본 연구는 뇌졸중으로 인한 성인 편마비 환자의 계단 높이에 따른 보행 훈련을 통하여 균형과 근활성도 변화를 분석하는데 목적이 있다. 뇌졸중으로 진단받은 편마비 환자 30명을 대상으로 5cm, 10cm, 15cm 높이의 계단 보행 훈련군으로 나누어 계단 보행 훈련을 실시하였으며, 임상적 균형능력 측정도구인 Berg Balance Scale(BBS), Timed up and go(TUG), Functional Reach Test(FRT)와 근활성도를 측정하였다. 연구결과 균형변화에서는 세 군간 계단 보행 훈련 전과 후의 균형 변화량이 통계학적으로 유의한 차이가 나타나지 않았으나(p>.05), 10cm 높이 계단 보행 훈련군에서 가장 큰 변화량을 보였다. 근활성도변화에서는 계단 오르기시 10cm 높이 계단 보행 훈련군에서 넙다리곧은근, 넙다리두갈래근, 장딴지근, 15cm 높이 계단 보행 훈련군에서 모든 근육들이 통계학적으로 유의한 차이를 보였으며(p<.05), 계단 내리기시 근활성도 변화에서는 5cm 높이계단 보행 훈련군에서 앞정강근와 장딴지근, 10cm 높이 계단 보행 훈련군에서 모든 근육들이, 15cm 높이 계단 보행 훈련군에서 넙다리두갈래근, 앞정강근, 장딴지근이 통계학으로 유의한 차이를 나타내었다(p<.05). 따라서, 높이에 따른 계단 보행 훈련은 편마비 환자의 임상적 균형 능력과 근활성도를 변화시키는데 영향을 줄 수 있으며, 특히 10cm 높이 계단 보행 훈련군에서는 다른 높이의 계단 보행 훈련군에서 보다 약간 상대적인 증가를 보였다.

뇌졸중으로 인한 편마비 장애인은 뇌손상으로 인해 운동 및 감각 신경 통로의 장애가 있어, 기립 및 보행 시 비정상적인 행태를 보이는 경우가 많다. 과도한 외회전은 보행 시 안전성을 보장 받기 어려워 낙상 등 신체적 위험에 처할 수 있고, 또한 비장애인의 보행과의 시각적 차이로 인하여 환자들의 심리적 위축감을 가중시킬 수 있다. 본 연구에서는 외회전 보행 시 편마비 장애인에게 피드백을 주어 자가 교정이 가능하도록 시스템을 개발하였으며, 이는 외회전 보행을 하는 편마비 장애인의 보행 교정에 도움이 될 것으로 기대된다.

In this paper, we have developed a portable acceleration measurement system to measure acceleration signals during walking and a gait analysis algorithm which can evaluate gait regularity and symmetry and estimate gait parameters automatically. Portable acceleration measurement system consists of a biaxial accelerometer, amplifiers, lowpass filter with cut-off frequency of 16Hz, one-chip microcontroller, EEPROM and RF(TX/RX) module. The algerian includes FFT analysis, filter processing and detection of main peaks. In order to develop the algorithm, eight hemiplegic patients for training set and the other eight hemiplegic patients for test set are participated in the experiment. Acceleration signals during 10m walking were measured at 60 samples/sec from a biaxial accelerometer mounted between L3 and L4 intervertebral area. The algorithm, detected foot contacts and classified right/left steps, and then calculated gait parameters based on these informations. Compared with video data and analysis by manual, algorithm showed good performance in detection of foot contacts and classification of right/left steps in test set perfectly. In the future, with improving the reliability and ability of the algerian so that calculate more gait Parameters accurately, this system and algerian could be used to evaluate improvement of walking ability in hemiplegic patients in clinical practice.

An interactive wireless-game device based on multi-channel electromyogram has been developed to help rehabilitation of patients with hemiplegia. The device is able to provide a visual feedback and rehabilitation motivations to the patients. The game contents were made according to the number of applied channels and, their level and speed can also be controlled depending on the recovery states of patients. Patient satisfaction survey was conducted to evaluate the necessity and usefulness of the proposed device after playing the game. The results show that the proposed system is expected to give hemiplegia patients exciting and effective rehabilitation chances, if more diverse and specialized rehabilitation games are developed.

Objective : This study evaluated the differences between the upper and lower arm activities of the affected and non-affected sides in stroke patients performing activities of daily living. It was intended to gather basic data for the measurement of daily activities. Methods : The participants in the study consisted of 20 patients, 10 had left hemiplegia and 10 had right hemiplegia. Between September and November 2017, they performed drinking and dressing as unimanual and bimanual tasks. The 3-axes accelerometers were placed 2cm below the lateral epicondyle on the upper arm and 2cm below the radial styloid on the lower arm. The data were collected at intervals of 1/32 Hz and analyzed. Results : In patients with right hemiplegia, the tendon activity was significantly higher in the lower arm when performing a bimanual activity (p<.05), for all the other activities, those of the lower arm were significantly higher than those of the upper arm (p<.01, p<.05). There was no significant difference between the unimanual and bimanual activities of the affected and tendon sides in patients with left hemiplegia (p>.05). In both hands, the activity of the lower arm was significantly higher than that of the activities of the upper and lower arms, except on the affected side (p<.05). In all patients, the activities of the upper and lower arms were significantly higher (p<.05), and the activity of the lower arm was significantly higher than that of the upper (p<.001, p<.05). Conclusion : The activity was higher on the non-affected side than the affected side during the dressing task, and the overall activity was higher in the lower arm than the upper arm.
