The effects of core stabilization training in patients with subacromial impingement syndrome: a single-blind randomized controlled study

PURPOSE: To investigate the effects of core stabilization training (CST), combined with standard rehabilitation, on pain, upper extremity function, shoulder muscle strength, and core stability in patients with subacromial impingement syndrome (SIS). METHODS: Forty-four patients with SIS were randomly assigned to either the core stabilization group (CST + standard rehabilitation) or the control group (standard rehabilitation) and received the interventions for 12 weeks. Primary outcomes were pain and upper extremity function, and secondary outcomes were shoulder muscle strength and core stability parameters. Assessments were performed at baseline and at weeks 3, 6, and 12. RESULTS: > 0.05). CONCLUSIONS: CST combined with standard rehabilitation is effective in reducing pain, improving upper extremity function and core stability in patients with SIS. While it does not provide additional benefits for shoulder muscle strength over standard rehabilitation. CLINICALTRIALS.GOV ID: NCT05966298.
