Latest Research

Constant research in the field of bio engineering has given improved models of artificial limbs that very nearly replicate the functions of real, biological limbs. Phenomenal advances have been made in measurement techniques, materials science and manufacturing methods to render more realistic prosthetic limbs. Heavy, natural materials like wood, metal, alloy and leather are replaced by lighter, synthetic materials such as polyester resins, epoxy, high density poly ethylene (HDPE), high density polypropylene (HDPP) and other carbon fiber composites that render the artificial limbs lighter and more durable.

Two computerized control systems—myoelectric artificial limbs for upper limb amputees and cadence knee mechanism used in lower artificial limbs have afforded greater maneuverability for those who use artificial limbs. In the myoelectric prosthesis, when the amputee thinks and wants to open or close the fingers in his artificial hand, electrical signals produced at a neuro-muscular junction of the forearm are picked up by sensors inside the socket and activate a motor fixed in the wrist unit and make it move the fingers. It is also called the bionic prosthesis since it involves the amputee’s thought process.

Artificial/Prosthetic Limbs

The cadence control prosthesis involves a special knee unit that can be preset at different speeds and controlled through microchips. It vastly improves the gait of the amputee because the sensors in the artificial limb can judge the gait and speed of the normal limb and adjust the speed of the prosthetic knee accordingly.

Prosthetic experts are confident of huge improvements in the field to enable the user move more naturally with artificial limbs. Modern research is moving towards the ideal artificial limb that is lightweight, durable, easily adjustable, maintenance-free and looks almost real.

One latest development is a software that lays a grid on a CAT scan of the stump which gauges the exact pressure the soft tissue can hold with minimum pain. The prosthetist can design a socket that reduces the amount of soft tissue displaced by just looking at this computer model.

Research is also on to devise a pressure sensitive foot that could help amputees walk more naturally by enabling them feel the ground even with their artificial feet. Another new development in artificial legs is a built in computer in an above-knee unit that can be programmed to suit the person’s gait.

University of Michigan researchers from the departments of Biomedical and Mechanical Engineering have developed an energy-saving artificial foot which saves energy wasted in between steps and facilitates walking for amputees by recycling the saved energy.

Why can't these be purchased, affordably, in the USA, to help provide revenue to provide free limbs to those in need? My Mother has a clunky prosthetic below the knee. This would seam to be much better... And EXTREMELY More Affordable.

My right hand limb has disabled and i need it to be replaced by artificial limb. Think you might be of some help to me.

Hi Mayur, It's really sad that you have to go through the pain of disabled limb. It's a good idea to go for artificial limb so that you don't feel helpless. Please let me know your city of residence so that I can suggest a few options for you. God Bless!

In 2005, my mother fractured her right leg from above the ankle. Owing to medical negligence the broken bone could not be fixed and the foot from the lower shin is hanging which is required to be amputated. She is 92. She need a prosthetic leg. Please advice.

My uncle just lost his right hand from below the wrist. We are thinking of a prosthetic hand that has sensors and can perform atleast the basic tasks like signatures. Can anyone help me with this regard.
