System for planning and/or providing neurostimulation for a patient

The present invention relates to systems and methods for planning and/or providing neurostimulation for a patient. An example system includes a pathological spinal cord map storage module for storing at least one pathological spinal cord map describing activation of a spinal cord of a patient, a healthy spinal cord map storage module for storing at least one reference map describing physiological activation of the spinal cord of at least one healthy subject, an analysis module for generating a deviation map, the deviation map describing an activation difference between the pathological spinal cord map and the reference map, and a compensation module for calculating, based on the deviation map, a neurostimulation protocol for compensating the activation difference.

Methods and systems for tremor reduction

A tremor-reduction system is provided that delivers electric current to a body region of a subject that is associated with a tremor. A computing device stores received data associated with a tremulous movement of the body region and determines measurements associated with the stored data. If a magnitude of the most recent tremulous movement is the same as or greater than magnitudes associated with prior tremulous movements, characteristics of a subsequent electric current to be applied to the body region may be adjusted.

Biosignal acquisition method and algorithms for wearable devices

Apparatus, including a set of N electrodes (22), configured to be located in proximity to an epidermis (24) of a subject, and to acquire signals generated by electric sources within the subject. The apparatus also includes a set of M channels, configured to transfer the signals, where M is less than N, and a switch (40), configured to select, repetitively and randomly, M signals from the N electrodes and to direct the M signals to the M channels. The apparatus further includes a processor (28), configured to activate the switch, and to receive and analyze the M signals from the M channels so as to determine respective positions of the electric sources within the subject.

Continuous long-term monitoring of a subject

A method includes obtaining monitoring data recorded by first and second devices, the first and second devices being attached to the subject at different first and second sties, respectively. The monitoring data comprises signals associated with at least one physiological parameter of the subject. The method also includes extracting one or more features of the signals recorded by the first and second devices during a transitionary period when the first and second devices simultaneously monitor the at least one physiological parameter of the subject. The method further includes generating at least one correlation parameter by analyzing the extracted features of the signals recorded by the first and second devices for at least a portion of the transitionary period, the at least one correlation parameter when applied to signals recorded by the second device at least partially compensating for relative changes in signals recorded by the first and second devices.

Monitoring and management of physiologic parameters of a subject

A method includes receiving monitoring data from at least one sensing device coupled to a subject and analyzing the monitoring data to identify one or more physiologic parameters of the subject. The method also includes providing signaling to at least one stimulating device in response to the identified physiologic parameters, the signaling comprising instructions to apply a stimulus to the subject. The method further includes receiving additional monitoring data from the at least one sensing device, analyzing the additional monitoring data to identify one or more changes in the one or more physiologic parameters of the subject after application of the stimulus to the subject, and providing additional signaling to the at least one stimulating device, the additional signaling comprising instructions to modify the stimulus applied to the subject based on the identified changes in the one or more physiologic parameters.
