For the technical project, a bidirectional assisted walking system was developed. Cerebral palsy is the most common cause of physical disability in children affecting 2 to 3/1000 children worldwide. 31% of children with CP in the US use special equipment of some kind. When it comes to mobility, many individuals with CP rely on walkers or wheelchairs. As part of his PhD project, Evan Dooley is designing a power walker to allow children with CP to spend a longer amount of time per day on their feet, by decreasing the amount of effort it takes for people with CP to get around. In order to properly decrease the amount of effort that individual’s with CP exert while walking, there is a need to know how much pulling force the walker will need to apply based on the person’s body weight. Typically, these types of measurements are done via treadmill walking, however treadmill walking elicits different gait patterns than normal, or overground walking. Such as differences in stride length and phase durations. Our goal was to create an overground walking system that will allow for continuous data collection. In order to do this a bidirectional system was constructed that has a pulling force on each end applied by a weighted pulley system and a belt that allows for turning 180 degrees. The system is also compatible with a VO2 measurement system so the metabolic cost of different body weight percentages of applied forces could be examined.
The topic for the STS Research Paper is the perception of disability within an academic setting and what physical factors may contribute to that perception. Individuals with disabilities are often considered as “other” when it comes to architectural design. The paper looks to determine whether that sense of “otherness” translates from the physical built environment and into feelings of students with disabilities and views held by able-bodied students along with social and interpersonal relationships between students. The question that the paper focuses on is: how does the physical built environment of a university campus contribute to hierarchical power differentials between able-bodied and students with disabilities? To analyze this question the STS framework of political artifacts developed by Langdon Winner is used as it suggests that technologies play an integral role in cultural and the establishment of power hierarchies. The discussion centers around the University of Virginia (UVA) and uses discourse and documentary research. The physical built environment of UVA at one point contributed to a power differential between able-bodied and students with disabilities. However, over time with renovations and improvement projects, the Grounds of UVA will allow for a more inclusive space; the case of the Lawn was specifically looked at to highlight change over time. The research being done seeks to highlight how environments and the technology associated contribute to the view people have of others. It may be unintentional, however the space that has been made or the technology being used holds power to create differences between people that must be acknowledged to create a more equitable society.
