Description

Technical Field

[0001] The utility model relates to the technical field of Parkinson's disease patient training, in particular to a freezing gait rehabilitation nursing trainer for Parkinson's disease patients. Background Art

[0002] Freezing of gait in Parkinson's patients is a sudden, temporary, and inability to move forward walking difficulty, which is manifested as a sudden stop or almost inability to move while walking. Rehabilitation care trainers are essential for freezing of gait in Parkinson's patients. It can improve patients' walking ability, improve their quality of life, and provide necessary support and guidance in a variety of ways.

[0003] After searching, the Chinese patent announcement number is: CN216456747U. The utility model discloses a self-triggering trainer for rehabilitation nursing training of frozen gait for patients with Parkinson's disease, which relates to the technical field of training for patients with Parkinson's disease. The patient's active training component accounts for a large proportion in the self-triggering training, which improves the connection between posture control and walking control during the startup process. The specific scheme is: including a walking channel, the walking channel includes a left walking path and a right walking path, the left walking path and the right walking path are in contact with each other and are relatively movable, and the bottom of the left walking path and the right walking path are respectively connected to the lifting components. When the patient steps on the left walking path and the right walking path, the lifting components drive the corresponding walking path to descend, and when the patient lifts one side of his foot, the walking path corresponding to the lifted foot returns to rise under the drive of the lifting components. The self-triggering trainer for rehabilitation nursing of frozen gait for patients with Parkinson's disease provided by the utility model can perform self-training on Parkinson's patients and gradually recover.

[0004] Although the specification of the above patent mentioned that "the left walking path 101 and the right walking path 102 are collectively referred to as the walking path, and left and right are relative words. For the convenience of explanation, they refer to the side where the patient's left foot and right foot walk; after the patient steps on the walking path, as the patient steps into one side of the walking path, the corresponding lifting component 2 drives the left walking path 101 to descend, and the descending stimulation promotes the lateral center of gravity transfer of the supporting leg, and then realizes the pneumatic step. The above embodiment can realize the patient's self-training, reduce the patient's dependence, and thus improve the effect of training. At the same time, the center of gravity transfer during the training process can greatly improve the fun of the training process", but the patient's feet cannot be fixed and the tightness cannot be adjusted during exercise.
