Adhesive Capsulitis (Frozen Shoulder) | Part 1 - Presentation & Pathophysiology

The video tutorial explains adhesive capsulitis, commonly known as frozen shoulder, detailing its idiopathic nature, symptoms, and associated conditions. It discusses the causes and effects, including hardening of axillary folds and thickening of the synovial capsule. The tutorial compares range of motion in various shoulder conditions and describes cellular changes and vascularity in adhesive capsulitis. It outlines the four phases of progression: pre-freezing, freezing, frozen, and thawing, emphasizing the gradual onset and long duration of the condition.

What is adhesive capsulitis more commonly known as?

• Bursitis

• Frozen shoulder

• Rotator cuff tear

• Subacromial impingement

Which condition is NOT associated with an increased risk of developing adhesive capsulitis?

• Systemic lupus erythematosus

• Prolonged shoulder immobilization

• Diabetes mellitus

• Hypertension

What is a key physiological change in the shoulder joint due to adhesive capsulitis?

• Increased synovial fluid

• Thickening of the synovial capsule

• Reduction in collagen production

• Expansion of axillary folds

How does adhesive capsulitis affect the range of motion compared to a rotator cuff tear?

• Only passive range of motion is affected

• Only active range of motion is affected

• Both passive and active range of motion are equally affected

• Neither passive nor active range of motion is affected

Which cell type is primarily responsible for increased collagen production in adhesive capsulitis?

• Myofibroblasts

• Osteoblasts

• Fibroblasts

• Lymphocytes

What is the effect of increased vascularity in the shoulder joint during adhesive capsulitis?

• Increased pain perception

• Reduced blood flow

• Decreased inflammation

• Improved range of motion

During which phase of adhesive capsulitis is the range of motion loss non-capsular?

• Thawing

• Frozen

• Freezing

• Pre-freezing

In the frozen phase of adhesive capsulitis, what is a common symptom?

• No pain

• Improved range of motion

• High pain severity

• Low irritability

What happens to the range of motion during the thawing phase of adhesive capsulitis?

• It remains the same

• It gradually returns

• It worsens

• It disappears completely

How long can adhesive capsulitis take to fully resolve?

• 3-6 months

• 6-12 months

• 1-2 years

• 2-3 years
