A probe system includes a finger-mountable housing having a distal end and a proximal receptacle end. The proximal receptacle end defines an opening to receive a finger. The probe system also includes a probe assembly disposed on or within the finger-mountable housing and having at least a first sensor. The first sensor is positioned to measure a physical characteristic of a first tissue when the finger-mountable housing and probe assembly are inserted in a rectum of the patient.

The present invention discloses a depression assessment system based on physiological information, comprising an information acquisition module, a signal processing module, a parameters calculation module, a feature selection module, a machine learning module and an output result module. The present invention further discloses a depression assessment method based on various physiological information, comprising the following steps: 1, processing electrocardiogram (ECG) signal and one or more of photoplethysmography (PPG) signal, electroencephalogram (EEG) signal, galvanic skin response (GSR)signal, electrogastrography (EGG) signal, electromyogram (EMG) signal, electrooculogram (EOG) signal, polysomnogram (PSG) signal and temperature signal, and calculating signal parameters; 2, normalizing the obtained signal parameters, and performing the feature selection on parameters set formed by the normalized signal parameters to obtain feature parameters set; and 3, performing machine learning by utilizing the obtained feature parameters set, and establishing a depression assessment mathematic model to assess the depression level by utilizing a relationship between the feature parameters set and the depression level. The present invention has the advantage that the subjectivity of the assessment by utilizing the depression rating scale can be avoided.

Embodiments of a method for removal and replacement of artifacts in electrophysiological data from muscular activity in the a gastrointestinal tract of a patient are disclosed. The approach includes setting an artifact identification threshold based on the parameters of the data, assessing the full extent of the artifact in time, and replacing the values with ones that are neutral in the time series and minimizing the effect on a power spectrum of the data. More particularly, the method includes steps of identifying artifacts within the raw time series data, eliminating the identified artifacts, and replacing the artifacts with any of interpolated points or constant value points to create a clean time series data set representing valid gastrointestinal tract EMG signals.

A method of detecting neural activity in a nerve is disclosed. A first electrical signal is received from a first pair of electrodes. A second electrical signal is received from a second pair of electrodes, the second pair of electrodes being spaced from the first pair of electrodes along the nerve. A correlation analysis is applied between the first and second electrical signals, including for at least one non-zero lag time, to obtain correlation data. From the correlation data, at least one neural signal is detected, indicative of neural activity in the nerve. The neural signal corresponds to increased correlation between the first and second signals at the at least one non-zero lag time.

An imaging probe adapter for measuring the properties of a lumen like the vaginal canal, the rectum, or anal sphincter. The device has an adapter body with a proximal end and a distal end. The distal end of the adapter body may be formed into an insertion tip capable of easy insertion into the appropriate lumenal structure. An inflatable pressure chamber covers the distal end of the adapter body. A baseplate formed on the proximal end of the adapter body incorporates fluid channels for inflating the pressure chamber and a probe channel that receives an ultrasound probe or other suitable imaging probe. The device is used to measure and model lumenal biomechanical properties such as stiffness, compliance, elastic versus viscous contributions to overall stiffness, and total displacement.

A method of predicting successful treatment of disorders of bodily tissue includes obtaining, with a device, energy signal data from the bodily tissue of a patient. The obtained energy signal data is analyzed in a controller to determine an activity score value associated with the bodily tissue. The activity score value is compared, in the controller, to a threshold value, with the threshold value being based on energy signal data from the same bodily tissue of normal, disease free patients. Based on the comparison, a probability of success of a particular therapy in treating the bodily tissue is determined. A system for performing the method is also disclosed.
