How to normalize gait - Dynamic AFO Foot Drop Brace after stroke

Ankle foot orthoses (AFOs) are frequently prescribed to improve gait deviation and normalize walking patterns in patients with drop foot hemiplegia disorder. In healthy individuals, the functional lower limb shortening which is hip & knee flexion and ankle dorsiflexion mainly achieve toe clearance. By the way, reduction of toe clearance of the affected foot derived from ankle joint disability(foot drop) causes the abnormal movement of knee and hip hike to compensate for the ankle movement. It is a major cause of falls in patients with foot drop disorder.

What are Dynamic AFOs?

Conventional AFOs are used to restrict ankle plantarflexion/dorsiflexion movement, thus maintaining the hemiparetic foot in a fixed position of dorsiflexion to facilitate swing. However, this ROM restriction in the ankle joint disrupts the rhythm of gait and increases energy consumption during walking. To alleviate this issue, hinge-applied AFOs were developed to allow some ankle flexibility during the loading response on the affected lower limb, thus slightly reducing the energy cost of hemiparetic gait. It is generally called Dynamic Ankle Foot Orthosis(DAFO). Dynamic Ankle Foot Orthosis(DAFO) generally refers to a custom-made Supra-Malleolar Orthosis fabricated from thin thermoplastic material. It fits the foot intimately and the flexible and thin thermoplastic use means that DAFO can provide circumferential control of the rear and forefoot to maintain a neutral alignment. In the original designs of DAFOs, a ‘neurological’ footplate was often incorporated that consisted of a pad at the peroneal & calf site with dorsiflexing the toes.

These days, the prefabricated DAFOs are common and those are usually applied with shoes to use in daily life especially in outdoor activities.

Who needs a Dynamic Ankle Foot Orthotic (DAFO)?

  • Individuals who have had foot drop after stroke or other neurological deficits as well as nerve injuries resulting in abnormal gait.
  • Those who need to regain the rhythm of gait and increase energy efficiency during walking.

Before buying an AFO, check if the orthosis...

  • is tested by experts
  • is easy to wear with shoes
  • supports the ankle and keep dorsiflexed properly
  • keeps the ankle and foot from inverting and dropping
  • allows ankle mobility for a various movement like squat and lunge
  • provides support only where it is needed, swapping unnecessary bulk for a slim fit and cosmetically-appealing look
  • promotes balance improvement through correction of limb asymmetry and hip joint compensation



Neofect STEP Dynamic AFO

Neofect STEP is designed to support the ankle and keep the foot dorsiflexed by the Neofect’s expert physical therapist. The main purpose of AFO is to keep the ankle and foot from inverting and dropping at the initial contact and toe-off phase. Also, neutral foot positioning assist ensures a secure heel strike, while ankle joint stabilization corrects varus/valgus positioning in mid-stance. Dynamic dorsiflexion through the elastomer ankle joint ensures toe clearance during the swing phase. This can be caused by nerve injury, muscle or nerve disorders, brain or spinal cord disorders. With its flexible/supportive hinge component, an AFO helps individuals walk more naturally while lifting the foot and keeping the ankle in alignment.

Foot drop causes the toes to drag on the ground, creating the need for gait changes to compensate to clear the foot. It’s forcefully making you use those muscles that have atrophy, so you can see a difference when not wearing it. Also, it provides enough range of motion to still be able to squat, lunge and perform a higher level of balance. And the foot-plate supports approximately of foot length. It retains flexibility and prevents paresthesia in the toes.

Neofect STEP provides a strong, lightweight solution to support people with a range of walking disorders caused by a variety of neurological and musculoskeletal disorders.
