Description

족저근막염 안창plantar fasciitis insoles
본 발명은 족저근막염 안창에 관한 것으로서, 보다 상세하게는 족저근막염 환자의 통증을 경감시키고 증상을 완화시킬 수 있는 안창에 관한 것이다.The present invention relates to an insole for plantar fasciitis, and more particularly, to an insole capable of alleviating pain and alleviating symptoms of plantar fasciitis patients.
발은 몸을 지지해주고 운동할 수 있게 해주는 역할을 한다. 따라서 발은 몸무게를 지탱할 뿐 아니라 움직일 때의 추진력을 전달해야 하기 때문에 탄력성과 신축성이 요구된다. 이러한 발의 탄력성과 신축성에 크게 관련되는 것은 족궁(足弓)이며 이 족궁중 내측 종족궁을 감싸고 있는 근막이 족저근막이다.Your feet support your body and allow you to move. Therefore, elasticity and elasticity are required because the foot must not only support the weight but also transmit propulsion during movement. The most important factor in the elasticity and elasticity of the foot is the foot arch, and among these arches, the fascia surrounding the medial arch is the plantar fascia.
발바닥에 우묵하게 들어간 것을 족궁(足弓)(arch)이라 하는데, 도 1의 (b)에 도시된 바와 같이 우리의 발은 세개의 족궁, 즉 내측 종족궁(縱足弓)(medial longitudinal arch), 외측 종족궁(lat.longitudinal arch), 횡족궁(橫足弓)을 가지고 있다. 이 세개의 족궁 중, 몸의 정중부에 가까운 것을 내측 종족궁, 먼것을 외측 종족궁이라 하며, 발등부위의 5개의 중족골이 이루는 족궁을 횡족궁이라고 한다.The one that enters the sole of the foot is called an arch, and as shown in Fig. 1 (b), our feet have three arches, that is, the medial longitudinal arch. , has a lat.longitudinal arch, and a transverse arch. Of these three foot arches, the one near the midline of the body is called the medial arch, the one farther away is called the outer arch, and the arch formed by the five metatarsal bones on the instep is called the cross foot.
이 족궁들은 보행시 쿠션과 같은 역할을 하여 충격을 흡수한다. 특히, 족저근막(Plantar Fascia)은 내측 종족궁을 정적으로 보강하는 두꺼운 막으로 종골의 내측돌기부분에서 시작되어 종(慫)으로 발앞부분에 부착되는데, 달리기, 점프등에서의 착지로 퍼졌다가 다시 수축하면서 착지의 충격을 흡수하는 역할을 한다. 족저근막은 달리기에서 착지직후의 발의 내전(뒤꿈치뼈가 안쪽으로 기울어지는 현상)과 동시에 부담을 받게 된다.These arches act as cushions when walking and absorb shocks. In particular, the plantar fascia is a thick membrane that statically reinforces the medial arch. It begins at the medial protrusion of the calcaneus and is attached to the forefoot as a bell. It serves to absorb the impact of landing. In running, the plantar fascia is strained at the same time as the pronation of the foot (the phenomenon in which the heel bone is tilted inward) immediately after landing.
족저근막염은 족저근막을 지나치게 사용함으로 인한 염증을 말한다. 다시말해, 족저근막염이란 내측 종족궁 부위의 발바닥 근육을 보호하는 근막인 족저근막에 과도한 충격이나 압박에 의하여 염증이 발생되며 심한 통증을 유발하는 발질환이다. 족저근막염은 선천적인 요족(종족궁이 높은발)이나 평발, 과체중이나 비만인 사람, 하이힐을 많이 신는 여성, 오래 달리거나, 점프를 많이 하는 운동선수(마라톤, 농구선수등)에게 많이 발생이 되며 일반인들도 최근 달리기 동호회 등을 중심으로 많이 늘고 있는 추세이다.Plantar fasciitis is inflammation caused by overuse of the plantar fascia. In other words, plantar fasciitis is a foot disease in which the plantar fascia, which is the fascia that protects the plantar muscle in the medial arch area, is inflamed due to excessive impact or pressure and causes severe pain. Plantar fasciitis occurs more frequently in congenital lumbago (foot with high arch), flat feet, overweight or obese people, women who wear high heels a lot, and athletes who run for a long time or jump a lot (marathon, basketball players, etc.) Also, it is a trend that has been increasing a lot recently, especially with running clubs.
