Leading Innovator of body-powered prosthetics.
TRS 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 and continues to design and build only high quality technology for persons missing a hand(s).

Greetings and from Nova Scotia, Canada. I’ve used a prosthetic for the last ten years, after losing my right arm in a workplace accident. I got back into biking a few years ago, and was using a basic attachment with a sort of ratchet strap to hook onto the handlebar. My prosthetist got me one of your mountain master hands, and what a difference!! It’s so much easier to turn and to control the bike. It’s nice to have the confidence to actually go on more off road and rough trails, it handles so well! Just wanted to reach out to say thanks so much, the work you do is literally life changing! I’ll be on the bike all summer, so hopefully be able to send more pics or a video of it in action.
I just wanted to thank you all for helping me get set up with the wrist and the Multi-D. I'm working on my private pilot's certificate and the combination works perfectly! The wrist disconnects quickly when the instructor wants to take control to demonstrate and snaps back on easily when I'm back in command. The Multi-D holds on tightly and rotates just right for full yoke movement.
My name is Luisa Rocha and i am a product and industrial designer that is interested in designing prosthetics for leg amputees, i just came across your work in TRS and i have to say that i am thrilled to see such a big variety of designs that i didn’t know could be done in a really easy and simple design, my favourites are the kahuna, hélix and mill’s rebound, and i really hope i can help as much people as you have. As i said i am interested in designing and maybe producing a new design for leg amputees, to be specific, skaters; right now i have this crazy idea in my head that i don’t even know if it is possible to make or even if it could actually help, but even so, i am trying. Sorry if this e-mail doesn’t say anything specific, i just wanted to let you know that you inspired me and that seeing your work has encouraged me to try to make my design a reality, if i ever succeed, i Will let you know. Thank you!
Hi Bob, I just wanted to send you a note to say thank you for all that you and your team do. My daughter Grace has used your Pediatric Pro Cuff and Criterium Wedge to ride her dirtbike for a little over a year. Her passion for riding easily exceeds that of her brother and sister. We have to force her to take breaks to rest otherwise she will keep riding until the bike runs out of gas. I'm so thankful we have been able to find your products through Blue Sky USA Prosthetics here in Austin, TX. Attached are a couple of pics of her riding and jumping. Thank you again for everything you do!
Hey Bob, Just wanted to thank you for making the guitar prosthetic for people like me. It has given me back a piece of my life that I thought I had lost. Thanks and keep up the good work!
I’m really looking forward to more riding with the Pivot, already in the first 2 minutes I was impressed. I have never experienced such freedom of motion, anatomical balance and security on the handlebars as I did with the Pivot. Great product!
I wanted to give some feedback on my latest ride with the MTN master. I rode downhill at Winter Park. Overall, it was so awesome to be able to do this and I never would have imagined doing this before. I will definitely be doing some more downhill in the future.
I have recently added a TRS prehensor and TRS kayak attachment to my rotation of prosthetics, with a TRS golf attachment on the way. Thank you so much for the attachments you've created/made. I truly believe I can get back my quality of life since I found you on the web. Keep up the great work while I adapt my life with your products.
Thank you very much for the Hoopster hand. It is by far my favorite hand yet. My shot is 3x's better now! Thank you so much for providing great products and bettering amputee's quality of life!
Thank you so much for the prosthetic attachments! They help me so much!
Thanks for such an unbelievable product! Using your Grip 3 Hand and Harness, I was able to write my name again. I can't begin to tell you how excited I am.
Thanks so much for allowing me to borrow some items to show my students who are majoring in Outdoor Education. They very much appreciated being able to see, touch and examine these items and how they make these activities possible.
Thanks again. I couldn't enjoy riding my motorcycle so much without your Grip!
I would like to thank Bob Radocy for his generosity on donating the TRS terminal device, this was provided to beneficiary Maria Rodas completely at no charge to her.
