Description

표면 근전도 측정이 가능한 웨어러블 디바이스Wearable device capable of measuring surface EMG
본 발명은 표면 근전도 측정이 가능한 웨어러블 디바이스에 관한 것이다.The present invention relates to a wearable device capable of measuring surface EMG.
근전도검사(electromyography, EMG)는 골격근에서 발생하는 전기적인 신호를 측정하고 기록하는 기술로서, 신경과 근육에서 발생하는 전기적 신호를 기계를 통해 분석해 말초신경이나 신경 주변 및 근육의 이상이 있는지 보기 위한 검사이다. Electromyography (EMG) is a technology that measures and records electrical signals generated from skeletal muscles. Electrical signals generated from nerves and muscles are analyzed through a machine to check for abnormalities in peripheral nerves, nerves, and muscles. to be.
이러한 근전도검사를 시행하는 방법으로는 바늘로 근육을 찔러 시행하는 근육 내 침근전도 검사와, 피부에 전극을 붙여 검사하는 표면 근전도 검사로 나뉘어 시행되고 있는 실정이다. As a method of conducting such an electromyography, it is divided into intramuscular needle electromyography, which is performed by piercing the muscle with a needle, and surface electromyography, which is performed by attaching electrodes to the skin.
침근전도 검사의 경우 검사자의 지시에 따르지 않고 움직이게 될 경우 부상으로 이어질 수 있고, 바늘 삽입한 부위의 통증 및 출혈이 발생할 수 있는 문제점으로 피부에 붙여서 표면에 전극이 밀착되는 근전도 검사 방법이 그 대안으로 선택되었다. In the case of needle electromyography, movement without following the instructions of the examiner can lead to injury, and pain and bleeding may occur at the site where the needle is inserted. As an alternative, the electromyography method, in which electrodes are attached to the skin and adhered to the surface, is a problem. was chosen
발목 염좌는 가장 흔한 발목 손상 중의 하나로서 최근 다양한 종류의 스포츠와 신체 활동이 늘어나게 됨에 따라 발목 염좌의 발생도 증가하고 있다.Ankle sprain is one of the most common ankle injuries, and as various types of sports and physical activities have recently increased, the occurrence of ankle sprains has also increased.
이런 발목 염좌에 대한 적절한 치료가 이루어지지 못할 경우 결국 만성 외측 발목 인대 불안정으로 진행되고 이는 장기적으로 발목의 퇴행성 관절염으로 이어지게 되는 자연경과를 보인다.If proper treatment for such an ankle sprain is not performed, it eventually progresses to chronic lateral ankle ligament instability, which shows a natural course that leads to degenerative arthritis of the ankle in the long term.
반복된 발목 염좌의 누적 결과로 인한 만성 외측 발목 인대 불안정성이 발생된 환자에서 6개월 이상 지속되는 증상 및 동반된 관절 질환 여부, 환자의 활동정도 등에 따라 선별적으로 수술적 치료(인대 재건술)를 결정한다.In patients with chronic lateral ankle ligament instability due to the cumulative result of repeated ankle sprains, selective surgical treatment (ligament reconstruction) is determined depending on symptoms lasting more than 6 months, whether there are accompanying joint diseases, and the patient's activity level. do.
발목 불안정성은 크게 기계적 불안정성과 기능적 불안정성으로 구분할 수 있는데, 기계적 불안정성은 해부학적 조직의 손상으로 인해 관절의 느슨함을 신체 진찰을 통해 확인할 수 있다.Ankle instability can be largely classified into mechanical instability and functional instability.
기능적 불안정성은 반복적인 염좌로 인해 근력, 관절가동범위, 협응력, 고유수용성 감각의 저하, 자세조절능력 부족으로 인한 환자의 주관적 감각에 의한 불안정성을 의미한다.Functional instability refers to instability caused by the subjective sensation of the patient due to a decrease in muscle strength, range of motion, coordination, and proprioception and lack of postural control due to repetitive sprains.
그러므로 발목 손상은 기계적 회복과 기능적 회복을 모두 고려하여 치료해야 한다. Therefore, ankle injuries should be treated by considering both mechanical and functional recovery.
