Dynamic orthotic design for a four degree burned upper limb

Scars contracture, in four degree burns, reduces articulation mobility and it needs a dynamic orthotics intervention. The better ones are those that allow small steps of angle advance, up to 2°. The focus of this work is to show a new design capable to make an angle variation under 2° within 24 hours and a model to realize a treatment scheme. The device was built by the orthotics procedure using goniometry and trigonometric formulas. The idea was to use screw threaded systems designed for an angular extension under 2°. The easy way to build the modularity and the low production cost for this device recommends it for the use in clinical practice.
