Shoulder Movement Coordination Deficits
ICD-9-CM codes : 840.2 Shoulder ligament sprain 840.0 Acromioclavicular joint sprain
ICF codes : Activities and Participation Domain codes: d4305 Putting down objects (Using hands, arms or other parts of the body to place an object down on a surface or place, such as when lowering a container of water to the ground.) d4451 Pushing (Using fingers, hands and arms to move something from oneself, or to move it from place to place, such as when pushing an animal away.) d4452 Reaching (Using the hands and arms to extend outwards and touch and grasp something, such as when reaching across a table or desk for a book.) d4300 Throwing (Using fingers, hands and arms to lift something and propel it with some force through the air, such as when tossing a ball.) d4550 Crawling (Moving the whole body in a prone position from one place to another on hands, or hands and arms, and knees.) d4551 Climbing (Moving the whole body upwards or downwards, over surfaces of objects, such as climbing steps, rocks, ladders of stairs, curbs or other objects.) Body Structure code: s7203 Ligaments and fasciae of shoulder region Body Functions code: b7601 Control of complex voluntary movements
Common Historical Findings
Glenohumeral ligaments and fasciae involvement : Shoulder pain during activity - aching afterwards Recurrent subluxations or dislocations with certain movements, positions, and activities Apprehension
Acromioclavicular ligaments and fasciae involvement : Trauma--a fall on the tip of the shoulder or a fall onto an outstretched arm Pain with reaching across body, with overhead activities and with weight bearing on elbows or sleeping on the injured shoulder
Common Impairment Findings - Related to the Reported Activity Limitation or Participation Restrictions:
Glenohumeral ligaments and fasciae involvement : Excessive glenohumeral accessory motion Apprehension at end range elevation, horizontal abduction, and external rotation (if anterior instability)
Acromioclavicular ligaments and fasciae involvement : If Grade II or III sprain - palpable and observable displacement between the clavicular and acromial articular surfaces Pain with accessory movement tests Pain with palpation/provocation of acromioclavicular ligament
Physical Examination Procedures :
Glenohumeral Accessory Movement Test Humeral Posterior Glide
Performance Cues: Patient sits on end of table Ensure “loose packed position” Do not elevate scapula Allow the patient’s wrist to rest on your elbow Stabilize spine of scapula with palm Glide humerus (and thus, humeral head) posteriolaterally - in a direction parallel to the plane of the glenoid fossa OK to use weight shift of thorax to produce glide
Glenohumeral Accessory Movement Test Humeral Anterior Glide
Glenohumeral Accessory Movement Test Humeral Anterior Glide
dynamic stability is provided by the muscular action of the supraspinatus, infraspinatus, subscapularis, and deltoid muscles along with the tendon of the longhead of the biceps. Classification of Glenohumeral Instability is derived from four factors:
- Frequency (acute, recurrent, chronic)
- Causes (traumatic, atraumatic including voluntary, repeated micro trauma)
- Direction (anterior, posterior, inferior, multidirectional)
- Degree (subluxation, dislocation)
Acute Stage / Severe Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions code : b7601.3 SEVERE impairment of motor control/coordination of complex voluntary movements
- Patients with a recent ligament injury typically try to support the arm with opposite extremity and avoid using the injured arm
- Active shoulder movements are restricted and painful
- Passive and accessory movement testing reveals hypermobility of the glenohumeral joint Note: The direction of laxity typically corresponds to the label given to the instability (e.g., excessive anterior glide corresponds with an anterior instability)
- Positive apprehension (Crank) test
- Supraspinatus and infraspinatus weakness is common
- Palpatory abnormalities may be present (e.g., with an anterior instability the humeral head may palpable anteriorly and shows a hallow beneath the acromion posteriorly.
