1

a static or dynamic externally applied device use to improve function.

Orthosis

2

What are outcomes of orthotics?

Prevent deformity
Correct deformity
WB support
Assist or limit mvmt.
Decrease pain
Improve posture
Immobilize
Provide feedback
Improve cosmoses

3

Indications for orthotics

impaired:
posture
muscle performance
Jt mobility
motor fx
sensory integrity
prophylactic

4

resists or directs force

brace

5

maintains or attains a position

splint

6

Know nomenclature:
FO/AO/KO/HPO/AFO/KAFO

..

7

UE nomenclature:
HO/EO/SO/WHO/SEWHO

..

8

different materials that orthotics come in

thermoplastic
metal
carbo fiber

9

Principles of design include

Pressure distribution (f/a)
Length of force arm
Ground reaction force
control degrees of freedom

10

3 pt. pressure system shows

2 supports on one side,
one on the other

11

how would you set up wc with 3 point pressure system to reverse decorticate posturing?

tilt the wheelchair.

12

corrects limb length discrepancies

foot lift

13

reduce achilles tendon stress

Heel lift

14

redistribute fat pad to improve shock absorbtion (plantar fasciitis)

heel cup

15

Reduces WB through metatarsals, Talocrural, and subtler joints

AFO patellar tendon WB

16

immobilize ankle jt, rocker bottom, able to adjust, doesn't unload distal structures

Cam walker

17

Greater trim lines in Orthoses used to control

more tone

18

a long foot plate resists pf __ than a short one

more

19

PLS AFO

posterior leaf spring afo

20

normalized gait to decrease energy expedenture

articulated afo

21

what do the stops in the articulated afo help control

amt of mvmt in DF or PF

22

controls tibial advancement and helps maintain knee ext during mid stance.

ground reaction afo

23

ground reaction afo compensate for

weak pf

24

KO designed to_____ but really it just ____

prevent re-injury

reduces chances. it's not as protective as the normal knee. sigh.

25

for these conditions what does the brace do:
Genu valgum
gene vacuum
unloader braces

-unload WB on lateral compartment

-unload WB on medial compartment

- use 3pt pressure system to redistribute WB

26

T-strap orthosis alters

patellar tracking

27

how does patellar strap work?

decreases strain on patella by decreasing tendon angle

28

KAFO with WB through ischium does what

unloads proximal tibia and femoral condyles

29

PF __ extension force at knee

produces

30

DF __ extension at knee

releases
