Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation devices, and more specifically, to an upper limb mirror image rehabilitation training device for stroke patients. Background Art

[0002] In the early 20th century, clinical medical researchers generally believed that mirror therapy could activate the mirror neuron system, promote neuroplasticity and promote motor relearning. Mirror therapy requires a mirror box or a similar device that can hold a mirror. Mirror therapy uses such equipment and its use to create an optical illusion and allow stroke patients to replace the affected limb with the image of the healthy limb in the mirror. This visual feedback will induce the brain to perceive the movement of the affected limb, thereby improving the patient's motor control of the affected limb.

[0003] However, directly using the traditional single mirror method has poor effect on blocking the affected limb and poor training effect. The existing mirror rehabilitation training device for stroke usually uses camera imaging. This type of equipment is usually expensive and cannot be promoted and used in small and medium-sized hospitals, which in turn affects the recovery speed of related patients in nearby areas.

[0040] The reflection component provided in the present invention can reflect the movement state of the healthy limbs of the patient through multiple mirrors, so that the patient can perform mirror training in a sitting state in a top-down manner. The device does not use a camera for image acquisition and related equipment for image processing, which greatly reduces the manufacturing cost of the device, and at the same time avoids the influence of image transmission delay on the movement of the healthy limbs observed by the patient, thereby improving the training effect of the device. When using the device for mirror training, first unfold the support component in the storage component, and after fixing the state of the support component by the fixing component, let the patient maintain a sitting position, adjust the height of the telescopic rod 23, so that the patient's legs are respectively located in the two grooves 17, and at this time let the patient put both arms into the two arm sleeves 1 at the same time. When the patient is too small to completely put both hands into the grooves 17 along the arm sleeve 1, the patient's arms The protective plate 2 will be squeezed to rotate along the connecting axis between the protective plate 2 and the arm sleeve 1 and compress the coil spring. At the same time, when the patient's hands pass through the through hole opened in the middle of the folding gasket ring 11, the patient's arms will squeeze the two folding gasket rings 11 outward, and at the same time, the folding gasket rings 11 will be covered on the outside of the patient's arms to prevent external light from affecting the imaging. After the patient places the healthy arm into the sealed cavity 10 set in the box body 4, the movement of the patient's healthy hand will be displayed on the first reflector 14 through the light-transmitting plate 13, and then reflected by the first reflector 14 to the second reflector 12 opposite to it. The second reflector 12 will reflect the image through the one-way mirror 18 to the third reflector 19. The patient can directly observe the image reflected on the third reflector 19 from above, so that the patient can observe the movement of the healthy hand above the affected hand, thereby helping the patient to perform mirror training.
