Patent Pending

The Natural Dexterous Hand (Patent Pending) is the first low cost body powered prosthetic hand that looks and moves like a normal hand, providing the user the capability to pick up a glass or a soda can and drink without worrying about loosing control.

The Natural dexterous Hand is light weight and completely interchangeable with hook devices using the standard harness cable and threaded attachments.

The Natural Dexterous Hand is unique in the industry as all five fingers flex at 14 individual joints providing "just like human hand motion" without the cost associated with electronic mechanisms. It is so versatile the user has the capability of catching a ball in flight. See film clips below.

Easy to manufacture and assemble with only 10 individual plastic molded parts and one size rivet and screw used throughout.

It has been tested to over 250,000 operations and has proven reliability.

What makes the Natural Dexterous Hand so superior to any other body powered device is its' ability to flex each finger and hold odd shaped objects such as an aluminum soda can with less cable travel and force than a hook mechanism.

Compared to other body powered prosthetic devices on the market only the Natural Dexterous Hand has all of the features most desired by users. (see graph)
