Developing affordable technology that supports comprehensive self-management of HIV poses great challenges as it has to address complex care needs including prevention of risky behavior, slowing of disease progression and medication adherence for antiretrovirals, opportunistic infection medication and possibly other chronic disease medication. The combination of multiple health communication channels...
Osteoarthritis (OA) is commonly seen among older populace and it is the most widespread of arthritic type. It is a degenerative joint disease where cartilage slowly wears away. Cartilage that covers the bone ensures the smooth movements of the joints. In knee OA, affected bones slide together due to degradation of cartilage, causing swell, pain and eventual loss of motion. Due to stress, knee joints...
Upper limb rehabilitation concentrates on restoring the operations of arms, hands and fingers. This integrated measuring device is in the form of a glove which records the force exerted for fine motor activities and hence indicates to the physiotherapist who guides the patient to regulate the force as per the need and thus avoid applying unwanted strain. Though this device has not yet been fabricated...
In this paper, we discuss a wearable wireless system capable of acquiring data from a variety of sensors. The device uses Bluetooth technology to stream data from up to 16 channels/sensors to a laptop computer running MATLAB. Complete with programmable sampling rates, off-the-shelf components, and power saving features, this system provides an inexpensive and reliable means of transmitting data for...
The most important determinant of prognosis and management of cancer is the presence or absence of metastasis [1]. The road to metastasis involves tumor cells to become detached from the primary tumor and travel in the blood to distant sites, causing secondary tumors. These tumor cells traveling in blood are termed Circulating tumor cells (CTC). Capture of CTC from whole blood has been a challenging...
Acne scars are of great cosmetic concern, and there are several methods of treatment towards reducing the appearance of scars. Automatic detection of acne scar-pixels from digital color images would be helpful in quantitative assessment of the success of treatment. This paper addresses detection of acne scar-pixels based on color image processing. The RGB model is used to representing the data. Pixels...
This paper describes the use of Bayesian Information Criteria (BIC) along with some standard feature extraction methods and Linear Discriminant Analysis (LDA) classification algorithm to separate 8 different phases of gait by using electromyographic (EMG) signal data of the lower limb. Four time domain features along with 4th order Auto-Regressive model were used to get feature vector set from the...
Studies showed that obtaining personalized health information facilitates patient education and compliance. Older adults with various comorbidities and their caregivers could potentially benefit from obtaining personalized health information via a web-based patient portal. However, it is not clear whether this population, that could potentially most benefit from a patient portal, is likely to make...
Geriatric rehabilitation facilitates therapeutic interventions whose purpose is to restore functional ability or enhance residual functional capability in elderly people with disabling impairments. Despite great demand for such interventions, limited research has been conducted in utilizing telemedicine to promote geriatric rehabilitation. Previously we reported successful implementation of physical...
Neonatal spells are cardiorespiratory events that occur in newborn infants with variable combinations of cessation of breathing, decrease in blood oxygen saturation and decrease in heart rate. A system using real-time temporal analysis of physiological data streams to accurately detect pauses in breathing together with changes in heart rate and blood oxygen saturation is described. The system uses...
Public health surveillance is the ongoing systematic collection, analysis and interpretation of health-related data. It serves as an early warning system for impending public health emergencies. This paper presents an efficient framework for automated acquisition and storage of medical data using the infrastructure provided by Short Message Service (SMS). The data to be collected are dynamically organized...
An implementation of neonatal cry classification on an embedded platform is presented in this paper. It was perceived that diagnosis of the cause of human baby cry can be aided with an electronic device which can help parents and doctors comfort their baby. The present work gives detail of such a mobile device which runs on Android operating system and includes an Android application for neonatal...
Listening to the heart sounds is a common practice in identifying cardiac malfunctions. Since this method has many limitations, tools that aid physicians in their diagnosis of heart diseases are very useful. This paper presents a software tool to predict cardiac abnormalities which can be identified using heart sounds. Both heart sound information and symptoms are used in disease prediction. First...
Many advantages of microwave ablation over the other ablative therapies in the field of liver tumor ablation have driven researchers to develop innovative interstitial microwave antennas to effectively treat deep seated, nonresectable hepatic tumors. A new coaxial antenna for microwave ablation therapies has been proposed in this research paper. Two dimensional axisymmetric Finite Element Method (FEM)...
Way-finding Electronic Bracelet (WEB) for visually impaired (subject) is a portable embedded system for obstacle detection and way-finding. This MSP430G2553 processor based real-time system employs single Maxbotix MB1340 ultrasonic transceiver mounted on customized circular bracelet for detecting obstacle in the range 20 to 600 centimetres. Half duplex wireless communication is used for invoking vibrotactile...
A novel data-mining method was developed to gauge the experiences of medical devices and drugs by patients with diabetes mellitus. Self-organizing maps were used to analyze forum posts numerically to better understand user opinion of medical devices and drugs. The end-result is a word list compilation that correlates certain positive and negative word cluster groups with medical drugs and devices...
Photoplethysmography (PPG) is a non-invasive optical technique used in detecting blood volume changes in vascular tissue. In recent years, photoplethysmography has generated renewed interest among researchers, particularly due to its potential for widespread clinical applications beyond estimating heart rate and arterial oxygen saturation. Progress in these areas of research is dependent on PPG systems...
TB and Lung cancer are major ailments of the lung. Patients with lung cancer are often misdiagnosed as pulmonary tuberculosis leading to delay in the correct diagnosis as well as exposure to inappropriate medication. The diagnosis of tuberculosis and lung cancer is difficult, as symptoms of both diseases are similar. Due to high TB prevalence and radiological similarities, a large number of lung cancer...
This paper describes our experience in designing a clinical trial protocol and its registration in Clinical Trials Registry- India (CTRI). The aim of our trial is to assess efficacy of a newly developed indigenous, low cost functional electrical stimulator (FES) device for correcting foot drop in stroke survivors. We started with shortlisting the existing trials from the search result of different...
This paper describes a prototype model for cardiovascular activity and fitness monitoring system based on IEEE 11073 family of standard for medical device communication. It identifies basic requirements for developing a biomedical sensor network having resource limited sensor nodes to acquire, retrieve and communicate various physiological parameters while using short range wireless technologies....
