Background: Shoulder joint has the greatest range of motion so shoulder instability occurs between 10-30% total populations.Objective: The purpose of the study is to investigate the effect of ultrasound therapy along with elastic band over conventional therapy in subjects with anterior shoulder instability. Study Design: Randomized clinical trials.Method: The study is randomized controlled study, the total subjects were ten for each group. The assessment of pain and ROM were taken before starting the treatment of both the groups. The patient were randomly assigned for both the group, assessment were taken on 0 day and 21 day of pain by VAS, ROM by goniometer.Result:The scores of variables VAS and ROM were improved significantly better in the subjects treated with ultrasound therapy and elastic bands.Conclusion: The study concludes that the elastic band exercise in combination with ultrasound therapy is more beneficial than the manual conventional therapy in shoulder instability condition
