Abstract

The invention relates to a double-electrode electronic system for reconstructing a gait motion function. The double-electrode electronic system comprises an instruction acquisition system, a pulse signal generation system, two biological stimulation electrodes and a reference electrode. The instruction acquisition system generates a control instruction according to instruction information and sends the control instruction to the pulse signal generation system; the pulse signal generation system generates a pulse signal according to the control instruction and sends the pulse signal to the biological stimulation electrodes; alternate electric pulse excitation is carried out on two key sites for inducing gait motion in spinal cord by the biological stimulation electrodes, the key sites for generating coordinated action of an inherent intermediate neural network for generating lower limb rhythm motion in spinal cord nerves are activated, and reconstruction of a lower limb gait motion function is effectively carried out in a mode of being closer to physiological conditions. The electronic system can be applied to animal experiments or rehabilitation training.

Description

technical field [0001] The invention relates to an intelligent control electronic system and a control method thereof in the field of rehabilitation engineering, in particular to a spinal cord electric excitation device for reconstructing the gait movement function of lower limbs. Background technique [0002] Spinal cord injury leads to motor dysfunction of the limbs below the injured segment, which will not only bring physical and mental harm to the patient, but also cause a huge economic burden to the family and the whole society. Therefore, reconstructing the motor function of paralyzed limbs has always been an important topic in neuroscience research. [0003] After the adult central system is injured, it is difficult for the axons of upper neurons to grow to the originally connected lower neurons to form new functional synaptic connections, which brings challenges to the reconstruction of motor function after spinal cord injury. Researchers in neurobiology have been t...
