      question 90
      A patient presents to your clinic with a diagnosis of foot drop due to a common peroneal nerve injury. Which orthosis would be best for this patient?

      It says the correction answer is posterior leaf AFO.

      However, common peroneal nerve injury also causes weakness on fibilaris longus and brevis which is causing eversion weakness and medial-lateral instability. Posterior leaf AFO doesn’t not provide any medial-lateral instability.

      Hi Stephanie,

      Thank you for this question! We concluded that a posterior leaf spring AFO would be appropriate by following the Rancho ROADMAP that is reviewed in the course. However, clinical judgement definitely plays a role in determining the best orthosis for individual patients. If weakness of the ankle evertors is interfering with foot placement and stability during gait, a rigid AFO may be preferable to a posterior leaf spring AFO.
