We suggest the optimal position of sensors used for measuring foot pressure. Foot pressures were obtained from 11 healthy persons (6 men and 5 women) while they were walking on a treadmill for 1 minute at 3km/h. The order of high correlation coefficients were in: the heel region (r = −0.35 on sensor number 10), the metatarsal region (r = −0.27 on sensor number 79), the toe region (r = −0.19 on sensor...
We have been unwittingly exposed to magnetic field. Biological effects due to electromagnetic field exposure has been studied over the past several decades. There has been epidemiological studies and laboratory studies. In the case of laboratory studies, the effect was observed through the cell stimulation of an artificial magnetic field. The used frequency and waveform are various in the cell experiment,...
Considering the vast variety of EMG signal applications such as rehabilitation of people suffering from some mobility limitations, scientists have done much research on EMG control system. In this regard, feature extraction of EMG signal has been highly valued as a significant technique to extract the desired information of EMG signal and remove unnecessary parts. This proposed method is based on...
This paper presents a method for a contact-free heart rate measurement on a video sequence using Simulink. The heart rate is measured by detecting the prominent frequency of the skin-color change in a human face. As color features in a video sequence, we utilize both green and hue signals. The frequencies of the two color signals are analyzed using multiple observing times. The prominences of the...
Respiratory is known to be a confounding factor of Heart Rate Variability (HRV) analysis. This article introduces a Breath-to-Breath Interval (BBI) spectral computation to investigate the insight between respiration and the HRV. Six males and five female volunteers (age 20–25 years) underwent the Electrocardiogram (ECG) and respiratory chest movement recordings for 5 minutes while sitting in resting...
The objective of this work is develop the paradigm for training subject with dyslexia. Leap motion sensor used to develop the training program for subject's evaluation. This paper studies about fingers position data interpolation from Leap motion sensor. The fingers data used to control the visual hands to play a piano. Linear interpolation of Leap motion data show the signal smoothing than original...
The prosthesis is the device which replace the missing part or structure, can be inside or outside the human body. The prosthetic alignment is the method to find the optimal prosthetic function and a very important for efficiency and effectiveness delivery of the prostheses. Good alignment can reflex the better of gait pattern, more natural of gait cycle and less energy consumption during locomotion...
The ECG analysis program can provide much information about cardiac disorder. Comparison with visual analysis, require specialist which are not available in many occasion. Therefore, computer-based technique that develops for ECG analysis can used to training inexperience staff and prediagnostic the ECG data. In this work, the ECG analyzing algorithm for arrhythmia detection was applied using MATLAB...
the fluctuation of received signal strength indicator emerges poor accuracy in healthcare location monitoring service. To enhance the capability of position classification, this paper represents positioning system based on ZigBee standard using artificial neural networks algorithm. Time-delay Multi-Layer Perceptron is proposed by using Levenberg-Marquardt optimization. For the result, the average...
A promising acetylcholine biosensor based on graphene-PEDOT:PSS (GR-PEDOT:PSS) and bienzyme, choline oxidase (ChOx) and acetylcholine esterase (AChE), modified electrode was successfully fabricated. GR-PEDOT:PSS ink was directly dropped on the screen printed carbon electrode (SPE), and then ChOx and AChE in the optimized loading ratio were immobilized on GR-PEDOT:PSS/SPE by the 10% glutar-aldehyde...
There were two objectives of this paper. The first objective of this paper was to observe the brain activity of Asian athletes before the match. Second, the paper aimed to study the anxiety symptom showing on the brain via QEEG (Quantitative Electroencephalography) maps. The anxiety level for Asian athletes can be classified using the index of brain topographic map (Absolute power) relative to the...
The difficulty to understand meditation is the lack of exact methodology, replication of mind condition and depends on individual meditative practice. From these reasons, this research focuses on a relationship between meditation and EEG. The Quantitative EEG will be analyzed and observed in absolute power of each EEG rhythm. Coherence was also analyzed after participants practice meditation during...
Stroke is widely common cause of death and disability in adult. It is occurred when the blood supply in the brain is ruptured or blocked. Post stroke rehabilitation is the most important for stroke survivors because it assists them to restore their physical function such as arm movement, walking and daily life activity. Neuro-rehabilitation can enhance neuron pathways and improve motor function of...
This research proposes a design of a novel microwave applicator which encapsulated in fluid reservoir for a thermal therapy. Heat generated from microwave energy is applied to cure or to reshape a hollow-tubing shape organ or misshape organ from occlusion or narrowing such as tracheal and benign prostatic hyperplasia. This promising technique provides a shorter treatment time and minimal invasive...
Microwave ablation has several medical applications including liver, kidney, bone and lung. Numerical simulation of microwave ablation is a step in the implementation of system design. This paper presents the temperature distribution of targeted radiation dipole antenna for microwave ablation at 2.45GHz. This experiment through the temperature profile around the antenna achieves in the range 50W,...
Parkinson's disease is one of movement disorder that affected to quality of life. The exercise training can improve movement of patients. The aim of this study was to investigate the effect of bicycle riding to the brain activity by observing the absolute power and coherence revealed by the quantitative electroencephalogram (QEEG). The participants consisted of four healthy individuals. Each participant...
We have an interest in the forward kinematic solution of a three-DOF cable-driven parallel end effecter for rehabilitation of the upper limbs. Although to solve the forward kinematic solution is to decide the position and orientation of end effecter by using four given cable lengths, it is well known that it is difficult to make sure the only solution among multiple solutions of cable-driven parallel...
Pain is unpleasant sensory which is always a subjective measurement. Various studies try to find a solution to have life without pain. In critical situation, the treatment of burn patients need some criteria to understand a level of pain sensation. This study focuses on an acute thermal pain. The purpose of this study is to block the pain pathway using the transcutaneous electrical nerve stimulation...
In this simulation, the cardiovascular model was developed base on the physiological study. The parameter identification and validation was done with physiological data using Matlab/Simulink. This study has adopted the principle differential equation using analog-lump parameter model. The wave forms such as pressure, volume and flow in cardiovascular system were simulated. The simulation of cardiovascular...
