Variable amplitude signals for neurological therapy, and associated systems and methods
First Claim
1. A method for deploying a patient therapy system, comprising:
- implanting in a patient'"'"'s spinal cord region at least one signal delivery device having at least one signal delivery contact;
connecting an external signal generator to the at least one signal delivery device;
activating delivery of a first electrical therapy signal to the patient, including a process of repeatedly delivering the first electrical therapy signal to the at least one signal delivery contact at a first set of therapy signal amplitudes; and
if the patient responds favorably to receiving the delivered first electrical therapy signal,implanting an implantable signal generator in the patient andafter implanting the signal generator, delivering a second electrical therapy signal to the patient at multiple amplitudes of a second set of therapy signal amplitudes.

Abstract
Variable amplitude signals for neurological therapy, and associated systems and methods are disclosed. A representative method includes activating automatic delivery of an electrical therapy signal to a patient'"'"'s spinal cord region at a frequency in a frequency range between 1.5 kHz and 100 kHz, via at least one signal delivery contact carried by an implanted signal delivery device. The delivery can include repeatedly and automatically delivering the electrical therapy signal at each of multiple therapy signal amplitudes to the at least one signal delivery contact, without the therapy signal generating paresthesia in the patient. The foregoing process can be used as a screening tool to screen responders from non-responders in the context of a non-paresthesia-generating therapy, and/or can be used during long-term treatment, for example, for chronic pain.
