In various embodiments, non-invasive methods to induce motor control in a mammal subject to spinal cord or other neurological injuries are provided. In some embodiments the methods involve administering transcutaneous electrical spinal cord stimulation (tSCS) to the mammal at a frequency and intensity that induces locomotor activity.

Multi-site transcutaneous electrical stimulation of the spinal cord for facilitation of locomotion

A neuromodulation system, device, and method are disclosed. In an embodiment, a neuromodulation system includes a processor, a signal generator, a first electrode, and a second electrode. The processor in cooperation with the signal generator, the first electrode, and the second electrode are configured to deliver a transcutaneous stimulation to a mammal. The transcutaneous stimulation is configured by the processor for inducing voluntary movement in the mammal. The first electrode is positioned transcutaneously on a spinal cord and/or spinal cord dorsal roots of the mammal. Additionally, the second electrode is placed transcutaneously on or over at least one of the spinal cord and/or the spinal cord dorsal roots, a muscle, a nerve, or on or near a target end organ or bodily structure of the mammal. The second electrode is in communication with the first electrode through a hardwire or wireless connection.

Non invasive neuromodulation device for enabling recovery of motor, sensory, autonomic, sexual, vasomotor and cognitive function

Transcutaneous neuromodulation system and methods of using same

A neuromodulation system, device, and method are disclosed. In an embodiment, a neuromodulation method includes providing a neuromodulation system including a processor, a signal generator communicatively coupled to the processor, and at least one transcutaneous electrode communicatively coupled to the signal generator. The method also includes causing the at least one transcutaneous electrode to be applied a human patient having at least one dysfunctional spinal circuit. The method further includes facilitating transcutaneous electrical stimulation of the patient's spinal cord via the processor in cooperation with the signal generator causing activation of at least one spinal network ('SN') to enable or improve voluntary movements of the patient's arms, trunk, and legs, or autonomic control of at least one of sexual activity, vasomotor activity, speech, swallowing, chewing, cardiovascular function, respiratory activity, body temperature, metabolic processes, or cognitive function.

A wireless implant and associated system for motor function recovery after spinal cord injury, and more particularly a multi-channel wireless implant with small package size. The wireless implant can further be used in various medical applications, such as retinal prostheses, gastrointestinal implant, vagus nerve stimulation, and cortical neuromodulation. The system also includes a method and its implementation to acquire the impedance model of the electrode-tissue interface of the implant.

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

A neuromodulation system and a method of inducing voluntary movement in a mammal with a spinal injury are disclosed. In an example, a neuromodulation system includes a processor, a signal generator, and at least one electrode. The processor, in cooperation with the signal generator and the at least one electrode are configured to deliver a transcutaneous stimulation to a mammal. The transcutaneous stimulation includes during a first time period, a transcutaneous electrical spinal cord stimulation ('tESCS') applied to the mammal during physical conditioning of the mammal. The transcutaneous stimulation also includes during a second time period after the first time period, the tESCS applied to the mammal during reduced or no physical conditioning of the mammal. The tESCS applied during the first time period and the second time period is used to establish a functional baseline of the mammal.

Method of transcutaneous electrical spinal cord stimulation for facilitation of locomotion

In various embodiments a method of synergistically using a neuromodulation stimulator and a robotic exoskeleton for the restoration of voluntary movement and greater muscle activation in chronically paralyzed subjects is provided. The noninvasive neuromodulation system delivers signals to facilitate the restoration and/or enhancement of neurological function where at least one effect is strengthened stepping capacity that can be further substantiated when coupled with robotic exoskeleton assistance.

Concerted use of noninvasive neuromodulation device with exoskeleton to enable voluntary movement and greater muscle activation when stepping in a chronically paralyzed subject

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

In one example embodiment, a neuromodulation system for inducing locomotor activity in a mammal, in cooperation with a signal generator and an electrode, delivers a signal with an overlapping high frequency pulse to a mammal.

Neuromodulation systems are described comprising a signal generator and at least one electrode. The at least one electrode can be configured to deliver a stimulation to a mammal, wherein the stimulation includes a biphasic signal and an overlapping high frequency pulse thereby inducing voluntary movement in the individual. Methods of administering the stimulation are also described.

In certain embodiments an electrode array for epidural stimulation of the spinal cord is provided where the array comprises a plurality of electrodes disposed on a flexible polymer substrate; said electrodes being electrically connected to one or more lead wires and/or connection points on an electrical connector; where the electrodes of said array are bonded to said polymer so that the electrodes can carry an electrical stimulation signal having a voltage, frequency, and current sufficient to provide epidural stimulation of a spinal cord and/or brain in vivo or in a physiological saline solution, without separation of all or a part of an electrode from the polymer substrate.
