Q
Initial Contact
A
- the beginning of the stance phase that occurs when the foot touches the ground
23
Q
Loading response
A
- corresponds to the amount of time between initial contact and the beginning of the swing phase for the other leg
24
Q
Midstance
A
-The point in stance phase when the other foot is off the floor until the body is directly over the stance limb
25
terminal stance
- begins when the heel of the stance limb rises and ends when the other foot touches the ground
26
pre-swing phase
- begins when the other foot touches the` ground and ends when the stance foot reaches toe off
27
Initial Swing:
- begins when the stance foot lifts from the floor and ends with maximal knee flexion during swing
28
midswing
begins with maximal knee flexion during swing and ends when the tibia is perpendicular with the ground
29
terminal swing
- begins when the tibia is perpendicular to the floor and ends when the foot touches teh ground
30
Heel strike
- is the instant that the heel touches the ground to begin stance phase
31
foot flat
- foot flat is the point in which the entire foot makes contact with the ground and should occur directly after heel strike
32
heel off
- point in which the heel of teh stance limb leaves the ground
33
toe off
- toe off is the point in which only the toe of teh stance limb remains on the ground
34
acceleration
- begins when toe off is complete and the reference limb swings until positioned directly under the body
35
deceleration
- begins directly after midswing, as the swing limb begins to extend, and ends just prior to heel strike
36
What percentage of gait cycle is stance phase? swing phase>
- stance phase represents 60% of the gait cycle
| - swing phase represents 40% of the gait cycle
37
Base of support
- the distance measured between teh left and right foot during progression of gait
- teh distance decreases as cadence incr
- the avg base of support for an adult is two to four nches
38
Cadence
- The number of steps an individual will walk over a period of time. the avg value for an adult is 110-120 steps per minute
39
degree of toe-out
the angle formed by each foot's line of progression and a line intersecting teh center of teh heel and second toe. the avg degree of toe-out for an adult is seven degrees
40
double support phase:
-double support phase refers to the two times during a gait cycle where both feet are on the ground. the time of double support incr as the speed of gait decr. this phase does not exist with running
41
pelvic rotation
- rotation of teh pelvis occurs opposite the thorax in orer to maintain balance and regulate speed. teh avg pelvic rotation during gait for an adult is a total of 8 deg
42
single support phase
- occurs when only one foot is on the ground and occurs twice during a single gait cycle
43
What muscle activity do we see in Initial Contact?
- The ankle DF place the ankle in DF during heel strike and prepare to lower the foot towards the ground.
- the quadriceps contract to place the knee in extension while teh hamstrings help stabilize the knee and prevent hyperextension
- The hip extensors and abductors contract to stabilize the trunk and pelvis over the leg
44
What muscle activity do we see in loading response
- The ankle DF act eccentrically to control lowering of teh foot towards the ground.
- the quadriceps contract eccentrically to control knee flexion as the limb accepts the weight of teh body.
- In the latter portion the plantarflexors eccentrically control DF as the tibia moves over the foot
- Simultaneously, the tibialis posterior eccentrically controls pronation of the foot
- the quadriceps contraction becomes concentric to draw the femur forward over the tibia
- throughout the loading response phase, the hip extensors contract concentrically to produce hip extension
45
What muscle activity do we see in midstance?
- the plantar flexorss continue to act eccentrically to control DF as teh body moves over teh stance limb. activity in the knee musculature is minimal during this phase, though the quads contract concentrically to continue producing closed chain knee extension.
- the hip abductors muscles stabilize the pelvis and prevent contralateral hip drop
- the iliopsoas also begins to contract eccentrically to control hip extension
46
What muscle activity do we see in terminal stance
- plantar flexors begin to work concentrically to aid the foot in its propulsion of teh body forward
- knee muscle activity remains limited
- the hip abductors continue to stabilize the pelvis and teh iliopsoas continues to slow the rate of hip extension
47
What muscle activity do we see in pre-swing?
- the plantar flexors are at their peak activity as teh foot"toes off" from the ground.
- the hamstrings begin to produce knee flexion to prepare for teh swing phase, though the momentum of teh body also aids in this motion.
- the iliopsoas begins to work concentrically to produce hip flexion, along with other hip flexors
48
What muscle activity do we see in initial swing
- andkle dorsiflexors contract concentrically to clear teh foot from the ground, while the hamstrings assist with foot clearance by flexing the knee.
- the hip flexors continue to produce hip flexion to advance the limb forward
49
What muscle activity do we see in midswing?
- ankle dorsiflexors continue to contrat concentrically to maintain DF.
- Knee and hip muscle activity ar eminimal during this phase since forward momentum allows for advancement of the limb
50
What muscle activity do we see in terminal swing?
- ankle Dorsiflexors continue to contract concentrically to maintain DF.
- the ankle invertors also contract concentrically to prepare the foot for initial contact
- The quads contract concentrically to place the knee in extension for initial contact, while the hamstrings act eccentrically to control the rate of knee extension. the hip extensors eccentrically slow the rate of hip flexion and prepare the limb for initial contact
