how is gait generated? Correct Answer--Gait is performed at a
subconscious level
-Humans are bipedal (Learn to walk in ~first year of life)
-central patterns generated at s.c.
-changes over lifespan
gait Correct Answer--Achieving upright locomotion on foot
-Walk, run or jog
Locomotion Correct Answer-Moving from 1 place to another
-crawling, rolling across floor
-motion: transfer skill, hopping skipping
Ambulation Correct Answer--Type of locomotion
-Used clinically - with or without assistive device
--some kind of assistance to move one place to other
stride Correct Answer--Heel contact to heel contact of same lower
extremity
-Divided into 'Stance' and 'Swing' phases
-2 Terminology Systems - Traditional and Ranchos
-Normalized to 100%
-Stance = 60%; Swing = 40%
,-Normal walking speed - gait cycle lasts 1 second
-2 periods of double limb support:pelvic control
how many phases does stance and stride have? Correct Answer-
STANCE-5, 60%, uses a lot of momentum for accepting weight or
pushing forward-a lot of concentric
SWING-3, 40%-shortening limb, a lot of eccentric
step length Correct Answer-initial contact on one foot to initial contact
on contralateral foot
stride length Correct Answer-initial contact on one foot to that foot
-made up of 2 step lengths
step width Correct Answer--width b/w 2 feet
-don't measure to outside or inside borders
-try to eyeball middle of heel, bisecting the heel
-pretty narrow base of support
toe out Correct Answer-laterally rotated and eversion
gait cycle Correct Answer-rt. gait cycle has a right step lenth and left
step length
, Angle of Progression Correct Answer-take a line and mesasure middle
of heel and another line between 2nd and 3rd toe
-normal is 2-5 deg. outtoeing
-norms depend on leg length and height
velocity Correct Answer-how fast you walk
-normal relaxed walking=2.5 miles an hr.
-4 miles= fast walking
-running=no double support
step duration Correct Answer-how much time is person on there foot
during moving instance phase
cadence Correct Answer-how many steps per minute
phases of stance Correct Answer-1. Initial contact (IC)
2. Loading Response
3. Midstance
4. Terminal Stance
5. Preswing
Initial contact Correct Answer-heel makes contact with ground
-0 to 2% of time
