Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training device technology, specifically to an ankle joint rehabilitation training device. Background Technology

[0002] In the clinical treatment of ankle sprains, fractures, and other conditions, plaster casts or braces are crucial for ensuring proper bone healing. However, immobilization for more than three weeks can lead to soft tissue adhesions and joint capsule contractures, resulting in decreased joint mobility and muscle weakness due to disuse atrophy, severely impacting lower limb function. Therefore, after the removal of the immobilization device, systematic rehabilitation training becomes a key step in restoring function.

[0003] Currently, elastic band resistance training is widely used in clinical practice (see reference). Figure 6 As shown, patients typically fix one end of an elastic band to the sole of their foot and use their hand to pull the other end for resistance training. This effectively improves the strength of ankle muscles such as the gastrocnemius and soleus through isotonic contraction and dynamically adjusts the range of motion of the joint using elastic resistance. However, this training method has some drawbacks. The elastic band requires upper limb traction to generate resistance, making it difficult to achieve effective training for patients with upper limb dysfunction or elderly patients with muscle weakness. In addition, the measurement of joint range of motion relies on medical staff or family members using a goniometer, which patients cannot accurately measure independently.

[0004] Therefore, how to design an ankle joint rehabilitation training device that enables special patients to complete rehabilitation training and independently measure joint range of motion is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0005] Therefore, the technical problem to be solved by this invention is to overcome the fact that the elastic band resistance training in the prior art requires upper limb traction to provide resistance, which makes it difficult for elderly patients with upper limb dysfunction or weak muscle strength to perform effectively; in addition, the technical defect that patients cannot complete the measurement of joint range of motion on their own, so as to provide an ankle joint rehabilitation training device that enables special patients to complete rehabilitation training and independently complete the measurement of joint range of motion.

[0050] During ankle resistance training, the patient's leg is fixed within the leg fixation device 1, and the foot is secured to the foot pedal 2. After fixation, two first elastic bands 3 are installed on both sides of the leg fixation device 1 and the foot pedal 2, respectively. During training, the patient actively flexes and extends the ankle joint to drive the foot pedal 2 to rotate. Simultaneously, the first elastic bands 3 generate progressive resistance as their stretching length increases, creating favorable conditions for ankle muscle strength training and thereby enhancing the strength of the muscles surrounding the ankle joint. When performing flexion and extension movements, the range of motion of the joint can be intuitively grasped through measurement structures, allowing for precise control of the flexion and extension amplitude and ensuring that the target range of motion is achieved with each movement.

The pointer 52 is rotatably mounted on the measuring ruler 5. The indicator 53 is located on the side of the leg fixation member 1 near the measuring ruler 5. In the initial state, the indicator 53 indicates the 90° position of the angle scale line 51. During training, the pointer 52 is rotated to the target angle of the angle scale line 51, and then the foot pedal 2 is rotated by foot movement until the pointer 52 is aligned with the indicator 53, and the patient completes the target range of motion for training.

[0055] like Figure 3-5 As shown, the first elastic band 3 is detachably mounted on both sides of the leg fixing member 1 and the foot pedal 2 via a mounting structure; the mounting structure includes a first mounting member 6 and a second mounting member 62; wherein, there are two first mounting members 6, which are respectively mounted on both sides of the leg fixing member 1 and have a first mounting opening 61; one end of the first elastic band 3 can be installed into the first mounting member 6 through the first mounting opening 61; there are two second mounting members 62, which are respectively mounted on both sides of the foot pedal 2 and have a second mounting opening 63; the other end of the first elastic band 3 can be installed into the second mounting member 62 through the second mounting opening 63, thereby making the first elastic band 3 detachably mounted on both sides of the leg fixing member 1 and the foot pedal 2.

[0056] like Figure 5 As shown, the foot pedal 2 has a third mounting member 21 at its front end. The third mounting member 21 has a third mounting opening 22.

[0057] The leg fixation component 1 includes a main body 11 and fixing plates 12 disposed on both sides of the main body 11. The main body 11 has a concave arc surface, and the patient's leg is adapted to be placed in the concave arc surface. The foot pedal 2 is rotatably mounted on the bottom of the fixing plates 12 on both sides.

[0060] In this embodiment, the ankle joint rehabilitation training device is used as follows: When the patient is performing ankle joint resistance training, the leg is placed in the concave arc surface of the main body 11 and fixed in the leg fixing member 1 by the first left side fixing strap 71 and the first right side fixing strap 72. The foot is placed on the foot pad 23 and fixed in the foot pedal 2 by the second left side fixing strap 81 and the second right side fixing strap 82. After the fixation is completed, the patient selects a set of first elastic bands 3 with different tensions according to their actual situation and installs the set of first elastic bands 3 into the first mounting member 6 and the second mounting member 62 through the first mounting opening 61 and the second mounting opening 63 respectively. During training, rotate the pointer 52 to the target angle on the angle scale 51, and then actively flex and extend the ankle joint to drive the foot pedal 2 to rotate until the pointer 52 is aligned with the indicator 53, at which point the patient completes the target range of motion for training. When the patient needs to perform reverse ankle flexion and extension training, remove the first elastic band 3 and install the second elastic band 4 into the third mounting piece 21 through the third mounting opening 22. During training, rotate the pointer 52 to the target angle on the angle scale 51, and then actively flex and extend the ankle joint to drive the foot pedal 2 to rotate until the pointer 52 is aligned with the indicator 53, at which point the patient completes the target range of motion for training.
