Description
Hope’s Crossing is a non-profit organization that serves formerly incarcerated and unsheltered women in the greater Phoenix community. Their mission is to help mitigate the disparity between men's and women's post-correctional care, recognizing that women bring unique issues that often go unaddressed. Their services include vocational training, group discussion and connection, volunteering opportunities, and clothing donations. While Hope’s Crossing was founded shortly before the COVID-19 pandemic, its service capacity and staff bandwidth have been hindered by its momentary closure. However, the positive morale of its CEO and founder, Laura Bulluck, employees, and Arizona State University (ASU) interns have propelled the organization in a new direction. The purpose of this creative project is to raise awareness of this new direction, thus helping this community resource to be more accessible to and utilized by those who need it most. My other goal is to help garner stakeholder attention, participation, and funding for long-term organizational expansion.

Description
Over the past decade, fall related injuries and death among individuals 65 and older due to osteosarcopenia have increased significantly. To reduce the risk of recurrent falls among the elderly caused by osteosarcopenia, a soft-body pneumatically stabilizing device is designed. A few different actuation methods are considered, both rigid and soft body actuators, before deciding the best fit for the design goals of the wearable assistive device. Much of the design is developed through numerically modeling and analyzing the human upper body as an inverted pendulum. Through this method, common characteristics of falling behavior are identified to develop a control system that counteracts falling motion with pneumatically produced forces. An emphasis on human-oriented design provides much of the framework for translating the numerical model of forces into a device that prioritizes user comfort without sacrificing assistive performance.

Description
Whether through scaring incarcerated people straight or encouraging rehabilitation through treatment, most people hope that, one way or another, incarceration will alter an individual’s path towards a better life. Current forms of incarceration are not achieving this goal and instead inflict undue amounts of pain (Crewe, 2011; Sykes 1958). In times of deprivation and isolation, some people have found ways to not only persevere, but to thrive. Though these individuals are not commonly the focus of criminal justice literature, there is much value in shifting attention to people thriving in prison including the opportunity to gain knowledge on the multi-faceted nature of well-being broadly and the rehabilitation of incarcerated people more specifically. The current study uses structured interview data from 386 men serving time in a medium-security prison unit to explore the correlates of life satisfaction among people in prison. To identify contributing factors to well-being during incarceration, logistic and multinomial regressions analyze variation in the life satisfaction scores of these incarcerated men. The results from these analyses suggest that perceptions of life meaning, generativity, flourishing, and age are all positively associated with thriving in prison and frequency of experiences with incarceration are not related, positively or negatively, to life satisfaction. This study provides some support to current well-being literature and also introduces complexities to the existing knowledge regarding the relationships between demographics such as race or relationship status, and well-being.

Description
The Soft Robotic Hip Exosuit (SR-HExo) was designed, fabricated, and tested in treadmill walking experiments with healthy participants to gauge effectivity of the suit in assisting locomotion and in expanding the basin of entrainment as a method of rehabilitation. The SR-HExo consists of modular, compliant materials to move freely with a user’s range of motion and is actuated with X-oriented flat fabric pneumatic artificial muscles (X-ff-PAM) that contract when pressurized and can generate 190N of force at 200kPa in a 0.3 sec window. For use in gait assistance experiments, X-ff-PAM actuators were placed anterior and posterior to the right hip joint. Extension assistance and flexion assistance was provided in 10-45% and 50-90% of the gait cycle, respectively. Device effectivity was determined through range of motion (ROM) preservation and hip flexor and extensor muscular activity reduction. While the active suit reduced average hip ROM by 4o from the target 30o, all monitored muscles experienced significant reductions in electrical activity. The gluteus maximus and biceps femoris experienced electrical activity reduction of 13.1% and 6.6% respectively and the iliacus and rectus femoris experienced 10.7% and 27.7% respectively. To test suit rehabilitative potential, the actuators were programmed to apply periodic torque perturbations to induce locomotor entrainment. An X-ff-PAM was contracted at
the subject’s preferred gait frequency and, in randomly ordered increments of 3%, increased up to 15% beyond.
Perturbations located anterior and posterior to the hip were tested separately to assess impact of location on entrainment characteristics. All 11 healthy participants achieved entrainment in all 12 experimental conditions in both
suit orientations. Phase-locking consistently occurred around toe-off phase of the gait cycle (GC). Extension perturbations synchronized earlier in the gait cycle (before 60% GC where peak hip extension occurs) than flexion perturbations (just after 60% GC at the transition from full hip extension to hip flexion), across group averaged results. The study demonstrated the suit can significantly extend the basin of entrainment and improve transient response compared to previously reported results and confirms that a single stable attractor exists during gait entrainment to unidirectional hip perturbations.

