All TRS products, including videos, parts and accessories are available from professional, certified prosthetic facilities. Additionally certain medical clinics and rehabilitation hospitals have prosthetic departments through which TRS technology is available.

Persons interested in comprehensive prosthetic service and care should always utilize the services of a certified prosthetist. Prosthetic facilities handle the coordination of your personal health insurance coverage, conduct billing for services and facilitate “Clinical Trials and Field Evaluations” of TRS products. Importantly these facilities and professionals ensure that your prosthetic technology and hardware is totally compatible, properly installed and aligned for optimal operation. TRS can help with referrals to certified prosthetic facilities that are familiar with TRS technology, in your area.
