Scapulohumeral Rhythm = ?
All Things Scapula
Scapulohumeral Rhythm:
Normal Scapular mechanics = ?
All Things Scapula
Normal Scapular mechanics:
Active Movements = ?
All Things Scapula
Active Movements:
- We want symmetrical motion that matches the relative movement of the humerus without winging or tilting.
- We want to see the scapula move up and not be fixated
- Watch the movement, especially of the scapula, in the ascending and descending phases of abduction.
- Commonly, weakness of the scapular control muscles is more evident during descent, and an instability jog, hitch, or jump may occur when the patient loses control of the scapula.
SICK Scapula:
- What is it = ?
- Signs & Symptoms = ?
All Things Scapula
SICK Scapula:
- Scapular Malposition
- Inferior Medial Prominence
- Coracoid Pain
- Dyskinesis movement
Scapular Dyskinesia
All Things Scapula
Scapular Dyskinesia:
- Abnormal movements of the shoulder blade. Also sometimes called “Sick Scapular Syndrome.”
- Variety of causes most of which are attributed to errors in timing and rhythm of muscular activations .
Scapular Winging:
- Primary = ?
- Secondary = ?
- Dynamic = ?
All Things Scapula
Scapular Winging:
(a) Primary scapular winging:
- Due to muscle weakness of one of the scapular muscle stabilizers.
(b) Secondary scapular winging:
- Normal movement of scapula is altered because of pathology in glenohumeral joint.
(c) Dynamic scapular winging:
- May be due to lesion of the long thoracic nerve affecting serratus anterior, trapezius palsy (spinal accessory nerve), rhomboid weakness, multidirectional instability, voluntary action, or a painful shoulder resulting in splinting of the glenohumeral joint, which in turn causes reverse scapulohumeral rhythm.
Describe the quality of the movement in the scapula = ?
All Things Scapula
Quality of the movement in the Scapula:
- Does it have a Dysrhythmia?
- Asymmetry?
- Does it have a sudden jerk or position change?
- At what position of shoulder elevation does it display winging or medial prominence
- Is the dyskinesia noted more during concentric or eccentric activities.
Causes of Scapular Imbalance Patterns = ?
All Things Scapula
Scapular Imbalance Patterns:
(a) Increased protraction:
- Tight pectoralis minor
- Weak/lengthened lower trapezuis
- Weak/lengthened serratus anterior
(b) Increased depression:
- Weak upper trapezuis
(c) Loss of scapular stabilization:
- Early/excessive protraction
- Early/excessive lateral rotation of scapula
- Early/excessive elevation of the scapula
- Tight lateral rotators
- Secondary impingement
Scapular winging faults = ?
All Things Scapula
Scapular Winging Faults:
(a) On concencentric elevation:
- Long/weak serratus anterior
(b) On eccentric forward flexion:
- Overactive rotator cuff
- Underactive scapular control muscles
(c) Tilting of inferior angle:
* Tight pectorlis minor

Tests for Scapular Movement Dysfunction include = ?
All Things Scapula
Tests for Scapular Movement Dysfunction include:
- Static Measurements of Scapular positioning
- Scapular assistance test
- Scapular retraction test
- Wall pushup test
Three static (postural) measurements of scapular dysfunction = ?
All Things Scapula
Three static (postural) measurements of scapular dysfunction:
- Inferiority of superior medial scapular angle compared to the opposite side.
- Lateral displacement measured from the superior medial scapular angle from spine.
- Abduction of the medial boarder in degrees from vertical vs the measurement of the opposing side.
Scapular Assistance Test = ?
All Things Scapula
Scapular Assistance Test:
- Have the patient perform forward flexion/elevation.
- Compare that unassisted movement to an assisted movement
- The examiner assist the patient by promoting normal scapular mechanics by stabilizing the upper scapular border and assisting upward rotation of the inferomedial border.
- If the patient has less pain with flexion this is which is diagnostic for scapular dyskinesis
Wall Pushup Test = ?
All Things Scapula
Wall Pushup Test:
- Patient does 10-15 pushups. Winging will most likely show up within the first 5-10 reps.
- Quality of movement or the presences of scapular dyskinesia is noted.
Scapular Rehab:
- Realize in most cases scapular rehab is utilized to address = ?
- Try to normalize = ?
- Address the = ?
All Things Scapula
Scapular Rehab:
(a) Realize in most cases scapular rehab is utilized to address other pathologies (i.e. labral, RTC tears, impingement etc.) rather than scapular dyskinesia in isolation.
(b) Try to normalize rhythms so they are symmetrical.
(c) Address the deficits:
- medial boarder winging needs serratus strengthening
- anterior tilting needs pec minor stretching
- Excessive abducted scapula needs mid and low trap strengthening
- Downward rotated scapula need upper trap strengthening
(d) Don’t expect abnormal motor patterns to go away quickly. They take proper cueing and good kinesthetic awareness to correct.
(e) The scapula needs to move sufficiently and smoothly and have sufficient muscular support.
Rehab Ideas
- Address the hardware
- Address the software
- Stretch pecs & strengthen traps and serratus etc.
- Retrain movements for better motor control.
