New needle therapy could ease CrossFit shoulder pain
NCT ID NCT06958276
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested a treatment called ultrasound-guided percutaneous neuromodulation (PNM) in 42 CrossFit athletes with long-lasting shoulder pain of unknown cause. The treatment uses thin needles placed near nerves to deliver mild electrical stimulation. Researchers measured changes in shoulder strength, mobility, and muscle function to see if PNM helps reduce pain and improve performance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ultrasound-guided percutaneous neuromodulation (electrical stimulation via needles near nerves)
- What this could lead to
- If it works, this could offer a new physiotherapy option to ease shoulder pain and improve strength and mobility in CrossFit athletes.
- What could go wrong
- This is a small, early-stage study with only 42 participants. It may not show clear benefits, and results may not apply to all athletes or other types of shoulder pain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * Be over 18 years old. * Have shoulder pain lasting more than 3 months. * The pain must not have an apparent cause, meaning there is no specific diagnosis, and thus it is considered nonspecific pain. * Train CrossFit at least 3 days per week. Exclusion criteria: * Have received any medical or physiotherapy treatment for nonspecific shoulder pain. * Have had previous shoulder surgery. * Present fear of needles (belonephobia) or fear of the US-guided PNM intervention.
