38
Q

What are the pros of using carbon fiber?

A

Strong
Flexible
Weight and Energy storing properties

39
Q

What are the roles of PTs in Ortho/Prosthe?

A

Identify the functional problems of the pt.
Identify orthotic needs
Prescribe orthoses according to pt’s problems
Educate the pt to don and doff the orthoses
Train for proper use

40
Q

What are the functions of Orthosis? (2)

A

Stabilizes unstable body segments
Assists weak ms
Stops undesired motions

41
Q

What does an orthotist do?

A

Healthcare profession that designs/modifies the orthotics for the pt.
Adjusts the device

42
Q

What is the primary purpose of all upper limb orthoses?

A

Substitute weak/absent ms
Protect, damaged, or diseased segments by limiting load
Prevention of deformity
Correction of contracture
Attachment of other AD.

43
Q

Anchor does not limit or assist motion

A

3-point control concept

44
Q

Biomechanical Principles

A

Three-point control concept
Tissue tolerance to compression and shear forces
The biomechanics of levers and forces
Selection of materials

45
Q

Biomechanism of the levers and forces

A

The farther the fulcrum from the end, the lesser the pressure on the segment

46
Q

How much pressure can be tolerated for 2-4 hours continuously?

A

100-300 mmHg

47
Q

How much pressure can be tolerated for 12 hours continuously?

A

20-50 mmHg

48
Q

What are the types of Orthoses?

A

Static
Dynamic
Hybrid

49
Q

What are the types of UE Orthoses?

A

Static
Serial Static
Static motion-blocking
Static progressive
Dynamic
Dynamic motion-blocking

50
Q

Provides support to a body part and does not cross any joint

A

Non-articular

51
Q

Provides static support to hold a joint or joints stationary.

52
Q

Non-articular orthosis used for a humeral fracture

A

Sarmiento brace

53
Q

Non-articular orthosis used for Wrist/Radial fracture

A

Sugar tong splint

54
Q

Static but is periodically changed to alter the joint angle at which the splint is positioned

A

Serial static

55
Q

What joints should be mobilized ASAP?

A

IP and MCP joints

56
Q

Why must IP and MCP joints be mobilized ASAP?

A

To prevent contracture or possible adhesions to the tendons

57
Q

How should the thumb be immobilized?

A

It must be immobilized in opposite to the fingers in palmar abduction

58
Q

Characteristics of a static orthosis

A

Has no movable joints
Allows active joint movement in one motion
Block motion in another direction

59
Q

Characteristics of a dynamic orthosis

A

Has movable joints that can limit motion
Increases motion through traction
Substitute for weak muscles`

60
Q

Characteristics of a hybrid orthosis

A

incorporates the features of both static and dynamic orthosis

61
Q

What does serial static orthosis provide to the affected structures?

A

A prolonged, gentle stretch

62
Q

What does static motion blocking do?

A

Allows motion in one direction but blocks motion in another

63
Q

Static motion-blocking orthosis is commonly used in what deformity?

64
Q

An orthosis that allows flexion but blocks the extension of the PIP

A

Swan neck splint

65
Q

Provides an elastic force to regain motion

A

Static progressive

66
Q

What is the distinguishing characteristic of static progressive?

A

It is not remodeled and already has adjustable parts

67
Q

Provides elastic force

68
Q

What is the use of the spring in a Capener splint?

A

Increases PIP joint extension to prevent mild contracture

69
Q

Utilizes a passive, elastic line of pull in the desired direction but permits active motion in the
opposite direction

A

Dynamic motion blocking

70
Q

An example of a dynamic motion blocking orthosis

A

Kleinert splint

71
Q

When is Kleinert splint used?

72
Q

What is the function of a Kleinert splint?
