gait Flashcards
define gait
translatory progression of the body as a whole, produced by coordinated, rotatory movements of body segments
what age are these gait patterns most common in:
- high guard
- flat foot strike
- short steps
- fast gait
1 year
when can kids typically walk on tip toes and hop around
2-3 years old
when can kids typically begin to walk more naturally with a heel strike and maybe even “run”
18 months
at what age to kids develop a gait pattern similar to adults
7 years old
what joint does sagittal torque occur in gait initiation
ankles
how long does gait initiation occur
0.64 seconds
in the gait cycle we spend __% time in stance + ___% in swing
60% stance
40% swing
what is considered stance phase in gate
heel strike (initial) to toe off (pre swing)
anytime foot is touching the ground
what is considered swing phase in gate
toe off to heel strike
anytime the foot is traveling in mid air
stance phase steps (5)
- initial contact (heel strike)
- loading response
- midstance (foot flat)
- terminal stance (heel off)
- pre-swing (toe off)
swing phase steps (3)
- initial swing (acceleration)
- mid-swing
- terminal swing (deceleration)
how to measure LEFT step length
right heel strike to left heel strike
what measurement would you take for assessing gait symmetry
L + R step length
measurement of linear distance between mid heels
step width
how to measure stride length
heel strike to heel strike
ex: L heel to next L heel strike
measurement of the angle between line of progression between heels and 2nd toe
toe out
inverse dynamics
using segment kinematics and external forces applied to the body estimate “what must have occurred internally”
muscle use, unuse, ligament strain, etc
gait endurance test
6 min walk test
gait speed test
10 meter walk test
degree of hip, knee, + ankle in INITIAL CONTACT and what muscles are involved
hip: 20* flexion
knee: 5* flexion
ankle: 0*
