[0002] Stroke patients with hemiplegia often experience stiffness in the paralyzed area, making it difficult to maintain proper posture like a normal person. This paralysis often results in spastic postures. Spastic postures in stroke hemiplegia manifest as shoulder depression and retraction, elbow flexion, forearm pronation, wrist flexion, lower limb external rotation, knee extension, and foot drop and inversion, and are the most common sequelae of stroke.

[0003] Proper limb positioning is a temporary posture that prevents or counteracts spasticity, protects joints, preserves joint function as much as possible, and improves the basic quality of life for stroke patients with hemiplegia. Currently, clinical methods for maintaining proper limb positioning typically involve using pillows, bolsters, or buckwheat pillows to correct limb alignment. However, existing pillows, due to their inherent shape limitations, cannot be adjusted according to the patient's limb recovery progress, height, or weight, thus limiting their usability.

[0047] Among them, several fourth binding straps 303 are provided on the upper surface of the concave support body 31 located on the left and right sides of the arc groove 301, which are used to bind and connect the patient's limbs by the corresponding fourth binding straps 303 on both sides when the patient's limbs are placed in the arc groove 301, thereby further improving the firmness of the support and positioning.

[0048] Specifically, the convex support pad 4 includes a convex support body 41 and a second pad layer 42 fixed to the outer wall of the arc-shaped protrusion 401. The convex support body 41 can be made of plastic, thereby providing reliable support strength while minimizing the overall weight of the limb orthosis. The second pad layer 42 is made of cotton or memory foam to improve user comfort.

[0049] Among them, several sets of fifth tying straps 403 are provided on the left and right sides of the convex support body 41. Each set of fifth tying straps 403 is set along the front and rear ends respectively. When the patient's joint is placed on the convex support pad 4, it is tied and connected by the corresponding fifth tying straps 403, which further improves the firmness of the support positioning.

[0050] One end of each third binding strap 402 and each fifth bracing strap 403 is fixedly connected to the outer wall of the convex support 41. The second pad 42 is provided with perforations corresponding to each third binding strap 402 and each fifth bracing strap 403. The other end of each third binding strap 402 and each fifth bracing strap 403 extends outward through each perforation.

[0051] Furthermore, limiting blocks 43 can be set on the upper front and rear sides of the convex support 41 respectively. When the joint of the hemiplegic patient is placed on the arc-shaped protrusion 401 for support and positioning, the limiting blocks 43 can be used to position the joint on the left and right sides to prevent the joint from slipping.

[0052] It should be noted that the limb correction device for hemiplegic patients in this embodiment of the present invention can be made into different sizes such as large, medium and small according to actual use needs, so as to meet the use needs of patients of different heights and weights.
