16
Q

What are common problems in swing after stroke??

A

Decreased propulsion prior to swing phase
Decreased knee flexion and ankle DF in swing
Compensatory circumduction or elevation of pelvis

17
Q

What problem at the hip can cause decreased hip extension in stance

A

Flexor contracture
Weak concentric hip extension
Decreased eccentric hip abd

? Eccentric hip flexor

18
Q

What problem at the knee can cause decreased hip extension in stance

A

Quad weakness

19
Q

What problem at the ankle can cause decreased hip extension in stance

A

decreased DF

decreased eccentric PF

20
Q

Correct way of wording treatment goal for somebody who needs to improve DF

A

need to increase range, strength and speed of concentric dorsiflexion

21
Q

What problem at the hip can cause knee hyperxtension in stance

A

decreased hip extension

22
Q

What problem at the knee can cause knee hyperxtension in stance

A

decreased eccentric hamstrings

Lack of control in inner range

23
Q

What problem at the ankle can cause knee hyperxtension in stance

A

Any cause of decreased DF

24
Q

What problem at the hip can cause increased knee flexion in stance

A

Decreased ext

25
Q

What problem at the knee can cause increased knee flexion in stance

A

Contracture of knee flexors

Decreased concentric quads inner range

26
Q

What problem at the ankle can cause increased knee flexion in stance

A

decreased eccentric PF

27
Q

Reasons for increased lateral pelvic shift

A

Cannot control the shift and go too far (lack eccentric hip Abd.)

28
Q

Reasons for decreased lateral pelvic shift

A

Don’t shift weight enough. - concentric hip Abd

29
Q

Reasons for decreased ankle PF at end of stance (hip)

A

Any cause of not staying on the leg long enough. - Decreased Hip extension, decreased control Hip Abd (don’t want to stay on one leg)

30
Q

Reasons for decreased ankle PF at end of stance (Knee)

A

Any cause not wanting to stay on leg long enough. decreased knee extension

31
Q

Reasons for decreased ankle PF at end of stance (ankle)

A

Loss of dexterity required to switch from eccentric PF to concenctric PF rapidly with large force

32
Q

Reasons for decreased hip flexion in swing

A

Not in the right position for the start of swing.

  • any cause of lack of hip extension.
  • decreased concentric hip flexion
33
Q

Causes decreased knee flexion in swing

A

Knee flexion normally happens after a burst of PF and Hip Ext and is a pendular movement. Address these other joints as causes instead of just giving exercises for hamstrings.

34
Q

Reasons for decreased ankle dorsiflexion in swing

A
Decreased concentric DF strength
Joint
Spasticity
Muscle length
Lack of dexterity in switch between DF and PF
