|
What are the phases of the gait cycle?
|
Stance phase (60%)
Swing Phase (40%) |
|
|
What are the major stabilizers of the gait cycle?
|
Gluteus medius and minimus
Triceps Surae |
|
|
What are the forces involved in gait cycle (ambulation)?
|
Gravity
Momentum Muscle Contraction Elastic Recoil |
|
|
What propels the body forward when walking?
|
force of ground against feet, ie gravity
|
|
|
T/F: walking in snow with low friction requires greater muscle contraction/work
|
TRUE
|
|
|
What generates the forward propulsion particularly in the initial swing phase?
|
momentum
|
|
|
80% of the propulsion in the initial swing phase is due to what?
|
gravity plus momentum
|
|
|
What initiates gait motion?
|
muscle contraction
|
|
|
80% of the force in the second half of the swing phase is from what?
|
muscle contraction
|
|
|
Define Elastic Recoil, of the forces that contribute to gait cycle
|
Potential energy stored in the elastic tissue of the thoraclumbar fascia which provides a musculotendonous cross-bracing
|
|
|
How does symmetric gait conserve resources for humans?
|
Cross patterning: arm swing balances the rotation of the pelvis
Elastic recoil of connective tissue |
|
|
How does the pelvis move in the gait cycle?
|
Right foot steps forward:
Right inominate rotates anteriorly Left inominate rotates posteriorly |
|
|
How does the sacrum move in the gait cycle?
|
Right foot steps forward
Sacrum moves left = left on left sacral torsion results |
|
|
How does the lumbar spine move in the gait cycle?
|
Right foot steps forward
Lumbar side-bending left, rotation right |
|
|
Weight bearing change is accompanied by shift of sacrum from what axis to what axis?
|
Weight bearing change is accompanied by shift of sacrum from oblique axis to oblique axis
|
|
|
Which is more important for diagnosis and treatment: motion or mobility restrictions of body structures or static postural findings?
|
Motion or mobility restrictions of body structures
(gait is a really good test to Dx neurological problems) |
|
|
How can a somatic dysfunction in the lower extremity affect gait?
How can a somatic dysfunction in the pelvis affect gait? How can a somatic dysfunction in the sacrum affect gait? |
ex = short leg etc.
|
|
|
Whats the physiologic spot that doesn't move when you walk?
|
L3
If anything else doesn't move, its pathophysiological. Energy is wasted when anything other than L3 is the fulcrum |
|
|
Types of gait abnormalities
|
Antalgic (painful joint)
Compensated (ex = scoliosis) Decompensated (neurological problems ie Duchennes) |
|
|
Injury to anterior part of leg causes what gait abnormality?
|
foot drop
|
