Humeral Syndromes of the Shoulder: Identify and Treat the 5 Key Classifications

Shoulder pain isn’t one-size-fits-all. Understanding how the humeral head moves in the glenoid allows Physical Therapists to classify dysfunction and target treatment.

Using a Movement System approach, PTs can connect assessment findings directly to interventions.

1. Humeral Anterior Glide (HAG)

Key Features:

• Excessive anterior humeral translation

• Pain with pushing, rowing, dips, or prolonged sitting

Assessment Tips:

• Check forward humeral posture

• Reproduce pain with shoulder extension/pushing

• Test symptom change with posterior humeral reposition

Treatment Strategy:

• Restore glenohumeral centration

• Retrain pushing/pulling mechanics

• Improve posterior cuff and capsule function

  
  

2. Humeral Superior Glide (HSG)

Key Features:

• Superior humeral migration during overhead tasks

• Overhead pain or repeated elevation discomfort

Assessment Tips:

• Painful arc during elevation

• Dominance of deltoid/upper trapezius

• Symptom improvement when unloading shoulder

Treatment Strategy:

• Optimize rotator cuff activation

• Reduce superior humeral glide

• Adjust overhead mechanics and task demands

  
  

3. Humeral Medial Rotation (HMR)

Key Features:

• Excessive internal rotation during movement or exercise

• Pain with lateral raises, lifting, or reaching

Assessment Tips:

• Internal rotation bias during elevation

• Poor external rotation control

• Symptom improvement with humeral reposition

Treatment Strategy:

• Improve external rotation control

• Reduce medial rotation during arm elevation

• Retrain movement quality and posterior cuff function

  
  

4. Glenohumeral Multidirectional Hypermobility (GHMDH)

Key Features:

• Excessive accessory motion with instability-type symptoms

• “Shoulder feels out of place” without true dislocation

Assessment Tips:

• Poor control under load

• Overreliance on global muscles

• Symptom relief with active stabilization

Treatment Strategy:

• Restore dynamic stability

• Improve joint centration

• Train controlled loading and neuromuscular control

  
  

5. Glenohumeral Hypomobility (GHM)

Key Features:

• Limited humeral mobility, affecting functional reach

• Stiffness putting on a belt or reaching behind the back

Assessment Tips:

• Loss of internal rotation/extension

• Posterior stiffness and compensatory movements

• Test symptom improvement with mobilization

Treatment Strategy:

• Restore glenohumeral mobility

• Improve posterior shoulder motion

• Reinforce functional movement patterns

  
  

Clinical Workflow for PTs

1. Observe posture and movement

2. Assess painful task

3. Apply symptom modification procedures

4. Identify symptom changes

5. Treat movement faults, mobility restrictions, or muscle deficits

Outcome: More targeted, movement-based interventions that improve patient function.
