study. It may not find a clear difference between groups, and results might not apply to all patients with myofascial pain.
