shoulder impingement syndrome. Impingement syndrome of shoulder

Interventions

Intervention 1: Intervention group: Low-load resistance training (LLRT) with Blood Flow Restriction (BFR). Participants in this group will perform exercises at 20-40% of 1RM. An active BFR cuff will b

it will be inflated to a minimal, non-therapeutic pressure to provide the sensory experience without creating meaningful blood flow restriction. This group will also receive standard passive physiothe

Inclusion criteria

Inclusion criteria: Age between 40 to 60 years Literacy in Persian experiencing shoulder pain for a maximum of 3 months Shoulder pain at night or during overhead activities greater than or equal to 3 based on VAS scale Positive Painful arc test and at least three of the following tests: Neer- Hawkins-kennedy- Empty can- infraspinatus

Exclusion criteria

Exclusion criteria: Contraindications for the use of BFR, including:• History of blood clots (DVT)• Blood pressure higher than 180 mmHg• Acute infection, peripheral vascular problems, varicose veins, or cancer.• History of hemorrhagic or thrombotic strokes.• History of arterial fibrillation Simultaneous pain in both shoulders Suffering from frozen shoulder Positive drop arm test indicating a complete rotator cuff tear History of surgery, fracture, or dislocation in the shoulder area Use of anti-inflammatory drugs during the day while undergoing the physiotherapy course

Design outcomes

Primary

Measure	Time frame
Isometric muscle strength of the rotator cuff muscles (supraspinatus). Timepoint: pre and post intervention. Method of measurement: hand-held, fixed dynamometer.	—

Secondary

Measure	Time frame
Thickness of supraspinatus, infraspinatus, middle trapezius, and biceps muscles at rest. Timepoint: pre and post intervention. Method of measurement: B-mode ultrasonography (model: Supersonic MACH30).;Night pain and pain while elevating the shoulder. Timepoint: pre and post intervention. Method of measurement: Numeric pain rating scale.;Pain pressure threshold on 2 points (end of supraspinatus muscle and thenar area of ??the affected side). Timepoint: pre and post intervention. Method of measurement: digital algometer.;Functional pain and disability. Timepoint: pre and post intervention. Method of measurement: Shoulder Pain and Disability Index questionnaire.	—
