Clinical Trial 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.

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.

Eligibility

Inclusion criteria:

Age range 30-40 years. - Pain localized to the proximal anterolateral shoulder region, - Positive for pain on at least one of the following three impingement tests: Hawkins-Kennedy, Neers, Jobes and Positive for pain on at least one of the following four tests: Painful arc, drop arm test, lift off test, and resisted external rotation (Fatima et al., 2021

Intervention

Other:
• Blood Flow Restriction training
It is a method that involves reducing blood flow to a muscle by the application of an external constricting device, such as a blood pressure cuff or tourniquet, to provide mechanical compression of the underlying blood vessels. BFR is applied aiming to enhance blood pooling in the capillary beds of the limb muscles distal to the tourniquet

Secondary	Functional assessment	By DASH questionnaire	20 minutes
Secondary	Pain assessment	By visual analogue scale	15 minutes
Secondary	Range of motion	By bubble inclinometer	20 minutes
