  2. Pre-cut thermoplastic
  3. Pre-formed or pre-fabricated orthosis (thermoplastic neoprene with rigid, semi-rigid, flexible support)
72
Q

What are the four categories of basic types of orthosis?

A
  1. Static
  2. Serial static
  3. Static progressive
  4. Dynamic
73
Q

Explain a static orthoses.

A

No moving parts - used to support, stabilize, protect and immobilize. Can be pre-fabricated or custom fabricated.

74
Q

Explain serial static orthoses.

A

Used to lengthen tissues and regain passive ROM by placing tissues in a elongated position for prolonged periods.

75
Q

Explain static progressive orthoses.

A

Use nondynamic (non-elastic) components such as velcro, hinges, screws, or turnbuckles, to create mobilizing force to ROM. Allows the client to make small incremental changes in joint position as the PROM of the stiff joint slowly gives way.

76
Q

Explain dynamic orthoses.

A

Use moving parts to permit, control, or restore movement. Used to apply intermittent gentle force with goal of lengthening tissues to restore ROM.

77
Q

For protection, support, positioning of the hand, decreasing pain and inflammation, preventing undesired motion, substitution for impaired muscle function, providing positive pressure over scar, and/or to maintain gains in ROM following exercise/surgery, what type of orthosis would you recommend.

A

Static, to immobilize or stabilize joints.

78
Q

To immobilize or stabilize joints, what type of orthosis would you use?

A

Static

79
Q

To mobilize stiff joints, what type of orthosis would you suggest?

A

Serial static.

80
Q

To resolve muscle tendon tightness what type of orthosis may be beneficial?

A

Serial static.

81
Q

To stretch skin and soft tissue scar, what type of orthosis would be the most beneficial?

A

Serial static.

82
Q

To mobilize or provide distraction/traction to joints what type of orthosis should be used?

A

Dynamic.

83
Q

To mobilize stiff joints, resolve muscle tendon tightness, mobilize tendon adhesions, stretch skin and soft tissue scar, and/or to provide assistive motion to reconstructed joint/tendons and musculature what type of orthosis should be used?

A

Dynamic.

84
Q

The over-arching goal of orthoses is…

A

Patient’s return to function.

85
Q

What considerations guide orthosis selection?

A

Diagnosis may direct purpose of orthosis (physiological/biological impairments, healing), anatomic and physiological needs, holistic approach (therapeutic principles), psychosocial needs.

86
Q

Explain the stress-strain curve (load-deformation curve)

A

The relationship between the amount of stress applied to the tissue(s) and the amount of deformation or strain that occurs as a result.

87
Q

The longer a joint is positioned at its end range, the greater the gain in ____________________. Optimal deformation occurs with the application of low-load prolonged stress over a long period.

A

Passive range of motion.

88
Q

Why does passive range increase when the joint is positioned at its end range for an extended period of time but the active range of motion does not?

A

When a joint is positioned at its end range for an extended period of time, such as during prolonged stretching or immobilization, the passive structures around the joint, including ligaments and joint capsules, may lengthen or become more compliant. This increased compliance allows the joint to move more easily through its range of motion when an external force is applied, resulting in an increase in PROM.

However, the active structures, including muscles and tendons, are not affected by prolonged stretching or immobilization to the same extent as passive structures. The active structures may not become stronger or more efficient in producing force, which can limit the amount of active movement available at the joint. As a result, the AROM may not increase to the same extent as the PROM.

89
Q

Explain temperature benefits in deformation of a joint/tissues in relation to the stress-strain relationship.

A

Heating will increase elasticity of the joint or tissues allowing for load to be placed on the joint/tissues and deformation to occur.

Cooling, also known as cryotherapy, can enhance deformation of a joint or tissues by decreasing their stiffness and increasing their plasticity.

Q

Checking the fit and educating the client on a custom orthosis is the most important aspect of this topic for the course, what are you checking for with the fit, and what are you educating on?

A

When checking the fit of a custom orthosis, we as OTs are checking that the client can complete what they need and want to do while wearing the orthosis. We are also checking to see if there is any pain or discomfort. We should check skin/circulation after the client has worn the orthosis for 20-30 minutes.

A

To prevent pressure points.

Compensatory

110
Q

What are two things you can do as an OT to encourage patient adherence to orthosis use?

A

Incorporate patient’s preferences in design, and incorporate aesthetics.
- Educate family members about orthosis.
- Educate patient on benefits.
- Educate about wear, care and hygiene.
- Make sure orthosis is good fit and comfortable.
- Offer options when possible.
- Create for easy donning/doffing.
-Collaborate with patient on wearing schedule.
