10.0 Pathological Gait: Hip Flashcards
When is the Intra Articular Pressure Greatest in the hip?
0° of Flexion
What is the open packed position of the hip?
30-60° of flexion
This is known as losing the ability to extend the hip at certain degrees.
Hip Flexion contracture
This is known as failure to achieve normal amount of flexion
Inadequate Flexion
This is coined as having more than normal range of motion at the hip
Excessive Hip Flexion
this is known as persistent hip flexion when the hip should be extending
Inadequate Extension
During Loading Response, What are some potential causes for Inadequate Hip Flexion?
- Quadriceps Weakness
- Hip Extensor Weakness
- Decreased Heel Rocker
What are the penalties for Inadequate hip flexion during loading response, possibly due to weak quadriceps, hip extensors, or decrease of heel rocker?
Decreased Shock Absorption at the knee
Increased bone and cartilage loading
What are some potential causes for inadequate hip flexion during Pre-swing, Initial-swing, and Mid-Swing?
- Hip Flexor Weakness
2. Muscle or Joint Pain (Avoidance)
What are the penalties associated with Inadequate hip flexion during Pre-swing, Initial-swing, and Mid-swing, possibly caused by hip flexor weakness, or avoidance from muscle or joint pain?
- Decreased Limb advancement
- Decreased Stride Length
- Decreased Foot Clearance
What is a compensatory strategy for inadequate hip flexion?
- Excessive knee Flexion
2. Circumduction
What are some potential causes for excessive hip flexion during Pre-swing, Initial-Swing, and Mid-swing?
- Compensatory Strategy to clear foot
- Excessive Plantarflexion
- Inadequate knee flexion
What is the penalty associated with Excessive hip flexion through pre-swing to mid-swing caused by a compensatory strategy to clear the foot?
Increased Energy expenditure related to muscle overuse
-(Hip flexors)
This is a rapid hip flexion couple with a quick deceleration, which causes the tibia to snap into extension.
Past-Retract Maneuver
What are the potential causes of inadequate hip extension in Mid-stance and Terminal-stance
- Hip Flexor tightness
- Hip Flexion Contracture
- Knee Flexion Contracture
What are the penalties associated with inadequate hip extension, caused potentially by Hip flexor tightness, hip flexor contracture, and knee flexion contracture?
Reduced Stride Length
What are some compensations for inadequate hip extension?
Excessive Anterior Pelvis Tilt
Backward Rotation
A hip flexion contracture could cause what about the trunk?
Increased Lumbar Lordosis
What are some causes for excessive hip Adduction during the stance phase of the Gait cycle?
Hip Abductor Weakness
What are the penalties associated with excessive hip adduction during the stance phases, caused by hip abductor weakness?
Joint/soft Tissue Strain
- IT Band Strain
- Lateral hip Pain
- Medial Knee Strain
What are the causes of excessive pelvic drop during the stance phases of the gait cycle?
-Hip Abductor Weakness
What are the penalties associated with Excessive Pelvic Drop?
- Increased Knee Stress
- Varus moment - Increased Spine Stress
- Facet Joint Compression - Muscle Overuse
- Paraspinals
- Quadratus Lumborum
A compensation about the trunk due to hip abductor weakness is?
Contralateral Lateral Trunk Lean
What are the potential causes of Excessive Hip Rotation during the stance phases of the Gait cycle?
- Excessive Pronation
2. Weakness of hip External rotators
What are the penalties associated with Excessive hip rotation about the stance phases due to excessive pronation and weakness of hip external rotators?
- Knee Joint Stress/Strain
- MCL Stress
- Pen Anserine Strain
- IT Band Strain - Patellofemoral Joint Stress
Which muscles are of influence for Gait pathologies about the hip?
Hip Extensors
Hip Flexors
Hip Abductors
