Description

Technical Field

[0001] The present invention relates to the technical field of medical assistive devices, and in particular to a walking aid for gait correction training of hemiplegic stroke patients. Background Art

[0002] Stroke has become a major factor leading to disability in Chinese people. It is predicted that with the increasing aging of my country, the number of people with hemiplegia after stroke will further increase. Hemiplegia has seriously affected the quality of life of patients and their families, and has led to rising social medical costs, bringing a heavy burden to individuals, families, and society. Helping hemiplegic patients recover basic motor functions and return to normal life is of great social significance. It is difficult for most hemiplegic patients to fully recover their functions. Although some patients can walk independently, their gait is abnormal. Abnormal gait will cause a series of secondary adverse effects on the patient's knee joints, spine and other body organs, thereby causing other physical diseases. At the same time, it will also have a negative impact on the patient's psychology, making it impossible for the patient to truly integrate into social life. Therefore, helping people with hemiplegia after stroke to carry out rehabilitation and walking training is a social problem that needs to be solved urgently.

[0003] Hemiplegic patients typically exhibit a typical hemiplegic gait, also known as a circular gait. When walking, the affected lower limb is affected by muscle weakness and spasms, forcing the patient to raise their hips and use their body's strength to lift their leg. They then swing their leg out to the side in an outward circular motion, bringing it forward. They then shift their weight onto the affected leg and move forward with their healthy leg. Gait training for hemiplegic patients is similar to how a baby learns to walk: It requires extensive, repetitive, and correct walking training to enable patients to walk smoothly again. Once a patient uses a hemiplegic gait for a long time, the abnormal movements become ingrained and difficult to correct. Gait training is a crucial component of rehabilitation for hemiplegic patients. Existing walking aids generally offer few features that assist with rehabilitation and can correct improper walking posture. However, correcting the hemiplegic gait is a crucial component of rehabilitation for hemiplegic patients.

[0004] Currently, the equipment used for lower limb rehabilitation training for hemiplegic patients primarily consists of two categories: standard walkers and rehabilitation robots. Standard walkers are inexpensive and easy to use, making them the preferred choice for most patients. However, since hemiplegic patients lack brain nerve signals to control the affected limb, the affected limb cannot exert force normally, thus failing to fundamentally correct the hemiplegic gait. Rehabilitation robots generally mechanically drive the patient to perform passive movements, and are very effective for patients in the early stages of stroke and bedridden patients in the acute phase. However, passive exercise training is far less effective than active exercise. Therefore, for hemiplegic patients in the recovery stage who have some walking ability, the effectiveness of rehabilitation robots is significantly reduced. More importantly, rehabilitation robots are expensive, unaffordable for the general population, and unsuitable for home rehabilitation needs.

[0005] Hemiplegic gait is primarily caused by muscle weakness and spasms. Muscle weakness is primarily due to damage to the corresponding motor control nerves in the brain, which prevent them from generating force signals, while the muscles themselves are not damaged. Muscle spasms are primarily caused by abnormal electrical discharges in the damaged brain. Functional electrical stimulation is a common rehabilitation method. It belongs to the category of neuromuscular electrical stimulation, a physical technique that uses pre-designed low-frequency pulse currents with specific waveforms, intensities, and repetition rates to stimulate specific muscle groups according to established procedures, inducing muscles to simulate normal voluntary movements or complete specific movements according to treatment plans. This can accelerate the process of neuroplasticity in stroke patients and gradually restore limb motor function. However, continuous stimulation during functional electrical stimulation can also lead to muscle fatigue, and overuse can lead to muscle damage. Furthermore, for hemiplegic patients, the muscle contraction force generated by functional electrical stimulation is relatively weak, unable to assist with voluntary movement, and poses significant control challenges.

