The Frozen Shoulder Three-Phase Progression: Understanding Adhesive Capsulitis

What is Adhesive Capsulitis?

Adhesive capsulitis, commonly known as frozen shoulder, is a condition that causes stiffness, pain, and limited range of motion in the shoulder joint. It typically progresses through three distinct phases: freezing, frozen, and thawing.

During these phases, the shoulder capsule becomes inflamed and thickened, leading to significant discomfort and reduced mobility.

The Three Phases Explained

In the freezing phase, patients experience increasing pain and stiffness. This phase can last from six weeks to nine months.

The frozen phase is characterized by severe stiffness and limited range of motion that persists for several months, often up to a year.

Why Does It Matter?

Understanding the three-phase progression helps in managing the condition more effectively. Early recognition can lead to timely interventions such as physical therapy and pain management strategies.

The knowledge of these phases also aids healthcare providers in predicting recovery timelines and tailoring treatment plans.

Real-World Examples

Adhesive capsulitis is a common condition, affecting about 2% to 3% of the general population. It can occur at any age but is more prevalent in individuals aged 40 to 60 years.

The condition often affects people with diabetes and those who have undergone shoulder surgery.
