Affordable Prosthetics for Everyone

Affordable prosthesis for everyone

simplelimb-35 (Custom).jpg

The Simple Limb Initiative is an ongoing research project focused on helping amputees around the world gain access to affordable prostheses for lower limbs.

Most prostheses are expensive and for people who live in rural communities or are survivors of war, this is unaffordable. They end up making their own prostheses which can cause long term alignment problems in their body. They also can be marginalized by their family and society and drop out of school, their job, or contributing to the family. This results in long term health and well-being problems.


The Simple Limb Initiative was developed to provide an open source platform for participating in the ongoing research and development of low cost prostheses prototypes.

Prosthetists, doctors, craftspeople, and amputees around the world are encouraged to access, learn, download, build, and test any of the prototypes shown here on this site. Any feedback based on these experiences and developments will be rolled back into the ongoing R&D so that others may benefit.
