The purpose of this system is to establish virtual medical school (VMS) as the platform of e-learning center, which integrates collaborative and self-directed learning environment by virtual group, classroom and library, and automatically converts valuable clinical case from Hospital Information System (HIS) database into virtual patient by online authoring tools for problem-based e-learning. In this system, the VMS provides a problem-based e-learning environment, and utilizes HIS to capture and store valuable clinical cases. All medical students and residents now have the opportunity to learn from these typical cases online. The VMS at National Taiwan University has the potential to develop into a national medical education network for the meditation and provision of comprehensive medical resources. The system will use the international standard SCORM 1.2 to develop teaching material and assist with the HL7 v2.4, CDA v1.0 standards to connect Electronic Medical Record (EMR) systems in the hospital. It can provide resources sharing among medical centers by using high transportation ability of Grid Computing integrated with the broadband video platform, Access Grid, and personal multiple point videoconference platform, Multi-video, to popularize the application of e-learning in clinical medical education.

Background and Purpose: Sonophoresis is a noninvasive ultrasound-based method for the transdermal delivery of drugs. However, the importance of the thermal effects in sonophoresis via therapeutic ultrasound remained unclear. In this study, an animal study was used to evaluate the contribution of thermal effects in 1MHz ultrasound mediated transdermal drug delivery. Method: Rats in the ultrasound-treatment, heat-treatment, and control groups received ultrasound treatments (1MHz, 2W/cm^2, 100% duty cycle, 5 min), heat treatment (tail in 50℃ water-bath for 10 min), and no treatment, respectively, before applying eutectic mixture of local anesthetics (EMLA) cream. Sensory conduction in the tail nerve was investigated before and every 5 min after treatment for 60 min. Results: There was no significant difference between the control and heat-treatment groups in the latency to the reduction in sensory nerve conduction velocity (SNCV) or in the sensory nerve action potential (SNAP) amplitude. The latency for the SNCV to decrease by 20% was significantly lower in the ultrasound-treatment group than in the control and thermal-treatment groups. Compared with control group and thermal treatment group, using ultrasound could reduce the latency for an EMLA reaction from 60 min to less than 20 min. Conclusion: In this study, the thermal effect seemed less important than the mechanical effects in sonophoresis via therapeutic ultrasound.

Owing to the increasing number of disabled individuals, technical aids are acting more aggressively in the era of modern medicine. The M3S (Multiple Master Multiple Slave) system developed for the physically challenged, utilizes intelligent transmission and integration mechanisms to arrange all hooked-up devices with proper control. To overcome certain limitations of the system (e.g. distance), an RF (Radio Frequency) wireless module would be in charge of the wireless communication between a remote bus and a local bus. It is demonstrated here as assistance for parking assistive vehicles (e.g. powered wheelchair) located in a remote region, which also includes monitoring and usage of accessorial data transmissions shown in our man-machine interface.

This article describes a low-cost, portable real-time DSP-based speech controller system to provide radio interface control command applications for the blind. The system recognizes spoken Mandarin Chinese words on a DSP chip (TMS320C31) using a hidden Markov model. The function of the radio set, which includes a tuner, tape, and compact disc, were evaluated under both noisy and noiseless environments. Four subjects took part in the experiment and achieved 83 and 90% mean recognition rates under noisy and noiseless conditions, respectively. In addition, because this system is based on a DSP chip, it can easily be programmed to execute speaker-independent algorithms.

BACKGROUND: Recent advances in technology have warranted the use of wearable sensors to monitor gait and posture. However, the psychometric properties of using wearable devices to measure gait-related outcomes have not been fully established in patients with Parkinson’s disease (PD). OBJECTIVE: This study aimed to investigate the test-retest reliability of body-worn sensors for gait evaluation in people with PD. Additionally, the influence of disease severity on the reliability was determined. METHODS: Twenty individuals with PD were recruited. During the first evaluation, the participants wore inertial sensors on their shoes and walked along a walkway thrice at their comfortable walking speed. The participants were then required to return to the lab after 3–5 days to complete the second evaluation with the same study procedure. Test-retest reliability of gait-related outcomes were calculated. To determine whether the results would be affected by disease severity, reliability was re-calculated by subdividing the participants into early and mid-advanced stages of the disease. RESULTS: The results showed moderate to good reliability (ICC = 0.64–0.87) of the wearable sensors for gait assessment in the general population with PD. Subgroup analysis showed that the reliability was higher among patients at early stages (ICC = 0.71–0.97) compared to those at mid-advanced stages (ICC = 0.65–0.81) of PD. CONCLUSIONS: Wearable sensors could reliably measure gait parameters in people with PD, and the reliability was higher among individuals at early stages of the disease compared to those at mid-advanced stages. Absolute reliability values were calculated to act as references for future studies.

