A prospective, double-blind, pilot, randomized, controlled trial of an "embodied" virtual reality intervention for adults with low back pain

Adults with chronic low back pain, disability, moderate-to-severe pain, and high fear of movement and reinjury were recruited into a trial of a novel, automated, digital therapeutics, virtual reality, psychological intervention for pain (DTxP). We conducted a 3-arm, prospective, double-blind, pilot, randomized, controlled trial comparing DTxP with a sham placebo comparator and an open-label standard care. Participants were enrolled for 6 to 8 weeks, after which, the standard care control arm were rerandomized to receive either the DTxP or sham placebo. Forty-two participants completed assessments at baseline, immediately posttreatment (6-8 weeks), 9-week, and 5-month follow-up. We found that participants in the DTxP group reported greater reductions in fear of movement and better global impression of change when compared with sham placebo and standard care post treatment. No other group differences were noted at posttreatment or follow-up. When compared with baseline, participants in the DTxP group reported lower disability at 5-month follow-up, lower pain interference and fear of movement post treatment and follow-up, and lower pain intensity at posttreatment. The sham placebo group also reported lower disability and fear of movement at 5-month follow-up compared with baseline. Standard care did not report any significant changes. There were a number of adverse events, with one participant reporting a serious adverse event in the sham placebo, which was not related to treatment. No substantial changes in medications were noted, and participants in the DTxP group reported positive gaming experiences

The Effectiveness Of Virtual Humans Vs. Pre-recorded Humans In A Standardized Patient Performance Assessment

A Standardized Patient (SP) is a trained actor who portrays a particular illness to provide training to medical students and professionals. SPs primarily use written scripts and additional paper-based training for preparation of practical and board exams. Many institutions use various methods for training such as hiring preceptors for reenactment of scenarios, viewing archived videos, and computer based training. Currently, the training that is available can be enhanced to improve the level of quality of standardized patients. The following research is examining current processes in standardized patient training and investigating new methods for clinical skills education in SPs. The modality that is selected for training can possibly affect the performance of the actual SP case. This paper explains the results of a study that investigates if there is a difference in the results of an SP performance assessment. This difference can be seen when comparing a virtual human modality to that of a pre-recorded human modality for standardized patient training. The sample population navigates through an interactive computer based training module which provides informational content on what the roles of an SP are, training objectives, a practice session, and an interactive performance assessment with a simulated Virtual Human medical student. Half of the subjects interact with an animated virtual human medical student while the other half interacts with a pre-recorded human. The interactions from this assessment are audio-recorded, transcribed, and then graded to see how the two modalities compare. If the performance when using virtual humans for standardized patients is equal to or superior to pre-recorded humans, this can be utilized as a part task trainer that brings standardized patients to a higher level of effectiveness and standardization. In addition, if executed properly, this tool could potentially be used as a part task trainer which could provide savings in training time, resources, budget, and staff to military and civilian healthcare facilities

Decoding Neural Signals with Computational Models: A Systematic Review of Invasive BMI

There are significant milestones in modern human's civilization in which mankind stepped into a different level of life with a new spectrum of possibilities and comfort. From fire-lighting technology and wheeled wagons to writing, electricity and the Internet, each one changed our lives dramatically. In this paper, we take a deep look into the invasive Brain Machine Interface (BMI), an ambitious and cutting-edge technology which has the potential to be another important milestone in human civilization. Not only beneficial for patients with severe medical conditions, the invasive BMI technology can significantly impact different technologies and almost every aspect of human's life. We review the biological and engineering concepts that underpin the implementation of BMI applications. There are various essential techniques that are necessary for making invasive BMI applications a reality. We review these through providing an analysis of (i) possible applications of invasive BMI technology, (ii) the methods and devices for detecting and decoding brain signals, as well as (iii) possible options for stimulating signals into human's brain. Finally, we discuss the challenges and opportunities of invasive BMI for further development in the area.Comment: 51 pages, 14 figures, review articl

Sonic utopia and social dystopia in the music of Hendrix, Reznor and Deadmau5

Twentieth-century popular music is fundamentally associated with electronics in its creation and recording, consumption, modes of dissemination, and playback. Traditional musical analysis, placing primacy on notated music, generally focuses on harmony, melody, and form, with issues of timbre and postproduction effects remaining largely unstudied. Interdisciplinary methodological practices address these limitations and can help broaden the analytical scope of popular idioms. Grounded in Jacques Attali's critical theories about the political economy of music, this dissertation investigates how the subversive noise of electronic sound challenges a controlling order and predicts broad cultural realignment. This study demonstrates how electronic noise, as an extra-musical element, creates modern soundscapes that require a new mapping of musical form and social intent. I further argue that the use of electronics in popular music signifies a technologically-obsessed postwar American culture moving rapidly towards an online digital revolution. I examine how electronic music technology introduces new sounds concurrent with generational shifts, projects imagined utopian and dystopian futures, and engages the tension between automated modern life and emotionally validating musical communities in real and virtual spaces. Chapter One synthesizes this interdisciplinary American studies project with the growing scholarship of sound studies in order to construct theoretical models for popular music analysis drawn from the fields of musicology, history, and science and technology studies. Chapter Two traces the emergence of the electronic synthesizer as a new sound that facilitated the transition of a technological postwar American culture into the politicized counterculture of the 1960s. The following three chapters provide case studies of individual popular artists' use of electronic music technology to express societal and political discontent: 1) Jimi Hendrix's application of distortion and stereo effects to narrate an Afrofuturist consciousness in the 1960s; 2) Trent Reznor's aggressive industrial rejection of Conservatism in the 1980s; and 3) Deadmau5's mediation of online life through computer-based production and performance in the 2000s. Lastly, this study extends existing discussions within sound studies to consider the cultural implications of music technology, noise politics, electronic timbre, multitrack audio, digital analytical techniques and online communities built through social media
