Shoulder Pain Assessment: Special Tests Every Physiotherapist Should Know

Introduction

Shoulder pain is one of the most common musculoskeletal complaints treated in physiotherapy practice. Due to the shoulder's remarkable mobility and complex anatomy, identifying the exact source of pain can often be challenging. Patients may present with pain during overhead activities, lifting, reaching behind the back, sports participation, or even simple daily activities such as dressing and grooming.

A successful rehabilitation program begins with a systematic and evidence-based clinical assessment. Rather than relying solely on imaging reports, physiotherapists should combine subjective examination, physical assessment, movement analysis, and special tests to determine the underlying pathology and develop an individualized treatment plan.

This comprehensive guide explains the essential assessment process and introduces the most reliable special tests every physiotherapist should know when evaluating patients with shoulder pain.

Understanding Shoulder Anatomy

The shoulder is the most mobile joint in the human body. It consists of multiple joints, muscles, ligaments, tendons, and bursae that work together to provide stability and movement.

The shoulder complex includes:

• Glenohumeral Joint
• Acromioclavicular (AC) Joint
• Sternoclavicular Joint
• Scapulothoracic Articulation

The primary stabilizing structures include:

• Rotator Cuff Muscles
• Glenoid Labrum
• Joint Capsule
• Glenohumeral Ligaments
• Long Head of Biceps Tendon

Because several anatomical structures can produce similar symptoms, a structured assessment is essential for accurate diagnosis.

---

Common Causes of Shoulder Pain

Shoulder pain may arise from muscles, tendons, joints, ligaments, nerves, or referred pain from the cervical spine.

Common conditions include:

• Rotator Cuff Tendinopathy
• Shoulder Impingement Syndrome
• Subacromial Bursitis
• Frozen Shoulder (Adhesive Capsulitis)
• Biceps Tendinitis
• SLAP Lesion
• Acromioclavicular Joint Injury
• Shoulder Instability
• Rotator Cuff Tear
• Calcific Tendinitis
• Glenohumeral Osteoarthritis
• Cervical Radiculopathy (Referred Pain)

---

Why a Structured Shoulder Assessment Matters

A detailed assessment enables physiotherapists to identify the pain-generating structure, determine functional limitations, recognize serious pathology, and select the most appropriate rehabilitation strategy.

A proper assessment helps to:

• Identify the primary source of pain.
• Differentiate between contractile and non-contractile tissues.
• Recognize cervical spine involvement.
• Identify instability and labral injuries.
• Detect rotator cuff pathology.
• Develop individualized treatment goals.
• Monitor rehabilitation progress objectively.

---

Step 1: Patient History

The subjective assessment often provides the most valuable information for diagnosing shoulder disorders. Allow the patient to describe symptoms in their own words before asking focused questions.

Chief Complaint

• When did your shoulder pain begin?
• Did the pain start suddenly or gradually?
• Was there any injury or trauma?
• Which shoulder is affected?

Pain Characteristics

• Pain location
• Pain intensity (VAS/NPRS)
• Sharp, dull, aching, burning, or throbbing pain
• Radiating symptoms
• Night pain
• Morning stiffness

Aggravating Activities

• Overhead reaching
• Lifting objects
• Throwing activities
• Dressing
• Sleeping on the affected shoulder
• Sports activities

Relieving Factors

• Rest
• Medication
• Ice or heat therapy
• Supporting the arm
• Avoiding overhead activities

Previous Medical History

• Previous shoulder injuries
• Previous surgeries
• Diabetes Mellitus
• Rheumatoid Arthritis
• Cervical Spine Disorders
• Previous Physiotherapy

---

Step 2: Red Flag Screening

Before beginning physical examination, physiotherapists must exclude serious pathology that requires urgent medical referral.

Watch for:

• Recent fracture or major trauma
• Unexplained weight loss
• History of cancer
• Persistent fever
• Severe night pain not relieved by rest
• Shoulder deformity
• Progressive neurological deficits
• Signs of infection

---

Step 3: Observation

Observation begins as soon as the patient enters the clinic. A careful visual examination often provides important diagnostic clues before physical testing begins.

