PMID 41707127WHAT IT FOUND
Most patients with chronic shoulder pain reported at least 50% pain relief after 60 days of peripheral nerve stimulation.
Success was higher when stimulation lasted over 45 days and used both sensory and motor fibers. Diabetes reduced success unless motor stimulation was included.
Key findings
0175% of patients with available data reported at least 50% pain relief at the end of treatment.
02Bimodal stimulation (combining sensory and motor) resulted in significantly higher response rates compared to sensory or motor stimulation alone.
03Patients who received treatment for at least 45 days were significantly more likely to respond than those who terminated early.

What it does not show
This is a retrospective chart review, so it cannot prove that PNS caused the pain relief; other factors could have influenced outcomes. The study only looked at pain relief at the end of the 60-day treatment, so it does not show if the benefits lasted longer. Outcomes were based on patient-reported pain relief, which can be subjective. Some data came from the device manufacturer's database, which could introduce bias, although the authors stated sensitivity analyses showed no significant difference between data sources.
Declared interests
The study was funded by SPR Therapeutics, the manufacturer of the PNS device.
The easy way to misread this
Do not assume this treatment works for everyone or that the pain relief is permanent. The study only measured pain relief at the end of the 60-day trial and did not assess long-term outcomes or functional improvements.
