Influence of a Custom-made Dynamic Ankle-Foot Orthosis with a Reciprocant Ankle Joint System called Neuroswing on Walking Spatio-Temporal Parameters in Patients affected by a Neurological Gait Schema: A Comparative Investigational Study

Orthoses need to support physiotherapy as well as surgical treatment. Related to patient’s pathological gait, physician’s requirements and the rehabilitative goals, orthotists must produce an orthoses that using an adjustable ankle joint system with preloaded disc springs can store the energy brought in by the body weight and produce a tuning effect on patient’s gait and sense of balance. Many studies established the functional value of common and well-known ankle foot orthoses (AFOs) by developing pathological gait. Solid AFOs (SAFOs) do not allow any ankle movements and are used for patients with spasticity. The so-called Floor Reaction AFO (FRAFO) is a ventral shell orthoses that blocks any ankle joint movement, enables the knee extension in terminal stance, but is controindicated in patients with an hyperextended knee. HAFO or classical hinged AFO are designed with elastomer spring joints without any spring effect or any dorsal stop that blocks any plantar flexion and enables a dorsiflexion with defined pivot point in the anatomical ankle joint. PLS-AFOs or posterior leaf spring AFOs, have commonly a high carbon spring effect but do neither have a pivot point, a defined or adjustable range of movement nor an adjustable alignment.
