Gait Deviations

Question 1

Lateral Trunk Bending–Prosthetic Causes

Answer 1

• -short prosthesis
• -inadequate lateral wall adduction
• -high or sharp medial wall
• -prosthesis aligned in abduction

Question 2

Lateral Trunk Bending—Anatomical Causes

Answer 2

• -Poor balance/instability
• -abduction contracture
• -poor gait training
• -short residual limb
• -weak hip abductors on prosthetic side
• -hypersensitive and/or painful residual limb

Question 3

Abducted gait–Prosthetic Causes

Answer 3

• -prosthesis too long
• -high medial wall
• -poorly shaped lateral wall (not enough adduction)
• -prosthesis positioned in abduction
• inadequate suspension
• -excessive knee friction

Question 4

Abducted Gait–Anatomical Causes

Answer 4

• -abduction contracture
• -weak hip flexors and adductors
• -pain over lateral residual limb
• -adductor roll/adductor redundancy instability

Question 5

Circumducted Gait–Prosthetic causes

Answer 5

• -Prosthesis too long
• -socket too small
• -loose socket
• -loose friction vs too much friction
• -excessive plantar flexion of prosthetic foot
• -inadequate suspension
• -locked knee

Question 6

Cirucumducted Gait–Anatomical Causes

Answer 6

• -abduction contracture
• -improper training
• -weak hip flexors
• -poor knee control/lack of confidence to flex the knee/inability to initiate knee flexion
• -painful anterior distal residual limb

Question 7

Excessive knee flexion during stance–prosthetic causes

Answer 7

• -high shoe heel
• -insufficient plantarflexion
• -stiff heel cushion
• -socket too far anterior
• -socket excessively flexed
• -cuff tabs too posterior

Question 8

excessive knee flexion during stance–anatomical causes

Answer 8

• -knee flexion contracture
• -weak quadriceps
• -hip flexion contracture
• -pain anteriorly in residual limb
• -poor balance

Question 9

Vaulting–prosthetic causes

Answer 9

• -prosthesis too long
• -inadequate socket suspension
• -excessive alignment stability
• -foot in excessive plantarflexion

Question 10

Vaulting–anatomical causes

Answer 10

• -residual limb discomfort
• -improper training
• -fear of stubbing toe
• -short residual limb
• -painful hip on residual limb side

Question 11

Rotation of forefoot at heel strike–prosthetic causes

Answer 11

• -steel heel cushion/rigid SACH heel cushion
• -excessive toe-out built in/malrotated foot
• -loose fitting socket
• -inadequate suspension

Question 12

Rotation of forefoot at heel strike–anatomical causes

Answer 12

• -poor muscle control
• -improper training
• -weak medial rotators
• -short residual limb

Question 13

Forward trunk flexion–prosthetic causes

Answer 13

• -socket too big
• -poor suspension
• -knee instability
• -short walker or crutches

Question 14

Forward Trunk flexion–anatomical causes

Answer 14

• -hip flexion contracture
• -weak hip extensors
• -pain with ischial weight bearing
• -inability to initiate prosthetic knee flexion

Question 15

Medial or lateral whip–prosthetic causes

Answer 15

• -excessive rotation of the knee
• -tight socket fit
• -valgus in the prosthetic knee
• -improper alignment
• -faulty socket contour

Question 16

Medial or lateral whip–anatomical causes

Answer 16

• -improper training
• -weak hip rotators
• -knee irritablity
