Methods: Eleven students (mean age Z 19 AE 2.17 years old) from the University of Santo Tomas e College of Rehabilitation Sciences were involved in a 3-week study comparing the effects of the STEP protocol with a conventional strengthening program for anterior shoulder instability. The subjects were screened with special tests, X-ray, and were randomly assigned to experimental and control groups. Both groups received a 3-week program with different sets of exercises.

... e acquired by having the subjects answer the Western Ontario Shoulder Instability Index (WOSI) and the Quick-DASH. Results: Independent t-tests show that subjects were homogenous at baseline. Results show that there were no significant differences within and between the two groups. However, clinical improvements were seen in the two groups based on their pre and posttest scores, with the experimental group exhibiting more improvement than the control group. Conclusion: There was no statistical difference between the STEP protocol and conventional strengthening program in treating individuals with anterior shoulder instability. Also, proper dosage, repetitions, and type of stimulation during exercise are important in recovery of patients with shoulder instability, which was seen in the greater clinical improvement of the STEP group than of the conventional group. http://dx.
