Lower-limb rehabilitation training device and control method thereof

Abstract

The invention discloses a lower-limb rehabilitation training device and a control method thereof. The device includes a machine frame, a control device, thigh bar components, crus bar components, first connection rods, second connection rods, third connection rods, an ankle joint component, a thigh bar supporting component, a second connection rod supporting component, a first motor push rod, a crus bar supporting component, a second motor push rod, and lower limb fixation components, wherein the thigh bar components, the crus bar components, the first connection rods, the second connection rods and the third connection rods are arranged on the two sides of the machine frame in pairs respectively, the thigh bar supporting component is arranged between the two thigh bar components, the second connection rod supporting component is arranged between the two second connection rods, the first motor push rod is installed between the thigh bar supporting component and the second connection rod supporting component, the crus bar supporting component is arranged between the two crus bar components, and a second motor push rod is installed between the crus bar supporting component and the ankle joint component, and the lower limb fixation components are installed on the thigh bar components and the crus bar components. The device overcomes the shortcoming that a traditional lower-limb rehabilitation device only provides passive training. Patients can do active rehabilitation training according to their activity intentions during rehabilitation intervention treatment by using the device, brain nerve remodeling is promoted, and the impaired function of the body is improved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation aids, in particular to a lower limb rehabilitation training device and a control method thereof. Background technique [0002] According to the "China Stroke Prevention Report (2018)" released on October 7, 2018, the incidence and prevalence of stroke in my country are still on the rise, and the disease burden of stroke is still increasing. About 60-80% of stroke survivors have disabilities of varying degrees, and severe cases even lose their ability to live a normal life. Clinical studies have shown that interventional rehabilitation can effectively improve limb mobility and return to normal life when patients are conscious, have no serious behavioral abnormalities, have stable vital signs, and have no complications. [0003] Traditional rehabilitation equipment, such as some limb training devices, the rehabilitation mode is mostly a single directional training, long-term use will cause n...

Problems solved by technology

[0003] Traditional rehabilitation equipment, such as some limb training devices, the rehabilitation mode is mostly a single directional training. Long-term use will cause negative effects such as resistance to the patient, affecting the rehabilitation effect, and the objects are often mild patients who can carry out active training. For patients who are severely disabled by stroke, passive rehabilitation training in the early stage is very important. At this stage, they basically rely on rehabilitation nurses for passive rehabilitation training. For the nurses themselves, the labor intensity is high and the cycle is long
