Objectives This study was conducted to evaluate the therapeutic effect of herbal medicine after total knee arthroplasty. Methods Key words such as total knee arthroplasty and herbal medicine were searched in 10 databases (Ovid-Medline, Ovid-EMBASE, Ovid-AMED, Cochrane Library, China National Knowledge Infrastructure [CNKI], National Digital Science Library [NDSL], Koreanstudies Information Service System [KISS], Oriental medicine Advanced Searching Integrated System [OASIS], KoreaMed, KMBASE), and only suitable randomized controlled trials (RCTs) were selected. Results 8 RCTs were finally selected, and herbal medicine showed positive results for pain relief and functional recovery after total knee arthroplasty. However, the analyzed 8 RCTs showed a high overall risk of bias. Conclusions In the future, RCTs with a higher level of evidence on the effect of herbal medicine after total knee arthroplasty need to be continuously conducted.

Despite intensive therapy, a large proportion of stroke survivors are left with significant disabilities. To improve the disable condition, a major component of stroke management is aimed at facilitating functional independence and community reintegration. There are many evidences that community-based rehabilitation after stroke is most effective when provided by a well-organized multidisciplinary team. Key to the implementation of community-based rehabilitation(CBR) is that the disabled person, their family and their community decide on what the priorities of the service should be. The stroke patients in the community need a wide range of services, including the traditional rehabilitation services of physiotherapy, occupational therapy, speech therapy, social workers, orthotists, nurses and so on. The purpose of this research was to investigate necessity and methods of community-based rehabilitation system in Korea.

Objectives : This study was performed to identify the influence of salivary cortisol and HRV(Heart rate variability) on hypoadrenia predisposing factors and sign. Methods : 30 patients with chronic fatigue symptom belonging to Shen xu(腎虛) were recruited for investigation from March to April 2007. The participants were divided into HS(High score) group(n=15) and LS(Low score) group(n=15) in predisposing factors of adrenal questionnaire. At the same time equal patients separated into OH(+)(Orthostatic hypotension positive) group(n=12) and OH(-)(Orthostatic hypotension negative) group(n=18). Salivary cortisol and HRV made use of evaluating hormonal imbalance and autonomic nervous system of hypoadrenia. Results : Salivary cortisol at P.M.4 in HS group was significantly(p=0.011) lower than LS group. And LF(Low frequency) of OH(+) group was considerably(p=0.014) lower than OH(-) group. Conclusions : Shen xu bian zheng(腎虛辨證), measure of orthostatic hypotension, predisposing factors of adrenal questionnaire, salivary cortisol and HRV deserve clinical application for management of subclinical hypoadrenia.

In the paper, we developed the mobile based rehabilitation system for patients with upper extremity hemiplegia after stroke and evaluated clinical usefulness and effectiveness of the system. The sensors built in the smartphone were used to track patients' upper limb motion and the movements was transferred to the tablet PC through bluetooth connection so that the game contents could be interact with the movements. The rehabilitation game contents was based on Brunnstrom stage(B-stage), and was designed to lead accurate movement of upper limb. For the clinical evaluation of the effectiveness, 11 patients were recruited and make them perform an exercise of their wrist, shoulder, and forearm using the system for two weeks. The change of upper limb motor function was measured using fugl-meyer assessment(FMA), Brunnstrom stage(B-stage). And the change of quality of life was measured using EuroQoL-5 Dimension(EQ-5D), Beck Depression Inventory(BDI). The results showed significant improvement in upper limb function but not in quality of life. We verified mobile based rehabilitation program could be useful and effective for the clinical use.

Bridges are rated at two levels by either Load Factor Design (LFD) or Allowable Stress Design (ASD). The lower level rating is called Inventory Rating and the upper level rating is called Operating Rating. To maintain bridges effectively, there is an urgent need to assess actual bridge loading carrying capacity and to predict their remaining life from a system reliability viewpoint. The lifetime functions are introduced and explained to predict the time-dependent failure probability. The bridge studied in this paper was built 30 years ago in rural area. For this bridge, the load test and rehabilitation were conducted. The time-dependent system failure probability is predicted with or without rehabilitation. As a case study, an optional rehabilitation is suggested, and fir this rehabilitation, load rating is computed and the time-dependent system failure probability is predicted. Based on rehabilitation costs and extended service lifes, the optimal rehabilitation is suggested.

Weight bearing is effective during rehabilitation of gait, in the elderly and disabled people. Various training devices using weight bearing function were developed along with treadmill walking; however, no device has been developed in conjunction to walking on the ground. Here, we designed a rail type frame of a gait rehabilitation system for body-weight support (BWS) function, and analyzed its mechanical safety in the static weight bearing condition of a vertical axis. Computational simulations were performed to analyze structure of the driving parts, which are connected with a rail and driving rollers and the lower plate of the BWS. Structural analyses showed the drivers and BWS were safe, when simulated at 135kg weight under static conditions. Thus, this rail type rehabilitation system can be used for gait training of the elderly and disabled.

This study proposes an automated pegboard utilizing the RFID system with multiple reader antennas for the rehabilitation services and the occupational therapy. The system automates the scoring by detecting the plugging correctness as well as the plugging status. It also aims to increase the patient's interest and the functional intelligence. The system was prototyped and tested for the automatic capability of the scoring the session time and success rate. The proposed system will be served as the typical example for the ubiquitous rehabilitation devices.

This paper describes a development of rehabilitation training system for the postural balance control. A new rehabilitation training system, designated as a virtual cycling system, was developed to improve postural balance control by combining virtual reality technology with an unfixed bicycle. In this experiment, 20 normal adults were tested to investigate the influencing parameters of postural balance control. In order to evaluate the usefulness and the training effects of the system, several parameters Including path deviation, cycling velocity, cycling time, center of pressure, and head movement were evaluated and analyzed quantitatively. Also, to improve the effect of balance training, the visual feedback information related to the subject´s weight shift was ...
