New shot methods aim to take the ouch out of injections
NCT ID NCT07262463
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two ways of giving a muscle injection—Manual Pressure and Traction-Pressure-Release (TPR)—to see if they hurt less than the usual method. 174 adults getting a common painkiller shot rated their pain and satisfaction right after. The goal was to find a simple technique that makes injections more comfortable.