Healthcare services integration is a critical task as it attempts to reform the user practices. In response to the request of facilities upgrade, we perform a usability evaluation of the mobile medical treatment carts (MMTC) installed in the Emergency Medicine Department of our healthcare enterprise. A survey conducted in August 2006 identified that our experimental area needs some improvements to support the MMTC adoption. For example, the MMTC can accompany with several popular nursing care items. Follow-up several undertaken investigations indicated that our expectation of the MMTC solution had been reached. Given the evident heterogeneity of viewpoints, it is imperative for a healthcare enterprise to broadly ascertain the requirements of end users before investing in any information technologies.

To improve the operating speed of the traditional row-column scanning computer keyboard-mouse composite panel controlled using a single key. Using a single mouse input control window can avoid scanning unnecessary keyboard characters, thereby increasing the speed in performing mouse commands. In addition, the surface electromyographic (SEMG) sensing input can also be used to provide an input option for the disabled. Eleven volunteers operated the single mouse input control window using the SEMG input and the traditional computer keyboard-mouse composite panel controlled using a single key. The average operating times were 121.3+/-8.9 sec and 208.6+/-10.7 sec, respectively. The difference was statistically significant (p<0.05). The row-column scanning method with the single mouse control window using SEMG input can effectively decrease the operating time. Through this system, the disabled can operate a computer and lead an independent life.

ABSTRACT Exercise dosage is proven to be an important factor in the physical treatment. Robot assistive approach can improve the rehabilitation quality and evaluate patient's recovery quantitatively. This paper presents kinematic structure, assistive control system, and integrated F/T sensor for an upper limb rehabilitation robot. By using the human arm dynamic, there are three rehabilitation modes presented in this paper: active mode, assistive mode, and passive mode. In assistive mode, we have two strategies to implement it. One is to amplify interactive torque, and the other is to apply assist-as-needed concept. The goal of this mode is to assist patients to finish motion tasks. The rehabilitation robot under investigation has 7 degree of freedom (DOF) actuated by DC motors, which are programmed to drive the robot arm in the 3D space. To validate our control design, some realistic experiments are conducted and its satisfactory performance is demonstrated. This work is approved clinical testing by the Department of Health, Executive Yuan, R.O.C. So far, we are demonstrating the effect of our controller.

This paper proposes the development of a surface electromyographic (SEMG)-controlled telephone interface for the disabled. The system is composed of three major components: (1) a SEMG receiving/signal-processing module; (2) a row-column scanning interface for the telephone dialling pad; and (3) a main controller, the Intel-8951 microprocessor. The design concept was based on the idea of using a SEMG generated by the disabled and converting it into a trigger pulse. This could allow convenient control of the dialing motion in the row-column scanning keys of a telephone dialling pad. People with disabilities are competent for certain kinds of work such as being a telephone operator. The increase of opportunities to perform a job for the disabled would help them live independently.

The current study examined the effects of applying relaxation breathing training (RBT) as a means to reduce music performance anxiety (MPA) in young, talented musicians. A group of 59 young musicians from 3rd to 6th grade participated in this study, and all of them started RBT twice a week for 2 months prior to the examination. Four tests--2 mos, 1 mos, half an hour and 5 min before the examination--were conducted to examine the level of MPA after the application of RBT. Results show that the degree of MPA 5 min before the trial was lower than the degree of performance anxiety half an hour before the jury (t = -3.683, p < 0.01), which indicated that the RBT was associated with a decrease in MPA. Although a series of RBT exercises was applied, results indicated that when approaching the date of examination, the degree of performance anxiety still increased and reached its maximum half an hour before the jury. The recommendation for future studies is to combine the application of RBT with other methods to expand its effect in reducing MPA.