[0006] Currently, to correct abnormal gait behavior in hemiplegic patients, they must be fitted with a specially shaped brace. This brace is bulky, making walking very strenuous, and inconvenient to put on and take off. Therefore, combining mechanical assistance with functional electrical stimulation for gait training can fully utilize the advantages of both, complementing each other and achieving optimal rehabilitation results. Summary of the Invention

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-6 As shown, a walking aid device for gait correction training of hemiplegic patients due to stroke includes: a supporting walking aid structure 1, a mechanical force conduction assist module 2, a functional electrical stimulation assist module 3 and a suspension weight reduction module 4; the supporting walking aid structure 1 includes a bracket 11 and a plurality of connecting rods, the bracket 11 and the connecting rods support and surround the hemiplegic patient due to stroke, provide safety support for the patient and assist the patient in walking, the mechanical force conduction assist module 2 is movably arranged on the supporting walking aid structure 1 and connects the healthy limb and the affected limb of the hemiplegic patient due to stroke, the healthy limb drives the affected limb through the mechanical force conduction assist module 2, the functional electrical stimulation assist module 3 is electrically connected to the mechanical force conduction assist module 2, the suspension weight reduction module 4 is arranged on the supporting walking aid structure 1, and the hemiplegic patient due to stroke wears the suspension weight reduction module 4.

[0030] The bracket 11 is detachable. The bracket 11 has two front support rods 111 and two rear support rods 112 with the same height. The front support rods 111 and the rear support rods 112 adopt a sleeve structure, which is convenient for adjusting the height and is suitable for people and patients of different heights. The height is level with the waist. The bottom of the front support rods 111 are equipped with universal wheels 113. The universal wheels 113 can give the walking aid a flexible steering function. The universal wheels 113 are provided with brake structures 1131, so that the patient can remain stationary when stopping training and will not move suddenly due to road conditions and other unexpected factors; the bottom of the rear support rods 112 are equipped with directional wheels 114. The directional wheels 114 allow the walking aid to maintain relative stability and increase safety. A first connecting rod 12 and a second connecting rod 13 are provided between the two front support rods 111, a third connecting rod 14 and a fourth connecting rod 15 are provided between the two rear support rods 112, and a fifth connecting rod 16 and a sixth connecting rod 17 are provided between the front support rod 111 and the rear support rod 112 on the left side, respectively. The fifth connecting rod 16 and the sixth connecting rod 17 and the front support rod 111 and the rear support rod 112 adopt an opening and closing structure, so that the patient can more conveniently enter the surround bracket 11. The front support rod 111 and the rear support rod 112 on the right side are provided with a first connecting rod 12 and a second connecting rod 13. There are respectively provided a seventh connecting rod 18 and an eighth connecting rod 19 between them. The first connecting rod 12, the third connecting rod 14, the fifth connecting rod 16 and the seventh connecting rod 18 are located at the same height, which is equivalent to the height of the knee joint. The second connecting rod 13 and the fourth connecting rod 15 are located at the same height. The sixth connecting rod 17 connects the front support rod 111 and the top of the rear support rod 112 on the left side. The eighth connecting rod 19 connects the front support rod 111 and the top of the rear support rod 112 on the right side. The sixth connecting rod 17 and the eighth connecting rod 19 are equivalent to the height of the hip joint. Two arm brackets 115 and two handles 116 are also symmetrically provided on the sixth connecting rod 17 and the eighth connecting rod 19, allowing the patient to place his arms on the arm brackets 115 with better comfort. There is a handle 116 in front of each arm bracket 115 for the patient to grasp in order to better control the body balance and forward direction.

[0031] The mechanical force conduction assist module 2 includes a first leg cuff 21, a second leg cuff 22, several pulleys and an elastic rope 28. The first pulley 23 is arranged on the third connecting rod 14, the second pulley 24 is arranged on the end of the seventh connecting rod 18 close to the third connecting rod 14, the third pulley 25 is arranged on the end of the seventh connecting rod 18 close to the first connecting rod 12, the fourth pulley 26 is arranged on the front support rod 111, and the fifth pulley 27 is arranged on the second connecting rod 13. One end of the elastic rope 28 is connected to the rear side of the first leg cuff 21 and passes through the first pulley 23, the second pulley 24, the third pulley 25, the fourth pulley 26 and the fifth pulley 27 in sequence. The other end of the elastic rope 28 is connected to the front side of the second leg cuff 22. A thin film stretch sensor 281 is provided on the elastic rope 28. The thin film stretch sensor 281 is electrically connected to the functional electrical stimulation assist module 3, and is used to sense the time points when the elastic rope 28 is stretched and released, and thereby trigger the functional electrical stimulation assist module 3. The connection between the elastic cord 28 and the first leg cuff 21 and the second leg cuff 22 is located above the knee joint, which can maximize the effect of the healthy lower limb exerting force and the affected limb receiving force. The elastic coefficient of the elastic cord 28 can be selected according to the patient's condition. Under the condition that it does not affect the patient's gait, the larger the elastic coefficient, the better the power-assisting effect. The first pulley 23 is located directly behind the healthy lower limb. When the healthy lower limb steps forward, it drives the first leg cuff 21 forward, thereby causing the elastic cord 28 to stretch. The tension of the elastic cord 28 is transmitted to the other end, i.e., the front side of the second leg cuff 22, through the pulley, thus generating tension on the right lower limb of the affected side. The fifth pulley 27 is located above the high crossbar in front and directly in front of the affected lower limb, at a height comparable to the hip joint. Since the second leg cuff 22 is located at the knee joint, the elastic cord 28 generates a pulling force on the affected lower limb, which is directed forward and upward, at an angle of approximately 45 degrees to the horizontal plane, helping the affected lower limb to lift and step forward, and the healthy limb drives the affected limb to actively move.

