Dynamic Gait

Question 1

advantages of Treadmill gait

Answer 1

-small space requirement
-availability of weight support for pt. safety
-increasing sophistication of instrumentation

Question 2

disadvantages of treadmill gait

Answer 2

-higher cadence
-shorter stance times
-differences in joint ROM roughly 2.5 deg

Question 3

stair climbing

Answer 3

relatively simalir to walking

LEs must balance and carry extremities and head

stance 64% swing 36%

Question 4

Difference in stair climbing and ground walking ?

Answer 4

adequate muscle strenght and joint ROM for level ground walking does not ensure patient can ambulate stairs

ROM needed : 90-120 deg

this difference is seen in pathological patients

Question 5

In general joints perform two things in stair climbing

Answer 5

generative-stair ascent
absoptive-stair descent

Question 6

stance phase of stair climbing

Answer 6

weight acceptance
pull up
forward continuence

Question 7

swing phase of stair climbing

Answer 7

foot clearance
foot placement

Question 8

what else is required for stair climbing ?

Answer 8

increased muscle force to raise body against gravity

increased him and knee flexion in initial portion

Question 9

Running gait

Answer 9

requires greater balance , muscle strength, and ROM than normal walking

decreased BOS and double limb stance

muscles and joint stuctures must also be able to absorb more energy to accept and control weight

GRFs at initial contact> 200 to 250% of BW

Question 10

3 phases of running gait ?

Answer 10

stance 40%
swing 40%
float 20%

Question 11

effects of aging on gait

Answer 11

age of when gait starts is variable typically 12-17 months

after age 62: there is a 16 and 12% decline in walking speed in men and women

50% of older people were able to walk before a hip are not able to walk or live independtly following fracture

Question 12

toddlers have …

Answer 12

higher COM
wider BOS
decreased leg support time
shorter step length
slower velocity
higher cadence
