Background Adults with sedentary lifestyles seem to face a higher risk of falling in their later years. Several causes, such as impairment of strength, coordination, and cognitive function, influence worsening health conditions, including balancing ability. Many modalities can be applied to improve the balance function and prevent falling. Several studies have also recorded the effects of balance...
Rehabilitation is very important for patients who suffer from stroke or spinal cord injury. To restore musculature, it is necessary to prepare for the next step of therapeutics. The passive exercise is one of the method to maintain the musculature and prevent complication as deep vein thrombosis (DVT) as the patient cannot move leg until patient has been recovered. After that active exercise can be...
To achieve the sufficient treatment, the rehabilitation is a main key to regenerate the hand performance. Due to one occupational therapist can rehabilitate one patient at a time and the number of patients is increasing, this causes occupational therapist overload. HEXO is a device for passive support of the joint movement by controlling through the software. It performs on four fingers which are...
Telerehabilitation is a new technology, which connects the patients and physicians or therapists via internet. This paper represents the systems that proposed for the combination of diagnostic devices and Telemedical system, including plantar pressure measuring devices that use during rehabilitation process. The parameters, determined by the devices, can be sent automatically from patient's computer...
Center of pressure (COP) movement during sitting on an unstable chair can be used to represent static trunk postural control. Theoretically, healthy individuals with intact trunk proprioception should have similar COP movement between eye-open and eye-closed conditions regardless of visual feedback. The custom software program has been developed to investigate COP movement in this group of participants...
Early stage of chondromalacia patella is usually asymptomatic. Detection of chondromalacia patella sooner can delay further cartilage degeneration by appropriate exercise prescription and behavioral change. The purpose of this study is to preliminary examine asymptomatic subjects and investigate the knee vibroarthrographic (VAG) signals in order to suggest possible parameters to detect chondromalacia...
Postural stability is a necessary activity for human livings. To understand this behavioral function can perform by using instruments or clinical assessments. Motion analysis is a famous method to analyze the motion pattern in healthy people or patients with dysfunctional movement which provide information in 3-dimension. To analyze the information can acquire from various methods and must compute...
Neurological patients, such a stroke or spinal cord injury, require the rehabilitation treatment in order to return back to the daily livings. To retain the musculature quantity and quality, the passive exercise can be an option which can be done by either the physical therapist or the robot assisted. LeHab robot is designed with three degree of freedoms. The robot consists of three links and three...
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...
Many people have lower limb paralysis from different reasons and many Thai patients were prescribed by passive orthoses although some active orthoses have been invented [1–5] for more natural and smooth gait because of augmentation and control of weak motions for the paralyze people, but the price is expensive and difficult for Thai disables to access. The objective of this study is to develop the...
At present, patients whose have suffered from stroke in Thailand are increasing every year. Stroke impairments relate to many functions such as sensory, motor function, communication, visual and emotional function which depend on brain's lesion. Physical examinations and assessments are important for planning the rehabilitation programs. For this reason, there are several information for medical decision...
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...
Body balance and center of pressure (COP) of the human body are extensively studied to assist the patients who loss of the body balances. Many medical devices are developed to detect the human body imbalance and to measure COP. This research presents a new medical device to measure the plantar pressure distribution. The device is capable to monitor the physical body balance, to identify the pathomechanical...
Human postural stability is the necessary function for human livings. This function controls the whole body into the upright position. To understand the behavior of human balance control can be achieved by many methods. The mathematical model is a general technique for explanation the mechanism of biomechanics. The human postural stability system has been designed into the mathematical model. The...
Virtual reality technology is common used to entertain people as movies or games. At present, this technology applies to medical field for training surgeon on operating simulation or patients with either neurological disease or psychiatric disorder. The study focused on the algorithm of pattern classification. The artificial neural network was considered to achieve this classification. The multilayer...
For trans-femoral (TF) amputee, the prosthetic knee component performs important roles to assist the motion of prosthetic leg during gait. Even though the variety prosthetic knee component can perform variety functions, the stair ascending gait still be the challenge mode of gait for TF amputee as the unexpected environmental had to be faced daily. This study is aiming to establish the design of the...
This paper studies about electromyography (EMG) classification. The application of EMG classifier is used for prosthetic control. A Volterra series was propose in this works, we used 2nd order series for processing EMG signal. This work had compared between filtered EMG and 2nd Volterra EMG in artificial neural network (ANN) model. The result show the classification with 2nd Volterra EMG has more...
Walking up or down stairs is an important activity for human lives. Gait pattern of this activity is as same as walking except the range of motion and phase of muscles activities. Many studies have been focused on behavior of this motion. Two cameras and electromyogram (EMG) are the applications used in this study and analysis the motion. To determine the relationship of the both data, it can be performed...
This paper studies the application of the non-linear model (ANN, ANFIS). ANN and ANFIS were used to fit a Blood-Oxygen Level Dependent (BOLD) signal with design architecture. A model proposes to define region of interest (ROI) in brain fMRI images. The result shows the ANFIS model can be represent to fit the BOLD data better than ANN. Three paradigms were stimulated at difference issue activation...
For the Trans-femoral (TF) amputee, the biomechanics of stair gait can be analyzed in only the stair descending. The information of stair ascending gait can be evaluated for only the normal side. The study with TF amputee mostly referred to the stair ascending by leading with the normal side rather than the prosthetic side as there was none of prosthesis can be the leading side to climb up the stair...
