This study puts the purpose in providing the scientific basis of dance motion as an artistic expression by analyzing the kinematic variable and the distribution factor of power affecting the motion, which is connected to the turn, right after the arabesque motion according to the existence and non existence of using the arm in the arabesque motion of modern dance. As a result of this study, arabesque turn motion, not using the upper limbs, used more turning force of head and body than the arabesque turn motion, using the upper limbs, and arabesque turn using the upper limbs obtained the turning force, using the right shoulder. The range of the hip joint on the left and the position change of left tiptoe in the Arabesque turn motion using the upper limbs is largely ascended to the vertical axis, while, the position of tiptoe in the Arabesque turn motion, not using the upper limbs is dropped to the lower part of each event. In the replacement of body center, Arabesque turn motion using the upper limbs is moved more to the turning axis than arabesque turn motion not using the upper limbs. As a result of maximum vertical ground reaction force, Arabesque turn motion using the upper limbs appeared to be a lower value than the Arabesque turn motion not using the upper limbs.

This paper presents a human-machine interaction based on a realtime upper limb motion prediction method using surface electromyography (sEMG). The motions were predicted using an artificial neural network algorithm and sEMG signals which are acquired from five muscles, and then a manipulator was controlled to follow after the predicted motions. Upper limb motions were restricted to 2D vertical plane with the contact condition between a user and an end-effector of manipulator. In order to demonstrate the feasibility of the proposed method, experiments using developed method and using a goniometer were performed. The results showed that the proposed real-time motion prediction method can be implemented a human-machine interaction system.

이 연구의 목적은 뇌성마비 아동에게 앉은 자세에서 현수를 이용하여 체중지지를 해주었을 때 상지기능에 어떠한 영향을 미치는지 알아보는 것이다. 연구대상자는 뇌성마비 아동 5명과 뇌종양 아동 1명이었다. 연구대상자에게 harness를 착용하여 부분적 체중지지를 하기 전과 착용한 상태에서 손 뻗기 동작을 3차원 동작분석기를 이용하여 어깨관절과 손뻗기 동작에 걸린 시간을 측정하였고, Box and Block 검사를 실시하여 체중지지 전과 착용 시 상지 기능을 비교하였다. 자료분석은 윌콕슨 부호순위검정을 사용하였다. 어깨관절의 관절 가동범위와 Box and Block 검사에서는 유의한 차이가 없었으나, 팔뻗기 동작의 수행 시간에는 유의한 차이가 있었다(p<.05). 연구 대상자의 수가 적고, 대상자 마다 연령 및 손상의 정도가 서로 다르기 때문에 연구결과를 일반화하여 해석하기에는 제한점이 있지만, 앉은 자세에서 harness를 이용하여 부분적 체중지지를 적용하였을 때 상지의 기능 향상에 도움을 줄 수 있으리라 생각하며 향후 다수를 대상으로 한 연구가 필요하리라 생각한다.

This study was conducted to investigate the effect of gradually decreasing action observation training on the upper extremity function and Activities of daily living in chronic stroke patients. For patients with chronic stroke, the groups were divided into experimental group undergoing gradually decreasing action observation training(n=4), control group receiving existing action observation training(n=3) and the study was conducted 6 times a week, 30 minutes per session for a total of 2 weeks. The results of the comparison between the groups before and after intervention and the comparison between the two groups did not show statistically significant differences in BBT, FMA, K-MBI, and MAL, but the experimental group showed a greater difference in terms of average score than the control group. As a result, it was confirmed that gradually decreasing action observation training can have a more positive effect than the existing action observation training.

The utilization of virtual reality is increasing not only in games but also in medical care such as rehabilitation. Due to the convenience, the motion of the upper limb is detected using a non-contact method using video or a handheld type mouse, etc. In this paper, we implemented a glove which can measure finger movements and upper limb movements by using flex sensors whose resistance value changes according to the degree of folding and inertial sensors which can obtain direction information in space. We showed the upper arm movements including finger movements with signals obtained from the implemented glove on the open software platform, Processing. The sensitivity of each finger movement was 0.5deg, and the sensitivity of the upper limb motion was 0.6deg.

The purpose of this study was to investigate changes in balance and upper extremity (UE) function associated with reaching training for children with quadriplegic cerebral palsy based on Biomechanical Frame of Reference. The baseline (phase A) lasted one week. The therapeutic protocol consisted of three reaching training (Phase B) for 40 minutes three times a week. Intervention phases lasted 4 weeks. The CMS-70P (Zebris Medizintechnik Gmbh, Germany) was used to evaluate the qualitative changes in UE function and Pediathc Berg Balance Scale was used to test the balance. The observed performance changes seem to be associated with the presence of intervention and suggest that biomechanical training can be a useful intervention to improve not only manual function but also balance.

In this paper, we proposed a design of upper-limb rehabilitation device with power-assist function for stroke survivals. The designed upper-limb rehabilitation device has three degrees of freedom； it is possible to perform flexion and extension motions of wrist, index finger and the other fingers except the thumb independently. The power-assist for wrist motion is performed by a pneumatic double-acting cylinder, but the fingers are actuated by electrical linear actuators to assist motions. A prototype upper-limb rehabilitation device and its controller were implemented. The position controller showed 0.8 mm errors in the steady-state. Experimental results showed that the proposed upper-limb rehabilitation device with power-assist function is feasible.

This study was performed to investigate the impact of the Neurocognitive Rehabilitation Therapy on the upper limb function recovery of patients with stroke and their abilities to perform daily activities and to provide basic data for a long-term treatment. A total of 30 patients with hemiplegia that occurred due to stroke were recruited as subjects of the present study, and 15 patients were randomly assigned to a Neurocognitive Rehabilitation Therapy group and a conventional treatment group, respectively. And, tests were performed over four weeks, five times a week, and 30 minutes a session. Manual Function Test(MFT), Fugl-Meyer Assessment Scale(FMA), and Korean-Modified Bathel Index(K-MBI) were used to measure the degree of the functional recovery before and after the experiment. According to the data of this study, in the upper limb function test, the Neurocognitive Rehabilitation Therapy group showed significant increase of the measurement values of MFT and FMA(p <.05), and when the difference between the two groups were compared, the upper limb function showed a statistically significant difference. In the daily activity performance test, only the Neurocognitive Rehabilitation Therapy group showed a significant improvement of K-MBI value(p <.05). Based on the results of the present study, it was demonstrated that the Neurocognitive Rehabilitation Therapy was effective in enhancing the upper limb functions and daily activity performance of patients with stroke.

The subjects of this study were 30 hemiplegia patients whose disease duration was over 6 months, and they were divided at random into a control group (n=15) receiving traditional rehabilitation therapy and an experimental group (n=15) receiving both traditional rehabilitation therapy and training using IT based EMG biofeedback. The program was applied for a total of 4 weeks. In order to examine the subjects' functional recovery, we measured their upper limb function using FMA and MFT, and activities of daily living using FIM before and after the training. Comparison between experimental groups in the study of upper extremity function improved after training in all tests was higher compared to the control group significantly (p<.05), but activities of daily living were not significantly different in. The results of this study were as follows. we concluded that stroke patients receving intensive IT based EMG biofeedback showed upper extremity functional recovery.