따라서 족저근막염환자의 생체역학적인 분석에 의하여, 족저근막에 가해지는 압력이나 압박을 줄여 통증 및 피로를 감소시키는 족저근막염용 안창이 요구된다.Therefore, there is a need for an insole for plantar fasciitis that reduces pain and fatigue by reducing pressure or pressure applied to the plantar fascia by biomechanical analysis of plantar fasciitis patients.
본 발명은 보행 시 족저근막의 스트레칭 효과를 얻을 수 있는 안창을 제공한다.The present invention provides an insole capable of obtaining a stretching effect of the plantar fascia during walking.

본 실시예에 따른 족저근막염 안창(100)은 인솔바디부(110)와 제1 내지 제3 가압돌기(111, 112, 113)을 구비한다.The plantar fasciitis insole 100 according to the present embodiment includes an insole body part 110 and first to third pressing protrusions 111 , 112 , and 113 .
인솔바디부(110)는 인체의 발에 착용되는 신발의 접촉면을 형성한다. 본 발명에서의 인솔바디부(110)는 단순히 운동화의 외형을 형성하는 갑피 내에 구비되어 쿠션을 제공하는 인솔 뿐 아니라 샌들, 슬리퍼 등과 같은 신발류에 구비되어 인체의 발과 접촉면을 형성하는 부재를 통칭하는 개념이다.The insole body part 110 forms a contact surface of a shoe worn on a human foot. In the present invention, the insole body part 110 is provided not only in the insole that is provided in the upper that simply forms the outer shape of the running shoe and provides cushioning, but also in footwear such as sandals and slippers, which collectively refers to a member that forms a contact surface with the foot of the human body. Concept.
제1 내지 제3 가압돌기(111, 112, 113)는 인솔바디부(110)의 상부면에 종방향으로 배열되도록 구비된다. 제1 내지 제3 가압돌기(111, 112, 113)는 인솔바디부(110)의 상부면 중 인체의 횡족궁, 내측종족궁 및 외측종족궁으로 이어지는 영역에 대응하는 영역 내에 돌출 형성되고, 특히 제1 내지 제3 가압돌기(111, 112, 113)의 중심을 잇는 가상의 선이 도 1의 내측 종족궁에 인접하도록 구비된다. 특히, 인체의 중앙측으로부터 제1 가압돌기(111)와 제3 가압돌기(113)의 시작지점까지의 횡방향 길이는 중앙측으로부터 인솔바디부(110)의 외측 단부까지의 전체 횡방향 길이에 비하여 16% 내지 20%의 지점에 위치하는 것이 바람직하다. 스트레칭의 효과를 극대화하기 위하여 제1 가압돌기(111)와 제3 가압돌기(113)이 지지하는 위치가 중요하다. 이 때 제1 내지 제3 가압돌기(111, 112, 113)는 전방으로부터 후방을 향하여 종방향으로 형성된다.The first to third pressing protrusions 111 , 112 , 113 are provided to be arranged in the longitudinal direction on the upper surface of the insole body part 110 . The first to third pressing protrusions 111 , 112 , and 113 are formed to protrude in the region corresponding to the region leading to the transverse arch of the human body, the medial arch and the lateral arch of the upper surface of the insole body part 110 , and in particular An imaginary line connecting the centers of the first to third pressing protrusions 111 , 112 , 113 is provided adjacent to the inner arch of FIG. 1 . In particular, the lateral length from the central side of the human body to the starting point of the first pressing protrusion 111 and the third pressing protrusion 113 is the total lateral length from the central side to the outer end of the insole body part 110 . It is preferably located at a point of 16% to 20% compared to that. In order to maximize the effect of stretching, the positions supported by the first pressing protrusion 111 and the third pressing protrusion 113 are important. At this time, the first to third pressing projections (111, 112, 113) are formed in the longitudinal direction from the front toward the rear.
