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.
