Question 1

When fitting a thoracolumbosacral orthosis (TLSO), the superior trim line anteriorly should be positioned:

Accepted Answer

Two finger-widths below the sternal notch

Answer

Positioning the anterior superior trim line two finger-widths below the sternal notch allows comfortable breathing and prevents impingement during sitting.

Question 2

A patient with a cervical orthosis reports persistent occipital pressure sores. The best corrective action is to:

Accepted Answer

Reduce the height of the posterior occipital pad

Answer

Reducing occipital pad height relieves direct contact pressure while maintaining cervical support.

Question 3

In fitting a scoliosis orthosis (TLSO), the apex pad is placed:

Accepted Answer

On the convex side of the curve at the apex level

Answer

The apex pad applies a corrective force from the convex side to push the spine toward correction.

Question 4

When evaluating AFO fit during gait, heel rise during terminal stance indicates:

Accepted Answer

The plantar flexion stop is too soft or absent

Answer

Premature or excessive heel rise occurs when the plantar flexion stop does not adequately resist push-off forces.

Question 5

A key step when checking the fit of a custom foot orthosis (CFO) is to:

Accepted Answer

Assess the patient standing with the orthosis on a flat surface before in-shoe check

Answer

Checking fit on a flat surface first allows visual inspection of contact, alignment, and edge clearance before the orthosis is enclosed in the shoe.
