New nerve block may keep arm strong after shoulder surgery
NCT ID NCT07057947
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This trial tests whether a newer type of nerve block, called the pericapsular nerve group (PENG) block, can control pain during shoulder arthroscopy without weakening the arm muscles as much as the standard interscalene block. Sixty adults having shoulder surgery will receive one of the two blocks before their operation. Researchers will measure how quickly hand grip strength returns and how well pain is controlled afterward.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
local anesthetic (e.g., bupivacaine)
What this could lead to
If PENG block works as well for pain but spares muscle strength, patients could recover hand and arm function faster after shoulder surgery.
What could go wrong
This is a small, early-stage study with only 60 participants. The PENG block may not provide enough pain relief, or the muscle-sparing benefit may be minimal.
