Scapulothoracic Joint - Elevation

Elevation of the Scapula is one of several movements available to the Scapulothoracic Joint that involves superior gliding of the Scapula with a compliment of Sternoclavicular Joint and Acromioclavicular Joint rotations. In layman’s terms this movement describes the raising or “ Shrug ging” of the Scapula relative to the Thorax . This motion performed against resistance also forms a basis for evaluating Cranial Nerve XI or the C4 Myotomes .

Kinematics

Elevation at the Scapulothoracic Joint occurs as the Scapula glides superiorly, guided by the fixed path of the Clavicle at the Sternoclavicular Joint where it rolls superiorly about an anteroposterior axis while gliding inferiorly on the joints articular disc (SOURCE-2). At the opposing (lateral) end of the Clavicle , the Acromioclavicular Joint makes subtle downward rotational adjustments which allows the Scapula to remain vertical throughout Elevation (SOURCE-7). These understated movements at the other joints allow the Scapula to remain flush with the Thorax (SOURCE-7). A resting posture of slight Elevation and Scapulothoracic Joint - Retraction is considered an optimal position for The Shoulder Girdle as it leaves the Glenoid Fossa facing slightly upwards (SOURCE-7).

Motion is facilitated primarily by the Trapezius which contracts on the lateral Clavicle , Acromion and Spine of Scapula to draw them superiorly (SOURCE-2+6+7). Contribution from the Levator Scapulae aids in lifting the Scapula and offsets some of the upwards rotation bias produced by the Trapezius (SOURCE-2). To a lesser extent, the Rhomboids also elevate the Scapula and play a more significant role in the maintenance of its stability throughout movement (SOURCE-6+7).


Pathomechanics

Both prime movers have the capacity to compensate for one and other in the presence of insufficiency (SOURCE-3). However, given the Scapulothoracic Joint - Upward Rotation bias of the Upper Trapezius and Scapulothoracic Joint - Downward Rotation bias of the Levator Scapulae , compensation often results in a failure to neutralise these rotations during arm elevation (SOURCE-2).

Like many shoulder movements, Elevation of the Scapula may be subject to Posterior Glenohumeral Joint Capsule tightness may restrict movement and predispose Subacromial Impingement during arm elevation (SOURCE-6). Similarly, hypertonicity of the Subclavius or restriction in the Costoclavicular Ligament or Sternoclavicular Joint Capsule have the capacity to restrict the necessary superior roll/inferior glide of the Clavicle at the Sternoclavicular Joint which may limit the available Elevation range (SOURCE-2).

Premature or excessive Elevation suggests a loss of Scapula stabilisers such as the Serratus Anterior and/or restriction of the Glenohumeral Joint (SOURCE-1+6). This causes the axis of rotation for the Glenohumeral Joint to migrate superiorly which may predispose Subacromial Impingement (SOURCE-12). Excessive Elevation is also associated with mouth- Breathing in children (SOURCE-1).

As the Trapezius plays an integral role in the maintenance of an upwards facing Glenoid Fossa posture, insufficiency and a consequent reduction in Elevation may have wide-spread implications for The Shoulder Girdle at rest and through movement (SOURCE-7). While injury may be caused to the Trapezius through blunt trauma, like those described in more severe forms of Acromioclavicular Joint Dislocation , insufficiency is most often attributed iatrogenic injury to Cranial Nerve XI from surgical procedures that involve thePosterior Cervical Triangle(SOURCE-13+14).


Pathology

As detailed underPathomechanics, distubance to the intricate balance between each Scapula Elevator and the related stabilisers may be attributed to several causes and predispose several pathologies of The Shoulder Girdle .

Scapular Dyskinesis - both an increase and decrease in Scapula Elevation are considered Dyskinetic patterns. Increased Elevation of the Scapula is a common compensatory response to Glenohumeral Joint restriction which may result from many pathological states including Adhesive Capsulitis , Subacromial Impingement and Pain avoidance/ movement apprehension. Ironically, both increased and decreased Elevation of the Scapula are considered notable predisposing factors for Subacromial Impingement , though through diverging mechanisms (SOURCE-4+6+12).

Cranial Nerve XI Palsy - the most common cause of Upper Trapezius insufficiency may result from blunt trauma, such as those described in more severe forms of Acromioclavicular Joint Dislocation , or more commonly represent a complication of surgical procedures that involve thePosterior Cervical Triangle(SOURCE-13+14).

Thoracic Spine Kyphosis - an excessive Thoracic - Flexion posture is associated with a significant loss of Scapulothoracic Elevation (SOURCE-4).


Assessment

Observation

Range of Motion

Elevation of the Scapula is rarely assessed in isolation and more often evaluated as a composite motion of The Shoulder Girdle or determined by the resting position of the Scapula . With that said, approximately 35-40º of active Elevation should be available to the Scapulothoracic Joint (SOURCE-11). While this movement is often evaluated seated with arms in slight GH Joint - Abduction and 90º Elbow - Flexion , it may also be performed in prone to diminish the effects of gravity (SOURCE-5). In terms of Isometric Tests , active-resisted Elevation also doubles as the motor assessment for Cranial Nerve XI and the C4 Nerve Root .

Neurological Tests

The following tests may be conducted to rule in/out nerve contribution with C5 , C6 , C7 , C8 and T1 Nerve Roots mst relevant to Scapulothoracic Joint Depression: Cervical - Myotomes (active resisted)

Cervical - Dermatomes - evaluates sensory region

  • C3 - skin over the posterior neck, superior shoulder and Clavicle

  • C4 - skin over the superior shoulder and upper Chest

  • C5 - skin over the lateral shoulder/ Deltoid towards base of Thumb


Treatment

The treatment of Scapulothoracic Joint Elevation dysfunction should be specific to the underlying cause. For rehabilitation of common underlying conditions such as Scapular Dyskinesis , Subacromial Impingement or Glenohumeral Joint restriction, see their respective pages.

Stretching

The following Stretching techniques may directly or indirectly improve Scapulothoracic Joint Elevation restriction:

Strengthening

As a specific training protocol relates to the underlying cause of Scapulothoracic Joint Elevation dysfunction, the following lists elevation-based Strength exercises in rough descending order from most rudimentary:

Mobilisation

The following Mobilisation techniques may be relevant in the treatment of Scapulothoracic Joint Elevation: Joint Play

Mobilisation with Movement - mobilisations applied with active movement