선행연구에서 슬관절 전방십자인대 재건술이나 슬관절 인공관절치환술, 고관절 인공관절치환술을 시행하기 전 환자에게 운동치료요법을 적용하여 통증과 근력, 관절가동범위, 고유수용성감각 등 기능적인 회복이 더 빠르게 나타난 바 있다. In previous studies, exercise therapy was applied to patients before anterior cruciate ligament reconstruction, knee joint arthroplasty, or hip joint arthroplasty, and functional recovery such as pain, muscle strength, range of motion, and proprioception was found to be faster. there is.
또한 운동을 통해 근력 및 손상 인대 조직의 상태를 최대한 회복시키고 이를 유지하면서 수술을 진행한다면 수술 후에 보다 빠른 회복을 기대할 수 있을 것이다. In addition, if the state of muscle strength and damaged ligament tissue is restored as much as possible through exercise and the operation is performed while maintaining it, a faster recovery after surgery can be expected.
발목 염좌에 대한 적절한 치료가 이루어지지 못할 경우 결국 만성 외측 발목 인대 불안정으로 진행되고 이는 장기적으로 발목의 퇴행성 관절염으로 이어지게 되는 자연경과를 보이게 된다.If proper treatment for an ankle sprain is not performed, it eventually progresses to chronic lateral ankle ligament instability, which shows a natural course that leads to degenerative arthritis of the ankle in the long term.
발목외측 인대 재건술을 시행하기에 앞서 수술 전 운동프로그램을 시작하면 수술 후 나타날 수 있는 통증, 관절가동범위, 균형능력 등에 더욱 빠른 회복을 나타낼 것으로 기대된다.If a preoperative exercise program is started prior to ankle lateral ligament reconstruction, it is expected that postoperative pain, joint range of motion, and balance ability will show a faster recovery.
수술 전 4주간의 운동프로그램은 만성 발목 인대 불안정성을 가진 환자에서 나타나는 근력 약화, 균형능력 저하, 관절가동범위 제한 등을 보완할 수 있는 것으로 기대 된다.A 4-week exercise program before surgery is expected to compensate for muscle weakness, balance loss, and limited range of motion in patients with chronic ankle ligament instability.
본 발명은 표면 근전도 측정이 가능한 웨어러블 디바이스를 제공함을 그 목적으로 한다.An object of the present invention is to provide a wearable device capable of measuring surface EMG.
더 나아가 만성 발목 외측 불안정성을 가진 환자의 수술 전 운동치료요법 교육을 선행하고 수술 후 발목 통증, 관절가동범위, 균형 및 기능적 회복에 미치는 영향을 규명함을 목적으로 한다. Furthermore, the purpose of this study is to precede preoperative exercise therapy education for patients with chronic ankle lateral instability and to identify the effects on ankle pain, joint range of motion, balance and functional recovery after surgery.
또한, 본 발명은 급성 발목 염좌 후 만성 외측 발목 인대 불안정성으로 악화되는 소견이 확인되면 임상적으로 대개 수술적 치료를 권하므로 수술 전 통증 및 기능적 상태가 수술 후에도 영향을 미칠 수 있어서 수술 전 근력 및 손상된 인대 조직을 최상의 상태로 회복시키기 위한 운동치료요법 및 교육의 병행을 통한 수술 후 빠른 기능의 회복을 목적으로 한다. In addition, the present invention generally recommends surgical treatment clinically when findings worsening with chronic lateral ankle ligament instability after an acute ankle sprain are confirmed, so preoperative pain and functional status may affect postoperative muscle strength and damage before surgery. The goal is to restore the ligament tissue to its best state through exercise therapy and education in parallel to quickly restore function after surgery.

도 5는 본 발명의 밴드체(100)에 측정체(200)의 결합상태를 보인 단면을 나타낸다. Figure 5 shows a cross section showing the coupling state of the measuring body 200 to the band body 100 of the present invention.
