Introduction[edit | edit source]

Subjective[edit | edit source]

Patient Intake[edit | edit source]

Taking a detailed patient history is important. Listen carefully to the patient’s past medical history (PMHx) and history of presenting condition (Hx PC). The narrative given by the patient contains much of the information needed to rule out red flags and guide the shoulder examination.

The patient may report pain local to the involved shoulder. The symptoms may extend toward the scapula, axilla, anterior chest, along the clavicle, or down the humerus. When taking the patients history it is also important to ask if they have pain or symptoms in other regions such as their cervical or thoracic spine, or elbow. The patient may also report difficulty with overhead activities, lifting objects, activities of daily living, sports or recreational activities. There are several presentations that may differ depending on the suspected pathology.

  • Patients with suspected glenohumeral instability or labral pathology may have feelings of “looseness or instability” particularly in abducted and externally rotated positions. 
  • Patients with suspected adhesive capsulitis may report intense global shoulder pain initially combined with a progressive loss of range of motion. 
  • Patients with suspected subacromial impingement or rotator cuff impairment may report feelings of weakness, heaviness and/or pain.


Shoulder History Exam Questions: These questions may assist the clinician in determining potential pathologies. Please refer to the User's Guide to Musculoskeletal Examination[1]  for more information.

  1. Does moving your neck change your symptoms?
  2. Do you ever feel unstable during arm movement?
  3. When you do actions with your arms over your head, does this aggravate your pain level?
  4. Is it difficult to move your arm? 
  5. When performing actions with your arms over your head, do your arms feel heavier?

Outcome Measures[edit | edit source]

  • Shoulder Pain and Disability Index (SPADI)
  • Disabilities of the Arm Shoulder and Hand (DASH)
  • American Shoulder and Elbow Surgeons Self-Report (ASES)
  • Extremity Disability Index
  • Simple Shoulder Test (SST)
  • Constant-Murley Shoulder Outcome Score (CMS)
  • University of Pennsylvania Shoulder Score (U-Penn)

Special Questions[edit | edit source]

Patients with shoulder pain should be questioned for the presence of red or yellow flags. A thorough medical history and possibly the use of a medical screening form is the initial step in the screening process. The chart below highlights some of the most common red flag conditions for patients with shoulder pain.

Red Flags[edit | edit source]

Determine if patient's symptoms are reflective of a visceral disorder or a serious potential life-threatening illness such as cancer, visceral pathology or fracture.[2]

Potential Shoulder Regional Referral Patterns:

Left Shoulder

  • MI 68.7% of patients reported shoulder pain during an acute myocardial infarction[3]
  • Ruptured Spleen[4]

Both Shoulders

  • Pancoast’s Tumor[5]

Right Shoulder

  • Liver Disease[6]
  • Carcinoma,Cirrhosis, Hepatitis
  • Stomach
  • Hiatal Hernia[7]
  • Post Bariatric Surgery
  • Gastric Perforation[8]
  • Peptic Ulcer
  • Pancreas
  • Pancreatitis
  • Pancreatic Cancer
    • May be worse after fatty meal or associated with eight loss of Diabetes Mellitus
  • Gall Bladder
  • Cholecystitis
    • Typically accompanied by fever, or nausea/vomiting

Fractures

Fractures may result from trauma such as falls onto an outstretched hand. These are known as FOOSH injuries.

  • Commonly fractured both within the shoulder region
  • Humeral Fractures
    • Proximal or distal
  • Clavicle Fractures[9]
    • Fractures of the clavicle usually result from a direct blow to the shoulder giving axial compression. The middle 1/3 of the clavicle is most often broken with an incidence of ~80%. Distal clavicle fractures have an incidence of 10-15% and medial clavicle fractures have and incidence of 3 to 5%. Significantly displaced fractures are managed surgically.Mid-shaft clavicle fractures have a lower rate of mal-union and better functional outcomes at one year.[10] A trial of conservative management may be warranted for non-displaced clavicular fractures.

Yellow Flags[edit | edit source]

Yellow flags are factors that increase a patient’s risk for developing long-term disability.

