Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical and nursing technology, and in particular to an elastic band resistance training device. Background Technology
[0002] Difficulty swallowing is a common problem among older adults. Weakness and muscle loss of the swallowing muscles, including the tongue, suprahyoid (SH) muscle, and pharyngeal muscles, lead to decreased swallowing function.
[0003] The relationship between dysphagia and weakness or sarcopenia is interdependent. The presence of dysphagia, including malnutrition and aspiration pneumonia, can lead to the development of weakness and sarcopenia, while weakness and sarcopenia can cause dysphagia. Therefore, dysphagia rehabilitation should include swallowing assessment and recommend exercises for patients with age-related dysphagia to prevent aspiration pneumonia and improve swallowing function.
[0004] Okada's 320-ADCT study suggests that the stylohyoid, digastric, and mylohyoid muscles are involved in the upward movement of the hyoid bone. The geniohyoid muscle plays a major role in the forward movement of the hyoid bone.
[0005] Craniotropy ("chin-down" position) can improve laryngeal vestibule closure and reduce the risk of aspiration, while craniotropy extension ("pull-up" position) can delay hyoid bone elevation and increase the risk of pharyngeal residue and aspiration. Therefore, researchers have proposed the following training methods to improve symptoms in patients with dysphagia, including:
[0006] I. Shaker Practice
[0007] Shaker exercises are perhaps the most well-known training technique used in patients with dysphagia and impaired UES opening to improve pharyngeal elevation. Shaker exercises involve supine head lifting, including isometric and isokinetic movements daily for six weeks. The patient lifts their head, observing the toes and shoulders touching the ground. The isometric portion consists of three consecutive continuous head lifts, each lasting one minute, with a one-minute rest between each lift. The isokinetic portion consists of 30 consecutive head lifts in the same supine position. This head lifting exercise strengthens not only the suprahyoid (SH) muscle but also the thyrohyoid muscle. Application of this exercise in healthy older adults and tube-fed patients with severe dysphagia has shown improved pharyngeal elevation and a wider UES opening.
[0008] The disadvantage of this training method is that it has high requirements for body position and cannot be trained anytime and anywhere. In particular, it cannot be well used for patients with difficulty in body position transfer, such as those with stroke.
[0009] II. Jaw Opening Exercise (JOE) and Jaw Resistance Exercise (JOR) using a swallowing aid
[0010] Wada et al. reported a jaw opening exercise (JOE) for improving pharyngeal elevation and ureterosalpinx (UES) opening. JOE is an isometric exercise performed in a seated position, twice daily for four weeks. The protocol is as follows: First, subjects open their jaws to the maximum extent and hold that position for 10 seconds. During the exercise, each patient is aware of a strong contraction of the suprahyoid muscle (SH). This opening and holding exercise is performed 5 times, followed by a 10-second rest, constituting one set. Application of this exercise in patients with mild to moderate dysphagia improved hyoid elevation, UES width, and pharyngeal passage time.
[0011] Kraaijenga et al. developed a mandibular resistance (JOR) exercise using a swallowing motor aid, in which one device applies a load to the mandible to counteract mandibular opening and strengthen the suprahyoid muscle (SH). Application of JOR in healthy older adults improved mandibular opening strength and suprahyoid muscle (SH) volume.
[0012] Its advantage lies in the fact that the jaw can be opened while seated, allowing for simpler movements than lifting the head while lying down. The jaw opening action directly overloads the suprahyoid (SH) muscle, resulting in a good exercise effect. Its disadvantage is that patients with a history of temporomandibular joint arthritis should avoid using open jaw surgery for dysphagia rehabilitation due to excessive load on the temporomandibular joint.
[0013] III. CTAR Training
[0014] Method: The patient sits with an inflatable balloon placed between the manubrium of the sternum and the chin. The balloon is squeezed as much as possible. After completing 3 isometric CTAR exercises, 30 isometric CTAR exercises are performed. The isometric CTAR movement is held for 60 seconds, followed by a 60-second rest. This process is repeated 3 times.
[0015] Principle: CTAR training is a training model based on the Shaker training method. It is performed while seated and achieves good therapeutic effects. The treatment of dysphagia after stroke primarily utilizes mandibular adduction, which, through the active contraction of the neck extensor muscles, hyoid muscle, and suprahyoid muscle, causes the infrahyoid, thyrohyoid, and suprahyoid muscles to be pulled towards the sternum via the mandible. CTAR training uses the elasticity of a ball to improve the contractile ability of the supratonsillar muscle group, essentially the same as the Shaker training method. Its disadvantage is that the balloon is prone to bursting and difficult to secure.
[0016] Therefore, this invention proposes an elastic band resistance trainer to adapt to all people with swallowing disorders caused by muscle reduction or partial denervation of the suprahyoid muscles, to train the swallowing muscles and improve the patient's swallowing difficulties. Utility Model Content
[0017] The purpose of this invention is to provide an elastic band resistance trainer to help patients with swallowing difficulties train their swallowing muscle groups. It is highly adaptable, easy to use, and effectively improves swallowing difficulties.
