대한민국 특허출원 제2009-104339호에 개시된 바와 같이, 일반적으로 신경계의 손상과 질환은 운동기능 및 감각기능의 장애를 초래하게 되고, 일상생활동작의 기능제한과 함께 근위축, 근구축, 근건 단축, 관절운동장애, 골다공증, 만성통증 등 다양한 합병증과 속발증을 초래하게 된다. 그러나 신경계의 손상과 질환에 대해서는 그 원인 진단과 증상 완화에 초점을 둔 치료법이 주로 사용되고 있으며, 신경 손상에 따른 운동기능의 마비나 감각기능의 회복을 위한 본질적인 치료법은 그리 많지 않은 것이 현실이다. 신경계 손상에 따른 감각기능이나 운동기능 손실은 신경의 손상 정도에 따라 다소 차이가 있으나 각종 사고에 의한 중추신경의 절단이나 손상의 경우 완전한 회복을 기대하기가 거의 불가능하며, 뇌졸중, 뇌종양과 같은 신경계 질환에 의한 신경손상 역시 완전한 회복이 어렵고, 부분적인 회복 상태로 평생 여명동안 장기적인 기능장애를 초래하게 된다. 이로 인한 운동기능 및 감각기능의 상실은 일상생활을 영위하는데 가장 기본적인 동작마저 제한하여 사람다운 삶을 영위하기가 어렵고, 활동제한으로 장기간 근육을 사용하지 못함에 따른 근위축, 근구축, 근건 단축, 근강직과 혈행순환 장애에 따른 피부괴사 등 중대한 합병증과 속발증이 불가피하게 수반되게 되어 지속 재활치료가 여명기간 필수적으로 제공되어야 하는 상태가 된다. As disclosed in Korean Patent Application No. 2009-104339, damage and diseases of the nervous system generally cause impairment of motor function and sensory function, and are accompanied by functional limitations of daily living movement, muscle atrophy, muscle building, Joint movement disorder, osteoporosis, chronic pain and various complications and will result in secondary. However, for the damage and disease of the nervous system, the treatment method focusing on the cause diagnosis and the symptom relief is mainly used, and there is not so much essential treatment for the recovery of numbness or sensory function due to nerve injury. Sensory function and motor function loss due to nervous system damage are somewhat different depending on degree of nerve damage, but it is almost impossible to expect complete recovery in the case of cutting or damage of central nervous system caused by various accidents, and neurological diseases such as stroke and brain tumor Nerve damage is also difficult to complete recovery, and partial restoration results in long-term dysfunction during lifetime. The loss of motor function and sensory function caused by this resulted in the limitation of the most basic movement in daily life, making it difficult to carry out human life, and the inability to use long-term muscles due to limitation of activity, Severe complications such as skin necrosis due to muscle stiffness and circulatory disturbances and inevitably accompanied by a secondary event, making it necessary for continuous rehabilitation therapy to be provided during the longevity period.
이러한 이유로, 최근 중추신경계 질환과 손상으로 인한 상, 하지 마비환자에서 감각운동성 신경기능을 회복시키는데 주안점을 두어, 일상생활동작기능을 보조하고 증진시키거나, 이동과 보행능력을 향상시키기 위해 신경자극조율치료의 일환으로 여러 가지 전기자극기가 개발되고 있다. For this reason, in recent years, it has been proposed to improve sensory motor nerve function in patients with upper and lower paralysis caused by central nervous system diseases and damage, to support and enhance the daily living movement function, to improve the movement and walking ability, Several electrical stimulators have been developed as part of therapy.
그러나 이러한 종래의 전기자극기는 전기자극기에 내장된 패턴에 따라 근육에 전기자극을 가해주는 방식만 가능한 피동치료법이기 때문에 환자가 단지 전기자극기의 '자극'이란 단순 기능에만 의존하게 될 뿐만 아니라 흥미를 유발할 수 있는 요소가 없어, 적극적인 재활 동기부여를 제공하여 주지 못하여 여명기간 치료요망 상태에서 '지속가능한 신경자극조율치료'를 장기간 적용해야 하는 측면을 고려할 때 장기간 효율적인 치료가 불가능한 문제점이 제기되어 왔다. However, since such a conventional electric stimulator is a passive treatment method which can be applied only to a method of applying electrical stimulation to the muscles according to a pattern embedded in the electric stimulator, the patient merely relies on the simple function " stimulation " In the present study, it was found that the long-term effective therapy was not possible in the long-term application of 'Sustainable Nerve Stimulation Therapy' in the long-term treatment demand condition because it does not provide active rehabilitation motivation.
