Motor behavior is prone to variable conditions and deviates further in disorders affecting the nervous system. A combination of environmental and neural factors impacts the amount of uncertainty. Although the influence of these factors on estimating endpoint positions have been examined, the role of limb configuration on endpoint variability has been mostly ignored. Characterizing the influence of arm configuration (i.e. intrinsic factors) would allow greater comprehension of sensorimotor integration and assist in interpreting exaggerated movement variability in patients. In this study, subjects were placed in a 3-D virtual reality environment and were asked to move from a starting position to one of three targets in the frontal plane with and without visual feedback of the moving limb. The alternating of visual feedback during trials increased uncertainty between the planning and execution phases. The starting limb configurations, adducted and abducted, were varied in separate blocks. Arm configurations were setup by rotating along the shoulder-hand axis to maintain endpoint position. The investigation hypothesized: 1) patterns of endpoint variability of movements would be dependent upon the starting arm configuration and 2) any differences observed would be more apparent in conditions that withheld visual feedback. The results indicated that there were differences in endpoint variability between arm configurations in both visual conditions, but differences in variability increased when visual feedback was withheld. Overall this suggests that in the presence of visual feedback, planning of movements in 3D space mostly uses coordinates that are arm configuration independent. On the other hand, without visual feedback, planning of movements in 3D space relies substantially on intrinsic coordinates.

Cochlear implants are electronic medical devices that create hearing capabilities in those with inner ear damage that results in total or partial hearing loss. The decision to get a cochlear implant can be difficult and controversial. Cochlear implants have many physical and social impacts on cochlear implant users. The aim of this study was to evaluate how patient narratives written by people with cochlear implants (or their caregivers) express issues of quality of life and personhood related to the use of this medical device. The methodology used to answer this question was a content analysis of patient narratives. The content analysis was done using grounded theory and the constant comparative method. Two sensitizing concepts, quality of life and personhood, were used and became the large umbrella themes found in the narratives. Under the major theme of quality of life, the sub-themes that emerged were improved hearing, improved communication skills, and assimilation into the hearing world. Under the major theme of personhood, the sub-themes that emerged were confidence, self-image, and technology and the body. Another major theme, importance of education, also emerged. In general, cochlear implant users and their caregivers expressed in their narratives that cochlear implants have positive effects on the quality of life of cochlear implant users. This is because almost all of the narrative writers reported improved hearing, improved communication skills, and better assimilation into the hearing world. In addition, it was found that cochlear implants do not have a significant affect on the actual personal identity of cochlear implant users, though they do make them more confident. The majority of cochlear implant users expressed that they view the cochlear implant device as an assistive tool they use as opposed to a part of themselves. Lastly, there is a need for more awareness of or access to education and therapy for cochlear implant users.

The Wonderbox research project was the product of a creative health collaboration between the Edson College of Nursing and Health Innovation and the Herberger Institute for Design and the Arts at Arizona State University, as well as the Childsplay AZ theater in Tempe, Arizona. This ongoing project began in the summer of 2021. It was funded by the National Endowment for the Arts, and IRB approval was obtained for the project. Each participant signed informed consent documents prior to the start of the survey and the intervention. This research project aimed to explore ways in which stress can be alleviated in parents and caregivers who have medically complex children using creative play and interactive theater interventions. This study used surveys to determine how the Wonderbox activities impacted the perceived stress, well-being, overall family functioning, and quality of life of parents who have medically complex children. This study consisted of parents or caregivers of children between the ages of 6 and 17 with any type of medical complexity who spoke English. There were 31 families who participated in this study. The family APGAR (family functioning), perceived stress scale, quality of life evaluation, and the WHO-5 well-being index were measured before and following the intervention. The quality of life evaluation post-test measure was shown to be statistically significant, and the perceived stress increased but was not statistically significant. The Family APGAR had no change. In qualitative results, only five families reported their results in ClassDojo, and there was no communication between the researchers and the parents of these children. Overall, the study was successful in significantly improving quality of life and caused no harm to the participants in other areas of evaluation. Future studies should consider broadening the size of the population of the next cohort, as well as promoting better communication among these families to obtain more qualitative results.