상기 밴드체(100)의 밴드(110) 상면에 결합된 착탈체(300)는 가요성이 있는 실리콘 소재로 형성되므로 착탈체(300)의 지지홀(330) 속으로 측정체(200)를 삽입시키기 위해 착탈체(300)와 일체로 된 지지테(310)의 내측단을 들어 올리면서 측정체(200)를 지지홀(330)로 밀어 넣어 측정체(200)가 지지홀(330) 공간으로 진입되게 한다. Since the detachable body 300 coupled to the upper surface of the band 110 of the band body 100 is made of a flexible silicone material, the measuring body 200 is inserted into the support hole 330 of the detachable body 300 In order to do this, the measuring body 200 is pushed into the support hole 330 while lifting the inner end of the support frame 310 integrated with the detachable body 300 so that the measuring body 200 moves into the support hole 330 space. let it enter
상기 측정체(200)가 착탈체(300)의 지지홀(330) 속으로 삽입되면 지지테(310)는 측정체(200)의 상단 테두리에 탄성적으로 밀착되는 상태가 되고, 동시에 측정체(200)의 저면으로 돌출된 접촉부(210)는 지지홀(330) 바닥에 형성된 통공(120)의 공간에 위치한다.When the measurement body 200 is inserted into the support hole 330 of the detachable body 300, the support frame 310 is elastically adhered to the upper edge of the measurement body 200, and at the same time the measurement body ( The contact portion 210 protruding to the bottom surface of the 200 is located in the space of the through hole 120 formed at the bottom of the support hole 330 .
이처럼 측정체(200)가 착탈체(300)의 지지홀(330) 공간 내에 장착되면 지지테(310)는 측정체(200)의 상면 테두리 외주연 전체를 탄성력으로 누르고 있으므로 안정된 장착상태가 유지된다.As such, when the measuring body 200 is mounted in the space of the support hole 330 of the detachable body 300, the support frame 310 presses the entire outer periphery of the upper surface of the measuring body 200 with elastic force, so that a stable mounting state is maintained. .
이와 같은 안정된 장착상태의 측정체(200)의 저면으로 돌출된 접촉부(210)는 상기 밴드체(100)의 중간 위치에 천공된 통공(120)으로 진입되어 밀착대(130)의 표면, 즉 피부와 닿은 위치에 노출되는 상태가 되므로 접촉부(210)의 단자(220)가 측정하고자 하는 환자의 발목 부위 피부에 밀착되는 상태가 된다. The contact portion 210 protruding to the bottom surface of the measuring body 200 in a stable mounting state enters the through hole 120 drilled at the middle position of the band body 100 and enters the surface of the contact band 130, that is, the skin. Since the terminal 220 of the contact part 210 is in a state of being exposed to the contacted position, the terminal 220 is in close contact with the skin of the patient's ankle to be measured.
상기 측정체(200)가 장착된 상태에서 밴드체(100)의 밴드(100)를 발목에 두르면 밴드(110)의 양단에 형성된 고정부재(150)가 상호 맞닿아 결합된다. When the band 100 of the band body 100 is wrapped around the ankle in a state where the measuring body 200 is mounted, the fixing members 150 formed at both ends of the band 110 come into contact with each other and are coupled.
상기 고정부재(150)는 맞닿는 부분에 상호결합력이 제공되는 벨크로 테이프 또는 스냅단추 그리고 너클 중 어느 하나의 것을 선택할 수 있다. The fixing member 150 may select any one of a Velcro tape or a snap button and a knuckle providing mutual coupling force to a contact portion.
이러한 밴드체(100)를 발목에 착용하면 발목 피부에 닿는 밀착대(130) 소재의 점착성의 특징으로 발목 부위에 점착되는 상태로 접촉된다. When such a band body 100 is worn on the ankle, it is in contact with the ankle in a state of being adhered to the ankle due to the adhesiveness of the material of the contact band 130 in contact with the ankle skin.
또한, 밀착대(130)의 표면이 곡면형태의 요철형상을 이루고 있어 피부와의 접촉을 더욱 안정되게 하므로 밴드체(100)에 측정체(200)가 장착된 상태이라 해도 착용부위에서 흘러내리지 않게 되면 접촉부(210)의 단자(220)는 훈련프로그램이 완료될 때까지 접촉된 위치를 유지하여 측정값이 안정되게 수집될 수 있는 특징이 있다. In addition, since the surface of the contact band 130 has a curved concavo-convex shape, it makes the contact with the skin more stable, so that even when the measuring body 200 is attached to the band body 100, it does not flow down from the worn part. When the terminal 220 of the contact unit 210 maintains the contacted position until the training program is completed, the measurement value can be stably collected.
도 6은 본 발명의 밴드체에 대한 다른 실시 예 적용상태도이다.6 is a state diagram of another embodiment applied to the band body of the present invention.
