Gait: part 1 Flashcards
what does weight acceptance allow for? what are the goals?
transfers weight from one leg to another
allows for shock absorption, forward progression, and stability
what is the most difficult task of gait?
weight acceptance
what occurs during single limb support? what are the goals?
stability of leg while body advances over it
forward progression and stability
what occurs during swing limb advancement? what are the goals?
unload the leg and advance it forward
goals = foot clearance and limb advancement
define speed
distance per unit time
define cadence.
number of steps per minute
what is the normal range of speed for maleS?
1.36m/s
what is the normal range of speed for females?
1.32m/s
what is the normal range of cadence for females?
121 steps/minute
what is the normal range of cadence for males?
111 steps/minute
what can change, step lengths or stride lengths?
step lengths
which distance measures are along the sagittal plane?
stride length
step length
toe out
what is the normal stride length for males?
1.48 meters
what is the normal stride length for females?
1.32 meters
what is the most sensitive to gait improvement?
speed
what is decreased speed associated with?
disease, decline in functional status, balance deficits
why is speed considered an important temporal measure to achieve?
because decreased speed may suggest damage to the MSK, cardiovascular, and neurological systems
speed, cadence, and stride length are all influenced by what?
height and gender
what does a longer limb length mean?
longer stride length
what should you do in order to increase speed?
increase cadence and stride length
what should you do to achieve a very high speed?
increase cadence because stride length will plateau
what two temporal measures start decreasing after age 70?
speed and stride length
what is the normal step width?
8 cm
what is the normal foot angle?
7 degrees
what do step width and foot angle determine?
BOS