- Axillary nerve injury is most commonly associated with an anterior shoulder dislocation leading to altered sensation in an area of the lateral shoulder
Sub Acute Stage / Moderate Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions code : b7601.2 MODERATE impairment of motor control/coordination of complex voluntary movements
As above with the following differences:
- Weakness is common to the dynamic stabilizers such as scapular upward rotators (trapezius, serratus anterior, rhomboids, and levator scapulae), and rotator cuff musculature (supraspinatus, infraspinatus, teres minor, and subscapularis) with contractions at end range of movement
- Now (when less acute) examine patient for co-existing upper quadrant impairments, such as upper thoracic and cervical pathologies, disorders of the acromioclavicular and sternoclavicular joints, muscle flexibility deficits such as tight pectoralis minor, pectoralis major, and/or serratus anterior and muscle strength deficits especially of the rotator cuff muscles and scapular upward rotators
Settled Stage / Mild Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions code : b7601.1 MILD impairment of motor control/coordination of complex voluntary movements
As above with the following differences:
- Shoulder symptoms are reproduced with repeated movements at end range
Intervention Approaches / Strategies
Acute Stage / Severe Condition:
Goals: Prevent further tissue damage Re-establish non-painful mid-range mobility and avoid unstable positions with the involved shoulder Retard muscle atrophy Decrease pain and inflammation
- Physical Agents Ice pack or ice massage Electrical stimulation
- External Devices (Taping/Splinting/Orthotics) Application of a shoulder sling may reduce pain, protect the joint from futher injury and prevent excessive muscle guarding following a glenohumeral ligament injury
- Therapeutic Exercises Pendulum and wand exercises in painfree, mid ranges Isometric rotator cuff exercises in painfree, mid ranges
- Re-injury Prevention Instruction: Temporarily limit abduction, flexion, lateral rotation and overhead activities or behind back activities that aggravate patient's symptoms.
Sub Acute Stage / Moderate Condition
Goals: As above Regain and improve muscular strength and endurance Regain and improve proprioception and neuromuscular control
- Therapeutic Exercises Strengthening exercises for the dynamic stabilizers such as rotator cuff and scapular muscles in order to increase stability with pain free active movements at mid as well as end ranges Upper body endurance can improved through use of mid range aerobic exercises such as rowing machines or upper body ergometers
- External Devices (Taping/Splinting/Orthotics)
- Approaches / Strategies listed above

Shoulder Stability Deficits: Description, Etiology, Stages, and Intervention Strategies
The below description is consistent with descriptions of clinical patterns associated with the vernacular term “ Acromioclavicular Instability ”
Description: Disruption of the ligamentous integrity of the acromioclavicular (also called A/C) joint. The acromioclavicular ligament may be damaged with excessive posteriorly directed translatory or rotatory force. The coracoclavicular ligaments (conoid and trapezoid) may be damaged with excessive superiorly or anteriorly directed forces.
Etiology: The cause of this injury is generally a traumatic incident such as a fall directly on the shoulder with the arm adducted or a fall on an outstretched hand.
Acute Stage / Severe Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions codes : b7150.3 SEVERE impairments of stability of a single joint
- Protective posturing (e.g., cradling the arm and stabilizing it against the body)
- Variable elevation of the distal clavicle relative to the acromion
- Pain limited active shoulder flexion
- Pain with reaching across the body (horizontal abduction)
- Weak and painful with resisted shoulder flexion and shoulder abducton
- Tenderness to palpation over the acromioclavicular joint
- Symptoms reproduced with palpation or provocation of the A/C ligament
- Localized swelling around the joint
- Positive A/C compression or shear tests
Sub Acute / Moderate Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions codes : b7150.3 MODERATE impairments of stability of a single joint
As above with the following differences:
- Pain with overhead activities
- Resisted shoulder flexion and abduction are now strong and painful
Settled Stage / Mild Condition: Physical Examinations Findings (Key Impairments) ICF Body Functions codes : b7150.3 MILD impairments of stability of a single joint
As above with the following differences:
- Resisted tests are now strong and painful only with repeated shoulder flexion and abduction
- Pain with repetitive activities of the shoulder especially at end range
- Pain with sustained end ranges stresses to the A/C, such as with prone-on-elbows positions
- Re-injury Prevention Instruction Progress activities to tolerance
Intervention for High Performance / High Demand Functioning in Workers and Athletes
Goal: Return to desired occupational or sport activities
- Therapeutic Exercises Progress exercises focusing on job/sport specific training program based on individual needs of patient.
