Effects of Low-Load Exercise on Postneedling-Induced Pain After Dry Needling of Active Trigger Point in Individuals With Subacromial Pain Syndrome.

Background: The application of dry needling usually is associated with postneedling-induced pain. A postneedling intervention to reduce this adverse event is needed.

Objective: To determine the effectiveness of low-load exercise on reducing postneedling-induced pain after dry needling of active trigger points (TrPs) in the infraspinatus muscle in subacromial pain syndrome.
