Diabetes is an autoimmune disease in which the pancreas no longer produces insulin needed in order to maintain proper blood glucose levels. Managing diabetes requires consistent monitoring of blood glucose levels as well as administering insulin. At times, these tasks may become tiring and patients often to do not fully comply with the recording and treatment instructions given to them from their...
GE Healthcare is currently designing a system to simplify and automate the scanning process of rheumatoid arthritis (RA) progression in the hand. In accomplishing this goal, a hand supporter is being designed that allows the patient to rest their hand comfortably despite mild RA deformities while achieving the best possible image quality. The purpose of the team's design is to implement the automated...
It was found that the material properties of the human spleen were not strain rate dependent within the tested range. This finding can lead to simplified models with elastic material properties that can quickly determine the effect of loading on the spleen including prediction of failure.
Women who have a high-risk of preterm labor would benefit from a device that continuously-monitors their cervical dilation. The proposed methodology for such a device consists of an internal device that measures the woman's cervical dilation and wirelessly transmits these measurements to an external device as well as her physician. When critical dilation is detected, the woman will be prompted to...
Motion based gaming was used in combination with standard therapy in 17 mild traumatic brain injury participants when compared to 20 controls to study the effectiveness of motion based gaming on physical activity level and postural stability measured by using body worn sensors. Significant improvements in number of steps, stability, and perceived motivation suggest promising use of motion based gaming...
This system aims to provide force and muscle activation information to assess the biomechanical performance of cane handles using data from gait trials performed by a patient. This device can be used to improve individual prescription of canes or help guide research for the design of more effective and less damaging cane handles.
Intra-arterial chemotherapy delivery (IAC) for treating cancer can lead to significant cardiac toxicity due to the drainage of excess drug to the systemic circulation. A catheter-based Chemofilter device temporarily inserted into the veins downstream of the tumor can remove chemotherapy drugs out of the blood stream right after these drugs have had their effect on the tumor. In this research, computational...
A novel method for direct estimation of axial, lateral and shear strains in tissue using high frame rate ultrasound images is developed. Conventionally, strains are calculated from the spatial derivatives of displacements in different directions, which would result noise amplification and therefore low accuracy of the estimation. The new method uses the local properties of autocorrelation functions...
The finite element model developed was able to capture the effects of loading rate and geometry. It was found that the predicted equivalent stresses of the human spleen subject to blast loads decreased with increasing load rate, even though viscous effects were found to be negligible. Therefore, the strain or loading rate (dynamic effects) must be correctly modeled, and reported so as to allow for...
Current smartphone camera can capture high-definition (HD) video. It is hard to process a lot of video frames for a conventional personal computer due to the high-resolution image. High configured computer can extract the color pixel information from this type of video image, though it takes unreasonable time. For this reason, we proposed a novel way to record the image pixel information in a histogram...
Advanced robotic technology has become a significant component in many medical specialties, including in rehabilitation tasks such as physiotherapy. Rehabilitation programs are a practical approach created to assist patients, such as stroke victims, in retrieving their missing functional capacity, obtaining new skills, and enhancing their quality of life. Nevertheless, rehabilitation treatments need...
Digital healthcare can be provided in various means. One potential means is playing exergames that combine exercise into computer gaming applications. We investigated whether playing exergames induces positive moods that are known positive to health. We consulted the methodological literature to design a rigorous experiment, including blinding to nearly all research assistants. We assigned the subjects...
Stoke is the second of causes of deaths on the earth and the third of the top ten in Taiwan. About 70% of stoke patients can restore walking ability through rehabilitation, and 50% of stoke patients can live with daily life. In this paper, we designed and evaluated a user-centered stroke rehabilitation games. We used Information Systems Research (ISR) framework as guideline which Schnall et al. proposed,...
EEG PSD is often used as a measure of cognitive function and emotional state while MI is a reflection of functional connectivity in the brain. Analysis of both quantities in a child with severe disabilities suggests that PMT may be associated with an increase in cognitive performance, as well as connectivity between the frontal and parietal lobes.
A parallel dielectrophoretic single particle trap lab-on-a-chip system has been constructed and utilized to characterize the physical, electrical, and biological properties of single particle. We show proof-of-concept for the array of dielectrophoretic single particle trap that captures individual micro-/nano-particles in each trap.