Psychosocial Factors may be contributing to a patient’s persistent pain and disability, or that may contribute to the transition of an acute condition to a chronic, disabling condition. Some attitudes and beliefs to look out for are: [11]

  • Pain is harmful or disabling
  • Pain must be eliminated before returning to activity
  • Passive attitudes towards therapy
  • Patient utilization of extended rest, reduced activity level and withdrawal from daily activities
  • Patient reports of extreme pain intensity
  • High intake of alcohol or other substances

The Fear Avoidance Belief Questionnaire (FABQ) is a tool to assess yellow flags among patients. The FABQ predictive validity is debatable, and is best for the FABQ-W when evaluating workers compensation patients.  The overall test-retest reliability is excellent, ICC= .97.

Depression Screening tools such as the Beck Depression Inventory (BDI) or the Depression Anxiety Screening Scale (DASS) are useful in screening patients for depression. Psychometric properties of the BDI: a cut-off score of ≥5 for screening, Sn = 90.9%, Sp = 17.6 %. A cut-off score of ≥22 for diagnostic utility, Sn = 27.3%, Sp = 90%.

The Pain Catastrophizing Scale, helps determine if the patient is exaggerating their pain and symptoms and the severity of the situations as a whole. Cronbach alpha values reported for the total Pain Catastrophizing Scale (PCS) (α=.87) and factor scales (Rumination α=.87; Magnification α=.60; Helplessness α=.87) were found to be satisfactory. The total PCS score showed strong temporal validity [12]. In a patient population with acute whiplash there was found to be a significant moderate correlation between pain pressure threshold and the pain catastrophizing scale as well as cold pain threshold and the pain catastrophizing scale [13].

Clear the Cervical Spine

The cervical spine can refer pain to the shoulder/scapular region. It is imperative that the cervical spine be screened appropriately as it may be contributing to the patient’s clinical presentation.

See Cervical Examination

Investigations[edit | edit source]

Radiographs of the shoulder can be used to identify cysts, sclerosis, or acromial spurs, osteoarthritis of the acromioclavicular and glenohumeral joint, or calcific tendonitis.

Common radiographic views may include (this may vary depending on medical provider):

  • Supraspinatus Outlet View
  • Scapular Y-View
  • Axillary View
  • Anterior-Posterior (AP) View

Objective[edit | edit source]

Observation[edit | edit source]

Observation of a patient with a primary complaint of shoulder pain may include:

  • Static Postures
  • Static Scapular Position
  • Cervico-thoracic spine postures
  • Dynamic movement patterns
  • Scapulo-humeral rhythm
  • Functional tests
  • Hand behind head
  • Hand behind back
  • Cross body adduction
[14]
[15]
[16]
[17]

Palpation[edit | edit source]

Palpation of the shoulder region may provider the physical therapist with valuable information. The physical therapist should note the presence of swelling, texture, and temperature of the tissue.

Additionally the physical therapist may observe asymmetry, sensation differences, and pain reproduction.

Key palpable structures include:

  • Acromioclavicular joint
  • Sternoclavicular joint
  • Rotator cuff muscle insertions
  • Long head of the biceps tendon

Neurologic Assessment[edit | edit source]

A comprehensive neurological examination may be warranted in patients that present with a primary complaint of shoulder pain. The presence of neurological symptoms including numbness and tingling may warrant this examination.


Screening Examination

  • C4 – Shoulder Elevation/Shrug
  • C5 – Shoulder Abduction
  • C6 – Elbow Flexion, Wrist Extension
  • C7 – Elbow Extension, Wrist Flexion
  • C8 – Thumb Abduction/Extension
  • T1 – Finger Abduction

Dermatomes

  • C4 – Top of Shoulders
  • C5 – Lateral Deltoid
  • C6 – Tip of Thumb
  • C7 – Distal middle Finger
  • C8 – Distal 5th Finger
  • T1 – Medial Forearm

Pathological Reflexes

  • Hoffman’s Reflex
  • Inverted Supinator Reflex

Deep Tendon Reflexes

  • Biceps Brachii – C5 Nerve Root
  • Brachioradialis – C6 Nerve Root
  • Triceps – C7 Nerve Root
