BACKGROUND: Upper cross syndrome (UCS) is a muscle imbalance caused by a postural problem. This needs correction to improve the posture and help to regain muscle strength. Scapular stabilization exercises are the exercises that positively help to prevent UCS. AIM: The purpose of the study was to investigate if there was a difference in the effect of percussion gun and scapular stabilization exercises versus only scapular stabilization exercises in participants with UCS within the age group of 19 to 25 years. SETTINGS AND STUDY DESIGN: A randomized controlled trial was conducted on collegiate students between the age group of 19 to 25 years. METHODOLOGY: Individuals with UCS (n = 40) were randomly allocated to experimental (Group A) and control groups (Group B). Participants in the experimental group were treated with percussion gun and scapular stabilization exercises, while participants in the control group were given only scapular stabilization exercises. Outcome measures used were craniovertebral angle (CVA), shoulder angle (SHA), cervical range of motion (ROM), and the strength of cervical flexors, which were assessed. RESULTS: Participants in both the groups showed a significant improvement in CVA, SHA, cervical ROM, and strength of cervical flexors. However, the experimental group revealed a more significant increase in CVA, SHA, cervical ROM, and strength of cervical flexors than the control group. CONCLUSION: Both the experimental and control groups have shown improvements in ROM, CVA, SHA, and muscle strength. However, the study concluded that the percussion gun, along with scapular stabilization exercises, revealed better results than only scapular stabilization exercises.
