Falls are known to be a common occurrence and a costly one as well, as they are the second leading cause of unintentional deaths and millions of other injuries worldwide. Falls often occur due to an increase in trunk flexion angle, so this experiment aims to reduce the trunk flexion received while stepping over an obstacle. To achieve this a soft actuator was attached to the trunk and pressure was sent as subjects walked and stepped over an obstacle presented on a treadmill. The pressure is meant to stiffen the back which should in theory reduce the trunk flexion angle and lower the chances of falling. In this experiment, two groups were tested: three participants from a control group (healthy young adults) and three participants from an experimental group (healthy elderly adults). Since elderly adults have the highest fall risk due to overall lack of stability, they are the experimental group and the focus for this experiment. The results from the study showed that elderly adults had a beneficial effect with the soft actuator as there was a noticeable difference in trunk flexion when the device was attached. The experiment also supported prior research that stated that trunk flexion was greater in elderly adults than younger adults. Despite the positive results, further studies should be done to prove that the soft devices influence lowering trunk flexion angle as well as to see if the device has any noticeable effect on younger adults.
The original contribution of this research is to highlight how imagination of a posthuman world has made it possible for African American writers to envision how racial power can be re-configured and re-negotiated. Focusing on shifting racial dynamics caught up in the swirl of technological changes, this research illuminates a complex process of literary production in which black culture and identity have been continuously re-interpreted.
In the post-war and post-Civil Rights Movement eras African American writers began reflecting on shifting racial dynamics in light of technological changes. This shift in which black experience became mechanized and digitized explains how technology became a source of new African American fiction. The relationships between humans and their external conditions appear in such futuristic themes as trans-human anamorphosis, cyberspace, and digital souls. These thematic devices, which explore humanity outside its phenotypic boundaries, provide African American writers with tools to demystify deterministic views of race. Afrofuturism has responded to the conceptual transformation of humanity with a race-specific scope, locating the presence of black culture in a high-tech world.
Techno-scientific progress has provided important resources in contemporary theory, yet these theoretical foci too seldom have been drawn into critical race discourses. This discrepancy is due to techno-scientific progress having served as a tool for the legitimation of scientific racism under global capitalism for centuries. Responding to this critical lacuna, the dissertation highlights an under-explored field in which African American literature responds to techno-culture’s involvement in contemporary discussions of race. Rather than repeat nominal assumptions of Eurocentric modernity and its racist hegemony, this dissertation theorizes how modern techno-culture’s outcomes—such as information science, genetic engineering, and computer science—shape minority lives, and how minority groups appropriate these outcomes to enact their own liberation.