특히 상지의 경우 기본 일상생활동작 중 식사동작, 착탈의동작, 개인위생동작 등 기능 수행에 필수적인 팔 및 손가락의 움직임 활성화를 위한 동작-특성화된 맞춤형 상지 신경근육자극치료 기기 개발이 거의 부재하며, 기능적 전기자극 치료 내용도 바이오피드백 형태로 제공되지 못하는 등 문제점이 있어 왔다.In particular, in the case of the upper extremity, there is almost no development of the operation-specific customized upper limb muscle stimulation treatment device for activation of the arm and the finger which is essential for the performance of the function such as the eating motion, the detachment motion and the personal hygiene motion, Electric stimulation therapy contents can not be provided in the form of biofeedback.
본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 중추신경계 질환이나 손상으로 팔과 손가락의 움직임이 감소되었거나 근긴장도 조절의 이상으로 자연스럽지 못하고 재활 치료를 받아야 하는 사용자의 신경과 근육 기능을 활성화하도록 하고, 치료놀이적 개념으로 흥미로운 치료프로그램을 구성하여 사용자의 치료동기 유발을 통해 수동 및 능동적 참여를 유도하기 위해 다양한 모드로 구성하여 시스템이 동작되고, 사용자의 상지의 감각운동성 기능 수준에 따라 수동 훈련, 능동 훈련을 선택하고 흥미를 유발하기 위해 PC 콘텐츠와 결합하여 컴퓨터 게임을 하듯이 훈련할 수 있어, 재활 능률을 향상시키는 신경기능 회복을 위한 재활 훈련 장치를 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for a user who has suffered from a central nervous system disease or injury and whose arm and finger movements are reduced, In order to induce passive and active participation through user motivation induction by constructing an interesting therapeutic program with the nerve and muscle function being activated and the therapeutic play concept, various modes are operated and the system is operated, And to provide a rehabilitation training device for recovery of neurological function that can improve the efficiency of rehabilitation by being able to train like a computer game in combination with PC contents in order to select passive training and active training according to mobility function level .

본 발명의 수동, 능동 훈련이 가능한 바이오피드백 상지 기능적 전기자극 장치는, 도 2 및 도 3에 도시된 바와 같이, 기기의 설정에 따라 4종류의 훈련 모드로 구동되며, 전기자극 장치에 의해서만 구동되는 수동모드와, 휨센서 피드백을 이용하여 전기자극하는 능동 보조모드와, PC(personal computer) 프로그램과 결합된 휨센서 피드백을 이용하여 전기자극하는 PC 결합형 능동 보조모드와, 상기 PC 프로그램과 휨센서의 움직임을 이용하여 훈련하는 PC 결합형 능동모드로 구성된다. As shown in FIGS. 2 and 3, the biofeedback upper limb functional electrical stimulation apparatus capable of manual and active training according to the present invention is driven in four kinds of training modes according to the setting of the apparatus and is driven only by the electric stimulation apparatus A passive mode, an active assist mode in which electric stimulation is performed using bending sensor feedback, a PC assisted active assist mode in which electric stimulation is performed using bending sensor feedback combined with a PC (personal computer) program, And a PC-coupled active mode in which the robot performs training using the motion of the robot.
상기 수동모드는 휨센서의 피드백 없이 손목 신전근과 굽힘근에 전극을 부착하여 전기 자극에 의해서 손목을 움직일 수 있는 모드이다. The manual mode is a mode in which an electrode is attached to a wrist extension and a bending muscle without feedback of a bending sensor to move the wrist by electric stimulation.
상기 능동 보조모드는 손목 신전근과 굽힘근에 전극을 부착하고, 환자의 손가락 및 손목의 움직임을 휨센서를 통해 환자가 움직일 수 있는 범위를 설정한 후 전기 자극 세기를 휨센서의 설정 범위 내에서 자동으로 자극세기를 조절할 수 있는 모드이다. In the active assist mode, an electrode is attached to a wrist extension and a bending muscle, and a range of movement of the patient's finger and wrist through a bending sensor is set, and then the electric stimulus intensity is automatically Is a mode that can control the intensity of the stimulus.
