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.

Conditions

Shoulder Impingement Syndrome

Keywords

Blood flow restriction/ shoulder impingement syndrome

Outcome Measures

Primary Outcomes (1)

• Muscle strength

  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

  20 minutes

Secondary Outcomes (3)

• Functional assessment

  20 minutes

• Pain assessment

  15 minutes

• Range of motion

  20 minutes

Interventions

Blood Flow Restriction training OTHER

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

Concentric; Eccentric; Isometric

Eligibility Criteria

• Age: 30 Years - 40 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• 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

You may not qualify if:

• Large, full-thickness rotator cuff tear, Moderate, severe glenohumeral or acromioclavicular joint osteoarthritis. - Glenohumeral joint instability including previous shoulder dislocation/subluxation. - Previous shoulder fracture. - Current neck pain/dysfunction with a somatic or radicular referral pattern indicative of cervical spine rather than shoulder as primary source of symptoms and/or pathology. - Neurological deficits of the upper limb. - Systemic inflammatory arthritic conditions (Fatima et al., 2021).