Observe the patient during:

• Walking
• Sitting
• Standing
• Removing clothing
• Natural arm swing

Look for:

• Shoulder asymmetry
• Scapular winging
• Rounded shoulders
• Forward head posture
• Muscle wasting
• Swelling
• Bruising
• Deformity
• Protective positioning

---

Step 4: Postural Assessment

Postural abnormalities frequently contribute to chronic shoulder pain by altering scapular mechanics and increasing stress on the rotator cuff.

Assess:

• Head Position
• Cervical Alignment
• Thoracic Kyphosis
• Scapular Position
• Scapular Symmetry
• Shoulder Height
• Clavicle Position

Patients with Forward Head Posture and Rounded Shoulders commonly develop shoulder impingement due to altered scapular movement.

---

Step 5: Pain Assessment

Pain assessment should evaluate both intensity and behavior of symptoms.

Use standardized outcome measures:

• Visual Analogue Scale (VAS)
• Numeric Pain Rating Scale (NPRS)
• Shoulder Pain and Disability Index (SPADI)
• Disabilities of the Arm, Shoulder and Hand (DASH)

Document:

• Pain intensity
• Pain location
• Radiation
• Pain during movement
• Night pain
• Functional limitations

---

Step 6: Range of Motion (ROM) Assessment

Evaluate both active and passive shoulder movements. ROM assessment helps identify capsular restrictions, muscle weakness, pain patterns, and joint dysfunction.

Assess:

• Flexion
• Extension
• Abduction
• Adduction
• Internal Rotation
• External Rotation
• Horizontal Adduction
• Horizontal Abduction

Observe:

• Painful Arc
• Movement Quality
• Compensatory Scapular Movement
• Crepitus
• End Feel
• Movement Restriction

---

Normal Shoulder Range of Motion

Movement	Normal ROM
Flexion	180°
Extension	60°
Abduction	180°
Internal Rotation	70°
External Rotation	90°
Horizontal Adduction	135°

Compare the affected shoulder with the unaffected side and document any restrictions or painful movements.

---

---

Step 7: Palpation

Following observation and range of motion assessment, palpation helps identify localized tenderness, swelling, muscle spasm, trigger points, and injured anatomical structures. Palpation should always be systematic and performed gently while comparing both shoulders.

Palpate the following structures:

• Clavicle
• Acromioclavicular (AC) Joint
• Sternoclavicular Joint
• Coracoid Process
• Greater Tuberosity
• Lesser Tuberosity
• Bicipital Groove
• Subacromial Space
• Scapular Borders
• Upper Trapezius
• Supraspinatus Tendon
• Infraspinatus Muscle
• Teres Minor
• Subscapularis
• Deltoid Muscle

Observe for:

• Localized tenderness
• Muscle spasm
• Joint swelling
• Temperature changes
• Trigger points
• Muscle wasting

---

Step 8: Muscle Strength Assessment

Manual Muscle Testing (MMT) evaluates shoulder muscle performance and identifies weakness associated with rotator cuff injuries, neurological conditions, or pain inhibition.

Movement	Primary Muscle	Nerve
Flexion	Anterior Deltoid	Axillary Nerve
Extension	Latissimus Dorsi	Thoracodorsal Nerve
Abduction	Supraspinatus / Middle Deltoid	Suprascapular / Axillary
Internal Rotation	Subscapularis	Upper & Lower Subscapular
External Rotation	Infraspinatus / Teres Minor	Suprascapular / Axillary

Weakness should always be compared with the opposite side.

---

Step 9: Scapular Assessment

Normal shoulder function depends on coordinated scapular movement. Scapular dyskinesis commonly contributes to impingement syndrome, rotator cuff pathology, and chronic shoulder pain.

Observe during shoulder elevation:

• Scapular Winging
• Early Scapular Elevation
• Scapular Tilting
• Scapular Protraction
• Scapular Retraction
• Scapulohumeral Rhythm

Abnormal scapular mechanics often indicate weakness of the serratus anterior, lower trapezius, or middle trapezius muscles.

---

Step 10: Functional Assessment

Assess how shoulder pain affects the patient's daily activities.

Ask about difficulty performing:

• Combing Hair
• Dressing
• Fastening Bra Behind Back
• Lifting Objects
• Reaching Overhead
• Driving
• Sleeping on the Affected Side
• Sports Activities
• Office Work
• Household Activities
