Flashcards in Biomechanical Standing Posture Analysis Deck (40):
1

having bones, capsules, and ligaments are inert so they are the most blank stability structures

energy efficient

2

most important postural muscle in leg

soleus

3

maintaining stability of the body in response to forces placed on it

postural control

4

postural control is both blank and blank

sensory, mechanical

5

postural control needs blank such as CNS, visual, vestibular, musculoskeletal

multi system contribution

6

two responses of postural control

reactive (compensatory), proactive (anticipatory)

7

task specific and vary with magnitude, velocity, and direction of force and initial posture of individual at time

postural strategies/synergies

8

grfv stands for

gravity reaction force vector

9

grfv and gravity =

line of gravity

10

point of application of grfv is at blank

center of pressure

11

line of gravity directly through joint axis causes blank torque

zero

12

if line of gravity is anterior to joint axis, the blank is anterior motion of the blank segment

moment, proximal

13

constantly changing blank postural sway

2 degree

14

plumbline represents blank

line of gravity

15

line of gravity of ankle is anterior to blank

lateral malleolus

16

the blank counteracts a dorsiflexion moment

soleus

17

a blank structure counteracts a moment

check rein

18

normal line of gravity of knee is blank to the axis

anterior

19

there is a blank moment at the knee normally

extension

20

the counteracting structure of extension of the knee in normal standing position is a flexion moment at the blank

posterior capsule

21

line of gravity is blank to the axis of the hip (greater trochanter)

posterior

22

gravity causes a blank moment at the pelvis

extension

23

what counteracts gravity at the pelvis

iliofemoral, pubofemoral, ischiofemoral

24

line of gravity is blank to axis of si joint

anterior

25

nutation is the same as blank but for si joint

flexion

26

there is a blank moment at the si joint

nutation

27

lumbar spine has a blank line of gravity normally

posterior

28

there is a slight blank moment at the lumbar spine

extension

29

lumbar spine extension moment is counteracted by blank

anterior longitudinal ligament

30

thoracic spine has a blank line of gravity normally

anterior

31

there is a blank moment at the thoracic spine

flexion

32

two counteracters of flexion of thoracic spine

posterior longitudinal ligament, ligamenta flava

33

cervical spine has a blank line of gravity normally

posterior

34

there is a blank moment at the cervical spine

extension

35

counteracter of flexion of cervical spine

ALL

36

oa and aa joints has a blank line of gravity normally

anterior

37

there is a blank moment at the oa and aa joint

flexion

38

counteracter of flexion of cervical spine

tectorial membrane

39

forward head (protrusion) creates increased blank of upper cervical and increased blank of lower cervical

lordosis (extension), kyphosis (flexion)

40

rounded shoulders caused by blank and blank of scapula

abduction, downward rotation