제1 내지 제3 가압돌기(111, 112, 113)는 다양한 형상으로 형성될 수 있으나, 횡단면이 원 및 타원 중 어느 하나인 원통형으로 형성되거나, 반구형으로 형성될 수 있다. 도 3의 하단에 도시된 바와 같이 원통형 몸체에 구형의 상부형상을 가진 타입(T1)이나, 원통형 몸체에 모따기가 된 형상을 갖는 타입(T2)이나 반구형의 형상인 타입(T3) 등 다양하게 형성 될 수 있다.The first to third pressing protrusions 111 , 112 , and 113 may be formed in various shapes, but may be formed in a cylindrical shape having a cross section of any one of a circle and an ellipse, or may be formed in a hemispherical shape. As shown in the lower part of FIG. 3, the cylindrical body has a spherical upper shape (T1), the cylindrical body has a chamfered shape (T2), and the hemispherical type (T3) is formed in various ways. can be
제1 내지 제3 가압돌기(111, 112, 113)는 앞서 설명한 바와 같이 인체의 발바닥 중 내측종족궁에 인접한 지점을 가압하여 스트레칭을 시켜주기 위한 구성부이다. 따라서 구성면에서 제1 내지 제3 가압돌기(111, 112, 113)의 직경 및 높이 이외에도 제1 가압돌기(111)의 전방으로부터의 시작위치, 제3 가압돌기(113)의 후방으로부터의 시작위치도 중요하다.The first to third pressing protrusions 111 , 112 , and 113 are components for stretching by pressing a point adjacent to the medial arch of the sole of the human body as described above. Therefore, in addition to the diameter and height of the first to third pressing projections 111, 112, and 113 in terms of configuration, the starting position from the front of the first pressing projection 111 and the starting position from the rear of the third pressing projection 113 are also It is important.
제1 내지 제3 가압돌기(111, 112, 113)의 직경은 20mm 내지 25mm이며, 제1 내지 제3 가압돌기(111, 112, 113)의 높이는 7.5 mm 내지 8.5 mm이고, 상기 제2 가압돌기의 높이는 9.5mm 내지 10.5mm로 형성된다.The first to third pressing projections (111, 112, 113) have a diameter of 20 mm to 25 mm, and the height of the first to third pressing projections (111, 112, 113) is 7.5 mm to 8.5 mm, and the second pressing projections The height of the is formed from 9.5mm to 10.5mm.
제1 내지 제3 가압돌기(111, 112, 113)의 직경이 20mm 보다 작은 경우에는 족저근막의 특정 지점이 과도하게 압박됨으로써 스트레칭의 효과보다는 통증이 증가되는 원인이 될 수 있으며, 25mm 보다 큰 경우에는 족저근막의 특정 지점을 지지하여 스트레칭을 시키는 효과가 떨어지는 것을 알 수 있었다. 마찬가지로 제1 내지 제3 가압돌기(111, 112, 113)의 높이가 7.5 mm 이하인 경우에는 발바닥의 족궁을 지지하지 못하여 스트레칭의 효과가 떨어졌으며, 8.5 mm 초과하는 경우에는 통증이 유발될 뿐 아니라 이물감이 과도하게 느껴지는 문제가 발생하였다. 이러한 두께의 특징은 제2 가압돌기(112)의 경우에도 마찬가지인 것을 알 수 있었다.When the diameter of the first to third pressing protrusions 111, 112, and 113 is smaller than 20 mm, a specific point of the plantar fascia is excessively compressed, which may cause an increase in pain rather than an effect of stretching. It was found that the effect of stretching by supporting a specific point of the plantar fascia was decreased. Similarly, when the height of the first to third pressing protrusions 111, 112, and 113 is 7.5 mm or less, the effect of stretching is reduced because the arch of the sole cannot be supported. This over-feeling problem occurred. It was found that the characteristic of this thickness is the same even in the case of the second pressing protrusion 112 .