A healthcare pattern collection for the rural telemedicine services contains a union telemedicine clinic center, an integrated telemedicine healthcare equipment and an electronic health record (EHR) system were implemented in National Taiwan University Hospital. The healthcare registration patterns integrate the telemedicine center to enhance the acceptability of the healthcare services for the hilly region and redeem the lack of medicine man power in such area. Meanwhile, the derived patterns utilize the healthcare equipment to integrate the required information and EHR to process the clinical reports. The patterns serve a better-factored design. Many recurring patterns are identified to describe the design of the telemedicine services in this study.

Background and Purpose: Rehabilitation is recommended to start as early as possible after stroke onset. In the intensive care unit (ICU) of our facility, patients are generally prescribed bed rest within 3 days after stroke to reduce neurological complications. Additionally, the patients in stroke ICU may not have sufficient endurance, such as attention or alertness, for standard rehabilitation treatment. One potential rehabilitation approach for facilitation in stroke patients staying in ICU is electrical stimulation, such as transcutaneous nerve stimulation (TENS) and functional electrical stimulation (FES). Although some investigators have studied the benefits of FES in the early phase of recovery after stroke, limited studies have investigated the effects of TENS for motor recovery in stroke patients staying in stroke ICU. This study aims to investigate if TENS has similar effect on motor recovery as those who received FES. Methods: Forty-five stroke patients who were admitted in stroke ICU within 3 days after stroke onset were randomly allocated to standard rehabilitation (SR) group (n = 19), FES group (n = 13) and TENS group (n = 13). For the FES and TENS group, the interventions were applied at the tibialis anterior and quadriceps muscles over the paretic side for 30 min additional to standard rehabilitation. The measurements included whether the participants achieve three mobility milestones, which are sitting ≥ 5 mins, standing ≥ 1 min, and walking ≥ 50 m, within 14 days after stroke. We also measured the postural assessment scale for stroke patients (PASS) scores at the 2nd and 4th post-stroke weeks. Outcome measurements were analyzed with repeated measure analysis of variance and a χ2 test. Results: The rate of achieving the milestone of walking ≥ 50 m within 14 days after stroke in the FES and TENS groups were significantly higher than the SR group. The FES and TENS groups demonstrated significantly greater increase in the PASS scores at the 2nd post-stroke week than the SR group, but no significant differences were found between the FES and TENS groups. Conclusion and Clinical Relevance: Applying either TENS or FES on the paretic lower limb in stroke ICU improves the mobility and postural control in the acute stage. TENS and FES show similar effects on motor recovery in the acute phase.

Cerebral vascular disease (or stroke) is the main cause of disabilities in adults. Upper-limb dysfunction after stroke usually exists, leading to severe limits of motor capabilities as well as daily activities. Therefore, effective treatment interventions for upper-limb rehabilitation after stroke are needed. Based on the neurophysiological evidence and clinical measures, combined bilateral arm training (BAT) with functional electric stimulation (FES) could improve hand function in stroke patients. In this study, we attempt to combine BAT with FES applying to the post-stroke paretic arm. A linear guide platform with FES feedback control was developed to execute the training of bilateral reaching movements. 35 stroke subjects were recruited and divided into two groups (BAT with FES and BAT alone). 23 participants completed this experiment with 3-week intervention. According to our preliminary results, a favorable trend toward improvement in experimental group (BAT with FES) existed after treatment and at follow-up. Further analysis would be conducted to investigate the kinematic change on motor performance. Moreover, various treatment doses as well as more functional approaches would also be considered for better effects of upper limb rehabilitation after stroke.

The M3S (Multiple Master Multiple Slave) is an intelligent transmission system for the disabled. This integrated system combines technical aids for mobility, manipulation, environment control and communication. However, signals must be transmitted by a RF (Radio Frequency) module to overcome critical limitations of the CAN Bus (e.g. length). Appliances in different rooms are attached to different "remote" M3S Busses, while the user's "local" M3S Bus controls these remote links by manipulating all output devices on the remote end with input devices on the local end. Signals may also be transferred singly through remote M3S Busses, allowing the neighborhood remote Busses to interface between origin and destination.

