Aolani's case study

Movements that occur continuously throughout movement pattern + plane and axis:

• Finger flexion - Sagittal plane, frontal axis

• Thumb flexion - Frontal plane, sagittal axis

Movements occurring in phase 1 + plane and axis:

• Flexion at shoulder joint - Sagittal plane, frontal axis

• Abduction at shoulder joint - Frontal plane, sagittal axis

• Extension at elbow - Sagittal plane, frontal axis

Movements in phase 2 + plane and axis:

• Slight flexion at elbow - Sagittal plane, frontal axis

• Extension at shoulder joint - Sagittal plane, frontal axis

• Adduction at shoulder joint - Frontal plane, sagittal axis

Prime movers for finger flexion + location:

• Finger flexors - Anterior compartment of the forearm

Prime mover for thumb flexion + location:

• Flexor pollicis longus and flexor pollicis brevis - anterior compartment of the forearm and hand

Prime movers for elbow extension + origin and insertion:

Triceps brachii:

• Long head origin - Infraglenoid tubercle of the scapula

• Medial and lateral head origin - Posterior surface of the humerus

• Common insertion - Olecranon process of the ulna

Prime movers for shoulder flexion + origin and insertion:

Deltoid (anterior fibres):

• Origin of anterior fibres - Clavicle

• Insertion - Deltoid tuberosity of the humerus

Pectoralis major:

• Origins - Anterior surface of the clavicle, anterior surface of the sternum, anterior fibres of the external obliques

• Insertion: Bicipital grove of the humerus

Prime movers for shoulder abduction + origin and insertion:

Deltoid (middle fibres):

• Origin of middle fibres - Acromion process of the scapula

• Insertion - Deltoid tuberosity

Prime movers for elbow flexion + origin and insertion:

Biceps brachii:

• Long head origin - Supraglenoid tubercle of the scapula

• Short head origin - Coracoid process

• Common insertion: Radial tuberosity and deep faschia of forearm via the bicipital aponeurosis

Brachialis:

• Origin: Anterior aspect of the humerus

• Inserts: Tuberosity of the ulna

Brachioradialis:

• Origin: Lateral supracondylar ridge of the humerus

• Insertion: Lateral surface of the distal end of the radius

Prime movers for shoulder extension + origin and insertion:

Teres major:

• Origin - Posterior surface of the inferior angle of the scapula

• Insertion - Bicipital grove

Latissimus dorsi:

• Origin - Spinous process of the vertebra

• Insertion - Bicipital grove

Deltoid (posterior fibres):

• Origin - Spine of the scapula

• Insertion - Deltoid tuberosity

Prime movers for shoulder adduction + origin and insertion:

Pectoralis major:

• Origins - Anterior aspect of the clavicle, anterior surface of the sternum, and anterior fibres of the external oblique muscles

• Insertion- Bicipital grove

Lattissimus dorsi:

• Origin - Spinous process of the vertebra

• Insertion - Bicipital grove