이때 설정한 범위에 가까이 들어오면 올수록 자극의 세기는 약해지며 멀어지면 자극의 세기의 강도가 강해져 휨센서의 범위만큼 훈련할 수 있는 능동보조 훈련모드이며, 손목 신전과 굽힘을 한 번씩 번갈아 가면서 훈련할 수 있는 모드이다. At this time, the closer to the set range, the weaker the strength of the stimulus, and the stronger the strength of the stimulus is stronger when it is far away, the active assistant training mode can be trained by the range of the bending sensor, training to alternate wrists and bending Mode.
상기 PC 결합형 능동 보조모드는 손목 신전근과 굽힘근에 전극을 부착하고, 환자의 손가락 및 손목의 움직임을 휨센서를 통해 환자가 움직일 수 있는 범위를 설정한 후 전기자극 세기를 휨센서의 설정한 범위안에서 자동으로 자극세기를 조절하고 PC 프로그램에 의해 구동되는 모드이다. In the PC-assisted active assist mode, the electrode is attached to the wrist extension and the bending muscle, and the range of movement of the patient's finger and wrist through the bending sensor is set, and then the electric stimulation intensity is set by the bending sensor It is a mode controlled by a PC program that automatically adjusts the intensity of the stimulus within the range.
이때 PC 프로그램의 콘텐츠가 잡기 동작을 유도할 경우 환자 스스로 손목 굽힘근의 움직임에 따라 전기 자극을 가해 휨센서의 설정한 범위에 가까이 들어오면 올수록 자극의 세기는 약해지며 멀어지면 자극의 세기의 강도가 강해져 환자가 스스로 물체를 잡을 수 있는 훈련모드이며, PC 프로그램의 콘텐츠가 놓기 동작을 유도할 경우 환자 스스로 손목 신전근의 움직임에 따라 전기 자극을 가해 휨센서의 설정한 범위에 가까이 들어오면 올수록 자극의 세기는 약해지며 멀어지면 자극의 세기의 강도가 강해져 환자가 스스로 물체를 놓을 수 있는 훈련모드이다. In this case, when the contents of the PC program induce the catching motion, the stimulation intensity becomes weaker as the patient approaches the set range of the bending sensor by applying the electric stimulation according to the movement of the wrist bending muscle itself. This is a training mode in which a patient can hold an object by himself or herself. When a content of the PC program induces a dropping motion, the patient himself or herself makes an electrical stimulation according to the movement of the wrist extension, Is weakened and the intensity of the stimulus becomes stronger as it goes away, so the patient can put the object by himself.
상기 PC 결합형 능동모드는 환자의 손가락 및 손목의 움직임을 휨센서를 통해 환자가 움직일 수 있는 범위를 설정한 후 휨센서와 PC 프로그램과 함께 구동되는 모드이다. 이때 PC 프로그램의 콘텐츠가 잡기 동작을 유도할 경우 환자 스스로 손목과 손가락의 굽히는 움직임에 따라 휨센서의 설정한 범위에 들어오면 물체를 잡을 수 있는 훈련모드이며, PC 프로그램의 콘텐츠가 놓기 동작을 유도할 경우 환자 스스로 손목과 손가락의 펴지는 움직임에 따라 휨센서의 설정한 범위에 들어오면 물체를 놓을 수 있는 훈련모드이다. The PC-coupled active mode is a mode in which a range of a patient's finger and wrist movement can be moved through a bending sensor and then is driven together with a bending sensor and a PC program. In this case, if the content of the PC program induces the catching motion, the patient can catch the object when the bending sensor detects the bending motion according to the bending motion of the wrist and the finger, It is a training mode in which the patient can place objects when he or she enters the set range of the bending sensor according to the wrist and finger spreading motion.
도 1에 도시된 바와 같이, 상기 휨센서는 손가락 관절마다에 부착된 5개의 관절별 센서와, 손목에 부착되는 손목 휨센서로 구성된다. As shown in FIG. 1, the bending sensor includes five joint sensors attached to each finger joint and a wrist bending sensor attached to the wrist.
손목에는 2채널 FES를 고정하는 전극부착기구물과 손목고정기구물이 설치되어 있다. 상기 2채널 FES는 피드백할 수 있도록 PC와 연결되어 있다. An electrode attaching mechanism and a wrist fixing mechanism are provided on the wrist to fix the 2-channel FES. The 2-channel FES is connected to the PC for feedback.
