Abstract
The inventive subject matter provides apparatus, systems and methods in which an ankle foot orthosis (AFO) utilizes a rotary jaw coupling that prevents excessive plantarflexion and dorsiflexion of the foot, while still allowing such movements with little or no counterforce over a limited range. The jaw coupling comprises at least a first digit which is freely or almost freely rotatable between first and second stops in the range of 30° to 60° of arc, and more preferably between 30° to 40° of arc. Extreme motion of the digit(s) is limited by one or more stops. Different ranges of motion can be provided by replaceable spiders. Resilient materials can be used to provide desired characteristics of resiliency, compressibility, damping, and/or amounts of play.
