Effects of Low- Load Strengthening Using Different Exercises Modes During Blood Flow Restriction for Treating Shoulder Impingement Syndrome

Not Applicable

Completed

• Conditions: Shoulder Impingement Syndrome
• Interventions: Other: Blood Flow Restriction training

• Registration Number: NCT05695820
• Lead Sponsor: Cairo University

Brief Summary

Purpose of the study: This study compares effects of isometric, concentric and eccentric exercises for shoulder muscles by using low load blood flow restriction training on pain, strength and function in patients with SIS.

Detailed Description

This study will be conducted at El hadra university hospital, Alexandria, Egypt. Study Design: Randomized Parallel Groups Clinical Trial. Participants: Sixty patients of both genders with unilateral shoulder impingement syndrome, with age range from 30-40 years will be randomly assigned to 1 of 3 groups. All patients will be referred by the orthopedic surgeon who will diagnose shoulder impingement syndrome based on clinical and radiological examination. Group 1: twenty patients will receive concentric training of rotator cuff muscles while applying blood flow restriction for 4 weeks. Group 2: twenty patients will receive eccentric training of rotator cuff muscles while applying blood flow restriction for 4 weeks. Group 3: twenty patients will receive isometric training of rotator cuff muscles while applying blood flow restriction for 4 weeks. The assessment for all groups will be done at baseline and after 4 weeks.

Primary Outcome Measures

Name	Time	Method
Muscle strength	20 minutes	All HHD assessments will be done in the form of three trials of 3 seconds of maximal isometric contraction and a 10-second rest period between each measurement. The mean peak force, will be recorded in kilograms (Kgs), and used as the strength measure

Secondary Outcome Measures
