J. Martin Carlson’s Technical Articles
In 1990, J. Martin “Marty” Carlson founded Tamarack Habilitation Technologies, Inc. to provide custom seating support orthoses. Visit Marty Carlson’s website to browse his published articles related to flexure joint technology, friction management, sitting support orthosis design, spinal orthotic design biomechanics, lower limb orthotic design and biomechanics, mobility and personal interviews featured in industry publications.
Veterinary Orthotics & Prosthetics
After recognizing that our Tamarack Flexure Joints were being used in the fabrication of animal orthotic & prosthetic devices, we developed launched the Veterinary Orthotics & Prosthetics Directory as a resource for pet owners and veterinary medicine staff to learn more about, and connect with, veterinary orthotic & prosthetic facilities, worldwide.
