Abstract
Extended pain relief via high frequency spinal cord modulation, and associated systems and methods. A method for treating a patient in accordance with a particular embodiment includes selecting a neural modulation site to include at least one of a dorsal root entry zone and dorsal horn of the patient's spinal cord, and selecting parameters of a neural modulation signal to reduce patient pain for a period of time after ceasing delivery of the signals, the period of time being at least one tenth of one second.
Claims20
A patient treatment method, comprising:
- selecting a neural modulation site to include a dorsal horn of a spinal cord of the patient;
- and
- desensitizing a wide dynamic range neuron at the dorsal horn by applying to the dorsal horn a non-paresthesia producing neural modulation signal having a signal frequency in a range of from about 1.5 kHz to about 100 kHz, to address patient pain, the pain being addressed for a period of time after at least reducing an intensity of the signal, the period of time being at least one tenth of one second.
A patient treatment method, comprising:
- selecting a neural modulation site to include a dorsal horn of a spinal cord of the patient;
- and
- desensitizing a wide dynamic range neuron at the dorsal horn by applying to the dorsal horn a non-paresthesia producing neural modulation signal having a frequency of from about 3 kHz to about 100 kHz to reduce patient pain.
