Intelligent multimedia transmission for back pain treatment
Copyright @ 2002 EUNITERemote, multimedia-based, collaboration in back pain treatment is an option which only recently has come to the attention of clinicians and IT providers. The take up of such applications will inevitably depend on their ability to produce an acceptable level of service over congested and unreliable public networks However, although the problem of multimedia application-level performance is closely linked to both the user perspective of the experience as well as to the service provided by the underlying network, it is rarely studied from an integrated viewpoint. To alleviate this problem in the context of a multimedia application, a method is proposed in this paper for obtaining a priority order of low-level Quality of Service parameters, which would ensure that user-level Quality of Perception is maintained at an optimum level. Thus we present an approach that integrates technical concerns with user perceptual considerations for intelligent decision-making in the construction of tailor-made multimedia communication protocols. The proposed approach, based on multicriteria decision making, incorporates not only classical networking considerations, but, indeed, user preferences as well. Moreover, our approach also opens the possibility for such protocols to dynamically adapt based on a changing operating environment and user preferences

While current available clinical approaches have proven to be valid interventions, they are expensive and can often fail in providing efficient pain measurements. The increase in the prevalence of pain calls for more intuitive pain assessment solutions. Computerized alternatives have already been proposed both in the literature and in commerce, but may lack essential qualities such as accuracy of the collected clinical information and effective patient-clinician interaction. In response to this concern, 3-dimensional (3D) technology could become the innovative intervention needed to support and improve the pain assessment process.
Objective: The purpose of this analysis was to describe qualitative findings from a study which was designed to explore patientsâ perceptions of adopting 3D technology in the assessment of their pain experience related to important themes that might positively or negatively influence the quality of the pain assessment process.
Methods: The perceptions of 60 individuals with some form of pain in the area of Greater London were collected through semi-structured interviews. Of the 60 respondents, 24 (43%) produced usable responses and were analyzed for content using principles of the grounded theory approach and thematic analysis, in order to gain insight into the participantsâ beliefs and attitudes towards adopting 3D technology in pain assessment.
Results: The analysis identified 4 high-level core themes that were representative of the participantsâ responses. These themes indicated that most respondents valued âthe potential of 3D technology to facilitate better assessment of painâ as the most useful outcome of adopting a 3D approach. Respondents also expressed their opinions on the usability of the 3D approach, with no important concerns reported about its perceived ease of use. Our findings finally, showed that respondents appreciated the perceived clinical utility of the proposed approach, which could further have an influence on their intention to use it.
Conclusions: These findings highlighted factors that are seen as essential for improving the assessment of pain, and demonstrated the need for a strong focus on patient-clinician communication. The participants of this analysis believed that the introduction of 3D technology in the process might be a useful mechanism for such a positive health care outcome. The studyâs findings could also be used to make recommendations concerning the potential for inclusion of 3D technology in current clinical pain tools for the purpose of improving the quality of health care

Visualization of back pain data-A 3-D solution
Traditional approaches to gathering and visualizing pain data rely on two-dimensional (2-D) human body models, where different types of sensation are recorded with various monochrome symbols. We proposean alternative that uses a three-dimensional (3-D) representation of the human body, which can be marked in color to visualize and record pain data

