Locomotion:
Walking
Walking
The period of support during the gait cycle.
What is stance?
During running this is what the leg functions as.
What is a spring?
+1 Point Exam
Foot strike of one foot to next foot strike of same foot.
What is a stride?
This allows material to return to its original shape after deformation.
What is elasticity?
A search for the limits of stability.
What is postural sway?
This phase of gait occurs 75-85% of the way through the gait cycle.
What is mid-swing?
+1 Point Exam
The phase of running at which COM is at its highest point.
What is the flight phase?
The region in which tendon stretches without much force.
What is the toe region?
+1 Point Exam
The law used to model spring like properties.
What is Hooke's Law?
The point where force from support surface is applied to the body.
What is the Center of Pressure?
The purpose of this phase of gait is foot clearance.
What is initial swing?
What is 50%?
The name of the number that cannot be greater than 1 if a person is considered to still be walking.
What is Froude's number?
The difference in energy loaded and unloaded.
What is hysteresis?
+1 Point Exam
This reaction strategy uses distal to proximal muscle recruitment and small, slow perturbations.
What is ankle strategy?
+1 Point Exam
During this phase of gait the GMAX, TFL and GMed are all active.
What is loading response?
Most work during running is to displace this vertically and forward.
What is COM?
Movement in the opposite direction before moving in the required direction.
What is the stretch-shortening cycle?
The percentage of energy that can be returned when a tendon is unloaded.
What is 90-96%?
This system is involved with the head's orientation with respect to gravity
What is the vestibular system?
This phase of gait is when maximum hip extension occurs.
What is terminal stance?
What is the Inverted Pendulum Model?
A reaction strategy that uses proximal to distal muscle recruitment and large, quick perturbations?
What is hip strategy?
+1 Point Exam
2-5% of this occurs during the linear region.
What is physiological strain?
When this senses stretch in musculotendinous junction, it will cause muscle contraction to correct postural deviation.
What is the golgi tendon organ?
