Feasibility of Wii Fit Training to Improve Clinical Measures of Balance in Older Adults

Background and purpose: Numerous interventions have been proposed to improve balance in older adults with varying degrees of success. A novel approach may be to use an off-the-shelf video game system utilizing real-time force feedback to train older adults. The purpose of this study is to investigate the feasibility of using Nintendo's Wii Fit for training to improve clinical measures of balance in older adults and to retain the improvements after a period of time. Methods: Twelve healthy older adults (aged >70 years) were randomly divided into two groups. The experimental group completed training using Nintendo's Wii Fit game three times a week for 3 weeks while the control group continued with normal activities. Four clinical measures of balance were assessed before training, 1 week after training, and 1 month after training: Berg Balance Scale (BBS), Fullerton Advanced Balance (FAB) scale, Functional Reach (FR), and Timed Up and Go (TUG). Friedman two-way analysis of variance by ranks was conducted on the control and experimental group to determine if training using the Wii Balance Board with Wii Fit had an influence on clinical measures of balance. Results: Nine older adults completed the study (experimental group n = 4, control group n = 5). The experimental group significantly increased their BBS after training while the control group did not. There was no significant change for either group with FAB, FR, and TUG. Conclusion: Balance training with Nintendo's Wii Fit may be a novel way for older adults to improve balance as measured by the BBS.

Harry Potter and the Theory of Things

This thesis investigates the boundaries between body and object in J.K. Rowling’s Harry Potter series, seven children’s literature novels published between 1997 and 2007. Lord Voldemort, Rowling’s villain, creates Horcruxes—objects that contain fragments of his soul—in order to ensure his immortality. As vessels for human soul, these objects rupture the boundaries between body and object and become “things.” Using contemporary thing theorists including John Plotz and materialists Jean Baudrillard and Walter Benjamin, I look at Voldemort’s Horcruxes as transgressive, liminal, unclassifiable entities in the first chapter. If objects can occupy the juncture between body and object, then bodies can as well. Dementors and Inferi, dark creatures that Rowling introduces throughout the series, live devoid of soul. Voldemort, too, becomes a thing as he splits his soul and creates Horcruxes. These soulless bodies are uncanny entities, provoking fear, revulsion, nausea, and the loss of language. In the second chapter, I use Sigmund Freud’s theorization of the uncanny as well as literary critic Kelly Hurley to investigate how Dementors, Inferi, and Voldemort exist as body-turned-object things at the juncture between life and death. As Voldemort increasingly invests his immaterial soul into material objects, he physically and spiritually degenerates, transforming from the young, handsome Tom Marvolo Riddle into the snake-like villain that murdered Harry’s parents and countless others. During his quest to find and destroy Voldemort’s Horcruxes, Harry encounters a different type of object, the Deathly Hallows. Although similarly accessing boundaries between body/object, life/death, and materiality/immateriality, the three Deathly Hallows do not transgress these boundaries. Through the Deathly Hallows, Rowling provides an alternative to thingification: objects that enable boundaries to fluctuate, but not breakdown. In the third chapter, I return to thing theorists, Baudrillard, and Benjamin to study how the Deathly Hallows resist thingification by not transgressing the boundaries between body and object.
