POAT FINAL TTA Gait Deviations
TTA: What are some prosthetic causes of excessive knee flexion in early stance? -
answer- Heel height too high
- Excessive ankle DF
- Stiff Heel Cushion
- Socket too far anterior
- Socket excessively flexed
- Cuff brim too posterior
- Prosthesis too long
TTA: What are some anatomical causes of excessive knee flexion in early stance? -
answer- Knee/hip flexion contracture
- Quad weakness
- Pain anteriorly in residual limb
- Poor balance
TTA: What is the functional significance of excessive knee flexion in early stance? -
answer Impaired shock absorption
Increased demand on quads to prevent further knee flexion
TTA: What are some prosthetic causes of insufficient knee flexion in early stance? -
answer- Low shoe heel
- Excessive ankle PF
- Soft heel cushion
- socket too far posterior
- Socket insufficiently flexed
TTA: What are some anatomical causes of insufficient knee flexion in early stance? -
answer- Extensor spasticity
- Weak Quads
- Anterior-Distal RL pain
- Arthritis
TTA: What is the functional significance of insufficient knee flexion in early stance? -
answer- Reliance on bony structures stance stability
- Insufficient shock absorption
TTA: Prosthetic causes of lateral/varus thrust at midstance? - answer- Excessive foot
