Gait Deviations Prosthesis

Question 1

Lateral Bending

Answer 1

• Prosthesis may be too short
• Prosthesis aligned in abduction
• Short residual limb
• Weak hip abductors on prosthetic side

Question 2

Abducted Gait

Answer 2

• Prosthesis may be too long
• Prosthesis positioned in abduction
• Inadequate suspension
• Excessive knee friction
• Adductor roll
• Weak hip flexors and adductors

Question 3

Circumducted Gait

Answer 3

• Prosthesis may be too long
• Socket is too small
• Excessive plantar flexion of prosthetic foot
• Weak hip flexors
• Lacks confidence to flex the knee
• Painful anterior distal residual limb

Question 4

Excessive Knee Flexion During Stance

Answer 4

• Socket set forward in relation to foot
• Foot set in excessive dorsiflexion
• Prosthesis too long
• Knee and/or hip flexion contracture
• Decrease in quadriceps strength

Question 5

Forward Trunk Flexion

Answer 5

• Socket too big
• Poor suspension
• Knee instability
• Weak hip extensors
• Inability to initiate prosthetic knee flexion

Question 6

Vaulting

Answer 6

• Prosthesis may be too long
• Inadequate socket suspension
• Excessive alignment stability
• Foot in excessive plantar flexion
• Short residual limb

Question 7

Rotation of Forefoot at Heel Strike

Answer 7

• Loose fitting socket
• Inadequate suspension
• Rigid SACH heel cushion
• Weak medial rotators
• Short residual limb

Question 8

Medial or Lateral Whip

Answer 8

• Excessive rotation of the knee
• Tight socket fit
• Valgus in the prosthetic knee
• Improper alignment of toe break
• Weak hip rotators
• Knee instability
