Provided herein are methods for treating autism; and systems and devices for administering transcutaneous auricular vagal nerve stimulation (taVNS).

Methods of accelerating clot formation and increasing clot deposition in a hemophiliac subject. A vagal nerve stimulator (VNS) may be implanted in a hemophiliac subject. The hemophiliac subject may have developed antibodies to factor VIII and not been administered a clotting factor within the last 48 hours. The vagus nerve of the subject may be stimulated in a manner that increases platelet intracellular calcium and / or activates splenic acetylcholine-synthesizing T lymphocytes using the implanted VNS.

The disclosure provides systems and methods for automatically titrating an electrical pulse amplitude for a patient-implanted VNS stimulator. One or more external sensors (e.g., EEG, EKG, EMG, auditory sensors, inertial motion sensors, etc.) can be applied to the patient to generate data relevant to an acceptable amplitude of the electrical pulse for a given cathode in a multi-cathode cuff. In one embodiment, the device may include a controller on the implanted VNS stimulator that receives data, e.g., using a wireless connection, from the external sensors and titrates upward the amplitude until an acceptable amplitude is determine that provides efficacy with minimal, if any, side effects.

This invention relates to the field of computer-aided diagnostic technology, and specifically discloses a psychological trauma treatment system based on HRV monitoring and transcutaneous vagus nerve stimulation. The system eliminates the interference of time overlap on physiological indicators through HRV rhythm correction, eliminates the limitations of single indicator assessment through multi-dimensional data fusion, and achieves dynamic adaptation of intervention programs through subtyped taVNS treatment and closed-loop feedback, thereby reducing the bias in assessing the severity of psychological trauma and improving the accuracy of treatment.

The application discloses a kind of based on motor imagination and collaborative stimulation brain-computer interface rehabilitation training system and method.The system includes signal acquisition module, data processing module and collaborative stimulation module.Data processing module is based on affine invariant riemannian metric and Transform model according to the multi-channel electroencephalogram signal of acquisition, generates movement intention decoding result and trigger signal;Collaborative stimulation module responds to trigger signal, drives functional electrical stimulation and vagus nerve stimulation unit to execute synchronous stimulation, constitutes closed-loop rehabilitation training.The core lies in that decoding unit is reduced by dimension to electroencephalogram signal by based on affine invariant riemannian distance unsupervised clustering, then input Transform model classification, in combination with the double verification mechanism of trigger control unit, realize high-precision intention decoding and reliable trigger.The present application accurately synchronizes central nervous regulation and peripheral muscle feedback, effectively improves the neural remodeling efficiency and system generalization ability of motor function rehabilitation.
