Mobility is dependent on? |
ROM, Flexibility |
|
What limits ROM in leg "ball and socket" joint as opposed to shoulder? |
Attachment to the sacrum |
|
What 4 things affect ROM? |
1. FLEXIBILITY 2. Muscles surrounding 3. Ligaments (bone to bone) 4. Tendon (muscle to bone) |
|
Definition of Flexibility |
Absolute range of motion |
|
Gold Standard test for ROM? (Problems) |
Sit and Reach test Harder for people with long legs |
|
Can loss of ROM be permanent? |
YES |
|
Define Wolff's Law (examples) |
Bone/tissue adapts under load which it is placed (bow-legged from heavy diapers as child, chronically assumed posture) |
|
Closing of _________ indicates stop of boney growth |
Sutures |
|
Stretch _______ muscles and strengthen _________ muscles |
Tight/overused Weak/underused |
|
Explain "Head over Pelvis", examples |
Concept that body will naturally return head to position over pelvis Ex. 1 "C" shaped spine warps into "S" shape to return head over pelvis Ex. 2 Unilateral contracture of sternocleidomastoid |
|
Importance of Coracoacromial ligamnet |
Forms roof over head of humerus while throwing (Coracoid Process to Acromion) |
|
Importance of coracoid process |
Impact stabilizer for falling on outstretched hands TRANSFERS FORCE TO CLAVICLE |
|
Function of Bursae |
Sacs filled with Synovial fluid that prevent friction |
|
Function of Capsular Ligament |
Holds humeral head in glenoid fossa |
|
Ligaments of the Sternoclavicular Joint |
1. Sternoclavicular 2. Interclavicular 3. Costoclavicular |
|
Ligaments of Acromioclavicular Joint |
1. Acromioclavicular 2. Coracoclavicular 3. Coracoacromial |
|
Ligaments Glenohumeral Joint |
1. Coracohumeral 2. Transverse Humeral Bursae |
|
Movements of Shoulder Girdle |
Adduction (Scapula towards spine), Abduction (Scapula away from Spine), Elevation, Depression, Upward Rotation, Downward Rotation |
|
Trapezius (Upper Fibers) |
O: External Occipital Protuberance, Ligament of Nuccae I: Posterior Clavicle A: Elevation of Scapula, Upward Rotation, Extension/Rotation of Head |
|
Trapezius (Middle Fibers) |
O: C7-T3 Spinous Process I: Medial Border of Acromion process, Upper border of Scapular spine A: Elevation, Upward Rotation, Adduction of Scapula |
|
Trapezius (Lower Fibers) |
O: T4-T12 Spinous Process I: Base of Scapular Spine A: Depression, Adduction, Upward Rotation of Scapula |
|
Why is Shoulder Joint Flexion and Abduction difficult with a weak Trapezius? |
Trapezius contracts scapula in upward rotation which aids in shoulder joint flexion |
|
Levator Scapula |
O: C1-C4 Transverse Process I: Medial Border of scapula from superior angle to Spine A: Elevation, Adduction, downward rotation, Cervical Extension, Lateral flexion of one side of head |
|
Rhomboid Major and Minor |
O: Spinous Process of C7-T5 I: Medial Border of Scapula, Inferior border of Scapular Spine A: Adduction, Downward Rotation, Elevation |
|
Subclavius |
O: 1st Rib I: Inferior Groove of Clavicle A: Depression, Abduction Primary Function: Secures shoulder joint ***Holds clavicle to Sternum |
|
Pectoralis Minor |
O: Anterior Surface of Ribs 3-5 I: Coracoid Process of Scapula A: Abduction, Downward Rotation, Depression ***Aids on inhalation |
|
Serratus Anterior |
O: Upper nine ribs on lateral sides of chest I: Anterior, medial border of Scapula A: Abduction, Upward Rotation Special Nickname: Boxer's Muscle |
|
Sternocleidomastoid |
O: Manubrium of Sternum, Medial Portion of Clavicle I: Mastoid Process of Clavicle A: Rotation to opposite side, lateral flexion to same side, Cervical spine flexion, ***Assists in forced exhalation |
|
Levator Scapulae PD Example |
Holding Backpack on one side |
|
Rhomboids PD Example |
Inferior Angle of Scapula will pop up in muscle weakness (Forward Tilt) |
|
Serratus Anterior PD Example: WINGED SCAPULA |
Flaring of Medial Border of Scapula |
|
Sternocleidomastoid PD: WRYNECK |
Unilateral Contracture of Sternocleidomastoid |
|
Sprengel's Deformity |
Unilateral elevation of Scapula Etiology: Failure of Scapula to descend during embryological development |
