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.

Interventions

OTHERBlood 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

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

Exclusion criteria

* 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).

Design outcomes

Primary

MeasureTime frameDescription
Muscle strength20 minutesAll 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

MeasureTime frameDescription
Functional assessment20 minutesBy DASH questionnaire
Pain assessment15 minutesBy visual analogue scale
Range of motion20 minutesBy bubble inclinometer