전방으로부터 상기 제1 가압돌기(111)가 시작되는 위치는 인솔바디부(110)의 전체 길이에 비하여 35% 내지 40% 지점이고, 후방으로부터 제3 가압돌기(113)가 시작되는 위치는 인솔바디부(110)의 전체 길이에 비하여 27% 내지 30%인 지점인 것이 바람직하다.The position where the first pressing protrusion 111 starts from the front is 35% to 40% of the total length of the insole body part 110, and the position where the third pressing protrusion 113 starts from the rear is the insole body part 110. It is preferable that the point is 27% to 30% of the total length of the part 110 .
본 발명에 따른 제1 가압돌기(111) 내지 제3 가압돌기(113)들의 경도는 35 ± 5 shore A 정도가 적당하다. 경도가 너무 낮은 경우 제1 가압돌기(111) 내지 제3 가압돌기(113)에 의한 효과가 과도하게 저하되며, 경도가 너무 높은 경우에는 이물감이 과도하게 느껴지게 되어 착용감이 저하된다.The hardness of the first pressing projection 111 to the third pressing projection 113 according to the present invention is about 35 ± 5 shore A is suitable. When the hardness is too low, the effect by the first pressing protrusion 111 to the third pressing protrusion 113 is excessively reduced, and when the hardness is too high, a foreign body feeling is excessively felt, thereby reducing the wearing comfort.
일반적으로 보행주기는 발 뒤꿈치 접지기(Heel Contact Phase), 발바닥 접지기(Foot Flat Phase), 발뒤꿈치 들림기(Heel Off Phase), 발가락 들림기 (Propulsion, Toe Off Phase), 유각기(Swing Phase), 다시 발 뒤꿈치 접지기의 순서로 이어지게 되며, 이러한 보행 주기별로 나타나는 발의 동작에 대해서 발뒤꿈치 접지기에서는 회외전(supination)에서부터 회내전(pronation)이 일어나고, 발뒤꿈치 들림기가 시작되는 순간에 회외전이 일어나며 발가락 들림기에서 발가락이 지면을 밀치고 전진을 하게 되는 것으로, 우리의 발은 이러한 동작을 반복하게 된다.In general, the gait cycle includes heel contact phase, foot flat phase, heel off phase, propulsion, toe off phase, swing phase, It is followed again in the order of the heel-folding phase, and in the heel-folding phase, supination to pronation occurs, and supination occurs at the moment when the heel-lifting phase starts, with respect to the movement of the foot in each gait cycle. In the lift phase, the toes push the ground and move forward, and our feet repeat these movements.
보행시 혹은 기립시 발생하는 후족부의 회외는 내측종족궁의 긴장 및 피로도를 증가시켜 족저 근막염을 유발하게 되는데 이때 가압돌기가 내측종족궁을 받쳐 주고 압력을 가함으로서 족저 근막의 긴장도가 감소하게 된다. 이는 전접촉 안창이 보이는 내측족저궁 받침 역할보다 더 효과적이어서, 족저 근막염에 의한 발의 기능 손상으로부터 더 빠르게 환자를 회복시키는 것으로 나타났다.The supination of the hindfoot that occurs during walking or standing increases the tension and fatigue of the medial arch, leading to plantar fasciitis. This was shown to be more effective than the role of medial plantar arch support seen by the all-contact insole, resulting in faster patient recovery from plantar fasciitis-induced damage to the foot.
도 4 및 도 5를 참조하여 다른 실시예에 따른 족저근막염 안창을 설명한다. 도 4 및 도 5는 각각 다른 실시예에 따른 족저근막염 안창의 모습을 나타내는 개략도이다.A plantar fasciitis insole according to another embodiment will be described with reference to FIGS. 4 and 5 . 4 and 5 are schematic views showing the appearance of plantar fasciitis insoles according to different embodiments, respectively.