Description
The genetic disorder Down syndrome (DS), clinically known as Trisomy 21, is characterized by the presence of either a part or full extra copy of chromosome 21. When compared with children of typical development, children with DS consistently score lower on gross motor skill tasks. Balance specifically is one of the hardest skills for individuals with DS (especially
children) to acquire, and neglecting to train balance early on can predispose individuals with DS to further movement instabilities, injuries, social struggles from activity limitations, and an overall lack of independence. One of the more unique forms of physical activity that requires a large amount of both static and dynamic balance is ballet. Dance-specific therapy has been shown to improve gross motor control functioning and specifically balance in a variety of populations with neuromuscular condions, but the research around ballet-specific therapy for those with DS is lacking. The purpose of this pilot study was to further investigate the effects of ballet-specific training on balance ability and general motor functioning in young students with DS as measured by the Four Square Step Test (FSST), Pediatric Balance Scale (PBS), and the gross and fine motor domains of the Vineland Adaptive Behavior Scale lll (VABS lll). It was hypothesized that participation in the 6-week summer cohort of Ballet Arizona’s Adaptive Dance Program would lead to improved scores on the PBS and VABS lll and decreased test times in the FSST. Improvements were observed for all measures for both participants (sample size n=2), except for P1's FSST, which increased in post-testing by 2.25s. Due to the study design, no conclusive statements can be made about whether the ballet program was responsible for the improvements observed in post-testing. More rigorous research with larger sample sizes (>30) is warranted to more fully understand the impact of an adapted ballet program on the balance ability of young individuals with DS. However, the program is still recommended for young individuals with DS because of the benefits it provides outside of motor skill development.

Description
The human hand comprises complex sensorimotor functions that can be impaired by neurological diseases and traumatic injuries. Effective rehabilitation can bring the impaired hand back to a functional state because of the plasticity of the central nervous system to relearn and remodel the lost synapses in the brain. Current rehabilitation therapies focus on strengthening motor skills, such as grasping, employ multiple objects of varying stiffness and devices that are bulky, costly, and have limited range of stiffness due to the rigid mechanisms employed in their variable stiffness actuators. This research project presents a portable cost-effective soft robotic haptic device with a broad stiffness range that is adjustable and can be utilized in both clinical and home settings. The device eliminates the need for multiple objects by employing a pneumatic soft structure made with highly compliant materials that act as the actuator as well as the structure of the haptic interface. It is made with interchangeable soft elastomeric sleeves that can be customized to include materials of varying stiffness to increase or decrease the stiffness range. The device is fabricated using existing 3D printing technologies, and polymer molding and casting techniques, thus keeping the cost low and throughput high. The haptic interface is linked to either an open-loop system that allows for an increased pressure during usage or closed-loop system that provides pressure regulation in accordance with the stiffness the user specifies. A preliminary evaluation is performed to characterize the effective controllable region of variance in stiffness. Results indicate that the region of controllable stiffness was in the center of the device, where the stiffness appeared to plateau with each increase in pressure. The two control systems are tested to derive relationships between internal pressure, grasping force exertion on the surface, and displacement using multiple probing points on the haptic device. Additional quantitative evaluation is performed with study participants and juxtaposed to a qualitative analysis to ensure adequate perception in compliance variance. Finally, a qualitative evaluation showed that greater than 60% of the trials resulted in the correct perception of stiffness in the haptic device.

