Q

Elements of Normal Gait

A

Proper Alignment: Head erect, Shoulders Level, Trunk Vertical
Reciprocal Arm Swing–arms travel same distance but alternate
Equal Stride Length
Synchronized timing
Body undergoes vertical oscillations that are definite and have even tempo
When one leg is forward, the opposite arm moves forward as well
Trunk and Upper extremity rotate in opposite directions
Stance should be longer than swing

Q

Stance Phase, name 5 descriptions:

A

Begins at Heel Strike
Leading leg prepares to receive the body weight transferred from the trailing leg
Hip and Knee extensors work to stabilize leg
Hip Abductors and Adductors stabilize the pelvis
Hip Extends until Heel Rises, then Hip and Knee Flex

Q

Swing Phase, describe 4 things during this phase:

A

After toe-off, trailing leg is lifted from the ground and starts to swing forward
Hip flexors start the swing
Leg swings like pendulum
Swinging leg carries pelvis forward on that side (so pelvis on that side is facing anteromedially). Femur must rotate laterally so toes will point ahead.

21
Q

What is the cause of Antalgic Gait?

A

Pain in a Weight-bearing Joint

22
Q

What are the clinical finding in an Antalgic Gait?

A

Decreased stance to reduce pain or keep off leg as much as possible

23
Q

What is the cause of Arthrogenic Gait?

A

Stiffness in joint

24
Q

What are the clinical findings in an Arthogenic Gait?

A

Lack of motion may be compensated by other joints
Hip hiking
Circumduction of Hip
Excessive Plantarflexion of ankle

25
Q

What is the cause of Trendelenburg Gait?

A

Weakness of Gluteus Medius or
Unstable Hip

26
Q

What are the clinical findings in the Trendelenburg Gait?

A

Weakness of Gluteus Medius causes dropping of pelvis on unsupported side so patient’s trunk sways over affected side
(If patient has weakness of Gluteus Medius on the right, when he stands on his right leg, the pelvis will drop on the left side and his trunk will sway over the right side.)

27
Q

What is the cause of Ataxic Gait?

A

Cerebellar Problem: Loss of balance and Coordination

28
Q

What is the cause of Slapping Gait/ Foot Drop Gait

A

Weakness of Tibialis Anterior

28
Q

What are the clinical findings in the Ataxic Gait?

A

Jerky Wide Base and Poor Balance

29
Q

What are the clinical findings in the Slapping Gait or Foot Drop Gait?

A

Knee is lifter higher than normal and foot slaps ground

30
Q

What is the cause of Parkinson Gait?

A

Parkinson’s Disease

31
Q

What are the clinical findings in the Parkinson Gait?

A

Shuffling Gait,
Difficulty starting and stopping,
Flexed Posture

32
Q

What are the clinical findings in the Spastic or Scissor Gait?

A

Knees rub and great effort is required to bring legs forward

33
Q

What is the cause of Spastic or Scissor Gait?

A

Overactivity of adductors,
extensors and
internal rotators of Hip

34
Q

What is the cause of Waddling Gait?

A

Guillain-Barre Syndrome

35
Q

What are the clinic findings in the of Waddling

A

General weakness of supporting muscles of pelvis–trunk thrown from side to side

36
Q

What are the clinical findings when a person has the Complete Vision Loss Gait?

A

Lean back until foot on ground before shifting weight forward

37
Q

What are the clinical findings when a person has an Artificial Limb?

A

Use hip to extend knee and lock it if above knee amp.

38
Q

Concerning the Trendelenburg Gait, and the right side is affected? When you stand on the _________ side, the ___________ side of the pelvis drops and the trunk sways over the ________ side.

A

Right
Left
Right

39
Q

Which muscles work most of the time throughout stance and swing to prevent slapping foot?

A

Dorsiflexors

40
Q

Which muscles work at ankle at push off to propel body forward?

A

Plantarflexors

41
Q

Which muscles prevent stiff knee contact at heel strike?

A

Hamstrings

42
Q

Which muscles work throughout much of swing phase to bring hip forward?

A

Hip Flexors

43
Q

Which muscles prevent knee from buckling during weightbearing?

A

Quadriceps

44
Q

Which muscles prevent pelvis from dropping on unsupported side during swing?

A

Hip Abductors

45
Q

Which muscles stabilize body on pelvis?

A

Hip Adductors

46
Q

Which muscles contract at heel strike to keep hip from collapsing?

A

Hip Extensors

47
Q

Which muscles stabilize vertebral column (balances trunk)?

A

Erector Spinae
