Jeopardy Kines exam 3

Identify the osteokinematic occurring at the hip in the transverse plane during midstance

Internal rotation

This is the longitudinal distance between initial contact on the right leg to intitial contact on the left leg

Step length

Which muscle is responsible for moving the ankle in the frontal plane during pre-swing?

Tibialis Posterior

In which phase of gait does the third rocker occur?

Terminal stance (at the beginning)

What phase of the gait cycle ends when the contralateral limb is lifted off of the ground?

Loading response

This is the horizontal distance between the heel centers of two consecutive heel contacts

Step width

Identify the osteokinematic occurring at the hip in the sagittal plane during terminal stance.

Hip extension

This is the number os steps per unit of time (i.e. steps per minute)

Cadence

This is the force that is created by the ground when a force is applied to it

Ground reaction force

Identify the osteokinematic occurring in the frontal plane at the hip during the first part of midstance.

Adduction

During which percentages of the gait cycle is an individual in midstance

10-30%

Which muscle group is most active to control the sagittal plane motion at the ankle during loading response?

Dorsiflexors

Which muscle group is active concentrically to move the hip in the sagittal plane in initial swing

hip flexor

During which phase in the gait cycle will an individual possess the greatest amount of potential energy?

Midstance

This is the longitudinal distance between initial contact on the right leg and the next initial contact on the right leg

Stride length

Identify the osteokinematic occuring in the frontal plane in the ankle during the second half of terminal stance

inversion

In which phase of the gait cycle would an individual with limited knee flexion have the most difficulty?

Late initial swing/early mid swing

What type of contraction are the quadriceps performing during loading response?

eccentric

What phase of the gait cycle begins when the swing is next to the contralateral foot?

midswing

Which muscle group is active eccentrically to control frontal plane motion of the hip in loading response and midstance?

Hip abductors

Identify the two portions of the gait cycle where an individual is in double limb support.

0-10% & 50-60%

Which muscle group eccentrically controls the rate of dorsiflexion during midstance and terminal stance?

Plantarflexors

Identify the osteokinematic occurring at the knee in the sagittal plane during loading response.

Knee flexion

Around which percentage of the gait cycle does the heel begin to rise?

~30%

In which phase of the gait cycle would an individual with significant limitation in ankle dorsiflexion ROM have the most difficulty?

terminal stance
