Gait Cycle
A term used to refer to the gait cycle event when the foot first leaves the ground.
Acceleration or Initial Swing
The distance between the feet during gait, also referred to as base of support.
Step width
The muscle responsible for a level pelvis in single limb stance.
What is the hip abductor?
This event is often referred to as the loading response phase
What is foot flat?
This is a swing phase gait deviation where the limb swings in a semi-circular arch
What is hip circumduction?
The 0% point of the gait cycle, the beginning of gait.
What is initial contact or heel strike?
Cadence
The muscle that concentrically activates to propel the limb from stance into swing phase in heel off.
What are the plantarflexors?
The phase of gait where the stance limb hip is in 10 degrees of extension
What is Heel off?
This phase of the swing cycle is where the hamstrings activate eccentrically to slow the knee motion.
What is terminal swing or deceleration?
When the center of gravity is lowest and the body is in maximum stability in the first and last 10% of the gait cycle
What is double-limb support?
The distance of the same foot's heel strike during the gait cycle
Stride length
The only phase of gait where the dorsiflexors are activated eccentricaly.
What is foot flat?
The two sub phases of gait that encompass single limb support
This gait deviation occurs in the swing limb and looks like excessive elevation of the pelvis
What is hip hiking gait?
The maximum amount of knee flexion achieved during mid-swing.
Up to 60 deg
This knee motion causes the knee to become shortened for swing phase
Knee flexion
The phase of gait where the dorsiflexors are activated concentrically for foot clearance.
What is initial swing?
This muscle's activation increases significantly with increased speed or slope of walking during mid stance.
What is the glute max?
This corresponds to the mid stance phase of the contralateral limb.
What is mid swing?
This imaginary line directly indicates which muscle is active during stance phase in order to keep the body upright
Line of Gravity
This combination of knee motion and ankle motion cause the limb to be the longest that it can possibly be
Knee extension and ankle plantarflexion
The window of the gait cycle where the hip flexors are activated concentrically to advance the limb forward.
What is toe off to mid swing?
This is the final event of stance phase, at the 60% mark of the full gait cycle.
What is toe off or pre swing?
The angle of hip flexion from mid to terminal swing.
What is 20 degrees?
