[0002] Parkinson's disease, also often referred to as "Parkinson's paralysis," is a neurodegenerative disease. The main cause of this disease is the degeneration and death of dopaminergic neurons in the substantia nigra, which may be related to multiple factors such as genetics, environmental factors, and aging of the nervous system. It is generally recognized that aging is the most important factor in the occurrence of Parkinson's disease. The disease has a significant high incidence in the elderly, and the incidence rate in men is slightly higher than that in women.

[0003] For Parkinson's disease, physical rehabilitation intervention in the early stages can complement drug treatment to delay the course of the disease, and in the late stages it can prevent complications such as joint deformities, muscle atrophy and aspiration pneumonia caused by falls.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Parkinson's disease, also often referred to as "Parkinson's paralysis," is a neurodegenerative disease. The main cause of this disease is the degeneration and death of dopaminergic neurons in the substantia nigra, which may be related to multiple factors such as genetics, environmental factors, and aging of the nervous system. It is generally recognized that aging is the most important factor in the occurrence of Parkinson's disease. The disease has a significant high incidence in the elderly, and the incidence rate in men is slightly higher than that in women.

[0030] Medical research suggests that the occurrence of Parkinson's disease is related to the degeneration and death of dopaminergic neurons in the substantia nigra, but what exactly causes the degeneration and death of these neurons has not been clearly determined. It may be related to multiple factors, including genetic factors, environmental factors, and aging of the nervous system.

[0031] Genetic factors

[0032] It is currently believed that 10% of patients have a family history, and the vast majority of patients are sporadic.

[0033] Environmental factors

[0034] Industrial or agricultural toxins in the environment that have a similar molecular structure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), such as certain pesticides, herbicides, rotenone, etc., may be one of the causes of Parkinson's disease.

[0035] Aging of the nervous system

[0036] Data show that after the age of 30, as people age, the dopaminergic neurons in the substantia nigra begin to degenerate, but not all of them lead to Parkinson's disease. Aging is the most important factor in the occurrence of Parkinson's disease.

[0037] Multifactor interaction

[0038] In addition to gene mutations that cause a small number of familial Parkinson's disease patients, genetic susceptibility can increase the probability of disease, but it does not necessarily lead to disease. The combined effects of environmental factors, aging of the nervous system and other factors will lead to disease.

[0039] The symptoms of Parkinson's disease vary from person to person. The most obvious symptoms are resting tremor, bradykinesia and muscle rigidity. Patients in the middle and late stages will have postural balance disorders. Before and after the onset of the disease, there will also be some non-motor symptoms, including constipation, olfactory disorders, sleep disorders, autonomic dysfunction, and mental and cognitive disorders.

[0040] Motor symptoms

[0041] Resting tremor: This type of symptom is often the first symptom, mostly starting from the distal part of one upper limb, and appears or is obvious when the body is in a static position. When the disease occurs, there is a "pill-rolling" movement between the thumb and the flexed index finger.

[0042] Myotonia: The patient's limbs may appear similar to the bending of soft lead pipes, which is called "lead pipe rigidity"; in patients with static tremors, intermittent pauses may occur, like turning gears, which is called "gear rigidity". In severe cases, patients may have special flexed positions or postures, and may even be unable to take care of themselves.

[0043] Bradykinesia: In the early stages, it can be observed that the patient's fine finger movements are slow, such as unbuttoning or buttoning, tying shoelaces, etc., which is particularly obvious.

[0044] Postural balance disorder: It occurs in the middle and late stages of the disease, and is manifested by difficulty in standing up and easy falling backwards. Sometimes after the patient takes a step, he walks faster and faster with very small steps and cannot stop in time, which is called forward gait or panic gait.

[0045] Non-motor symptoms

[0046] Sensory impairment: Loss of sense of smell may occur in the early stage, and numbness and pain in the limbs may occur in the middle and late stages of the disease.

[0047] Sleep disorders: frequent dreams at night, accompanied by loud shouting and body movements.

[0048] Autonomic dysfunction: may be accompanied by constipation, sweating, urination disorders, orthostatic hypotension, etc.

