Motor function in spinal cord injury patients via electrical stimulation, and associated systems and methods

Abstract:

Improving motor function in spinal cord injury patients (among others) via electrical stimulation, and associated systems and methods are disclosed. A representative method includes, in a patient having a spinal cord injury, improving the patient's gait response by delivering an electrical signal that includes repeating pulse packets delivered at a first frequency of from 2 Hz to 200 Hz. The electrical signal is delivered from an epidural location at the patient's spinal cord, and the individual pulse packets include a first period during which pulses are delivered at a first frequency of from 1 kHz to 5 kHz and a first pulse width of from 80 microseconds to 400 microseconds and a first amplitude from 0.1 mA to 20 mA, followed by a second period during which pulses are (a) not delivered, or (b) delivered at a second frequency higher than the first frequency, and/or a second pulse width shorter than the first pulse width, and/or a second amplitude less than the first amplitude.
