Mind-body interventions for chronic pain in older adults: a structured review.

Pain Med. 2007 May;8(4):359-75

Authors: Morone NE, Greco CM

Study Design. We conducted a structured review of eight mind-body interventions for older adults with chronic nonmalignant pain. Objectives. To evaluate the feasibility, safety, and evidence for pain reduction in older adults with chronic nonmalignant pain in the following mind-body therapies: biofeedback, progressive muscle relaxation, meditation, guided imagery, hypnosis, tai chi, qi gong, and yoga. Methods. Relevant studies in the MEDLINE, PsycINFO, AMED, and CINAHL databases were located. A manual search of references from retrieved articles was also conducted. Of 381 articles retrieved through search strategies, 20 trials that included older adults with chronic pain were reviewed. Results. Fourteen articles included participants aged 50 years and above, while only two of these focused specifically on persons aged >/=65 years. An additional six articles included persons aged >/=50 years. Fourteen articles were controlled trials. There is some support for the efficacy of progressive muscle relaxation plus guided imagery for osteoarthritis pain. There is limited support for meditation and tai chi for improving function or coping in older adults with low back pain or osteoarthritis. In an uncontrolled biofeedback trial that stratified by age group, both older and younger adults had significant reductions in pain following the intervention. Several studies included older adults, but did not analyze benefits by age. Tai chi, yoga, hypnosis, and progressive muscle relaxation were significantly associated with pain reduction in these studies. Conclusion. The eight mind-body interventions reviewed are feasible in an older population. They are likely safe, but many of the therapies included modifications tailored for older adults. There is not yet sufficient evidence to conclude that these eight mind-body interventions reduce chronic nonmalignant pain in older adults. Further research should focus on larger, clinical trials of mind-body interventions to answer this question.

EEG-based assessment of driver cognitive responses in a dynamic virtual-reality driving environment.

IEEE Trans Biomed Eng. 2007 Jul;54(7):1349-52

Authors: Lin CT, Chung IF, Ko LW, Chen YC, Liang SF, Duann JR

Accidents caused by errors and failures in human performance among traffic fatalities have a high death rate and become an important issue in public security. They are mainly caused by the failures of the drivers to perceive the changes of the traffic lights or the unexpected conditions happening accidentally on the roads. In this paper, we devised a quantitative analysis for assessing driver's cognitive responses by investigating the neurobiological information underlying electroencephalographic (EEG) brain dynamics in traffic-light experiments in a virtual-reality (VR) dynamic driving environment. The VR technique allows subjects to interact directly with the moving virtual environment instead of monotonic auditory and visual stimuli, thereby provides interactive and realistic tasks without the risk of operating on an actual machine. Independent component analysis (ICA) is used to separate and extract noise-free ERP signals from the multi-channel EEG signals. A temporal filter is used to solve the time-alignment problem of ERP features and principle component analysis (PCA) is used to reduce feature dimensions. The dimension-reduced features are then input to a self-constructing neural fuzzy inference network (SONFIN) to recognize different brain potentials stimulated by red/green/yellow traffic events, the accuracy can be reached 87% in average eight subjects in this visual-stimuli ERP experiment. It demonstrates the feasibility of detecting and analyzing multiple streams of ERP signals that represent operators' cognitive states and responses to task events.

Jason Green, CEO of Florida-based Medical Development International (MDI) announced that experts at his company have applied artificial intelligence to produce original, three-dimensional paintings.

From the press release:

Most computers store individual instructions as code with each instruction given a unique number; the simplest computers perform a handful of different instructions, while the more complex computers have several hundred to choose from.

Green took programming capability one-step further by producing thousands of images using a set color scheme and style from multiple images simultaneously created on multiple machines. The best of these images are then rendered at extremely high resolutions.

Green's "Virtual Van Gogh" takes High-Definition to an entirely different level. While the best High-Definition television (HDTV) currently available produces an image at 1980 x 1080 pixels, Green's program render's the painting's resolution to 7500 x 5000 taking more than 156 hours.

Brain-computer interface systems: progress and prospects.

Expert Rev Med Devices. 2007 Jul;4(4):463-474

Authors: Allison BZ, Wolpaw EW, Wolpaw JR

Brain-computer interface (BCI) systems support communication through direct measures of neural activity without muscle activity. BCIs may provide the best and sometimes the only communication option for users disabled by the most severe neuromuscular disorders and may eventually become useful to less severely disabled and/or healthy individuals across a wide range of applications. This review discusses the structure and functions of BCI systems, clarifies terminology and addresses practical applications. Progress and opportunities in the field are also identified and explicated.

