A

1.) Abduction2.) Adduction3.) Side flexion of the trunk4.) Shoulder elevation5.) Shoulder depression6.) Radial deviation of the wrist7.) Ulnar deviation of the wrist8.) Eversion of the foot9.) Inversion of the foot

24
Q

What movement occur in the transverse plane around the longitudinal axis?

A

1.) Rotation of head, neck & trunk2.) Internal rotation of arm or leg3.) External rotation of arm or leg4.) Horizontal adduction of arm or thigh5.) Horizontal abduction of arm or thigh6.) Pronation of the forearm7.) Supination of the forearm

25
Q

What combination of movements does circumduction as a whole incorporate?

A

1.) Flexion2.) Extension3.) Abduction4.) Adduction

26
Q

What does circumduction involve?

A

An orderly sequence of circular movements that occur in the sagittal, frontal and oblique planes

27
Q

What is kinematics?

A

The study of motion

28
Q

What are the 2 types of motion involved in kinematics?

A

1.) Osteokinematic motion2.) Arthrokinematic motion

29
Q

What is osteokinematic motion?

A

Occurs when any object forms the radius of an imaginary circle about a fixed point

30
Q

How is the axis of rotation or osteokinematic motion oriented?

A

Perpendicular to the plane in which the rotation occurs

31
Q

What are some examples of osteokinematic motion?

A

1.) Abduction/adduction of the arm2.) Flexion of the hip or knee3.) Side flexion of the trunk

32
Q

What is arthrokinematic motion?

A

The motions occurring at joint surfaces

33
Q

What determines the direction of movement in arthrokinematic motion?

A

Direction of movement is based on the shape of the joint surfaces

34
Q

What is the shape of joint surfaces?

A

1.) Concave2.) Convex3.) Sellar (Concave and convex)

35
Q

What is the shape of joint surfaces?

A

1.) Concave2.) Convex3.) Sellar (Concave and convex)

36
Q

What are 3 types of movement that occur at the articulating surfaces?

A

1.) Roll2.) Slide3.) Spin

37
Q

How is osteokinematic motion and arthrokinematic motion related to each other?

A

1.) They are directly proportional to each other2.) One cannot occur completely without the other3.) If motion is reduced, one or both of the motions are at fault

38
Q

What are degrees of freedom (DOF)?

A

The number of independent modes of motion st a joint

39
Q

What is the close-packed position of a joint?

A

1.) The position of maximum congruity of the opposing joint surface2.) Position of maximum joint stability

40
Q

Movements toward the close-packed position of a joint involve what element?

A

Joint compression (approximation)

41
Q

What does further movement of a joint in the direction of the close-packed position where by the capsule and ligaments are taut, results in?

A

Fracture or dislocation

42
Q

What is the open-packed position of a joint?

A

1.) The position of least joint congruity2.) Position of least joint stability

43
Q

Movements toward the open-packed position of a joint involve what element?

A

Joint distraction (separation)

44
Q

What does further movement of a joint in the direction of open-packed position where by the capsule and ligaments are not taut, results in?

A

Sprain or strain

45
Q

What is a hypomobile joint?

A

If a joint moves less than what is considered normal, or when compared to the same joint on the opposite extremity

46
Q

What is a hypermobile joint?

A

A joint that moves more than considered normal, or when compared to the same joint on the opposite extremity

47
Q

What does instability of a joint involve?

A

Disruption of the osseous and ligamentous structures of that joint, resulting in a loss of function

48
Q

What are the factors of joint integrity?

A

1.) Elastic energy2.) Passive stiffness3.) Muscle activation

49
Q

How does elastic energy affect joint integrity?

A

Stored NRG allows elastic tissue to return to original

50
Q

When is passive stiffness found?

A

Found at the end of range of motion

51
Q

What happens with incorrect synergistic and antagonistic balance, both in timing and strength of muscle activation?

A

Buckling or shear translation

52
Q

What is a loss of passive stiffness called?

A

Laxity

53
Q

What are some examples of external forces?

A

1.) Ground reaction force2.) Friction3.) Gravity

54
Q

What are some examples of internal forces?

A

1.) Muscle contraction2.) Joint contact3.) Joint shear forces

55
Q

If musculoskeletal health is to be maintained, what must tissues be able to demonstrate the ability to withstand?

A

Excessive or repetitive stress

56
Q

The capacity of tissue to withstand stress is dependent on what factors?

A

1.) Age2.) The proteoglycan & collagen content of the tissue3.) The ability of the tissue to undergo adaptive change4.) The speed at which the adaptive change must occur - depends on the type and sevarity of insult to tissue
