  • Publication number: 20240123230
    Abstract: Restless Leg Syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) can be treated using high frequency (HF) electrostimulation. This can include selecting or receiving a subject presenting with RLS or PLMD. At least one electrostimulation electrode can be located at a location associated with at least one of, or at least one branch of, a sural nerve, a peroneal nerve, or a femoral nerve. HF electrostimulation can be delivered to the subject, which can include delivering subsensory, subthreshold, AC electrostimulation at a frequency that exceeds 500 Hz and is less than 15,000 Hz to the location to help reduce or alleviate the one or more symptoms associated with RLS or PLMD. A charge-balanced controlled-current HF electrostimulation waveform can be used.

  • Publication number: 20220218993
    Abstract: Techniques to help improve efficiency or effectiveness of treating a disorder such as RLS or PLMD, such as by issuing neural electrostimulations to a particular patient, while varying one or more amplitude parameters (e.g., at least one of electrostimulation current amplitude, electrostimulation voltage amplitude, or electrostimulation pulsewidth duration). A corresponding patient-subjective or patient-objective response can be observed. A characteristic electrostimulation intensity relationship can be generated, for example, based on the determined respective at least one of RLS or PLMD response indication threshold amplitude parameters and the plurality of corresponding neural electrostimulation durations.

  • Publication number: 20220143393
    Abstract: Systems and methods for treating a patient having symptoms of restless legs syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) using high-frequency stimulation by applying a high-frequency pulsed electrostimulation therapy signal to a femoral nerve or a branch thereof. An electrostimulation device can include or use clonus detection circuitry can be used such as to monitor for a presence of clonic activity during treatment. Feedback from the clonus detection circuitry can be used to select or modify a therapy parameter of the electrostimulation device such as to help mitigate clonic muscle activity during therapy.

  • Publication number: 20220088372
    Abstract: Systems and methods for treating a patient having symptoms of restless legs syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) using high-frequency stimulation by applying a high-frequency pulsed electrostimulation therapy signal to a peroneal nerve or a branch thereof, where the therapy signal is above a motor threshold of a muscle innervated by the peroneal nerve or branch thereof. Surface EMG (sEMG) response to neurostimulation can be used to evaluate patient responsivity to neurostimulation, or to evaluate neurostimulation efficacy, such as to compare various neurostimulation parameter settings and to select between such settings to meet or balance between one or more goals. The sEMG response can be obtained with the muscle at rest, or during muscle activation.
