Adhesive Capsulitis (Frozen Shoulder): A Chiropractor’s Guide to Diagnosis and Treatment

Shoulder pain can be deceptively complex, but few conditions are as frustrating—for both patient and provider—as adhesive capsulitis, more commonly known as frozen shoulder. Characterized by progressive stiffness, pain, and significant loss of motion, this condition can severely impact daily function and quality of life.

For chiropractors, recognizing the hallmark signs of adhesive capsulitis and implementing a structured, phase-appropriate treatment plan is key to helping patients regain mobility and reduce discomfort.

What Is Adhesive Capsulitis?

Adhesive capsulitis is a condition involving inflammation and fibrosis of the joint capsule of the shoulder, leading to restricted motion in both active and passive ranges. It typically develops gradually and progresses through distinct stages.

Who’s at Risk?

  • Adults between ages 40–65
  • Higher prevalence in women
  • Patients with diabetes or thyroid disorders
  • History of shoulder injury, surgery, or prolonged immobilization

The Three Phases of Frozen Shoulder

Understanding the stage of the condition helps guide treatment decisions.

1. Freezing Phase (Painful Stage)

  • Gradual onset of diffuse shoulder pain
  • Increasing discomfort, especially at night
  • Progressive loss of motion

2. Frozen Phase (Adhesive Stage)

  • Pain may decrease
  • Marked stiffness and limited range of motion
  • Difficulty with overhead or behind-the-back movements

3. Thawing Phase (Recovery Stage)

  • Gradual return of motion
  • Decreasing stiffness
  • Functional improvements over time

Clinical Diagnosis: What to Look For

Adhesive capsulitis is largely a clinical diagnosis, supported by a detailed history and physical examination.

Key Diagnostic Features

  • Global restriction of both active and passive range of motion
  • Capsular pattern limitation (external rotation most limited, followed by abduction and internal rotation)
  • Pain at end ranges of motion
  • No significant findings on imaging (X-rays typically normal)

Differential Diagnoses to Rule Out

  • Rotator cuff tear
  • Shoulder impingement syndrome
  • Osteoarthritis of the glenohumeral joint
  • Cervical radiculopathy

Orthopedic Assessment

While no single orthopedic test definitively diagnoses frozen shoulder, the following findings support it:

  • Passive ROM is as limited as active ROM
  • Firm, leathery end feel with movement
  • Scapular compensation during shoulder elevation
  • Negative or inconclusive special tests for other shoulder pathologies

Chiropractic Treatment Approach

Treatment should be tailored to the stage of the condition, with an emphasis on restoring motion without exacerbating symptoms.

Freezing Phase: Calm the Inflammation

Goals: Reduce pain, maintain as much mobility as possible

  • Gentle joint mobilization 
  • Soft tissue therapy (upper trapezius, levator scapulae, pectorals)
  • Modalities such as heat or low-level laser
  • Patient education on activity modification
  • Pendulum exercises and pain-free range movements

Frozen Phase: Restore Mobility

Goals: Improve joint play and increase range of motion

  • Progressive joint mobilization 
  • Stretching exercises targeting the joint capsule
  • Scapular stabilization exercises
  • Myofascial release techniques
  • Home exercise program emphasizing consistency

Thawing Phase: Rebuild Function

Goals: Normalize movement and strength

  • Functional rehabilitation exercises
  • Resistance training for rotator cuff and scapular stabilizers
  • Proprioceptive and coordination training
  • Continued mobility work to prevent regression

Final Thoughts

Adhesive capsulitis can be a long and challenging condition, but with accurate diagnosis and a phase-specific chiropractic approach, patients can achieve meaningful improvements in pain and mobility. The key lies in recognizing where the patient is in the progression of the condition and adjusting care accordingly.

With patience, consistency, and the right strategy, frozen shoulder doesn’t have to stay frozen forever.
