About TRS


bob_radocyTRS Inc. was formed in 1979, by upper limb amputee Bob Radocy, who was frustrated by the limited performance of commercially available prosthetics devices. He lost his left hand about four inches below the elbow in an auto accident in 1971. Bob experimented with all types of prosthetic devices. In 1977, while in graduate school, he applied his engineering and biological sciences education and design experience to create a high performance, prehensor which allowed him to be competitive with two handed peers in any activity he chose. Thus in 1980, the GRIP prehensile hand was first manufactured.

Since then, TRS has grown to become the leading innovator of body-powered prosthetic devices in the world. TRS remains specialized. We design and build only high quality technology for persons missing a hand(s). Please use TRS as your personal information resource in upper limb prosthetic technology. We are here to help you! TRS Products are available through all certified prosthetic and orthotic facilities in the USA and via specific prosthetic resources worldwide. Please contact TRS directly if you would like an informative brochure or more specific information and please help us by letting us know that you heard about us on the WEB, via the O&P Online Community. Thank you!
