| Abstract: | Ankle joint offloading ankle orthoses are great assistive tools for people rehabilitating from isolated osteochondral lesions in the talus. It enables patients to control weight-bearing during the rehabilitation period after surgery. Current methods for achieving partial weight-bearing, e.g. crutches, splints, or braces, can interfere with daily activities for active and young individuals. In addition, the accurate assessment of the offloading of the ankle is challenging. Two prototypes have already been developed, but these do not meet the requirements yet. In this research, the second prototype will be redesigned and evaluated to ensure compatibility of the ankle joint offloading ankle orthosis for usability with healthy individuals. The usability, functionality, and adjustability of the orthosis were refined. In addition, the mechanical performance of the redesigned prototype was assessed during functional tests and the comfortability of the orthosis was evaluated during walking tests with healthy individuals. After some adjustments during the functional tests, the strength of the device was proven, ensuring compatibility for usability testing with healthy individuals. Additional adjustments were made during the subject validation tests, and the final subject test succeeded. Therefore, the device proved to be a promising design step in the direction of a solution in the development of an ankle joint offloading ankle orthosis. |
