Q

What is the knee doing during heel strike (initial contact) to foot flat (loading response)? What muscle activation would allow for the control of this?

A

Moving from full Extension to 15-20 degrees flexion as the limb accepts the weight of the body (loading response)
- eccentric quads to control the amount of knee flexion during loading

24
Q

During heel strike (initial contact) the knee is in

A

Full extension 0 degrees

25
Q

During foot flat (loading response), the knee is at

A

15- 20 degrees of knee flexion

26
Q

What is the knee doing during foot flat (loading response) to Midstance? What muscle activation would allow this?

A

Extending back to neutral
- concentric quads until neutral knee extension (then activity in the knee musculature is minimal during midstance)

27
Q

What is the knee doing during midstance to heel off (terminal swing) and toe off (preswing)?

A

Knee muscle activity remains limited in late stance until the hamstrings begin to produce knee flexion at toe off (preswing) in preparation for the swing phase (momentum of body, also aids in this motion)

28
Q

What is the knee doing during Acceleration (initial swing) to Midswing? What muscle activation would allow this to shorten the swing leg?

A

Moving into about 60 degrees of knee flexion.
- concentric hamstrings to bend the knee for foot clearance in early swing

29
Q

What is the knee doing during midswing to deceleration (terminal swing)? what muscle activation would control this?

A

Momentum of swing is moving the knee back into full extension
- eccentric hamstrings to slow the rate of knee extension during terminal swing

30
Q

If the quadriceps are weak, what is the common gait deviation seen during stance phase?

A

Anterior trunk lean in early stance
- compensates for quadriceps weakness by moving the ground reaction force anterior to the knee to “lock” the knee in extension

31
Q

If the hamstrings are weak, what are the common gait deviation in swing phase?

A

Poor deceleration in terminal swing
- hamstrings eccentrically slow hip flexion and knee extension (deceleration) during terminal swing (before heel strike)
- hamstrings mainly function during stance phase as a stabilizer for the knee (quadriceps more active in stance phase and hamstrings more active in swing)

32
Q

What is the hip doing during heel strike (initial contact) to foot flat (loading response)? What muscle activation would allow for this?

A

Hip is in about 30 degrees flexion and stabilizing (in preparation more movement into extension)
- Isometric hip extensors (gluteus Maximus) and hip abductors (gluteus medius and minimus)

33
Q

What is the hip doing during foot flat (loading response) to midstance? What muscle activation would allow this?

A

Moving from 30 degrees flexion into extension (neutral)
- concentric hip extensors (gluteus Maximus) to become more erect with hip abductors still stabilizing hip and pelvis.

34
Q

What is the hip doing during midstance to Heel off (terminal stance) and toe off (preswing)? What muscle activation would allow this?

A

Moving from a neutral hip to 10 degrees extension (beyond neutral)
- Eccentric hip flexors (iliopsoas) to control or slow the rate of hip extension

35
Q

What is the hip doing during acceleration (initial swing) to midswing? What muscle activation would allow this?

A

Moving from extension into 20-30 degrees of flexion
- concentric hip flexors (iliopsoas) to advance the swing limb forward.

36
Q

what is the hip doing from midswing to deceleration (terminal swing)? What muscle activation would allow this?

A

Moving (deceleration) into 30 degrees of flexion
- eccentric hips extensors to slow the rate of hip flexion and prepare the limb for heel strike (initial contact)

37
Q

If the gluteus Maximus is weak, what is the common gait deviation in stance phase?

A

Posterior trunk lean
- during early stance compensated for hip extensor weakness by moving the line of gravity of the trunk behind the hip joint to “lock” the hip in extension

38
Q

If the gluteus medius is weak, what is the common gait deviation seen in stance phase?

A

Lateral Trunk Lean
- lean toward the stance leg of the weak hip abductors to prevent contralateral drop of the pelvis on the side of the swing leg

39
Q

Hip Abductors are not active during the

A

Swing phase in normal gait

40
Q

Trendelenburg Sign

A

Contralateral (opposite side) pelvic drop

41
Q

Trendelenburg gait

A

The lateral trunk lean toward weak stance limb

42
Q

If the hip flexors are weak, what is the common gait deviation in swing phase?

A

Posterior trunk lean
- during early swing phase helps pull the femur forward (anteriorly) to advance the swing limb as a compensation for hip flexor weakness

Other:
- hip circumduction
- insufficient hip flexion at terming swing= shorter step length

43
