Description

Technical Field

[0001] The present invention relates to the technical field of gait correction, and in particular to a gait recognition and correction system and method. Background Art

[0002] Gait recognition and correction is mainly aimed at individuals, especially children, who have abnormal gait due to various reasons. Through professional evaluation and correction methods, we help them improve their gait and improve their quality of life. Abnormal gait may be caused by many reasons, including but not limited to: Central nervous system damage: such as stroke, hemiplegia after brain trauma, cerebral palsy, etc. Bone and joint diseases and trauma: such as amputation, hip or knee replacement, arthritis, etc. Lower limb muscle strength damage: such as poliomyelitis, femoral nerve injury, etc. Physiological abnormalities of muscles or bones: such as O-legs, flat feet, etc.

[0003] Existing technologies, such as the invention of a gait recognition and correction method and system based on deep learning, have been granted the publication number CN117011944B. According to the abnormal walking gait, a corresponding correction method is designed, and the effect of the designed correction method is evaluated. By extracting the features of key nodes, the constraints of a healthy gait are formulated, the abnormal images and abnormal positions are accurately determined, a gait correction plan is formulated, and the correction effect is re-evaluated and adjusted regularly.

[0004] At present, there is still a lack of a correction system that can determine whether the gait is abnormal by monitoring the direction of the toes, the landing of the toes and heels, and the direction of the calf. By using correction rollers and rear correction plates to assist in correcting the calf, the heel is forced downward to maintain the correct posture.

[0005] Therefore, in view of the above problems, a gait recognition and correction system and method are proposed to solve the above problems. Summary of the invention

According to the direction of the calf deflection, the motor is controlled to rotate in the opposite direction, such as Figure 5 As shown, the calf deflects inward, that is, it deflects clockwise, causing the rotating ring to rotate counterclockwise. Due to the meshing of the gear ring, the front gear rotates counterclockwise, causing the correction roller to swing counterclockwise around the center of the front gear, and the correction roller rotates counterclockwise around the center of the support ring and swings counterclockwise around the center of the front gear at the same time. The two counterclockwise swings work together to make the left correction roller contact the hard position of the front part of the calf, while the right correction roller is away from the calf, making it easier for the calf to adjust its posture.

The rear correction plate 46 contacts the muscles of the back of the leg, driving the calf to deflect in the opposite direction to achieve calf correction. The rear correction plate 46 and the correction roller 45 move downward, clamping the calf and moving it downward, so that the heel touches the ground.

[0044] The distance measuring sensor 21 of the device measures the distance with the correction shoe 31.

[0045] The device controls the motor 61 to rotate in the opposite direction according to the direction in which the lower leg deflects. Figure 5 As shown, the calf deflects inward, that is, it deflects clockwise, causing the rotating ring 49 to rotate counterclockwise. Due to the meshing of the gear ring, the front gear 41 rotates counterclockwise, causing the correction roller 45 to swing counterclockwise around the center of the front gear 41, and the correction roller 45 rotates counterclockwise around the center of the support ring 52 and swings counterclockwise around the center of the front gear 41. The two counterclockwise swings work together to make the left correction roller 45 contact the hard position of the front of the calf, while the right correction roller 45 is away from the calf. By using the spring 47, when the rear correction plate 413 deflects, under the elastic action of the spring 47, the rear correction plate 413 moves toward the calf and contacts the calf, thereby assisting the calf in correcting its posture. When the rotating ring 49 rotates, the ball 412 moves downward along the semicircular groove 55, causing the correction roller 45 and the rear correction plate 413 to move downward, driving the calf downward, causing the heel to contact the sole, and achieving heel correction.

Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
