Could a tiny needle zap away shoulder pain? new trial tests best frequency
NCT ID NCT07269925
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two electrical frequencies (high vs. low) used in percutaneous electrical nerve stimulation (PENS) for shoulder pain. Thirty adults with a trigger point in the infraspinatus muscle will receive a single session, and researchers will measure changes in muscle strength and pain sensitivity. The goal is to find the optimal dosage for this technique, which is still being explored for chronic pain.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Percutaneous electrical nerve stimulation (PENS) at high or low frequency
What this could lead to
If successful, this could help identify the best electrical frequency for easing shoulder pain and improving muscle strength using a needle-based stimulation technique.
What could go wrong
This is a small, early-phase study with only 30 participants and no control group, so results may not apply broadly. The technique is still experimental and its benefits over standard treatments are not proven.