Description
Wildlife rehabilitation as a practice in the United States exists in a complicated ethical landscape. The Wildlife Rehabilitator's Code of Ethics exists to guide the profession and states that rehabilitators must respect the wildness and maintain the dignity of an animal in their care. This thesis explores the question: How do the attitudes and actions of wildlife rehabilitators exemplify the ways in which they understand and enact respect for an animal’s dignity and wildness while in their care? Additionally, in what circumstances do rehabilitators align and diverge from each other in their interpretation and demonstration of this respect? These questions were answered through a literature review, interviews with rehabilitators, and site visits to wildlife rehabilitation centers in the Phoenix metropolitan area. My results suggest that rehabilitators are aligned in their understanding of respect for wildness and dignity as it applies to the animals in their care that are actively undergoing rehabilitation. Rehabilitators achieved consensus on the idea that they should interact with the animals as little as possible while providing their medically necessary care. Rehabilitators began to diverge when considering the animals in their sanctuary spaces. Specifically, they varied in their perception of wildness in sanctuary animals, which informed how some saw their responsibilities to the animals. Lesser perceived wildness correlated to increased acceptance of forming affectionate relationships with the sanctuary animals, and even feelings of obligation to form these relationships. Based on my research, I argue that the Wildlife Rehabilitator's Code of Ethics should be revised to reflect the specific boundary that wildlife rehabilitators identified in the rehabilitation space and provide substantive guidance as to what respecting wildness and dignity means in this field.

Description
One of the long-standing issues that has arisen in the sports medicine field is identifying the ideal methodology to optimize recovery following anterior cruciate ligament reconstruction (ACLR). The perioperative period for ACLR is notoriously heterogeneous in nature as it consists of many variables that can impact surgical outcomes. While there has been extensive literature published regarding the efficacy of various recovery and rehabilitation topics, it has been widely acknowledged that certain modalities within the field of ACLR rehabilitation need further high-quality evidence to support their use in clinical practice, such as blood flow restriction (BFR) training. BFR training involves the application of a tourniquet-like cuff to the proximal aspect of a limb prior to exercise; the cuff is inflated so that it occludes venous flow but allows arterial inflow. BFR is usually combined with low-intensity (LI) resistance training, with resistance as low as 20% of one-repetition maximum (1RM). LI-BFR has been used as an emerging clinical modality to combat postoperative atrophy of the quadriceps muscles for those who have undergone ACLR, as these individuals cannot safely tolerate high muscular tension exercise after surgery. Impairments of the quadriceps are the major cause of poor functional status of patients following an otherwise successful ACLR procedure; however, these impairments can be mitigated with preoperative rehabilitation done before surgery. It was hypothesized that the use of a preoperative LI-BFR training protocol could help improve postoperative outcomes following ACLR; primarily, strength and hypertrophy of the quadriceps. When compared with a SHAM control group, subjects who were randomized to a BFR intervention group made greater preoperative strength gains in the quadriceps and recovered quadriceps mass at an earlier timepoint than that of the SHAM group aftersurgery; however, the gains made in strength were not able to be maintained in the 8-week postoperative period. While these results do not support the use of LI-BFR from the short-term perspective after ACLR, follow-up data will be used to investigate trends in re-injury and return to sport rates to evaluate the efficacy of the use of LI-BFR from a long-term perspective.

Description
With an aging population, the number of later in life health related incidents like stroke stand to become more prevalent. Unfortunately, the majority those who are most at risk for debilitating heath episodes are either uninsured or under insured when it comes to long term physical/occupational therapy. As insurance companies lower coverage and/or raise prices of plans with sufficient coverage, it can be expected that the proportion of uninsured/under insured to fully insured people will rise. To address this, lower cost alternative methods of treatment must be developed so people can obtain the treated required for a sufficient recovery. The presented robotic glove employs low cost fabric soft pneumatic actuators which use a closed loop feedback controller based on readings from embedded soft sensors. This provides the device with proprioceptive abilities for the dynamic control of each independent actuator. Force and fatigue tests were performed to determine the viability of the actuator design. A Box and Block test along with a motion capture study was completed to study the performance of the device. This paper presents the design and classification of a soft robotic glove with a feedback controller as a at-home stroke rehabilitation device.
