The exposition talks about prosthetics and orthotics that are terms used in medicine, prosthetic is an artificial deviceextension that replaces a missing body part.

It is part of the science of using mechanical devices with human muscle, skeleton, and nervous systems to assist motorcontrol lost by trauma, disease, or defect. Prostheses are typically used to replace parts lost by injury or for supplement defective body parts.
Prosthetics arespecifically not orthotics, although given certain circunstances a prosthetic might end up performing some or all of the same functionary benefits as anorthotic.
By the other way orthosis is an orthopedic device which support or correct the function of a limb or the torso.
For the future, they are making clinicaltrials that begins once 5 prototypes of different sizes are constructed, they will be evaluated in a home setting, then in the lab, to measure performance forspecific tasks. A comparison will be made with the existing orthotics.
They are made from multiple types of materials including wood, plastic, elastic, metal, or acombination of other similar materials. Some design can be bought at a local retailer while others are more specific and require a prescription from anspecialized physician who will fit the brace according to the patient's need.
Prostheses typically cost between $6,000 and $35,000 dollars.
Low cost prostheses oftenprovide only basic structural support with limited function. This function is often achieved with crude, non-articulating, unstable, or manually locking knee joints.