한편, 도 4에 도시된 바와 같이 제1 가압돌기(111a)와 제3 가압돌기(113a)는 각각 전후방으로 기울기를 갖도록 형성될 수 있다.Meanwhile, as shown in FIG. 4 , the first pressing protrusion 111a and the third pressing protrusion 113a may be formed to have an inclination in front and rear, respectively.
제1 가압돌기(111a)는 수직 방향의 가상의 선(Lv)에 대하여 일정한 기울기를 갖도록 전방으로 기울어지도록 형성되고, 제3 가압돌기(113a)는 수직 방향의 가상의 선(Lv)에 대하여 일정한 기울기를 갖도록 후방으로 기울어지도록 형성된다. 이 경우 족저근막염 환자가 이와 같인 안창이 구비된 신발을 착용하고 보행하는 경우 제1 가압돌기(111a)와 제3 가압돌기(113a)가 지지하는 지점의 사이를 확장시키는 효과를 얻을 수 있기 때문에 스트레칭의 효과를 더욱 증가시킬 수 있다.The first pressing protrusion 111a is inclined forward to have a constant inclination with respect to the imaginary line Lv in the vertical direction, and the third pressing protrusion 113a is formed to be inclined forward with respect to the imaginary line Lv in the vertical direction. It is formed so as to be inclined backward to have an inclination. In this case, when a patient with plantar fasciitis walks wearing shoes equipped with such an insole, the effect of expanding the space between the points supported by the first pressing protrusion 111a and the third pressing protrusion 113a can be obtained. The effect can be further increased.
다른 한편, 도 5에 도시된 바와 같이 제1 에어갭(1111)과 제2 에어갭(1131)을 구비하여 유사한 효과를 얻을 수 있다.On the other hand, as shown in FIG. 5 , a similar effect can be obtained by providing the first air gap 1111 and the second air gap 1131 .
제1 가압돌기(111b)에는 전방으로 갈수록 두께가 증가되는 제1 에어갭(1111)이 구비되고, 제3 가압돌기(113b)에는 후방으로 갈수록 두께가 증가되는 제2 에어갭(1131)이 구비될 수 있다. 발바닥에 의하여 제1 가압돌기(111b)와 제3 가압돌기(113b)가 가압되는 경우 제1 에어갭(1111)과 제2 에어갭(1131)의 두께의 차이로 인하여 제1 가압돌기(111b)와 제3 가압돌기(113b)가 각각 전방 및 후방으로 기울어지는 효과를 얻을 수 있다. 따라서 보행 시 도 4의 실시예와 유사하게 스트레칭을 강화시키는 효과를 얻을 수 있다.The first pressure protrusion 111b is provided with a first air gap 1111 that increases in thickness toward the front, and the third pressure protrusion 113b has a second air gap 1131 that increases in thickness toward the rear. can be When the first pressing protrusion 111b and the third pressing protrusion 113b are pressed by the sole, the first pressing protrusion 111b due to the difference in thickness between the first air gap 1111 and the second air gap 1131 and the third pressing protrusion 113b can obtain the effect of being inclined forward and backward, respectively. Therefore, it is possible to obtain the effect of strengthening the stretching similar to the embodiment of Figure 4 when walking.
이상 본 발명의 바람직한 실시예에 대하여 설명하였으나, 본 발명의 기술적 사상이 상술한 바람직한 실시예에 한정되는 것은 아니며, 특허청구범위에 구체화된 본 발명의 기술적 사상을 벗어나지 않는 범주에서 다양하게 구현될 수 있다.Although the preferred embodiment of the present invention has been described above, the technical spirit of the present invention is not limited to the above-described preferred embodiment, and can be implemented in various ways without departing from the technical spirit of the present invention embodied in the claims. have.
