Upper Crossed Syndrome (UCS) is a postural imbalance in the upper body characterized by shortened and tight muscles in the front and upper back, while weak muscles in the back and neck are stretched and underactive. This imbalance can lead to forward head posture, rounded shoulders, and increased spinal curves, causing pain, headaches, and reduced range of motion. The study aims to compare the effects of Kendall exercises with Janda's Approach along with Diaphragmatic breathing exercises on pain, chest expansion, craniovertebral angle, and disability in upper crossed syndrome.
