Objective: The main objective of this study was to determine functional and neuromuscular outcomes of stroke patients using their non-preferred hand with and without a 3D printed passive exoskeleton compared to controls using their non-preferred hand with and without the passive exoskeleton. Methods: Adults at least six months post stroke (Stroke, n = 5) and age- and sex- matched healthy controls (Control, n = 5) performed nine trials of a gross motor task while having their brain activity measured. The Fugl-Meyer and “Box and Block” test was used to measure the gross dexterity of the subjects with and without the …

The ankle joint is one of the most important joints during walking. If the muscles surrounding the ankle are weak, there are reductions in the ability to generate appropriate torques and powers at the ankle. This leads to slower self-selected walking speeds, which correlate with poor physical functioning, more disabilities, increased hospitalization visits and costs, and even mortality. Because of this, many orthotic and exoskeletal devices have been created to restore proper ankle function by promoting ankle plantar flexion. Utilizing 3D printing and an extension spring, we created an easily accessible, reproducible, and modifiable exoskeleton that has the potential to …

Falls pose a significant health hazard, resulting in devastating injuries like broken wrists, fractured hips, and traumatic brain injuries that exceed $50 billion in U.S. medical costs. To address these risks, biomechanists have subjected individuals to simulated slips in order to study the factors that lead to falls. These studies have focused on slips that happen immediately after heel-strike and are unnaturally restricted by the methods used to cause the slip. Therefore, the effects of unconstrained slips that occur throughout stance phase are unknown. To address this knowledge gap, we examined the relationship between the timing of slip onset and …
