24
Q

Solid ankle AFO contraindications:

A 
LMN paralysis (flaccidity) or hypotonicity as primary problem
edema
25
Q

Tone inhibiting AFO actions:

A

Control ankle position throughout
Provide stance phase stability via ankle-knee coupling
Typically extended toeplate

26
Q

Tone inhibiting AFO indications:

A

Significant hypertonicity with seriously impaired motor control

27
Q

Tone inhibiting AFO contraindications:

A

LMN paralysis (flaccidity) or hypotonicity as primary problem

28
Q

Anterior floor reaction AFO actions:

A

Provide stability in stance via ankle-knee coupling

Control ankle position throughout stance

29
Q

Anterior floor reaction AFO indications:

A

Weakness or impaired motor control at knee and ankle

30
Q

Anterior floor reaction AFO contraindications:

A

Ligamentous insufficiency at the knee

Genu recurvatum

31
Q

Weight-relieving AFO action:

A

Protect lower leg and foot during stance by reducing weight bearing forces

32
Q

Weight relieving AFO indications:

A

Healing soft tissue, ligamentous, or bone injuries of the lower leg, ankle, or foot

33
Q

Weight relieving AFO contraindications:

A

Mechanical instability of the knee, or injury to proximal tibia
Pt intolerance of PTB WB forces (rare)

34
Q

Bilateral Metal upright (bars) AFO indications:

A 
Foot drop, post-polio, neuropathic feet
poor knee control in sagittal plane
ankle varus/valgus
foot drop with uncontrolled edema
poor skin below the knee
35
Q

Bilateral Metal upright (bars) AFO contraindications:

A

Pt’s concerns with bulk/weight

limits shoe wear

36
Q

Free motion/articulated/hinge AFO actions:

A

Allows sagittal plane motion
Free DF and PF
Limits coronal plane instabilities

37
Q

Free motion/articulated/hinge AFO indications:

A

Posterior tib tendon dysfunction

Subtalar or talar joint instabilities

38
Q

Free motion/articulated/hinge AFO contraindications:

A

Weak quads, sagittal plane ankle weakness

High impact sports

39
Q

DF Assist AFO actions:

A

Assist in clearance of toes while allowing for some PF
Variable DF assist
allows for controlled foot flat stance phase

40
Q

DF Assist AFO indications:

A

DF weakness

41
Q

DF Assist AFO contraindications:

A

Mod-severe tone levels in pts with altered knee control

42
Q

Posterior Stops in AFO action:

A

Immobilize ankle in swing and stance phase

If you only have a PF stop and DF is free, then it facilitates knee flexion in early stance

43
Q

Posterior Stops in AFO indications:

A

Structural collapse of the ankle foot, severe spasticity

44
Q

Posterior Stops in AFO contraindications:

A

Inadequate hip strength, absent quads, fluctuating edema, fixed/contracted spastic gastrocs

45
Q

DF stop/free plantar flexion action:

A

Facilitates knee extension and stiff ankle in late stance

46
Q

DF stop/free plantar flexion indications:

A

Weak PF and weak quads

47
Q

DF stop/free plantar flexion contraindications:

A

DF weakness

Knee hyperextension

48
Q

Solid Ankle foot orthosis (non articulated) indications:

A

Ankle instability/weakness in more than one plane
Equino varus
mod-severe pes plano valgus
mild-mod genu recurvatum

49
Q

Solid Ankle foot orthosis (non articulated) contraindications:

A

edema

50
Q

Spiral AFO actions:

A

Spiral has unwinding effect

51
Q

Spiral AFO indications:

A

Ankle DF weakness and/or PF ALONG with mild-mod ML instability

52
Q

Spiral AFO contraindications:

A

inadequate hip strength
mod-severe spasticity
severe ML ankle instability
fluctuating edema

53
Q

Ground/Floor Reaction AFO actions:

A

Provide ground forces to the knee which assist in stabilizing the knee during ambulation
For patients with weak quadriceps - it can achieve knee stability while maintaining efficiency by reducing weight and bulkiness

54
Q

Ground/Floor Reaction AFO indications:

A 
Crouched gait
Foot drop with knee instability
quadriceps weakness
MS
Spina bifida
55
Q

Ground/Floor Reaction AFO contraindications:

A

Genu recurvatum
ACL
Severely ER feet
Pts that do not have adequate trunk control or flaccid quad strength
