Please allow two to four weeks for processing.

Quiz–Ankle-Foot Orthosis Selection to Facilitate Gait Recovery in Adults After Stroke: A Case Series, Karen J. McCain, PT, DPT, NCS, Patricia S. Smith, PT, PhD, NCS, Ross Querry, PT, PhD

  1. [Select the correct response.] According to the article, ___________________ contributes to the asymmetry by interfering with foot clearance, knee control, and propulsion.
    1. atrophy of the mid-calf muscle
    2. weakness of the lower leg muscles
    3. underdeveloped quadriceps and hamstrings
  2. (True or False) ______________ Ankle-foot orthoses (AFOs) are rarely prescribed to improve gait after stroke because they have not been proven to be effective.
  3. [Select the correct response.] AFOs may be used to do all of the following except:
    1. decrease energy expenditure
    2. improve foot position
    3. decrease walking speed
    4. improve mediolateral ankle stability
  4. [Select the correct response.] The custom-fabricated thermoplastic configuration used consisted of a _________ in each of the posterior channels and a _________ in each of the anterior compartments.
    1. stiff spring…pin
    2. joint fastener…plug
    3. flexible foam cushion…strap
  5. (True or False) _____________ The AFOs were all initially set to allow 8–10 degrees of dorsiflexion and no more than 3–5 degrees of plantarflexion.
  6. [Select the correct response.] Concerning gait endurance and velocity, the 6-Minute Walk Test (6MWT) was used, and distance was recorded with a _____________.
    1. stop watch
    2. measuring wheel
    3. tape measure
  7. (True or False) ______________ Symmetry was calculated as the ratio of paretic to non-paretic limb for step length, swing time and stance time as well.
  8. (True or False) __________________ Numerous studies have attempted to consider the long-term implications of orthosis use after stroke.
  9. (True or False) _____________ Evidence suggests that prolonged activity of the quadriceps and hamstrings during stance on the paretic and non-paretic limb is common with and without AFOs.
  10. [Select the correct response.] The ability of the AFO to provide the opportunity for ____________ becomes key.
    1. calf strengthening
    2. ankle strengthening
    3. hamstring and quadriceps development
  11. [Select the correct response.] According to the article, recovery of calf strength is typically limited to about _____________ after stroke.
    1. 17%
    2. 24%
    3. 37%
    4. 42%
  12. (True or False) ___________ Most persons regain the ability to walk within the first six to eight (6–8) weeks after stroke.
