# Transtibial Prosthetic Gait Analysis ## Compensation/Deviation | Prosthetic Causes | Anatomical Causes **Early Stance** | | | | |---|---|---| | 1. Excessive knee flexion | Shoe heel too high Insufficient plantar flexion Heel cushion too stiff Socket too far anterior Socket excessively flexed. Cuff tabs too posterior | Flexion contracture Weak quadriceps | | 2. Insufficient knee flexion | Shoe heel too low Excessive plantar flexion Heel cushion too soft Socket too far posterior Socket insufficiently flexed | Extensor spasticity Weak quadriceps Anterior-distal pain Arthritis | **Midstance** | | | | |---|---|---| | 1. Lateral thrust | Excessive foot inset | | | 2. Medial thrust | Excessive foot outset | | **Late Stance** | | | | |---|---|---| | 1. Early knee flexion (also referred to as "drop off") | Shoe heel too high Insufficient plantar flexion Keel too short Dorsiflexion stop too soft Heel Socket too far anterior Socket excessively flexed | Flexion contracture | | 2. Delayed knee flexion: perception of walking | Shoe heel too low Excessive plantar flexion Keel too long Dorsiflexion stop too stiff Socket too far posterior Socket insufficiently flexed | Extensor spasticity | # Transfemoral Prosthetic Gait Analysis ## Compensation/Deviation | Prosthetic Causes | Anatomical Causes **Lateral Displacements** | | | | |---|---|---| | 1. Abduction: stance | Prosthesis too long Hip joint abducted Lateral wall inadequately adducted Medial wall too sharp or too high | Abduction contracture Weak abductors Lateral/distal pain Adductor redundancy instability | | 2. Circumduction: swing | Prosthesis too long Knee unit locked Friction insufficient Suspension inadequate Socket too small Socket too loose Foot plantar flexed | Abduction contracture Poor knee control | **Trunk Shifts** | | | | |---|---|---| | 1. Lateral bend: stance | Prosthesis too short Lateral wall inadequately adducted Medial wall too sharp or too high | Abduction contracture Weak abductors Hip pain Instability Short amputation limb Instability | | 2. Forward flexion: stance | Knee unit unstable Walker or crutches too short | | | 3. Lordships: stance | Socket inadequately flexed | | **Rotations** | | | | |---|---|---| | 1. Medial (or lateral) whip: heel of | Socket contour faulty Knee bolt externally (or internally) rotated Foot mal-rotated Prosthesis donned in malrotation | | | 2. Foot rotation at heel contact | Heel cushion too stiff Foot mal-rotated | | **Excessive Knee Motion** | | | | |---|---|---| | 1. High heel rise: early swing | Friction insufficient Extension aid slack | | | 2. Terminal impact: late swing | Friction insufficient Extension aid taut | | **Reduced Knee Motion** | | | | |---|---|---| | 1. Vault: swing | See above: circumduction | | | 2. Hip hike: swing | See above: circumduction | | **Uneven Step Length** | | | | |---|---|---| | | Socket uncomfortable Socket inadequately flexed | | **Note:** This table summarizes the data from the image.
