TF Gait

Question 1

Softer heel

Answer 1

Increase knee stability throws reaction line anterior

Question 2

Too stiff heel

Answer 2

Decrease knee stability- external rotation foot

Question 3

Loss of hip extensor power

Answer 3

More proximal amputation

Question 4

Transfemorals requires greater cushioning

Answer 4

No shock attenuation from knee

Question 5

Need anterior support in foot

Answer 5

Drop off is loss of support

• dangerous
• knee center move anterior
• knee buckles

Question 6

Keels too stiff for AK

Answer 6

Difficult to toe-off

Question 7

TF foot selection plantarflexing foot

Answer 7

Create knee extension sooner- foot flat faster

Question 8

Voluntary alignment

Answer 8

Knee axis is anterior to TA line
Easy to flex knee at PSw 
More normal gait pattern
No mechanical stability at IC
Indicated for patient with + hip extensor power

Question 9

Involuntary alignment

Answer 9

Knee axis is posterior to TA line
More difficult to flex knee at PSw
Adverse effect to normal gait pattern
Mechanical stability at IC
Indicated for patient with limited hip extensor power
Contra indicated for mechanical locking knee components

Question 10

Shorter limb length increases load

Answer 10

Increases load
Changes alignmnet
Outset foot to decrease

Question 11

Lateral trunk bending

Answer 11

Brings CG closer
Lateral distal pain- short limb length
Alignment too inset
Proximal pain

Question 12

Abducted gait

Answer 12

Brings fulcrum closer
- Ramal discomfort
- leg too long
No femoral support