[0049] Mental disorders: About 50% of patients suffer from depression, often accompanied by anxiety. In the late stage of the disease, about 15% to 30% of patients experience cognitive impairment or even dementia. The most common mental disorder is visual hallucinations, also known as visual hallucinations.

[0050] In the related art, a gait training device for Parkinson's disease patients includes a rectangular base plate, rectangular frames are symmetrically arranged on both sides of the rectangular base plate, and a strip opening is arranged in the middle of the rectangular base plate; the rectangular frame includes two columns, an upper horizontal rod arranged above the columns, and a lower horizontal rod arranged below the columns, and a slide groove is arranged on the upper end surface of the upper horizontal rod, and a sliding frame is arranged on the slide groove; the slide groove can pass through the entire upper horizontal rod or only the end is not opened. When the entire rod is passed through, baffles are required to block the two ends. The lower horizontal rod is located below the rectangular base plate. The sliding frame includes two top rods, and a slider that cooperates with the slide groove is arranged below the top rod. A vertical plate is arranged on the top rod on the outside of the slider, and a connecting plate is arranged on the inside of the vertical plate. One end of the two connecting plates is connected by a fixed support plate, and the other end is connected by a movable support plate. One end of the movable support plate is hinged on the connecting plate, and the other end is detachably connected to the other connecting plate; it can be connected by bolts or snaps, or a structure that realizes this function in the prior art can be used. It also includes several bottom baffles, and the bottom of the bottom baffle is provided with a clamping column that cooperates with the strip mouth. The clamping column can move linearly along the strip mouth, so that the distance between adjacent bottom baffles can be adjusted to adapt to patients with different physical conditions. The user can stand between the fixed support plate and the movable support plate, firstly to protect the patient, and secondly to support the patient when the patient performs gait training alone, and when the patient reaches the end, the patient only needs to turn around. Several connecting holes are provided on the vertical plate, and the connecting plate and the vertical plate are connected by bolts passing through the connecting holes. By adjusting the connecting plate, it can adapt to patients of different heights. A roller that cooperates with the slide is provided at the bottom of the slider. It is convenient for the patient to push the sliding frame while walking, and the roller does not need to be too sensitive. Since the patient needs to look straight ahead with both eyes and stand upright during gait training, the toes should be raised as much as possible when starting, and the heel should land first and then the toes should land. If only the fixed support plate and the movable support plate are used for support, the patient's body is easy to lean forward when performing gait training, affecting the training effect. Therefore, an arm support plate is provided on the inner side of the connecting plate. A connection groove is arranged in the middle of the upper end surface of the bottom baffle, and a plurality of movable baffles having the same structure and size as the bottom baffle are also provided. In this way, the movable baffles can be plugged into the bottom baffles, so that the height of the baffles can be adjusted according to the patient's condition, and the width of the baffles can also be adjusted, which is flexible and convenient to use.A rotating shaft is arranged between two columns located on the outer side of the rectangular bottom plate. The rotating shaft is arranged on the column through a bearing. A plurality of worms are arranged on the rotating shaft. A slot is arranged on the side of the rotating shaft. A connecting column is arranged on the inner side of the worm. The connecting column is arranged in the slot. A turbine meshing with the worm is also included. The turbine and the worm are self-locking. Fixed plates are arranged at both ends of the bottom baffle. Grooves matching the worm and the turbine are arranged on the side of the fixed plate. The rotating shaft passes through the groove and the worm and the turbine are arranged in the groove. The turbine is arranged in the groove through a bearing. A crank is arranged on the outer side of the turbine. The other end of the crank is hinged to one end of a rocker. The other end of the rocker is hinged to a mounting plate. The mounting plate is fixedly arranged on the column and is located below the rotating shaft. One end of the rotating shaft extends out of the column and is connected to a motor with a reducer through a transmission belt. The motor is arranged on a rectangular frame. The rotating shaft is respectively driven by a belt with the motor, and the parameters of the transmission belt and the pulley are the same. When the rotating shaft rotates, the worm rotates to drive the turbine to rotate, the turbine drives the crank to rotate, and the crank drives the rocker to swing. Driven by the rocker, the worm can move in a straight line along the slot, thereby pushing the fixed plate to move, so as to adjust the distance between adjacent bottom baffles. In this way, automatic control can be achieved, and the opening and closing of the motor is controlled by a remote control, which can adopt existing technology and will not be repeated here. A protective rod is arranged between the two rectangular frames, and the protective rod is arranged above the rotating shaft. The height of the bottom baffle and the movable baffle is 3cm-6cm. When the patient is trained, the height of the obstacle generally does not exceed 20cm. Both ends of the worm are in contact with the inner wall of the groove. The initial positions of adjacent cranks differ by 180°, and the number of cranks is an even number, at least 6, so that the intervals between adjacent bottom baffles can be minimized and maximized by adjusting the position of the cranks, and all intervals can be made consistent. When the cranks are in a vertical position, the intervals between all bottom baffles can be kept consistent, and when the cranks are in a horizontal position, the maximum and minimum intervals can be achieved. In general, only the minimum and equal intervals are required. The minimum interval is suitable for patients with small strides and poor physical strength. This can make the intervals between the bottom baffles smaller, and when stepping over two bottom baffles, there is enough space for the two feet to stand side by side and pause for a while before exercising. When the patient can adapt to a higher interval, all intervals can be adjusted to be consistent. An inclined plate is set between the rectangular bottom plate and the ground. The beneficial effects of this technology are: when the patient uses it, the sliding frame can be pushed by the fixed support plate and the movable support plate to repeatedly perform gait exercises, and the height of the fixed support plate and the movable support plate can be adjusted to adapt to patients of different heights. In order to ensure that the patient remains upright during exercise, an arm support plate is set. In addition, obstacles can be combined in the form of a bottom baffle and a movable baffle, and the height and width can be adjusted, and the intervals between obstacles can also be adjusted. Automatic control can be achieved by setting a rotating shaft, a crank and a rocker. Of course, the controller and remote control can be implemented using existing technologies.

