Movement Impairment Diagnoses Humeral
Criteria:
The primary problem is faulty movement of the humeral head in the GH joint Correction of faulty movement reduces the symptoms The correction of faulty movement reduces symptoms The diagnosis is named for the direction of faulty movement Relationships between alignment and movement
Relationships between alignment and movement
Faulty alignment, normal range of movement but not correct/compensate for faulty alignment Correct humeral alignment, but faulty movement
Normal Alignment of the Humerus
Less than 1/3 of humeral head protruding in front of the acromion Neutral rotation should be present
antecubital crease faces anteriorly Olecranon faces posteriorly
Proximal and distal ends are in the same vertical line
Movement of the Humeral Head
Humeral external rotation is required for:
clearance of the greater tuberosity & soft tissues as it passes under the coracoacromial arch Relaxation of the capsular constraints to allow full elevation
Browne et al., 1990 An et al., 1991
Movement of the Humeral Head
Superior translation 1-3 mm during the first 30-60 scaption1,2,3 due to deltoid activation4 After the initial phase, humeral head stays within the center1,2,3,5,6

Movement of the Humeral Head
Anterior translation ~0.7 2.7 mm during the first 30-60 scaption Posterior translation ~ 1.5 mm 60-90 scaption Posterior translation ~ 4.5 mm 90-120 scaption
Ludewig & Cook, 2002 Eisenhart-Rothe et al., 2002 Graichen et al., 2000
Abnormal Translation of the Humeral Head
Pts with subacromion impingement:
Increased superior translation (~1-1.5 mm)1,2 Increased anterior translation (~3 mm)3
Excessive superior translation also demonstrated in induced fatigue of deltoid and rotator cuff4,5

Humeral Diagnoses
Humeral Anterior Glide Humeral Superior Glide Shoulder Medial Rotation Glenohumeral Hypomobility
Humeral Anterior Glide
Movement Impairment:
Excessive or abnormal anterior movement of the humeral head during shoulder motions
Humeral Anterior Glide
Alignment Faults:
Forward shoulder Greater than 1/3 of the humeral head anterior to acromion Humeral head anterior to the elbow Indentation below the acromion
Humeral Anterior Glide
Impairment of Muscle Length and Recruitment:
Dominant posterior deltoid over infraspinatus and teres minor during external rotation Dominant pectoral major over rotator cuff Long/weak of subscapularis and teres major Short of scapulohumeral lateral rotators and posterior capsule
Humeral Anterior Glide
Confirmation Tests:
Supine medial rotation faulty PICR Prone medial rotation Weak in shortened range Prone lateral rotation anterior glide of humerus Standing shoulder abduction anterior glide of humerus Elbow extension anterior glide of humerus
Humeral Anterior Glide
Pain Problems:
Biceps Tendinitis Anterior GH Impingement Anterior Subluxation/dislocation
Humeral Anterior Glide
Emphasis of Treatment:
Lengthen lateral rotators & posterior capsule Shorter, stronger, stiffer Subscapularis Minimize recruitment of posterior deltoid Correct insufficient upward rotation of the scapula
Humeral Anterior Glide
Treatment Ideas:
Supine medial rotation lengthen lateral rotators & posterior capsule Prone medial rotation - Shorten, strengthen Subscapularis to control PICR Against the wall or supine humeral adduction to stretch posterior capsule Avoid compensatory movement of the scapula Avoid leading with your shoulder Patient education : humeral position relative to elbow
Humeral Superior Glide
Movement Impairment:
Insufficient inferior glide of humeral head during GH flexion/abduction
Humeral Superior Glide
Alignment Faults:
Decreased subacromion space Humerus may be in abduction Scapula is depressed or downward rotated
Humeral Superior Glide
Impairment in muscle lengths and recruitment:
Dominant/short deltoid Dominant pectoralis major/latissimus dorsi over subscapularis Short /or weak infraspinatus, teres minor, and subscapularis
Humeral Superior Glide
Confirming Tests:
Shoulder flexion/abduction in standing Humeral rotation in prone & supine
Weakness or shortness
Lower and Middle Trapezius Strength Supine Pect Major and Latissimus Length Test - Short
Humeral Superior Glide
Pain Problems:
GH impingement Rotator cuff tear Tendinitis, bursitis DJD of GH AC joint pain Frozen shoulder
Humeral Superior Glide
Emphasis of Treatment:
Correcting strength and length of the rotator cuff muscles Decreasing recruitment of the deltoid muscle
Humeral Superior Glide
Treatment Ideas:
Lengthen rotator cuff towel roll Strengthen rotator cuff - prone internal / external rotation Correct scapular position Wall slide - Minimize activation of the deltoid Minimize abduction movement GH flexion with elbow flexed Dont lean on the shoulders
Humeral Medial Rotation
Movement Impairment:
Insufficient lateral humeral rotation during GH flexion/abduction
Humeral Medial Rotation
Alignment Faults:
Medial rotation of humerus in resting position Forward shoulders
Humeral Medial Rotation
Impairment of muscle lengths and recruitment:
Dominance of shortness of medial rotators Long/weak of lateral rotators
Humeral Medial Rotation
Confirmation tests:
Shoulder flexion in standing reduced external rotation Supine shoulder flexion with full external rotation limited, short lats, pect major, teres major Supine and prone external rotation weak lateral rotators
Humeral Medial Rotation
Pain Problems:
GH impingement Tendinitis Bursitis
Humeral Medial Rotation
Emphasis of treatment:
Lengthen lats, pectoralis major, teres major Strengthen infraspinatus & teres minor Minimize GH internal rotation during GH flexion
Humeral Medial Rotation
Treatment Ideas:
Standing shoulder flexion with external rotation Prone external rotation Supine shoulder flexion with fixed scapula to stretch Lats, Pects, Teres Major

Glenohumeral Hypomobility
Movement Impairment:
Limited glenohumeral movement in all directions
Glenohumeral Hypomobility
Impairment of muscle length, strength, and recruitment:
Dominant Deltoid over rotator cuff Dominant Scapulohumeral over axiohumeral muscles Compensatory UT for lack of GH motion
Glenohumeral Hypomobility
Confirming Tests:
Capsular pattern of restriction Short scapulohumeral muscles Weak/long Middle & Lower Trapezius Weak Serratus anterior Weak rotators

Glenohumeral Hypomobility
Pain problems
Frozen shoulder GH impingement Tendinitis/bursitis
Glenohumeral Hypomobility
Emphasis of treatment
Increase GH mobility Promote ideal PICR within available range Minimize scapulothoracic motion before glenohumeral motion has improved Strengthening as range increases BE PATIENT!!!
