Devices and methods for assessing motor point electromyogram as a biomarker
Described herein are methods of detecting the presence or progression of neuromuscular disorders (including ALS) based at least in part on diaphragm EMG signals taken at different points in time from the same implanted electrode(s). Signals may be used to diagnose or to monitor progression of a disorder or to track a treatment. Thus, diaphragm EMG signal may be used as a marker (e.g., a “biomarker”) for the detection or progression of a neurological disorder such as ALS. The characteristics or parameters of diaphragm EMG signals may be used to create an activity index, which may be output or compared and further analyzed. These signals may also be analyzed to show a difference between the left and right sides of the diaphragm.
Method and apparatus for monitoring an organ of a patient
An implanted device for an organ of a patient including a housing. The device includes a detector having electrodes that have a varying distance over time between them which produces a detector signal based on electrical signals derived from the organ. The device includes a signal processor disposed in the housing in communication with the detector which determines admittance from the detector signal based on the varying distance over time between the electrodes. The device includes a drive circuit disposed in the housing to cause the electrodes to generate emitted electrical signals. A method for monitoring a patient's organ.
Correlating brain signal to intentional and unintentional changes in brain state
Methods of analysis to extract and assess brain data collected from subject animals, including humans, to detect intentional and unintentional brain activity and other unexpected signals are disclosed. These signals are correlated to higher cognitive brain functions or unintended, potentially adverse events, such as a stroke or seizure, and to translation of those signals into defined trigger events or tasks.
Ultra-low power, miniaturized electronic systems for monitoring physical parameters with wireless communication capabilities and applications of same
An electronic system for monitoring a physical parameter includes an ADM comprising an accumulation mode sensor for measuring the physical parameter by generating electrical energy associated with the physical parameter in response to a surrounding condition, and an energy storing device coupled to the accumulation mode sensor for accumulatively storing the generated electrical energy; a power source; and an SoC coupling with the ADM and the power source, configured such that the stored electrical energy is monitored, and when the stored electrical energy is equal to or greater than a pre-defined threshold, a wake-up event is generated to trigger the SoC to operates in a run mode in which the physical parameter is wirelessly transmitted to a receiver and the stored electrical energy in the energy storing device is discharged, and then the SoC returns to a sleep mode in which a minimal power is consumed.

Systems and methods for use in treating sensory impairment
Methods and systems for use in treating one or more patient's sensory impairment, e.g., associated with peripheral neuropathy. An exemplary system may be configured to generate treatment information for treating sensory impairment in at least one body portion using photonic energy from a therapeutic laser based on data indicative of damage.
TECHNOLOGIES FOR BIOSIGNAL FEEDBACK FILTERING
Technologies for filtering biosignals include one or more biosignal sensors coupled to a user to receive biosignals and a computing device to receive biosignals from the biosignal sensors. The biosignal sensors filter the received biosignals to identify abnormal biosignals using a plurality of domain filters including a time domain filter and a frequency domain filter. The biosignals identified as abnormal by each of the domain filters are transmitted to the computing device, while the remaining biosignals are discarded.
