Patho - Hip Flashcards
Inadequate Hip Flexion
Failure to achieve normal amount of flexion.
Excessive Hip Flexion
More than normal range.
Inadequate Hip Extension
Persistent hip flexion when the hip should be extending.
Inadequate Hip Flexion - Loading Response Causes
Quadriceps Weakness
Hip Extensor weakness
Decreased Heel Rocker
Inadequate Hip Flexion - Loading Response Penalties
Decreased Shock Absorption at the knee (Increased Bone and Cartilage Loading).
Inadequate Hip Flexion - Pre-swing, Initial Swing and Mid-Swing Causes
Hip Flexor Weakness
Muscle or Joint Pain (avoidance)
Inadequate Hip Flexion - Pre-swing, Initial Swing and Mid-Swing Penalties
Decreased Limb Advancement
Decreased Stride Length
Decreased Foot Clearance
Excessive Knee Flexion and Circumduction is a compensatory strategy for inadequate hip flexion.
Excessive Hip Flexion - Pre-Swing, Initial Swing and Mid-Swing Causes
Compensatory Strategy to Clear Foot - From excessive plantarflexion and/or inadequate knee flexion.
Excessive Hip Flexion - Pre-Swing, Initial Swing and Mid-Swing Penalties
Increased Energy Expenditure Related to Muscle Overuse - Hip Flexors
Past-Retract Maneuver
A compensatory strategy to extend the knee in terminal swing.
A dynamic event to achieve knee extension in terminal swing. A rapid hip flexion with a quick (Snap) hip extension allowing the knee to snap into extension. Done in patients with weal quads or prothesis’s.
Inadequate Hip Extension - Midstance and Terminal Stance Causes
Hip Flexor Tightness
Hip Flexion Contracture
Knee Flexion Contracture
Inadequate Hip Extension - Midstance and Terminal Stance Penalties
Reduced Stride Length
Excessive Anterior Pelvic Tilt and Backward Rotation
Compensations for Inadequate Hip Extension
Excessive Hip Adduction - Stance Phases Causes
Hip Abductor Weakness
Excessive Hip Adduction - Stance Phases Penalties
Increased Knee Stress - Varus Moment
Increased spine Stress - Facet Joint Compression
