Double-crossed syndrome" refers to a specific alignment of overactive and underactive muscles in the neck, chest, and shoulders. AIRROSTI stands for Applied Integration for the Rapid Recovery of Soft Tissue Injuries. This study aims to evaluate the effectiveness of Airrosti exercises combined with TheraBand exercises in reducing pain and disability in the neck and shoulders. TheraBand exercise programs are commonly used to improve muscle activation.
