A review of the role of assistive technology for people with dementia in the hours of darkness.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The objective of this literature review is to evaluate reported healthcare technologies appropriate to night time care. This paper summarises and categorises the current evidence base. In all, 131 abstracts were returned from a database search, yielding fifty four relevant papers which were considered in detail. While night-time specific studies identified very few papers (4 papers, 7%), most of the more general AT findings could be adopted to benefit night-time assistance. Studies have used technology for prompting and reminding as loss of time and forgetfulness are major problems; for monitoring daily activities in a sen...

Identification of patients with congestive heart failure using different neural networks approaches.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A new technique for identification of patients with congestive heart failure (CHF) from normal controls is investigated in this paper using spectral analysis and neural networks. The identification system consists of two parts: feature extraction part and classification part. The feature extraction part uses the method of approximate spectral density estimation of R-R-Intervals (RRI) data by implementing the soft decision sub-band decomposition technique. In the classification part, two different methods of machine learning approaches with neural networks are implemented and compared in their performances. Those approa...

Pick to place trajectories in human arm training environment.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This paper presents a new method of trajectory planning in rehabilitation robotics. First were measured in healthy subject the pick to place trajectories while haptic robot is in zero impedance space. B-spline approximation is used to mathematically define the measured paths. This trajectory path serves as a central line for the rounding haptic tunnel. In addition to radial elastic and damping force an optional guidance force can be applied along the tunnel to reach the place point. The B-spline control points were observed around the robot and arm workspace. The trajectory path defined with B-splines is compared with ...

3D visualized robot assisted reduction of femoral shaft fractures: Evaluation in exposed cadaveric bones.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The main problems in intra-medullary nailing of femoral shaft-fractures are leg-length discrepancies and rotational differences with an incidence of 2-18% and 20-40% respectively. These may lead to severe postoperative sequelae such as additional correctional operations and difficult rehabilitation. Insufficient visualization can be considered the main reason for these complications. Finally, retention of the fragments in the correct alignment before nail insertion is difficult. To overcome these problems we established a robotic telemanipulator system to support the reduction process. It was evaluated in 30 fractures ...

Model and algorithmic framework for detection and correction of cognitive errors.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This paper outlines an approach that we are taking for elder-care applications in the smart home, involving cognitive errors and their compensation. Our approach involves high level modeling of daily activities of the elderly by breaking down these activities into smaller units, which can then be automatically recognized at a low level by collections of sensors placed in the homes of the elderly. This separation allows us to employ plan recognition algorithms and systems at a high level, while developing stand-alone activity recognition algorithms and systems at a low level. It also allows the mixing and matching of mu...

Enabling affordable and efficiently deployed location based smart home systems.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
With the obvious eldercare capabilities of smart environments it is a question of "when", rather than "if", these technologies will be routinely integrated into the design of future houses. In the meantime, health monitoring applications must be integrated into already complete home environments. However, there is significant effort involved in installing the hardware necessary to monitor the movements of an elder throughout an environment. Our work seeks to address the high infrastructure requirements of traditional location-based smart home systems by developing an extremely low infrastructure localisation technique....

A review of assistive technologies for people with Parkinson's disease.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The population is aging and with this, the incidence of age related diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD) are increasing. Assistive Technology (AT) is viewed as one of the possible solutions which can be used to meet the needs of persons suffering from PD. AT can enable a person to carry out a task which otherwise they would be unable to undertake independently. An AT can have many functions which range from helping people to use a computer, to monitoring someone's condition. Within this paper we attempt to categorise the different types of AT for persons with PD. Each of the technologi...

Cortical mechanisms of normal and abnormal processing in the visual system, Part 1Spatial vision, amblyopia, hyperacuity, modal assumptions: A review.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Vernier thresholds rise much more rapidly in the periphery than do grating thresholds. A similar dissociation between acuity and hyperacuity has been shown to be present in strabismic but not in anisometropic amblyopia, thus leading to the suggestion that the strabismic fovea is similar to the normal periphery. Here it is shown that a quantitative model for spatial pattern discrimination, which accounts for foveal hyperacuity data, can be extended to encompass both the periphery and amblyopia if appropriate alterations are made. For the periphery it is necessary to increase the size of model receptive fields and to int...

