The purpose of this study is to develop a smart device-based Language Rehabilitation Program (LRP) to improve communication ability for the patients with language disability. The content of the LRP includes a variety of semantic categories and grammatical elements and consists of 17 semantic categories, 29 tasks and 3780 items to improve comprehension/production ability at word level, semantic category level, sentence level and discourse level. We developed LRP as a Windows-base management program and an Android-base language rehabilitation application. LRP was developed into an application for smart devices, providing real-time delivery of training contents, measurement and database of training task results, and patient progress and monitoring. A follow-up study will be conducted on the verification of the language rehabilitation effect using LRP by patients with language disability.

The patients who have illness of hand and upper limb should be received rehabilitation treatment to recover such illness. The rehabilitation treatments is a treatments designed to facilitate the process of recovery from injury, illness, or disease to as normal a condition as possible. This should be done continuously and repeatedly. In this paper, we describe hand-rehabilitation system which provides a treatment method improving and recovering the function of injured hands. Expecially, this system is using a leap motion device which can easily and properly identify and trace a hand motion and provide six treatment patterns for hand rehabilitation. By using this system, the patients can do rehabilitation treatment easily and continuously in their daily life and in result, the achievement of treatment will be improved.

Gait analysis is essential for leg diagnosis and rehabilitation for the patients, the handicapped and the elderly. The use of 3D motion capture device for gait analysis is very common for gait analysis. However, this device has several shortcomings including limited workspace, visibility and high price. Instead, we developed gait estimation system using gyroscopes. This system provides gait information including the number of gaits, stride and walking distance. With four gyroscope (one for each leg's thigh and calf) outputs, the proposed gait modeling estimates the movements of the hip, the knees and the feet. Complete pedestrian localization is implemented with gait information and the heading angle estimated from the rate gyro and the magnetic compass measurements. The developed system is very useful for diagnosis and the rehabilitation of the pedestrian at the hospital. It is also useful for indoor localization of the pedestrians.

The chairbound, handicapped person often requires a cushion to distribute the supportive forces over the largest area possible in order to reduce the risk of the development of a pressure sore. Pressure sores are areas of damaged skin caused by staying in one position for too long and can cause serious infections, some of which are life-threatening. When sitting upright, the greatest proportion of body weight is centerd over the ischial tuberosities. So, it is important that comfortable seating and largest distribution of pressure to prevent pressure sores. Therefore, the objective of this study was to develop the physical pressure measurement device and orthodontic chair to prevent pressure sores.

기존의 재활치료기구는 부피가 크고 고비용으로 재활치료센터 운영시간에 맞춰 통원하며 이용해야 하는 불편함이 있었다. 이러한 불편함을 해소하기 위해 제안하는 디지털 서보모터 재활 보조기구는 사용자의 상태에 맞게 전문가와 상의하여 구동수치와 손 안쪽의 와이어의 길이를 수정 한 후 사용하는 것을 원칙으로 사용자가 손가락 끝(지문)에 부착된 감압센서를 누르는 강도와 힘의 유지 유무에 따라 손가락을 굽히거나 펴는 행위를 훈련 할 수 있도록 한 재활치료기구이다. 본 논문의 구현결과는 향후 프로토타입을 보완하여 출력과 운용 방법을 기존과 달리 한다면 다양한 재활기구에 응용될 수 있을 것으로 사료된다.

In this paper, we proposed a new system for postural balance rehabilitation training. We used the cycle simulator using virtual reality technology as the sensory integration device. Our results showed that this system was effective postural balance rehabilitation training device and might be useful as the clinical equipment.

This study proposes an industrial rehabilitation robot system which can exercise two joints in 3 dimensional spaces. The robot kinematics analysis and the results of studies on each joint for the rehabilitation robot could verify possibility of rehabilitation motion to exercise a joint. The force and torques sensor not only measures a rehabilitation performance of subjects between the abnormal limb and the manipulator, but also carries out an important function of safety device to prevent accidents. Also, limit sensors and emergency stop switch are used for high safety in this system. In this real test, the possibility of rehabilitation robot system is evaluated by C&R ARM I which is similar to upper-limb.

Objectives: The aim of this review was to investigate studies on fire needle and to propose for the better method of studies in the future. Methods: Studies related to fire needle were searched with electric database for this study, and 10 domestic and overseas databases were included. Results: 19 clinical studies were analyzed in terms of condition, time of heating, number and frequency of treatment, number of heating, safety procedure or device aid reports of adverse events. Also 3 review studies were summarized. The number of studies was increasing and the kind of diseases to treat with fire noodle were various. Especially musculoskeletal diseases like ligament lesion and lumbago were noticeable. Heating-after-insertion method was recently proposed but the use of term was confusing. The report of adverse events or safety procedure was rare. Also there was an effort to develop more convenient and safer device. Conclusions: High quality clinical trial en fire needle is needed especially to compare 2 methods, heating-after-insertion and heating-before-insertion. And studies need to report safety procedures and adverse events to evaluate the safety of fire needle therapy.

Objective: In this study, the test-retest reliability and validity were presented to evaluate the usability of isokinetic rehabilitation equipment for the knee joint. Design: Cross-sectional design, reliability & validity study. Methods: Thirty healthy adults participated in the study. A CSMI dynamometer was used as a standardized measuring device to present the validity of the equipment. It was measured based on the dominant leg. The average peak torque value was selected as the measurement variable. After the measurement, a questionnaire was conducted on safety, satisfaction, and performance through the usability evaluation questionnaire. Results: The knee joint isokinetic rehabilitation equipment showed high reliability with Intraclass Correlations Coefficients (ICC) =0.883~0.956. In order to check the validity of the equipment, the 95% confidence interval of the mean difference limit was confirmed by the Bland & Altman plot. As a result, all three angular velocities showed a smaller confidence interval in the flexion than in extension. There were less than 10 plots that were not included in 2 Standard Deviation (SD) between all measurements. As a result of the usability evaluation questionnaire, the average of the safety domain(4.9±0.4), satisfaction domain(4.1±0.8), performance domain(4.3±0.8). Conclusions: If the product is improved by supplementing the items identified in the usability evaluation process, it is judged that it can be used as a useful device in various knee joint rehabilitation fields.