[0018] The objective of this utility model is achieved through the following technical solution:
[0019] An elastic band resistance training device includes a first connecting buckle, a second connecting buckle, a third connecting buckle, and a fourth connecting buckle. Each of the first, second, third, and fourth connecting buckles has a connecting hole at its upper, lower, left, and right ends. A first headband is connected in series between the connecting holes at the left and right ends of the first, second, third, and fourth connecting buckles. One end of the first headband has a first hook and loop fastener with barbed edges, and the other end has a first hook and loop fastener with rough edges. The barbed edges can be glued and fixed to the rough edges. A second headband is fixed to the upper connecting hole of the first connecting buckle. The second headband has a second hook and loop fastener with barbed edges and rough edges. The barbed edges can pass through the upper connecting hole of the third connecting buckle and then fold over to be glued and fixed to the rough edges. A third headband is fixed to the upper connecting hole of the fourth connecting buckle. The third headband has a third hook and loop fastener with barbed edges and rough edges. The barbed edges can... After passing through the connecting hole at the upper end of the second connecting buckle, it is folded over and glued to the third hook and loop surface. The connecting hole at the lower end of the second connecting buckle is fixed with a first elastic band a. The end of the first elastic band a is fixedly connected with a first support plate. The connecting hole at the lower end of the third connecting buckle is fixedly connected with a first elastic band b. The first elastic band b is provided with a fourth hook and loop surface. The fourth hook and loop surface can pass through the first support plate and be folded over and glued to the fourth hook and loop surface. The connecting hole at the left end of the second connecting buckle is fixedly connected with a third elastic band a. The end of the third elastic band a is fixedly connected with a chest buckle. The connecting hole at the right end of the third connecting buckle is fixedly connected with a third elastic band b. The third elastic band b is provided with a sixth hook and loop surface. The third elastic band a and the third elastic band b can be stretched backward and crossed to pass through the user's armpit and extend forward. The sixth hook and loop surface can pass through the chest buckle and be folded over and glued to the sixth hook and loop surface.
[0020] In use, the second headband passes through the connecting hole at the upper end of the third connecting buckle, and the second hook and loop fastener is attached to the second hook and loop fastener. The third headband passes through the connecting hole at the upper end of the second connecting buckle, and the third hook and loop fastener is attached to the third hook and loop fastener. The first hook and loop fastener on the first headband is attached to the first hook and loop fastener, forming a cap-shaped structure, which is worn on the user's head. The first support plate is placed under the user's chin, the first elastic band b passes through the first support plate, and the fourth hook and loop fastener is attached to the fourth hook and loop fastener. The third elastic band a and the third elastic band b are stretched backward, cross from behind the user's shoulder, pass under the user's armpit, and extend forward to the chest. The sixth hook and loop fastener passes through the chest buckle and is folded over and attached to the sixth hook and loop fastener.
[0021] Users can perform jaw opening exercises (JOE) by using the tension of the first elastic band a and the first elastic band b. This exercise allows users to open their jaws to the maximum extent possible, thus strengthening the suprahyoid muscle (SH). This can improve the elevation of the hyoid bone, the width of the urethra, and the pharyngeal passage time. The first elastic band a and the first elastic band b provide resistance, applying a load to the jaw to counteract jaw opening and thus strengthen the suprahyoid muscle (SH). In healthy older adults, the application of mandibular resistance (JOR) exercises improved mandibular opening strength and suprahyoid muscle (SH) volume. Users can perform craniocervical extension exercises, i.e., Shaker exercises and CTAR training, using the tension of the third elastic bands a and b. The third elastic bands a and b provide tensile resistance mimicking the gravitational resistance of a supine head-lifting posture. Users can perform the supine head-lifting exercise of the Shaker exercise while seated and nodding, strengthening the suprahyoid (SH) and thyrohyoid muscles, achieving pharyngeal elevation and a wider UES opening. Alternatively, the third elastic bands a and b provide tensile resistance mimicking the elastic resistance of a CTAR training ball. Through the active contraction of the neck extensors, hyoid muscles, and suprahyoid (SH) muscles, the infrahyoid, thyrohyoid, and suprahyoid (SH) muscles are drawn towards the sternum via the mandible, improving the contractile ability of the suprahyoid (SH) muscle group. In addition, the third elastic band a and the third elastic band b can apply traction to the head of patients with head and neck weakness, which can maintain the head and neck in a neutral position, prevent the head from drooping and compressing the esophagus, and improve the safety of eating.
[0022] Preferably, a second elastic band a is fixed to the connecting hole at the lower end of the first connecting buckle, and a second support plate is fixedly connected to the end of the second elastic band a. A second elastic band b is fixedly connected to the connecting hole at the lower end of the fourth connecting buckle. The second elastic band b is provided with a fifth hook and loop surface and a fifth hook and loop surface. The fifth hook and loop surface can pass through the second support plate and be folded and pasted to the fifth hook and loop surface.
[0023] When in use, the second support plate is placed at the front of the user's chin. The second elastic band a and the second elastic band b can work together with the first elastic band a and the first elastic band b to perform jaw opening movement (JOE) and jaw resistance movement (JOR) to improve the resistance effect and connection stability.
[0024] For comfortable use and wearing, the first and second trays can be made of materials such as fabric or soft plastic.
[0025] The beneficial effects of this utility model are:
[0026] The aforementioned elastic band resistance trainer is easy to use and can be used anytime and anywhere. It can effectively train the user's swallowing muscles and improve the user's swallowing ability. Furthermore, the third elastic band a and the third elastic band b can apply traction to the head of patients with head and neck weakness, which can maintain the head and neck in a neutral position, prevent the head from drooping and compressing the esophagus, and improve the safety of eating. The trainer is easy to carry and uses Velcro connections, which can freely adjust the tightness of each connection point to suit people of different body types. The tension can also be adjusted to regulate the training intensity. Attached Figure Description