[0032] The functional electrical stimulation booster module 3 includes a signal processor 31, a stimulation electrode 32, an electrode communication cable 33, an electrical stimulation generator 34, and a signal connection line 35. The functional electrical stimulation booster module 3 is arranged on the bracket 11. The stimulation electrode 32 is electrically connected to the electrical stimulation generator 34 via the electrode communication cable 33. The electrical stimulation generator 34 is electrically connected to the signal processor 31 via the signal connection line 35. The signal processor 31 is electrically connected to the film stretch sensor 281. The signal processor 31 adjusts the pulse amplitude, pulse width, and frequency of the current. The stimulation electrode 32 acts on the quadriceps femoris of the patient's right leg. The signal processor 31 is loaded with a programming control algorithm for adjusting the current pulse signal parameters, which adjusts the pulse amplitude, pulse width, and frequency of the stimulation current to achieve regulation and control of the stimulation intensity and stimulation time of the patient's muscles. The signal processor 31 is triggered by the thin film stretch sensor 281 placed on the elastic rope 28; when the affected lower limb lifts the leg, the signal processor 31 is connected to the electric stimulation generator 34 through the signal connection line 35, generates a pulse signal and outputs it to the outside, which is transmitted to the stimulation electrode 32 through the electrode communication cable 33, thereby stimulating the quadriceps femoris on the right thigh of the affected side. The time when the thin film stretch sensor 281 sends the trigger signal is the moment when the elastic rope 28 begins to shorten, that is, the moment when the affected lower limb begins to move forward. According to the patient's reaction speed, an appropriate delay is added to the trigger time. The electric stimulation can partially replace the EEG signal during normal walking, causing muscle contraction and generating muscle torque, thereby making the thigh produce a stepping action.

[0033] The suspension weight-reduction module 4 includes a suspension bracket 41, an elastic cable 42, two hooks, and a load-bearing safety harness 44. The suspension weight-reduction module 4 is a detachable structure. The suspension bracket 41 is mounted on the sixth connecting rod 17 and the eighth connecting rod 19. The elastic cable 42 is mounted on the suspension bracket 41. Two hooks are symmetrically arranged on the elastic cable 42. The load-bearing safety harness 44 is attached to the hooks. The suspension weight-reduction module 4 reduces the force exerted by the body's weight on the legs, making walking training easier and further protecting the patient's safety. During gait training, the patient wears the load-bearing safety harness 44, which is connected to the hooks via the upper straps. The suspension bracket 41 has a hook-shaped structure at each end that can hold the safety harness and bear the body's weight. The load-bearing safety harness 44 can be worn on the patient to prevent the patient from falling. The elastic cable 42 can be adjusted according to the patient's condition to control the suspension weight-reduction structure's ability to bear the body's weight and the weight borne by the lower limbs.

[0034] Example 2:

[0035] The walking aid device of this embodiment is used for gait correction training of hemiplegic patients after stroke. The main structure is the same as that of the first embodiment, except that:

[0036] During the initial stages of training, patients' control is poor. The two universal wheels are replaced with directional wheels 114 to increase controllability during gait training. The elastic cord 28 is replaced with a spring and a non-elastic nylon cord. The spring is placed between the two nylon cord sections and attached to the seventh connecting rod 18. The spring's elastic coefficient can be selected based on the patient's specific condition. Compared to the elastic cord 28, a spring with a higher elastic coefficient offers greater controllability. A thin film stretch sensor 281 is placed in parallel with the spring, triggering the electrical stimulation device when the spring contracts.

[0037] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
