Prosthetic limbs have a long history dating back to 950 B.C. where a Egyptian noblewoman had a prosthetic toe of leather and wood. Over the years there have been several advancement in technology, making these artificial limbs a lot more comfortable for the wearers.In the next few sections we will look at the how things have changed for such prosthetic limbs.A Look at Changes in Prosthetic Limbs Use of Heavy Metals and WoodIf we go back in time to about 300 B.C. then we find that artificial leg was used in Italy made out of iron and bronze having a wooden core which was used by a person with below knee amputation.In the following years little advancement occurred in such prosthetic limbs and peg legs as well as hand hooks become common. Oftentimes such prosthetic use served the purpose of hiding injuries or deformities which occurred during battles.Advancement in TechnologyIn 1508 advancements in technology were reported where iron hands were being used which has springs and releases to help with movements of the hand.In France advancement in technology was development of above knee prosthetic devices such as the kneeling peg foot and leg prosthesis which had adjustable harness, fixed position and knee lock control.This era also saw the use of paper, leather and glue instead of iron for manufacture of these artificial limbs.Developments from 17th to 19th CenturyRight at the onset of 17th century non locking below knee prosthesis was developed followed by designing of prosthesis created using wooden socket and shank along with articulated foot in 18th century.By 1863 further advancements occurred with prosthesis being manufactured having polycentric knee, suction socket as well as articulated foot. This era also witnessed the use of aluminum to replace steel for making prosthesis lighter as well as more functional.The Present TimesNowadays we have 3d systems prosthetics along with prosthesis which is controlled by computer chips and microprocessors. Additionally, these have more natural look and feel due to use of silicone with function which easily mimic the movements of natural limbs.Technology has transcended to help the movement away from mechanical prosthetic limbs to devices which have bio-mechanical properties and can be controlled by mind. The use of electronic sensors makes sure that the devices have advanced functionality as well as dexterity which no one dreamed of earlier.Robotics, 3-D printing, brain-computer devices, 3d systems prosthetics and devices controlled by microprocessors are leading the way to prosthetic limbs which are able to provide high performance, are light weight and allow amputees to move or use their hands and legs in a much more natural way than it was possible before.
