Study Overview
Brief Summary
60 healthy participants were randomized into infraspinatus, erector spinae, or gastrocnemius groups. One session of dry needling DN was applied to the muscle in standardized location. Stiffness was assessed using a MyotonPRO at baseline, immediately post DN, and 24 hours later. The presence of a localized twitch response (LTR) during DN was used to subgroup participants.
