  • Patent number: 12515057
    Abstract: The present disclosure is directed to providing digital health services. In some embodiments, systems and methods for conducting virtual or remote sessions between patients and clinicians are disclosed. During the sessions, media content (e.g., images, video content, audio content, etc.) may be captured as the patient performs one or more tasks. The media content may be presented to the clinician and used to evaluate a condition of the patient or a state of the condition, adjust treatment parameters, provide therapy, or other operations to treat the patient. The analysis of the media content may be aided by one or more machine learning/artificial intelligence models that analyze various aspects of the media content, augment the media content, or other functionality to aid in the treatment of the patient.

  • Publication number: 20250325818
    Abstract: Systems and methods which provide for and enable sensing responsive signals with respect to the application of paresthesia-free stimulation are described. Sensing signal initiators may be utilized comprising one or more non-therapeutic and/or non-tonic pulses in the form of pinging-pulses configured for invoking responsive signals suitable for measurement and/or analysis in association with the application of neural stimuli. A sensing signal initiator technique may provide an interleaved implementation to introduce one or more pinging-pulses between burst groups of a burst stimulation regimen. Additionally or alternatively, a sensing signal initiator technique may provide a postfixed implementation to introduce one or more pinging-pulses by modifying a therapeutic stimulation burst so that the last phase of the passive discharge is replaced with pinging-pulse providing an active discharge.

  • Patent number: 12420094
    Abstract: A noninvasive/minimally invasive neuromodulation system and method for providing therapy to a target neural tissue of a patient. In one arrangement, an example method comprises applying at least two input waveforms to respective pairs of electrodes affixed on the patient's skin or subcutaneously disposed relative to the target neural tissue, wherein the frequencies of the input waveforms are configured such that they combine, when simultaneously applied, to generate a beat waveform having a beat frequency due to interference. The beat waveform is causative of a transcutaneous/subcutaneous temporal interference (T/STI) electric field generated in the patient body, the T/STI electric field including an interference region at least partially overlapping the target neural tissue of the patient, wherein the beat frequency is of a value operative to impart a therapeutic effect to the target neural tissue.
