Gait Flashcards
Gastroc- soleus
Responsible for concentric raising of the heel during toe off
2 periods of peak activity. Single support during early stance and just before toe off to initiate swing phase.
Quads
Hamstrings
Late swing phase, responsible for decelerating the unsupported limb.
Distance measured between L and R foot during progression of gait.
Average = 2-4”
BOS
Cadence
# of steps an individual will walk over a period of time. Average = 110-120 steps per minute
Degree of toe out
The angle formed by each foots line of progression and a line intersecting the center of the heel and second toe.
Average - 7 degrees
Double support phase
Refers to the 2 times during gait cycle where both feet are on the ground. Time increases as speed increases.
Not exist with running
The sequence of motions that occur from initial contact of the heel to the next consecutive initial contact of the same heel
Gait cycle
Pelvic rotation
Rotation of the pelvis occurs opposite the thorax in order to maintain balance and regulate speed. The average pelvic rotation during gait for an adult is 8 degrees, 4 degrees forward with swing leg and 4 backward with stance leg.
Occurs when one foot is on the ground and occurs twice during a single gait cycle
Single support phase
Step length
Distance measured between right heel strike and left heel strike.
Average - 28”
Stride length
Distance between right heel strike and the following right heel strike
Average - 56”
Anterior tib
Responsible For eccentric lowering of the foot into PF
High stepping ataxic gait pattern in which the feet slap the ground
Tabetic
Swing leg advances by compensating through combination of elevation of the pelvis and PF of stance leg
Vaulting –77
