Q

What is double support, when does it occur, and for how much of the gait cycle does it occur?

A
  • Double support is when two feet are in contact with the floor at the same time
  • It happens at (R) heel off/(L) heel strike and (R) toe off/(L) foot flat
  • 10% of the gait cycle

  • Parkinsonian
  • Scissor
  • Crouch
22
Q

Which type of abnormal gait is characterized by the person shifting their body to the uninvolved side, circumducting the affected limb during swing phase, landing flat-footed, lacking reciprocal arm swing, and a step length that is longer on the affected side?

A

Hemiplegic Gait

23
Q

Which type of abnormal gait is characterized by trouble with balance, wide base of support, jerky movements, difficulty walking in a straight line, and jerky arm motion?

A

Ataxic Gait

24
Q

Which type of abnormal gait is characterized by flexion of the LE and trunk, deminished arm swing, shuffling gait, difficulty initiating movements, and “Festinating Gait”?

A

Parkinsonian Gait

25
Q

Which type of abnormal gait is characterized by excessive lumbar lordosis, anterior pelvic tilt, hip and knee flexion, ankle plantar flexion, and exaggerated arm swing?

A

Crouch Gait

26

30
Q

What are the attachment points for the rotator cuff muscles?

A

The greater and lesser tubercles of the humerus

31
Q

Which muscles attach to the greater tubercle of the humerus?

A

The Supraspinatus, Infraspinatus, and Teres Minor

32
Q

Which muscles attach to the lesser tubercle of the humerus?

A

The Subscapularis

33
Q

Where is the Coracohumeral Ligament located, what does it attach to, and what does it do?

A
  • The superior aspect of the shoulder
  • Attaches from the lateral side of the coracoid process to the medial side of the greater tubercle
  • It strengthens the upper part of the joint capsule
34
Q

Where is the Glenohumeral Ligament located and what does it do?

A
  • The anterior aspect of the shoulder

- Reinforces the anterior portion of the capsule

35
Q

What is the Glenoid Labrum and what does it do?

A
  • It is fibrous tissue surrounding the glenoid fossa

- It deepens the articular cavity

36
Q

What is another name for the Thoracolumbar Fascia, what is it, what does it attach to, and what does it do?

A
  • AKA Lumbar Aponeurosis
  • It is a superficial fibrous sheet
  • It attaches to the spinous processes of the lower thoracic and lumbar vertebra, supraspinal ligament, and the posterior part of the iliac crest
  • It provides a broad attachment for the latissimus dorsi
37
Q

What is the Rotator Cuff and what does it do?

A
  • It is a tendinous band formed by the insertions of the Supraspinatus, Infraspinatus, Teres Minor, and Subscapularis
  • These muscles help keep the head of the humerus “rotating” against the glenoid fossa by stabilizing/depressing the humerus in the glenoid
38
Q

How far can the Glenohumeral Joint flex before the scapula starts to move with it?

A

120 Degrees

39
Q

How far can the Glenohumeral Joint abduct before the scapula starts to move with it?

A

120 Degrees
