Phases
The point when the entire body is over the foot
What is mid-stance?
What are kinematics?
What is flexion?
This muscle fires eccentrically after initial contact to lower the foot to the ground
What is the tibialis anterior / ankle dorsiflexors?
This joint flexes and extends about 20 to 30 degrees throughout the gait cycle
What is the hip
This is the maximum VGRF by bodyweight
What is 110% BW
This Detroit-based rock group began in the early 70s, whose 4 rockers are known for their facial makeup; they are still touring today.
What is KISS?
These 2 phases share the same name in both standard and RLA terminology
What are mid stance and mid swing?
This task occurs when only one foot is on the ground at a time and occurs twice during a single gait cycle
What is single limb support?
During the stance phase, the ipsilateral arm should be moving in this direction
What is extension
This muscle eccentrically controls ankle dorsiflexion during the stance phase
What is the gastroc-soleus / calf?
60 degrees of knee flexion occurs at this phase
The VGRF peaks during this phase
What is early mid stance?
Terminal Stance
What is the forefoot rocker
Standard terminology for the phase just before the heel hits the ground at the end of the swing phase
What is deceleration?
The distance measured between right heel strike and left heel strike
The knee moves in this direction of motion during the swing phase.
What is extension?
The hamstrings fire eccentrically to slow knee extension during which phase?
What is terminal swing?
This joint remains neutral throughout swing phase, and extends at the end of the stance phase
What is the first MTP
At initial contact, the VGRF passes anterior to these 2 joints
What are the knee and hip
Pre Swing
What is the toe rocker
This phase begins with maximal knee flexion and ends when the tibia is perpendicular to the ground
What is initial swing
Typical cadence averages this per minute
What is about 100 to 120 steps per minute
The subtalar joint is in this position during the stance phase
What is neutral
A drop of the pelvis on the swing side indicates weakness of which muscle on the stance side?
What is the gluteus medius?
In the frontal plane and transverse planes, this joint deviates about 5 degrees in each direction, but varies little in the sagittal plane
What is the pelvis
The anterior tibial muscles counter the plantarflexor moment of the ankle at this phase
What is initial contact
Mid Stance
What is the ankle rocker
Running decreases the length of these 2 phases
What are the loading response (Foot Flat) and pre-swing phases (Toe off)?
The functional classification of activities from pre-swing to terminal swing
What is Swing Leg Advancement
During the swing phase, the pelvis should be rotating in this direction
What is forward?
Which muscles fire eccentrically during terminal swing to slow hip flexion?
What are the hamstrings?
This is normal pelvic rotation during the entire gait cycle
What is 8 to 10 degrees?
This muscle counteracts the medial VGRF in the frontal plane to maintain a level pelvis
What is the gluteus medius
Initial Stance
What is the heel rocker?
