33
Q

true or false: loose packed for mobilizations is designed to reduce pain

A

true

34
Q

True or false: accessory motions (arthrokinematics) does not occur simultaneously with osteokinematic motions

A

false: it does occur simultaneously

35
Q

forces have

A

magnitude and direction so kinetics uses vectors

36
Q

longer arrows mean higher

A

magnitude

37
Q

direction of arrow is the direction of

A

force

38
Q

load/stress

A

tension, compression, bending, shear, torsion, combined laoding

39
Q

stress

A

internal resistance to deformation / x sectional area of tissue

40
Q

strain

A

percent elongation compared to pre stretch length

41
Q

Young’s modulus

A

ration of stress to deformation (strain) (Y/X) – measure of tissue stiffness or elasticity

42
Q

toe region

A

crimped or wavy fibers get straightened - very littles stress - resting phasee

43
Q

lastic region

A

temporary deformation

44
Q

plastic region

A

permanent deformation - more laced in tissue when loaded

45
Q

yield point

A

microscopic damage to tissues allows more elongation with little increase in stress - yield to stress and allowing deformation

46
Q

ultimate failure point

A

rupture of tissue (for healthy tendons, occurs at 8-13% elongation from pre stretch length)

47
Q

stress over strain is

A

stiffness

48
Q

small Y over Big X

A

strain -stretch

49
Q

big Y over small X

A

Stress - load

50
Q

historicist

A

you never hit the yield point but due to repetition you increase your resting length

51
Q

viscosity

A

a materials resistance to deformation at a given rate (result of reorganization of atoms/molecules) how sticky and thick the tissue is

52
Q

elasticity

A

a materials ability to immediately return to its original length after being stretched (result of atomic bond stretching)

53
Q

viscoelasticity

A

measure of a materials time dependent strain (change in stiffness as a function of time)
faster loading = increased stiffness

54
Q

higher load rate

A

steeper slope of curve (more stress with less formation due to viscoelasticity)

55
Q

increase temperature would

A

decease of stiffness (more ductile) shallow

56
Q

decrease temperature would

A

increase of stiffness (less. ductile) steeper

57
Q

creep

A

apply a load in a way that the tissue is allowed to constantly elongate under load
- constant stress (load)
- constant internal resistance to the load
- deformation (strain overs over time)
example: knee replace - prob heel up and but a heavy ice pack on top of the knee and let gravity stretch it out

58
Q

stress relaxation

A

tissue is put in a position of stretch, but the position is maintained with no potential for elongation
- constant length (strain) of tissue
- change in stress over time
- casting your elbow at a stretch position - overtime, building relaxation and then stretch and cast again

59
Q

serial casting is an example of

A

stress relaxation

60
Q

dynamic splinting is an example

A

stress or creep

61

internal forces is within:

the body (muscles)

62
Q

External forces is:

A

63

internal and external forces is represented by? and what do they have?

A

Vectors:
magnitude
orientation
direction
point of application

64
Q

torque

A

forces that induces rotation

65
Q

torque equation

A

MA x Force

66
Q

moment arm (MA)

A

perpendicular distance from axis to point of force application

67
Q

T or F: leverage - greater advantage with a longer moment arm because that force won’t have to be as high to get the same torque as a force with a shorter moment arm

A

True

68
Q

there is no torque if the force

A
  • pierces the axis of rotation (MA is zero)
  • parallels the axis of rotation (no perpendicular line of force)
69
Q

concentric

A

internal force is greater than external force

70
Q

eccentric

A

external force is greater than internal force

71
Q

isometric

A

EF and IF is equal to one another

72
Q

T or F: all muscle action does not cause JRF

A

False: it does cause JRF

73
Q

JRF compresses joint and creates?

A

stability

74
Q

force couples

A

multiple muscle contractions at different linear direction

75
Q

lever

A

converts linear force into rotary torque

76
Q

components of levers

A

rigid body
forces (IF/EF)
point of rotation (axis)

77
Q

T or F: the longer the MA, the more efficient the lever

A

true

78
Q

1st class lever

A

forces on either side (opposite torque)
fulcrum is in between
nodding yes!

79
Q

2nd class lever

A

External force is closer and greater than internal force (calf raises)

80
Q

3rd class lever

A

internal force is closer and greater than external force
(most muscles are 3rd class) bicep curl

81
Q

Second class characteristic

A

less force, motion, and speed

82
Q

third class characteristics

A

more force, motion, and speed
