Embodiment Construction
[0021] see Figure 1 to Figure 5 , The present invention is a method for precise positioning of FES signals for rehabilitation of stroke patients. In this embodiment, a stroke patient with hemiparalysis of the lower limbs is taken as an example, and the method is used in the rehabilitation treatment process for both legs.
[0022] This embodiment acts on the double-leg powered exoskeleton installed on the outside of the healthy side joint 1 and the affected side joint 2, and is also applicable to the dual-arm powered exoskeleton for unilateral rehabilitation; the powered exoskeleton includes built-in installation or external computer The installed rehabilitation system is preset with required algorithms and control programs. The powered exoskeleton is provided with three angle sensors 3 , multiple speed sensors, multiple FES electrode matrices 4 and a pressure sensor 5 .
[0023] The model of the pressure sensor 5 is FSR 402 pressure sensor (Interlink Electronics Company), whi...

The invention relates to the fields of biomedical engineering, computer technology, and communication, and specifically discloses a method for precise positioning of FES signals for rehabilitation of stroke patients. The motion data of the patient and the EMG signal data of the adjacent limbs are used to calculate the corresponding motion data of the joint on the affected side as well as the FES action time and action point. The signal precise positioning method of the present invention determines the functional electrical stimulation site and timing of the affected joint through the movement of the healthy joint of the patient, rather than through the experience of the rehabilitation practitioner; through the principle of time-delayed mirroring, each patient can get a suitable The electrical stimulation time and action position of the physical condition, the FES stimulation received by the patient makes the movement of the patient's disease close to the movement of the normal limbs, which can better improve the activation of mirror neurons in the brain and promote the recovery of the patient. To a certain extent, it helps stroke patients to correct their gait during rehabilitation.
Description
technical field [0001] The invention relates to the fields of biomedical engineering, computer technology and communication, and specifically discloses a method for precise positioning of FES signals of stroke patients. Background technique [0002] With the improvement of living standards and changes in fertility awareness, the problem of population aging is becoming more and more serious. Many elderly people are paralyzed due to stroke and other reasons, which makes life in their later years very inconvenient. Paralyzed patients after stroke can stimulate the plasticity of the brain through a large number of rehabilitation training, restore a certain amount of exercise ability, realize self-care, improve the quality of life, return to society to the greatest extent, and reduce the burden on their children and family members. At present, most of the lower limb rehabilitation training requires the therapist to detect the patient in real time and artificially correct the reha...