Rotational stability of femoral osteosynthesis in femoral fractures - navigated measurements.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Rotational malalignment after intramedullary nailing of femoral fractures is common, and symptoms occur when malrotation reaches 15 degrees . Intraoperative measurement of rotation remains difficult, and multiple techniques have been described to address this. Regardless of the method used, rotational toggling may occur between the interlocking screws and the screw holes. We hypothesized that a clinically significant amount of rotation may occur with standard statically locked intramedullary nails. Mid-shaft diaphyseal fractures were created in 24 cadaveric femurs. Specimens were divided into 4 groups, and were stabili...

Evidence for the role of osteocytes in the initiation of targeted remodeling.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Microdamage in bone contributes to fractures and acts as a stimulus for bone remodeling. Osteocytes are the most abundant cells in bone, and their death by microdamage has been suggested to be the major event leading in the initiation of osteoclastic bone resorption. Even though there is increasing evidence that osteocyte density, microcracks and targeted remodeling are related, there still exist several questions. For example, how osteoclasts are targeted to the specific site of microdamage for repair. It has been proposed that apoptotic osteocytes could secrete a specific signal to target osteoclasts. The other quest...

Stochastic resonance is exhibited by many biological systems, where the response to a small stimulus is enhanced with the aid of noise. This intriguing possibility provides a novel paradigm for understanding previously reported osteogenic benefits of low amplitude dynamic loading. However, it is unknown whether bone cell mechanosensitivity is enhanced by noise as an alternative mechanism for an amplified response to small stresses. We studied whether noise of varying intensities enhanced the mechanosensitivity of MC3T3-E1 cells. Nitric oxide (NO) production was measured as the parameter for bone cell activation. Dynami...

Microdamage detection and repair in bone: fracture mechanics, histology, cell biology.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Bone is an elementary component in the human skeleton. It protects vital organs, regulates calcium levels and allows mobility. As a result of daily activities, bones are cyclically strained causing microdamage. This damage, in the form of numerous microcracks, can cause bones to fracture and therefore poses a threat to mechanical integrity. Bone is able to repair the microcracks through a process called remodelling which is tightly regulated by bone forming and resorbing cells. However, the manner by which microcracks are detected, and repair initiated, has not been elucidated until now. Here we show that microcrack ac...

Simulation of stress urinary incontinence for in-vitro studies.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A simulation system that generates dynamic bladder pressures for the use of testing and examining artificial urinary sphincters is designed, implemented, and compared to in-vivo measurements of Valsalva and coughing profiles. Cylinder and piston, which are integrated into the universal testing machine, simulating the bladder are connected with explanted sow urethras. The AMS 800trade mark artificial urinary sphincter closes the urethra with well-defined external pressures. In order to select appropriate profiles for the bladder pressure, 34 Valsalva and coughing profiles of 6 patients were evaluated with respect to amp...

The effect of tourniquet release timing on perioperative blood loss in simultaneous bilateral cemented total knee arthroplasty: A prospective randomized study.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this study we found no significant difference in perioperative blood loss and no increase of postoperative complications. Therefore, we recommend a tourniquet release after wound closure to reduce the duration of TKA procedure and to avoid possible risks of extended anaesthesia.

Influence of fibrin glue on proliferation and differentiation of human bone marrow stromal cells seeded on a biologic 3-dimensional matrix.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study analysed the effect of fibrin glue on bone marrow stromal cells (BMSC) adhesion, proliferation (MTS-Test), differentiation (alkaline phosphatase (AP), osteocalcin (OC), ELISA) and compared the results with cells seeded within culture media on a decellularized, xenogenic bone matrix. There was no significant difference regarding cell adhesion. Proliferation after one week was significantly increased without fibrin glue. AP was increased in both groups when compared with porous scaffolds without cells. OC secretion was increased under both seeding conditions. Microscopic investigation of the cells with fibrin-glue...

An international assessment of a web-based diagnostic tool in critically ill children.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Improving diagnostic accuracy is essential. The extent of diagnostic uncertainty at patient admission is not well described in critically ill children. Therefore, we studied the extent that pediatric trainee diagnostic performance could be improved with the aid of a computerized diagnostic tool. Data regarding patient admissions to five Pediatric Intensive Care Units were collected. Information included patients' clinical details, admitting team's diagnostic workup and discharge diagnosis. An attending physician assessed each case independently and suggested additional diagnostic possibilities. Diagnostic accuracy was ...