An excerpt from a paper by Mohammed Reza Rikhtegaran about the relationship between Technology, Man and Spirituality:

Is it possible to bring technology and spirituality together? Usually technology is referred to as an instrument of mass production related to profit and loss. But is technology merely an instrument? Regarding technology as mere instrument is correct but it keeps us from understanding the essence of technology and its relation with truth.

Unconcealedness and concealedness of Being are always together, and every stage of unconcealedness is related to its corresponding concealedness. The Greeks call this unconcealedness Aletheia, that is, Truth.1 It is quite strange that contemplation about the essence of technology brings us to considering and understanding the unconcealedness and concealedness of the truth. In other words the essence of technology is nothing technical, just as the essence of a tree is not itself a tree which can be seen among other trees.

The truth or essence of technology, is the disposing and dispossession of raw material for consumption through which mastery over the universe is achieved. In other words in the realm of technology, man is confronted with a sort of unconcealedness, based on which he uses things for the mere purpose of consumption and thereafter achieving the mastery. With this dispossession the relationality of man with things goes through a transformation and things turn into fixed stock. Dispossession is the essence of technology.2

The question is, how is it possible that technology — the basis of which is Western, and, worldly and is rooted in the left (wrong) dimension of human existence and the preoccupation of which is the domination of, and mastery over the material universe, be brought under the domination of the right dimension of the human existence? How to make it spiritually oriented and Eastern, while preserving it, and thereby sanctify it? It was mentioned that technology is based on a particular unconcealedness and a special relationality with Being. In other words, technology is itself a culture and considering its etymology culture is a kind of interpretation of earth. Thus, the very issue may be put in a different way, i.e., how is it possible to bring forth a union between the culture of technology and the culture of spirituality and at the same time retain both. The crux of the problem, therefore, is as to which cultural aspect we are to transfer the culture of technology, in other words, in which culture is it to be included. It is the question of the confrontation of the two cultures. It is the confrontation between the left (wrong) dimension and the right dimension of human existence. Therefore, there emerges the well-known confrontation between the East and the West. However, the very essence of the West and its culture which is the basis of technology, is earthly, whereas the essence of the East and its culture is the renunciation of this world. If technology is to be adopted by Eastern culture and knowledge, there shall be contradiction between the two. Thus a union between the two is not possible and the desire to have technology along with Eastern spirituality is wishful thinking.

Virtual reality as a leisure activity for young adults with physical and intellectual disabilities.

Res Dev Disabil. 2007 Jun 20;

Authors: Yalon-Chamovitz S, Weiss PL

Participation in leisure activities is a fundamental human right and an important factor of quality of life. Adults with intellectual disabilities (ID) and physical disabilities often experience limited opportunities to participate in leisure activities, virtual reality (VR) technologies may serve to broaden their repertoire of accessible leisure activities. Although the use of VR in rehabilitation has grown over the past decade, few applications have been reported for people with ID. Thirty-three men and women with moderate ID and severe cerebral palsy participated in the study. Each participant in the experimental group (n=17) took part in VR activity two to three times weekly for 12 weeks. Virtual games were provided via GestureTek's Gesture Xtreme video capture VR system. The VR-based activities were perceived by the participants to be enjoyable and successful. Moreover, participants demonstrated clear preferences, initiation and learning. They performed consistently and maintained a high level of interest throughout the intervention period. VR appears to provide varied and motivating opportunities for leisure activities among young adults with intellectual and physical disabilities. Its ease of use and adaptability make it a feasible option for this population.

Use of Virtual Reality Distraction to Reduce Claustrophobia Symptoms during a Mock Magnetic Resonance Imaging Brain Scan: A Case Report.

Cyberpsychol Behav. 2007 Jun;10(3):485-8

Authors: Garcia-Palacios A, Hoffman HG, Richards TR, Seibel EJ, Sharar SR

The present case series with two patients explored whether virtual reality (VR) distraction could reduce claustrophobia symptoms during a mock magnetic resonance imaging (MRI) brain scan. Two patients who met DSM-IV criteria for specific phobia, situational type (i.e., claustrophobia) reported high levels of anxiety during a mock 10-min MRI procedure with no VR, and asked to terminate the scan early. The patients were randomly assigned to receive either VR or music distraction for their second scan attempt. When immersed in an illusory three-dimensional (3D) virtual world named SnowWorld, patient 1 was able to complete a 10-min mock scan with low anxiety and reported an increase in self-efficacy afterwards. Patient 2 received "music only" distraction during her second scan but was still not able to complete a 10-min scan and asked to terminate her second scan early. These results suggest that immersive VR may prove effective at temporarily reducing claustrophobia symptoms during MRI scans and music may prove less effective.

