Methods of enabling locomotor control, postural control, voluntary control of body movements (e.g., in non-weight bearing conditions), and/or autonomic functions in a human subject having a spinal cord injury, a brain injury, or a neurological neuromotor disease are described.

High density epidural stimulation for facilitation of locomotion, posture, voluntary movement, and recovery of autonomic, sexual, vasomotor, and cognitive function after neurological injury

Methods comprising applying electrical stimulation to patients in conjunction with physical training are described.

Neuromodulation systems are described. An example neuromodulation system includes a controller wirelessly communicatively coupled to a host computer, a signal generator communicatively coupled to the controller, and a plurality of electrodes communicatively coupled to the signal generator. The controller, in conjunction with the signal generator and the at least one electrode are configured to deliver a stimulation to a mammal based on an instruction received from the host computer. The stimulation is configured to induce voluntary movement or restore function in the mammal.

Neuromodulation systems and methods of using same

Neurostimulator devices are described. An example neurostimulator device includes a stimulation assembly connectable to a plurality of electrodes, wherein the plurality of electrodes are configured to stimulate a spinal cord. The neurostimulator device also includes an interface and at least one processor configured to modify at least one complex stimulation pattern deliverable by the plurality of electrodes by integrating data from the interface and performing a machine learning algorithm on the at least one complex stimulation pattern.

Neurostimulator

Neurostimulator devices are described comprising: a stimulation assembly connectable to a plurality of electrodes, wherein the plurality of electrodes are configured to stimulate a spinal cord; one or more sensors; and at least one processor configured to modify at least one complex stimulation pattern deliverable by the plurality of electrodes by integrating data from the one or more sensors and performing a machine learning method implementing a Gaussian Process Optimization on the at least one complex stimulation pattern. Methods of use are also described.

Methods of enabling locomotor control, postural control, voluntary control of body movements (e.g., in non-weight bearing conditions), and/or autonomic functions in a human subject having spinal cord injury, brain injury, or neurological neuromotor disease are described.

An implantable electrode array assembly configured to apply electrical stimulation to the spinal cord. A substantially electrically nonconductive layer of the device has a first portion positionable alongside the spinal cord that includes a plurality of first openings. The layer has a second portion that includes a plurality of second openings. Electrodes and traces are positioned inside a peripheral portion of a body portion of the device and alongside the layer. At least one of the first openings is adjacent each of the electrodes to provide a pathway through which the electrode may provide electrical stimulation to the spinal cord. At least one of the second openings is adjacent each of the traces to provide a pathway through which the trace may receive electrical stimulation. At least one trace is connected to each electrode and configured to conduct electrical stimulation received by the trace(s) to the electrode.

Method of constructing an implantable microelectrode array

Described are devices including stimulation assemblies connectable to a plurality of electrodes. The plurality of electrodes can be configured to connect to a spinal cord at a location below a lesion of the spinal cord. The stimulation assembly can be configured to deliver stimulation to selected ones of the plurality of electrodes when the stimulation assembly is connected to the plurality of electrodes when located below the lesion of the spinal cord. Methods of using the devices are also described.

Spinal stimulator systems for restoration of function

Methods of enabling locomotor control, postural control, voluntary control of body movements (e.g., in non-weight bearing conditions), and/or autonomic functions in a human subject having spinal cord injury, brain injury, or neurological neuromotor disease. In certain embodiments, the methods involve stimulating the spinal cord of the subject using an epidurally placed electrode array, subjecting the subject to physical training thereby generating proprioceptive and/or supraspinal signals, and optionally administering pharmacological agents to the subject. The combination of stimulation, physical training, and optional pharmacological agents modulate in real time electrophysiological properties of spinal circuits in the subject so they are activated by supraspinal information and/or proprioceptive information derived from the region of the subject where locomotor activity is to be facilitated.
