Embodiment 1

[0018] see figure 1 , the present invention is used for the three-dimensional grasping motion training device of clinical EEG signal analysis and comprises: loading panel 1, LED indicator light driver 2, infrared sensor processing circuit 3, microcontroller 4, EEG signal acquisition instrument 5, PC 6. The loading panel 1 is a square light wood board, which is placed in front of clinical patients at an angle of 45 degrees. The loading panel 1 has five square areas with magnetism, one is located in the center, and the other four are evenly distributed on the four sides. Each corner has a round hole in the center of each square area, and an infrared sensor (not shown in the figure) that can emit infrared rays through the round hole is installed at the bottom of the round hole, and a small LED indicator light is installed above each square; the infrared The sensor processing circuit 3 is connected to five sensors on the loading panel 1, and is provided with a sensor power supply ...

Embodiment 2

[0021] When in use, the loading panel 1 is placed in front of the clinical patient at an angle of 45 degrees, according to figure 1 In the square area shown, 5 infrared sensors are installed at the bottom of the round hole and connected to the infrared sensor processing circuit 3. LED indicators are installed above each square area and connected to the LED indicator driver 2, microcontroller 3. Connect to the LED driver 2 and the infrared sensor processing circuit 3 through the IO port, and connect to the PC 6 through the serial port to USB circuit. At the same time, the input end of the EEG signal acquisition instrument 5 is connected to the patient's brain cortex through the array electrode, and the output signal end is through the optical fiber. Connect PC6. During the experimental training, the clinical patient holds an object that can be adsorbed on the square area of ​​the loading panel. The surface size of the object is the same as the square area, and it is made of spe...

Abstract

The invention provides a three-dimensional stretching and grasping exercise training device, which includes a loading panel, an LED indicator light drive, an infrared sensor processing circuit, a microcontroller, an electroencephalogram signal acquisition instrument, and a PC. The device of the present invention realizes the automatic real-time capture of time stamps of stretching and grasping movements, and the collection of three-dimensional stretching and grasping motion data. Combined with the EEG signal acquisition instrument, the synchronization of brain nerve signals and motion data can be conveniently performed, and the EEG of three-dimensional stretching and grasping motions can be completed. Signal decoding. Compared with the existing exercise training device, the device of the present invention is reasonable in design, simple in structure, and convenient to use, which is beneficial for clinical patients to master and apply. It is especially suitable for patients with upper limb paralysis to do three-dimensional stretching and grasping exercise rehabilitation training through the brain-computer interface platform, and is also suitable for brain-computer interface Research and development of rehabilitation medical equipment in the field.

Description

technical field [0001] The invention belongs to a medical device, and relates to a three-dimensional stretching and grasping exercise device and method for clinical research on a brain-computer interface oriented to motor function, in particular to a three-dimensional stretching and grasping exercise training device and method for analyzing EEG signals . Background technique [0002] In the field of brain-computer interface research for motor functions, it is usually necessary to implant array electrodes in the brains of humans or animals to collect EEG signals from the relevant motor cortex, and decode these EEG signals to restore limb motor functions. At present, many experiments have realized the recording of EEG signals from the motor cortex of monkeys and rats, and achieved motor control by manipulating the brain-computer interface. However, due to the low spatio-temporal resolution of the collected EEG nerve signals, it is difficult to correspond the EEG nerve signals...
