Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation appliances, in particular to a gait rehabilitation device. Background Art

[0002] Parkinson's disease is a degenerative disorder affecting the central nervous system. Clinically, it presents with typical motor symptoms, with prominent gait abnormalities. Freezing of gait is a common pathological gait pattern in Parkinson's disease, often manifesting as paroxysmal freezing inability to walk, inability to take the first step, or sudden inability to move forward while walking. Patients experience a sensation of their feet being glued to or sucked into the floor, making it difficult to lift their feet and take steps. Walking can take several seconds or even minutes, and some patients experience a degree of leg tremor. Freezing of gait significantly impacts patients' daily lives. In severe cases, it can lead to falls, fractures, loss of independence, and even death.

[0003] Currently, rehabilitation training is an important auxiliary measure for the treatment of freezing of gait in patients with Parkinson's disease, especially for patients with freezing of gait who do not respond well to drug treatment.

[0004] Most existing freezing gait rehabilitation training devices use kicking training. For example, publication number CN215274324U discloses a freezing gait rehabilitation training device for Parkinson's patients. This patent uses a movable rod that can slide within a sleeve to adjust the position of the training ball, and the position of the movable rod can be limited by an adjusting bolt. This facilitates kicking training for the feet of Parkinson's patients with different degrees of disease, improving the effectiveness of rehabilitation training for Parkinson's patients. However, this patent has the following defects:

[0005] This patent combines a ball-kicking device with a walker. The stand of the walker will interfere with the ball-kicking action during pace training, making it difficult to judge whether the pace training is in place.

[0006] In addition, the device takes up a large space and is not convenient for storage. Utility Model Content

The present invention secures the counterweight seat at a designated position, rotates the support arm via an angle adjustment assembly, and the rotation of the rotating shaft drives the winding roller to rotate, thereby paying out the traction line until the kicking ball is placed at an appropriate height. A medical worker assists the patient, who holds the support rod with one hand and the support arm with the other, then lifts their foot and kicks it onto the kicking ball. After one foot completes the kicking training, the patient lowers the foot and uses it as a support foot, then lifts the other foot and kicks it onto the kicking ball, repeating this action. After the patient successfully kicks the ball, a tactile stimulation is provided, allowing the patient to intuitively sense the training effect. Even if the kick misses, the patient can adjust the height of the next leg lift based on perception. This allows caregivers to intuitively determine whether the Parkinson's disease patient's rehabilitation training has met the required standards. During this period, the support arm's height can be adjusted via the angle adjustment assembly to accommodate patients of different heights, facilitating rehabilitation training for Parkinson's disease freezing gait and accurately and intuitively determining whether gait training is effective.
