1
Q

Type of Orthotic: Advantages

  • Lightweight
  • Easy to don/doff
  • Cosmetic
  • Able to wear in any shoe (in theory)
A

MAFO

2
Q

Type of Orthotic: Disadvantages

  • Only a little knee stability
  • Concern about plastic if swelling, sensory loss
A

MAFO

3
Q

Type of Orthotic: Comments

  • Most common choice
  • Narrow / wide trim lines to adjust ankle flexibility / stability
  • Options: Post leaf spring, articulating ankle
  • Initiate gradual wearing schedule and monitor skin
A

MAFO

4
Q

Type of Orthotic: Advantages

  • More knee stability
  • More options with ankle joint (assist / stop / etc)
  • Easiest to don / doff
A

AFO

5
Q

Type of Orthotic: Disadvantages

  • Heavier
  • Uglier
  • Can only wear with 1 shoe
A

AFO

6
Q

Type of Orthotic: Comments

  • Choice if can’t use MAFO because of fluctuating edema OR if knee very unstable (buckling or hyperextend)
  • If unilateral weakness, this should be enough for knee control
A

AFO

7
Q

Type of Orthotic: Advantages

  • Most knee stability, some hip stability
A

KAFO

8
Q

Type of Orthotic: Disadvantages

  • TOO HEAVY
  • Very difficult to don / doff
A

KAFO

9
Q

Type of Orthotic: Comments

  • Only use as last resort if nothing else works OR if significant bilateral weakness
A

KAFO

10
Q

Describe the effect of the weight of an orthotic on gait

A

The orthotic provides stability in stance but can hender swing due to the increased weight of the orthotic

11
Q

Describe the decision algorithm for determining the correct orthotic (3)

A
  • Brace vs. no brace
  • AFO vs. MAFO
  • Ankle set up (PF vs. DF)
12
Q

Describe the purpose of a swedish knee cage

A

It sets the knee in ~ 5 degrees of knee flexion and prevention extension in attempt to prevent knee hyperextenstion during stance

13
Q

Type of Orthotic: temporary, for evaluation and early mobilization

A

Pre-Fabricated AFO

14
Q

Type of Orthotic: weakness expected for > 6 mo; improve balance/stability/WB

A

Custom MAFO or AFO

15
Q

Describe Medicare’s Guidelines for AFO modification/replacement

A

If the orthotic is lost, damage, or there is a change in the pt.’s condition

NO time frame restrictions

16
Q

Term: Use of estim for orthotic substitution and ehance function

A

FES

17
Q

List the uses for FES (5)

A
  • Reduce shld subluxation
  • Ankle DF during gait
  • LE cycle ergometry
  • Full gait cycle
  • Reaching activities
18
Q

Describe the effect of FES on shoulder subluxation

A

Tx to supraspinatus and posterior deltoid mm is beneficial for reducing hemiplegic shoulder pain. This low risk tx can be used any time after stroke

19
Q

List the indications for use of FES foot drop stimulation

A

Use foot drop following an upper motor neuron injury or disease: Stroke, TBI, SCI, MS

20
Q

List when FES stimulation for foot drop is turned on and off turning gait?

A

Heel off: stimulation on

Heel strike: stimulation off

21
Q

Describe the possible operating modes for FES for foot drop (3)

A

Gait mode: ultilized for walking

Training mode: utilized for therapeutic mm training

Clinician’s mode: utilized to enhance clinical training

22
Q

List the electrode placement for FES for foot drop (2)

A

1: over common peroneal nerve; posterior and distal to fibular head
2: over tibialis anterior mm
