COF Patient Assessment & Measurement 2

Question 1

When assessing a patient for a custom ankle-foot orthosis, which measurement is taken from the fibular head to the floor?

Accepted Answer

AFO height

Answer

The AFO height is measured from the fibular head to the floor to determine the proximal trim line of the orthosis.

Question 2

A patient presents with excessive subtalar pronation during gait. Which assessment finding would BEST confirm this observation?

Accepted Answer

Calcaneal eversion exceeding 5 degrees during stance

Answer

Calcaneal eversion exceeding 5 degrees during stance phase is a primary clinical indicator of excessive subtalar pronation.

Question 3

Which tool is used to measure the angle of forefoot varus or valgus during a static foot assessment?

Accepted Answer

Goniometer

Answer

A goniometer is used to measure the forefoot-to-rearfoot relationship, quantifying varus or valgus deformity in degrees.

Question 4

During patient history intake for orthotic fitting, which question is MOST relevant to orthosis material selection?

Accepted Answer

Do you have any latex or nickel allergies?

Answer

Latex or nickel allergies directly impact material selection since many orthoses use thermoplastics with nickel hardware or foam liners containing latex.

Question 5

When measuring for a wrist-hand orthosis, which landmark defines the distal palmar crease boundary?

Accepted Answer

The metacarpophalangeal joints

Answer

The distal palmar crease corresponds to the metacarpophalangeal (MCP) joints, and orthotic trim lines typically end just proximal to this crease to allow finger flexion.
