1

What is Lateral Bending of the Trunk?

Excessive bending laterally from the midline, generally to the prosthetic side.

2

What are the prosthetic causes of Lateral trunk bending?

Prosthesis too short or long
Improperly shaped Lateral wall
High Medial wall
Prosthesis aligned in abduction
Excessive foot outset
Pain at distal lateral femur

3

Why does a improperly shaped lateral wall produce the lateral bend deviation?

Fails to support the femur

4

Why does a high medial wall cause the lateral bend deviation?

May cause pain and the patient to lean away from the discomfort

5

Why does an abducted socket produce lateral bend deviation?

Causes wide-based gait

6

What are amputee causes of lateral trunk bend?

Inadequate balance
Abduction contracture
Over-sensitive residual limb to pain
Very Short limb-no lever arm
Habit

7

What is abducted gait?

A very wide base with the prosthesis held away from the midline at all times

8

what are prosthetic causes of abducted gait?

Prosthesis too long
Prosthesis to abducted
High medial wall
Improper lateral wall shape
Pelvic band positioned far away from the patient's body
Pain at distal lateral femur

9

What are amputee causes of abducted gait?

Abduction contracture
Habit
Anterior pelvic tilt

10

What is circumducted gait?

Swinging the prosthesis laterally in a wide arc during swing phase.

11

What are the prosthetic causes of a circumducted gait?

Prosthesis too long
Knee too stable
Excessive resistance to knee flexion
Extension bias too strong
Medial brim pressure
inadequate suspension

12

What are amputee causes of circumducted gait?

Abducted contracture
Lacks confidence in leg
Habit

13

What is Vaulting?

A rising on the toe of the normal foot permitting the amputee to swing the prosthesis through with little knee flexion

14

What are the prosthetic causes of vaulting?

Prosthesis too long
Inadequate socket suspension
Limb discomfort
Excessive resistance to knee flexion
Too much stability
Extension bias too strong

15

What is the amputee cause of vaulting?

Habit
Fear of stubbing toe
Limb discomfort

16

What are the prosthetic causes of Rotation of the prosthetic foot on heel strike?

Too much resistance to plantarflexion by the bumper or heel wedge
Too much toe out
Socket too loose
Tight medial/posterior wall angle
Foot inset too far

17

What are the amputee causes of rotation of the prosthetic foot on the heel strike?

Extends the residual limb to vigorously at heel strike
Poor muscle control

18

What is uneven arm swing?

The arm on the prosthetic side held close to the body during locomotion

19

What are the prosthetic causes of uneven arm swing?

Improperly fitting socket-can cause discomfort

20

What are the amputee causes of uneven arm swing?

Bad balance
Fear and insecurity
Habit

21

What is uneven timing?

Steps of unequal duration, usually a very short stance phase on prosthetic side.

22

What are the prosthetic causes of uneven timing?

Improperly fitting socket
Weak extension aid or friction in knee
Alignment instability of knee
Insufficient initial socket flexion-for hip flexion contracture

23

Why would a weak extension aid or friction in knee cause uneven timing?

Excessive heel rise resulting in a prolonged swing-through.

24

What are the amputee causes of uneven timing?

Muscle weakness
Bad balance
Fear and insecurity

25

What is uneven heel rise?

The prosthetic heel rising quite markedly and rapidly when the knee is flexed at beginning of swing phase.

26

What are the prosthetic causes of uneven heel rise?

Knee joint has insufficient friction
Inadequate extension aid

27

What are the amputee causes of uneven heel rise?

Using more power than neccessary to force the knee into flexion

28

What is terminal swing impact?

Rapid forward movement of the shank allowing the knee to reach maximum extension with too much force before heel strike

29

What are the prosthetic causes of terminal impact?

Insufficient knee friction
Knee extension aid too strong
Used or absent extension bumper

30

What are the amputee causes of terminal impact?

Amputee reassure himself that the knee is extended
