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

摘要

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.