I found two very interesting posts in Mauro Cherubini's blog about the use of techology in spiritual practice.

The first project - for this we pray - is an art installation inspired by the tradition of lighting candles during prayer.

for this we pray brings the experience of reflection to the everyday world of the jaded digital generation. Users select one of several prayer cards, and hold it close to a wall-mounted “shrine” reminiscent of a stained-glass window. The prayer card is recognized via RFID, and a light is turned on. As more prayers are "read" the shrine will fill with light.

the second post points to an article that examines how technology can be used in religious life:

Wyche, S. P., Hayes, G. R., Harvel, L. D., and Grinter, R. E. (2006). Technology in spiritual formation: an exploratory study of computer mediated religious communications. In CSCW ’06: Proceedings of the 2006 20th anniversary conference on Computer supported cooperative work, pages 199–208, New York, NY, USA. ACM Press. [pdf]

———

This paper aims at explaining the use of technology in religious life. The author performed a series of intervies with Protestant Ministers. Most pastors responded with a list of duties including educating the laity, preaching, and communication. More in details they reported using thechnological means to organize Bible study groups, for the pastoral care of the laity such as reaching sick parishioners or conunseling those in spiritual or personal crisis.

A good part of the article focus on thechnological enhancement to preaching and presentation. An interesting reported finding is that altough Ministers reported using commercial products for their presentations such as PowerPoint or Keynote, they expressed their misgivings about the fact that these software were designed with generic purposes in mind and that they do not support the peculiarities of spiritual training or presentation.

Some pastors expressed their feelings about the fact that using technology is essential for the church to be ‘contemporary’ but at the same time it is a matter of negotiation: a tradeoff between ‘relevance’ and ‘reverence’, but also a tradeoff between connection and distraction, remoteness and actual encounters. E. G., for spiritual practices solitude might be important.

Finally the authors reported interestingly that parishioners used technological access to spiritual material at work. So, we observe an ‘infiltration’ of domestic life in working settings. This allowed them to practice during the week instead of waiting for Sunday.

On a critical note, focusing the study on a single religion might have somehow biased the results. It might be interesting to broaden the spectrum of analysis to see if the same results apply.

I am very intrigued by the potential of bringing together technology and spirituality. So I decided to create a new category "technology and spirituality", and I hope to find soon new examples of this approach

The city is no longer built of concrete, a static posture no longer endures. Our surroundings have become a malleable space which can be warped, spliced and expanded at will. We no longer stand in one place alone, a mass convergence of coordinates is taking place beneath our feet. As we traverse these points of perpetual motion we are enclosed by structures of elsewhere, met with the sliding walls of other places which lead us through a never ending maze. Shrouded in alternative layers of space, we escape to another confinement through the mesh of new media.

As our presence is extended by the veins of technology our sense of space is transformed, our nervous system stems through endless reaches of universal skin. Our eyes see through a thousand windows, each with a different view, a collision of a multitude of global sounds meets our ears, our fingers pass beyond tiers of materiality.

But can we see what is before us? Are we listening to the resonance of our surroundings? Can we feel the texture of this place?

Engaged in distant or imaginary space, we flick through the channels with our remote control and choose when to plug in when to switch off. But as we are absorbed by these electronic pulses are we disappearing from the here and now?

Personal technologies offer a kaleidoscopic sensation of a multi-layered existence, but perhaps may also provide a microscope by which to examine the place which we are in at this moment.

From Pentagon to Merge Next-Gen Binoculars With Soldiers' Brains by Sharon Weinberger, Wired:

"U.S. Special Forces may soon have a strange and powerful new weapon in their arsenal: a pair of high-tech binoculars 10 times more powerful than anything available today, augmented by an alerting system that literally taps the wearer's prefrontal cortex to warn of furtive threats detected by the soldier's subconscious.

In a new effort dubbed "Luke's Binoculars" -- after the high-tech binoculars Luke Skywalker uses in Star Wars -- the Defense Advanced Research Projects Agency is setting out to create its own version of this science-fiction hardware. And while the Pentagon's R&D arm often focuses on technologies 20 years out, this new effort is dramatically different -- Darpa says it expects to have prototypes in the hands of soldiers in three years...

The most far-reaching component of the binocs has nothing to do with the optics: it's Darpa's aspirations to integrate EEG electrodes that monitor the wearer's neural signals, cueing soldiers to recognize targets faster than the unaided brain could on its own. The idea is that EEG can spot "neural signatures" for target detection before the conscious mind becomes aware of a potential threat or target."
