Q

solid ankle channels

A

DF and PF stop
both channels - ball, pin, screw, screw all the way down

23
Q

limited motion channels

A

both channels - ball, pin, screw
length of pin or how far screw is tightened is dependent on wanted range

24
Q

ex: patient needs 10 deg DF so which channel would you loosen

25
Q

PF stop channels

A
  • anterior channel: open
  • posterior channel: ball, pin, screw, screw all the way down
26
Q

DF stop channel

A
  • anterior channel: ball, pin, screw, screw all the way down
  • posterior channel: open
27
Q

DF assist channels

A
  • anterior channel: open
  • posterior channel: ball, spring, screw, screw all the way down
28
Q

PF assist channels

A
  • anterior channel: ball, spring, screw, screw all the way down
  • posterior channel: open
29
Q

free motion channels

30
Q

DF stop, PF stop, DF assist channels

A
  • anterior channel: ball, pin, screw (length of pin or how far screw is tightened is dependent on wanted range
  • posterior channel: ball, narrow pin, spring, screw, screw all the way down
31
Q

KAFO solid ankle channels

A

both channels ball, pin, screw
screw all the way down

32
Q

plastic solid trimlines

A

anterior to malleoli

33
Q

plastic rigid trimlines

A

bisect malleoli

34
Q

plastic semi-rigid trimlines

A

behind malleoli

35
Q

flexible/posterior leaf spring trimlines

A

very posterior to malleoli

36
Q

articulating components

A

free DF, PF stop, DF assist possible

37
Q

solid ankle direct effects on gait

A

foot clearance and protect calf musculature from sudden stretch

38
Q

limited motion direct effects on gait

A

foot clearance and protect calf musculature from sudden stretch

39
Q

PF stop direct effects on gait

A

foot clearance

40
Q

DF stop direct effects on gait

A

prevents rapid tibial progression as transition from heel strike to midstance therefore prevents overstretching of calf musculature

41
Q

DF assist direct effects on gait

A

improved foot clearance and eliminates foot slap at heel strike

42
Q

PF assist direct effects on gait

A

possible assistance for standing balance; possible assistance for foot control for push off

43
Q

free motion direct effects on gait

A

inversion/eversion control

44
Q

DF stop, PF stop, DF assist direct effects on gait

A

foot clearance and protect calf musculature from sudden stretch

45
Q

KAFO with solid ankle direct effects on gait

A

foot clearance and protect calf musculature from sudden stretch

46
Q

solid ankle indirect effects on gait

A
  • prevent knee buckling and hyperextension
  • decreased compensations at hip by creating better foot clearance
47
Q

limited motion indirect effects on gait

A

provide knee stability and decreased compensations at hip by creating better foot clearance

48
Q

PF stop indirect effects on gait

A
  • control for knee hyperextension
  • decreased compensations at hip by creating better foot clearance
49
Q

DF stop indirect effects on gait

A

control rapid knee flexion after heel strike moving to midstance

50
Q

DF assist indirect effects on gait

A

decreases compensations at hip by creating better foot clearance

51
Q

PF assist indirect effects on gait

52
Q

free motion indirect effects on gait

53
Q

DF stop, PF stop, DF assist indirect effects on gait

A

knee stability and decreased compensations at hip by creating better foot clearance