The upper ends of the two oblique rods are respectively fixedly connected to the middle part of the lower side of the limit groove rod, and the two limit groove rods are respectively provided with limit rods, and the two limit rods are respectively fixedly connected to the lower end of the inverted U-shaped rod, and the two inverted U-shaped rods pass through the limit cross rod, and one end of the limit cross rod is fixedly connected to the vertical plate. One side of the upper ends of the two inverted U-shaped rods is respectively hinged to one end of the connecting rod, and the other ends of the two connecting rods are respectively hinged to the two horizontal axes in the middle of the rotating rod. One end of the rotating rod is fixedly connected to one end of the central axis of the rotating wheel. The center of the rotating wheel is fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the motor fixing block, and the motor fixing block is fixedly connected to the upper end of one side of the vertical plate. The beneficial effects of this technology are: (1) the device can exercise the legs of Parkinson's patients. The alternating swing of the foot pedal drives the patient's legs to swing alternately, which can assist the patient in leg exercise; (2) it assists the patient in swinging his legs to correct his gait. The patient's legs follow the movement of the foot pedal, which facilitates the correction of gait.

The top of the base plate is provided with a second slide groove matching the protective shell, and the protective shell is slidably connected to the top of the base plate through the second slide groove. The top of the protective shell is provided with a first slide groove matching the protective cover, and the protective cover is slidably connected to the top of the protective shell through the first slide groove. The top of the protective shell is provided with a first card slot, the top of the protective cover is provided with a card slot, the card slot penetrates the protective cover, and a card block matching the first card slot is clamped inside the card slot, and the position of the card block is symmetrical with the position of the first card slot. The telescopic assembly includes an electric push rod, the top of the bottom plate is threadedly connected with the electric push rod, and the left side of the electric push rod is fixedly connected to the right side of the protective shell.

Because the protective shell can slide left and right on the second slide groove, the patient can grasp the sponge pad and use the foot strength to slide the protective shell so as to perform rehabilitation training on the patient's gait. In the early stage of training, the user can turn on the electric push rod. Under the push and pull of the electric push rod, the sliding resistance of the protective shell can be greatly reduced, so that the patient does not need to use too much strength during training. When the patient adapts to the difficulty of training, the electric push rod can be removed, and then exercise by himself to increase the difficulty of training for the patient, thereby promoting rehabilitation training of the patient's gait.