Intelligent multimedia communication for enhanced medical e-collaboration in back pain treatment
This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2004 SAGE PublicationsRemote, multimedia-based, collaboration in back pain treatment is an option which only recently has come to the attention of clinicians and IT providers. The take-up of such applications will inevitably depend on their ability to produce an acceptable level of service over congested and unreliable public networks. However, although the problem of multimedia application-level performance is closely linked to both the user perspective of the experience as well as to the service provided by the underlying network, it is rarely studied from an integrated viewpoint. To alleviate this problem, we propose an intelligent mechanism that integrates user-related requirements with the more technical characterization of quality of service, obtaining a priority order of low-level quality of service parameters, which would ensure that user-centred quality of perception is maintained at an optimum level. We show how our framework is capable of suggesting appropriately tailored transmission protocols, by incorporating user requirements in the remote delivery of e-health solutions
Intelligent protocol adaptation for enhanced medical e-collaboration
Copyright @ 2003 AAAIDistributed multimedia e-health applications have a set specific requirements which must be taken into account effective use is to be made of the limited resources provided by public telecommunication networks. Moreover, there an architectural gap between the provision of network-level Quality of Service (QoS) and user requirements of e-health applications. In this paper, we address the problem bridging this gap from a multi-attribute decision-making perspective in the context of a remote collaborative environment for back pain treatment. We propose intelligent mechanism that integrates user- related requirements with the more technical characterisation Quality of Service. We show how our framework is capable of suggesting appropriately tailored transmission protocols, by incorporating user requirements in the remote delivery e-health solutions

3-D pain drawings-mobile data collection using a PDA
A large number of the adult population suffers from some kind of back pain during their lifetime. Part of the process of diagnosing and treating such back pain is for a clinician to
collect information as to the type and location of the pain that is being suffered.Traditional approaches to gathering and visualizing this pain data have relied on simple 2-D representations of the human body, where different types of sensation are recorded with various monochrome symbols. Although patients have been shown to prefer such drawings to traditional questionnaires, these pain drawings can be limited in their ability to accurately record pain. The work described in this paper proposes an alternative that uses a 3-D representation of the human body, which can be marked in color to visualize and record the pain data. This study has shown that the new approach is a promising development in this area of medical practice and has been positively received by patients and clinicians alike
Pain management following new and long-standing spinal cord injury: A pilot study of changes in pain intensity experienced during the day
The aim of the study was to examine variations in pain intensity during the day experienced by patients with spinal cord injury. Fourteen consecutive patients had clinical and demographic data recorded. Pain intensity was recorded using a Graphic Rating Scale (GRS) at 2-3-h intervals. Patients were grouped according to maximum GRS into mild and severe groups at assessment (T0). Changes of one-third in GRS were deemed clinically significant. Eight men and six women (mean age 53.1; SD 16.5; range 28-75) were studied. Seven patients with mild pain tended to deteriorate and those with severe pain to improve. Eight patients demonstrated clinically significant changes. These findings suggest inadequate pain control early morning for one group and increasing pain during the day for another. Use of such simple scores over time would enhance pain rehabilitation for all spinal cord injury patients. Usual GRS reporting may mask clinically significant, treatable, changes in pain
Using geographical information systems for management of back-pain data
This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2002 MCB UP LtdIn the medical world, statistical visualisation has largely been confined to the realm of relatively simple geographical applications. This remains the case, even though hospitals have been collecting spatial data relating to patients. In particular, hospitals have a wealth of back pain information, which includes pain drawings, usually detailing the spatial distribution and type of pain suffered by back-pain patients. Proposes several technological solutions, which permit data within back-pain datasets to be digitally linked to the pain drawings in order to provide methods of computer-based data management and analysis. In particular, proposes the use of geographical information systems (GIS), up till now a tool used mainly in the geographic and cartographic domains, to provide novel and powerful ways of visualising and managing back-pain data. A comparative evaluation of the proposed solutions shows that, although adding complexity and cost, the GIS-based solution is the one most appropriate for visualisation and analysis of back-pain datasets
Microscopic Oscillations in the Quantum Nucleation of Vortices Subject to Periodic Pinning Potential in a Thin Superconductor
We present a theory for the decay of a supercurrent through nucleation of
vortex-antivortex pairs in a two-dimensional superconductor in the presence of
dissipation and of a periodic pinning potential. Through a powerful quantum
electrodynamics formulation of the problem we show that the nucleation rate
develops oscillations in its current-density dependence which are connected to
the pinning periodicity. A remnant of the dissipation-driven localization
transition is present, and an estimate of the nucleation rate suggests that
these effects might be observable in real thin superconductors.Comment: REVTeX file, 4 pages in two-column mode, 1 Postscript figure, to
