Targeted reinnervation has an efferent and an afferent component. Targeted muscle reinnervation is a method by which a spare muscle (the target muscle) of an amputated patient is denervated (its original nerves cut and/or de-activated), then reinnervated with residual nerves of the amputated limb.

A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those with partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s.
Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis, i.e. fusion of the bones.
In myoelectrics, weak electrical voltages control the prosthesis. [14] [15] Another development was a fitting solution for modular leg prostheses. The pyramid adapter, patented in 1969, connects the prosthetic foot, knee joint and stem and allows static corrections as well as the exchange of the modules.
For example, four different steps must occur to lift the foot to walk. First, impulses from the brain's motor center are sent to the foot and leg muscles. Next, the nerve cells in the feet send information, providing feedback to the brain, enabling it to adjust the muscle groups or amount of force required to walk
The Soleus foot. Bilateral lower-limb amputee Reggie Showers rock climbing on Trustep feet. College Park Industries is a prosthetics manufacturer headquartered in Warren, Michigan. The company was founded in 1988 after a local machinist set out to create the world's most anatomically correct prosthetic foot.
