DIRECTIONS:

The following questions require short answers only; you do not have to use complete sentences. All questions refer to the article “Preliminary Evidence for Effectiveness of a Stance Control Orthosis” by Amy Gross McMillan, PT, PhD, Kevin Kendrick, PhD, John W. Michael, MEd, CPO/L, FAAOP, FISPO, James Aronson, MD, Gary W. Horton, CO, FAAOP.

DISCLAIMER:

Please allow 2–4 weeks for processing.

1.

Individuals with neuromuscular and/or musculoskeletal disorders exhibiting knee instability are often prescribed    with a locking knee.

2. Using a knee-ankle-foot orthosis (KAFO) may result in:

a. a stiff leg gait pattern due to lack of knee movement

b. individuals walking a great distance before they fatigue

c. increasing an individual’s ability to perform functional tasks that require more toe clearance.

3.

True or False?

Long term use of a locked knee-ankle-foot orthosis (KAFO) may lead to pain and loss of motion due to soft tissue and joint dysfunction.

4.

A    provides the needed stability in stances while allowing the knee to move freely during stepping.

5.

True or False?

Horton’s Stance Control Orthotic Knee Joint (SCOKJ®) blocks flexion to prevent knee collapse using a one-way cam lock.

6. The three different control modes of the SCOKJ® and their meanings are:

a.           

b.           

c.           

7.

True or False?

While wearing the SCOKJ®, the improved symmetry and decreased compensatory movements increase the energy cost for walking and allow the subjects to fatigue sooner.

8.

True or False?

Based on the comments gathered in this study, it is suggested that stance control orthoses (SCOs) may increase patient acceptance compared to locked knee-ankle-foot orthoses (KAFOs).

9. The use of indirect calorimetry in future studies will:

a. more thoroughly document the difference in energy expenditure.

b. verify the greater efficiency when walking with the SCOKJ® versus the locked KAFO.

c. both a and b

10.

True or False?

The SCOKJ® appears to be an ineffective alternative to the traditional locked knee-ankle-foot orthoses (KAFO) for some patients with lower limb dysfunction.
