It's about Time
The number of steps per unit of time
What is Cadence?
This is when Mid stance ends
What is 30% of the gait cycle or when bodyweight travels forward over the forefoot?
The talus movement at loading response.
What is anterior slide?
The direction of ground reaction impulse force during initial contact.
What is posteriorly?
This muscle helps control forward trunk momentum and balance during early stance.
What is the erector spinae?
60% of the time.
The is the amount of time the lower extremity is in the stance phase?
When heel rise begins.
What is 30-50% of gait cycle, when body weight moves center of mass anterior to the foot, or the beginning of 3rd rocker?
The direction the right acetabulum is moving during left swing.
What is moving anteriorly?
The direction of ground reaction force impulse at terminal stance.
What is anteriorly?
This muscle group activates during loading response to eccentrically control plantarflexion.
What is the tibialis anterior or pretibial muscles?
2 x 10% of the time
What is the amount of time one is in double limb support?
When the contralateral side hits the ground?
What is the end of terminal stance, the beginning of pre-swing, the beginning of the second double limb support, occurs at about 50% of the gait cycle?
The direction the tibia is moving during initial swing.
What is posteriorly sliding?
What is the force at the knee during loading response.
What is into flexion?
These muscles stabilize the foot during midstance to prepare for heel lift in terminal stance.
What are the intrinsic foot muscles?
About 15% of the time
What is the amount of time needed for Initial Swing or mid-swing?
This happens when the tibia is vertical.
What is when mid swing ends or when terminal swing begins? Could also be what is the end of heel rocker?
The direction the femur is moving during mid-swing phase.
What is posteriorly?
The direction of hip external torque at loading response.
What is into hip flexion?
This hip adductor muscle activates in two bursts: at initial contact and again in initial swing.
What is the adductor magnus?
1/50th of the gait cycle
About how much of the time is the body performing Initial Contact?
When swing ends.
What is 100% of the gait cycle or 0% at initial contact?
The direction the right femur is moving during swing phase.
What is sliding anteriorly and externally rotating?
The direction of external torque at the trunk during loading response.
What is trunk flexion?
This muscle controls pelvic tilt during single-leg stance, ensuring that the pelvis stays level.
What is the gluteus medius?
