Systems and methods for optimized waveform neural block
The present disclosure provides systems and methods relating to neuromodulation. In particular, the present disclosure provides systems and methods for identifying optimized waveforms for blocking neural conduction. The systems and methods of neuromodulation disclosed herein facilitate the treatment of various diseases associated with pathological neural activity. The optimized waveforms for blocking neural conduction are identified through use of a global optimization algorithm based on predetermined performance criteria. A plurality of waveforms are generated and evaluated for neuronal conduction block using a computational model of extracellular neuronal stimulation, and at least on candidate waveform having an optimized shape capable of blocking neural conduction is identified.
Automated customization of output intensity from a fitness apparatus
An intensity of fitness apparatus output can be customized for a user during a workout session. A user profile of the user may be accessed to determine a starting intensity value at which output is to be provided by the user's fitness apparatus. Based on this starting intensity value and on command data associated with a workout session, an intensity profile for the user may be determined (e.g., created), which is usable for controlling an intensity of the output of the fitness apparatus during the workout session. While media content featuring an instructor conducting the workout session is output on an output device, the user's device may send commands to the fitness apparatus to control the intensity of the output of the fitness apparatus in accordance with the starting intensity value and, subsequently, the intensity profile of the user.

Feedback Control of Neuromodulation
An automated method of controlling neural stimulation. A neural stimulus is applied to a neural pathway in order to give rise to an evoked action potential on the neural pathway, and the stimulus is defined by at least one stimulus parameter. A neural compound action potential response evoked by the stimulus is measured. From the measured evoked response a feedback variable such as observed ECAP voltage (V) is derived. A feedback loop is completed by using the feedback variable to control the at least one stimulus parameter value for a future stimulus. The method adaptively compensates for changes in a gain of the feedback loop caused by electrode movement relative to the neural pathway. A compensating transfer function is applied to the feedback variable, the compensating transfer function being configured to compensate for both (i) a distance-dependent transfer function of stimulation, and (ii) a distance dependent transfer function of measurement which is distinct from (i).

System and method for transcranial current loop brain stimulation
A method and device is described, which provides electrical stimulation to the brain of a person, where the device comprises an external portion and at least one implantable portion. The external portion provides the energy source for stimulation to the implantable portions. The implantable portions provide at least two conductive paths through the skull and use the skull's high impedance to generate a current loop with the focus of stimulation lying in the current path.
Neural Stimulation for Reduced Artefact
A neural stimulus comprises at least three stimulus components, each comprising at least one of a temporal stimulus phase and a spatial stimulus pole. A first stimulus component delivers a first charge which is unequal to a third charge delivered by a third stimulus component, and the first charge and third charge are selected so as to give rise to reduced artefact at recording electrodes. In turn this may be exploited to independently control a correlation delay of a vector detector and an artefact vector to be non-parallel or orthogonal.

Systems and methods for enhancing function of spine stabilization muscles associated with a spine surgery intervention
A method for enhancing muscle function of skeletal muscles in connection with a planned spine surgery intervention in a patient's back is provided. The method includes implanting one or more electrodes in or adjacent to tissue associated with one or more skeletal muscles within a back of a patient, the one or more electrodes in electrical communication with a pulse generator programmed for enhancing muscle function of the one or more skeletal muscles. Electrical stimulation is delivered, according to the programming during a time period associated with the planned spine surgery intervention, from the pulse generator to the tissue associated with the one or more skeletal muscles via the one or more electrodes, thereby improving neuromuscular control system performance of the one or more spine stabilizing muscles in connection with the planned spine surgery intervention to reduce the patient's recovery time associated with the planned spine surgery intervention.