Background People with Parkinson’s disease (PD) are known to have motor learning difficulties. Although numerous studies have demonstrated that a single bout of aerobic exercise (AEX) can facilitate motor learning in non-disabled adults, the same beneficial effect in PD is unknown. Furthermore, associated neuroplastic changes have not been investigated. Objectives This study aimed to determine whether a single bout of aerobic exercise (AEX) can facilitate motor sequence learning in people with PD and to investigate the associated neurophysiological changes. Methods Thirty individuals with PD were recruited and randomized into the exercise group (PD + AEX) and non-exercise group (PD − AEX). At the first visit, corticomotor excitability was assessed using transcranial magnetic stimulation (TMS). All participants then performed a serial reaction time task (SRTT) followed by 20 minutes of moderately-high intensity aerobic exercise (AEX) for the PD + AEX group or rest for the PD − AEX group. The SRTT and TMS were reevaluated at 3 time points: immediately after aerobic exercise (AEX) or rest, on the second day after practice (D2), and a week after practice (D7). Results Both groups showed improvement throughout practice. At retention, the PD + AEX group showed improved SRTT performance on D7 compared to D2 ( P = .001), while the PD − AEX group showed no change in performance. TMS results showed that the PD + AEX group had significantly higher corticomotor excitability than the PD − AEX group on D7. Conclusion A single session of aerobic exercise (AEX) could enhance motor sequence learning and induce neuroplastic changes. Clinicians can consider providing aerobic exercise (AEX) after motor task training for people with PD. Clinical registration: NCT04189887 (ClinicalTrials.gov).

Background and Purpose: Using the passive electrodes and amplifiers with adjustable gain is very popular in laboratory for Electromyographics (EMG) measurement. However, the active electrodes, which contain pre-amplifiers and stainless-steel plates, are used in most clinical applications of kinesiological study and assistive devices control. There remains an important question: ”Can we use the algorithm developed by the passive electrodes in the applications by the active electrodes?” In this study, we try to answer this question by power spectrum analysis. Methods: Five able-body subjects were recruited in this study. The autoregressive (AR) coefficient was used to represent the spectral features of EMG signals of right upper arm via both active and passive electrodes. Maximal likelihood distance measure measurement was used to classify the difference of these spectral features. Results: It showed the estimated recognition rates of these spectral features in the passive electrodes were higher than those in the active ones (averaged recognition rate 88.5% in passive electrode recording and 85.84% in active electrode recording). However, there are not significant differences between them in statistics. Conclusion: These results imply that the differences of power spectrum that recorded via both electrodes could be negligible.

The increasing number of physically challenged individuals has boosted the demand of powered wheelchairs. This paper is on the subject of a DSP (Digital Signal Processors) based assistive system, which is associated with a two-level checking scheme. The assistive system takes on the M3S (Multiple Master Multiple Slave) regulation for the assurance of safety. The CAN (Control Area Networks) embedded module in the DSP provides robust transmission of information within the system. The hardware interfaces based on the two-level checking scheme is implemented in input devices (e.g. joystick, head control apparatus) and in output devices (e.g. manipulator, prime mover motors).

The EMG signal is a well-known and useful biomedical signal. Much information related to muscles and human motions is included in EMG signals. Many approaches have proposed various methods that tried to recognize human motion via EMG signals. However, one of the critical problems of motion pattern recognition is that the performance of recognition is easily affected by the normalization procedure and may not work well on different days. In this paper, a modified feature of the multi-channel EMG signal is proposed and the normalization procedure is also simplified by using this modified feature. To recognize motion pattern, we applied the support vector machine (SVM) to build the motion pattern recognition model. In training and validation procedures, we used the 2-DoF exoskeleton robot arm system to do the designed pose, and the multi-channel EMG signals were obtained while the user resisted the robot. Experiment results indicate that the performance of applying the proposed feature (94.9%) is better than that of conventional features. Moreover, the performances of the recognition model, which applies the modified feature to recognize the motions on different days, are more stable than other conventional features.
