Team is tasked with the creation of a Hip Flexion Assist Device (HFAD), due to the current lack of similar devices on the market. The purpose of this device is to effectively supplement hip flexor activity during the swing phase of the gait cycle. The core demographics targeted for this device are people affected by MS, TBI, and stroke. The HFAD includes mechanisms that allow it to be adjustable and effective for a range of body types and sizes. It utilizes Thera-Band as the primary mechanism of assistance due to its elastic material properties and availability in therapy clinics. The primary goal is to assist with returning a symmetrical gait cycle to patients and promote motor learning.
