Transtib Gait Deviations

Drop-Off Prosthetic Causes

Toe lever too short, foot too dorsiflexed, too much socket flexion

Drop-Off Patient Causes

Gait habit, internal hip rotation at toe-off

Drop-Off Prosthetic Causes

Toe lever too short, foot too dorsiflexed, too much socket flexion

Drop-Off Patient Causes

Gait habit, internal hip rotation at toe-off

Delayed Heel-Off Prosthetic Causes

Toe lever too long, foot too plantarflexed, insufficient socket flexion

Delayed Heel-Off Patient Causes

Gait habit, new shoes since measurement with lower heel height

Vaulting Prosthetic Causes

Long prosthesis, poor suspension, foot too plantarflexed

Vaulting Patient Causes

Gait habit (fear of catching toe), weak hip flexors on prosthetic side

Circumduction Prosthetic Causes

Long prosthesis, too much plantar flexion, ineffective suspension

Circumduction Patient Causes

Lack of confidence flexing knee, abduction contracture, weak hip flexors, habit

Trendelenburg Prosthetic Causes

Prosthesis too short, foot too outset, socket fit issues

Trendelenburg Patient Causes

Weak hip musculature, poor gait habit

Uneven Step Length Prosthetic Causes

Pain in socket, excessive plantarflexion, insufficient socket flexion, toe lever too long

Uneven Step Length Patient Causes

Patient lacks confidence, hip contractures

Varus Moment Prosthetic Causes

Foot too inset, insufficient socket adduction, short prosthesis

Varus Moment Patient Causes

Inadequate balance, weak knee, narrow gait base

Valgus Moment Prosthetic Causes

Foot too outset, excessive socket adduction

Valgus Moment Patient Causes

Insecurity (widens base for stability), weak ML knee control

Toe Drag Prosthetic Causes

Long prosthesis, inadequate suspension, excessive plantarflexion, insufficient socket flexion

Toe Drag Patient Causes

Weak hip extensors and abductors on sound side, poor posture, gait habit

Wide Base of Support Prosthetic Causes

Foot too outset, excessive adduction

Wide Base of Support Patient Causes

Insecurity (widens base for stability), weak ML knee control, hip abductor contracture

Narrow Base of Support Prosthetic Causes

Foot too inset, excessive socket abduction

Narrow Base of Support Patient Causes

Gait habit, Hip adductor contracture

Knee Instability (Excessive Knee Flexion) Prosthetic Causes

Foot too dorsiflexed, heel bumper too stiff, heel lever too long

Knee Instability (Excessive Knee Flexion) Patient Causes

Knee flexion contracture, weak quads

Medial Whip Prosthetic Cause

Foot too ext. rotated

Medial Whip Patient Causes

Improper donning, external rotation of knee at toe-off

Lateral Whip Prosthetic Cause

Foot too int. rotated

Lateral Whip Patient Causes

Improper donning, internal rotation of knee at toe-off
