Both rehabilitation techniques and prostheticdevices have improved because of the wars in Iraq and Afghanistan, said Steve Gard, the executive director of Northwestern University Prosthetics-Orthotics Center in Chicago.
Several retinal prostheticdevices have been under development, but their optical resolution has been poor and they present challenges in achieving long-term compatibility with host tissue, Mr. Isacoff says.
These are basic movements many of us take for granted: a tri-pod grip to pick up a pen, or hand-shake grip for business meetings, said Miguelez, who has fitted hundreds of amputees with prostheticdevices.
