Lower limb injuries that impact a patient’s ability to walk can lead to pain in the knees, back, and hips. This project investigated the functionality of an ankle-foot orthosis known as the Intrepid Dynamic Exoskeletal Orthosis (IDEO) that attempts to salvage injured lower limbs using principles of biomechanics. The team studied the function of the IDEO to model its ability to transfer energy to affected limbs and restore normal gait function. The IDEO stores and returns energy to the bodies external to the device while the patient walks using favorable material properties to replace the function of injured parts of the body. It provides substantial support during the stance phase of the gait cycle, and further development of accurate models will assist in evolution of similar devices.
