Clinical Application of the PreStride™
1. The PreStride immediate fit stance control orthosis is suitable
Transition assessment from a static KAFO to a custom SCO.
Step training for chronic patients.
Rehab locomotor training for acute patients.
All of the above.
None of the above.
2. The weight limit of the PreStride is?
330 pounds.
220 pounds.
230 pounds.
320 pounds.
3. The GX pneumatic spring biomimics the function of the?
Hip flexor muscle.
Hip extensor muscle.
Quadriceps muscle.
Gluteus maximums muscle.
4. The pressurization of the GX assist pneumatic spring on the
PreStride is?
5. The FullStride stance control knee joint unlocks by?
Forward progression of the tibia.
Dorsiflexion of the ankle joint.
Plantarflexion of the ankle joint.
Distal movement of the lever lock.
6. The preferred internal component set up of the double action ankle joint in the
PreStride is to have?
An anterior pin and posterior spring.
Posterior pin and anterior spring.
Double pin.
Double spring.
7. Accommodating the heel rise of the patient’s shoe with the adjustment of the
PreStride will?
Provide a cosmetic combination of shoe and orthosis.
Match the step length lever lock release point in stance phase.
Provide toe clearance in swing phase.
Prevent limb circumduction of in swing phase.
8. A stance control orthosis offers gait normalization via?
Dorsiflexion of the foot in stance phase.
Biomimicry of the anterior tibialis at initial contact.
Pelvic rotation in swing phase.
Limb shortening through the combination of hip and knee flexion.
9. The first step in setting up the PreStride for a patient gait trial is to?
Set the dorsiflexion stop setting.
Set the cable length.
Set the knee height.
Set the step length.
10. The posterior spring in the double action ankle joint biomimics
Anterior tibialis muscle.
Extensor hallucis brevis.
11. The second step in setting up the PreStride for gait training is to?
Adjust the thigh band for angulation and depth.
Set the cable length for step length.
Adjust the posterior spring of the double action ankle joint.
Set the calf band for midline knee joint placement.
12. The first patient exercise in pre-gait training is?
To demonstrate transverse plane pelvic rotation.
Weight shifting from limb to limb.
Demonstrate heel strike to foot flat range of motion.
To demonstrate circumduction of the hip in swing phase.
13. Adjustment of the posterior pin of the double action ankle joint
Control heel strike to foot flat ankle acceleration.
Quiet the return of the locking lever at terminal swing full extension.
Provide dorsiflexion clearance of the toe during swing phase.
None of the above.
14. The bolster on the proximal strap of the thigh cuff controls?
Progression of the femur in swing phase.
Migration of the orthosis during swing phase.
Circumferential pressure on the thigh in the presence of an atrophic limb.
Inhibits transverse plane rotation of the pelvis in stance phase.
15. In setting the stance control cable length the PreStride should be held in a vertical
position in order?
To allow reading of the index numbers on the distal upright.
To release pressure on the ankle joint pins.
To allow the correct distance from the lever lock to the cable attachment on the stirrup.
To ease the spring tension on the posterior spring of the double action ankle joint.
