When customizing an ankle foot orthosis for a patient,the therapist and orthotisttypically work together to determine the best position for the foot and ankle. If an individual status post stroke is unable to tolerate the abrupt heelstrike-to-foot flat motion that is presented in thepreceding scenario, which of the following is the best accommodation?

Lock the ankle in 5 degrees of plantarflexion instead of neutral. Doing so will leave less distance for the foot to travel during heel strike to foot flat, but still allows enough toe clearance during swing phase because the toe will still be held up.

Taking into consideration, the increased knee flexion during foot flat in the scenario, would this form of orthosis be appropriate for an individual with 0/5 strength in the ipsilateral quadriceps?

No, this orthosis will affect the ankle and will put the knee in the flexed weight-bearing position, which will require increased quadriceps strength to maintain stance.

Although the ankle foot orthosis (AFO) is designed to aid in swing phase of gait, what biomechanical changes are expected during the heel strike to foot flat stages of the stance phase?

Owing to lack of plantarflexionrange of motion (ROM),heel strike will abruptly proceed to foot flat; the knee will require more eccentric extensor strength and, ultimately, increased knee flexion at foot flat.

Tension on the thoracodorsal fascia via abdominal muscle contraction will cause it to decrease spinal stiffness.

For this individual to position in better alignment with the "plumb line" and stand without upper extremity (UE) support, what must he do? On which anatomical structures must he depend?

The individual must shift his UE weight behind the plumb line, allowing his hips to rest in extension on the "Y-ligament."
