CPNSS/DB SS-DA
Stress/anxiety measurement and evaluation system
The diagnosis on the basis of this measurement is based on the sympathetic/parasympathetic responses of the gastrointestinal (GI) region to stress. These responses can be detected based on the Myoelectric (EGIG) wave activity of the organs in the region (e.g., stomach, small intestine). Additional physiological parameters are measured simultaneously to verify the response:
- Myoelectric waves (EGIG)
- ECG (I lead)
- Body temperature (THB)
- Galvanic skin response (GSR)
- Respiratory rate – optional (RR)
- Wave-imaging sensors can be attached non-invasively on the preferred body surface for the purpose of the measurement.
- Clinical validation by applying the protocol of „TRIER” Social Stress test”.
- The examination is based on the continuous monitoring and storing of primary waves imaged from the body surface of the patient.
- Display in 8 channels: 2x 4 channel distribution, with a 12-step time-based setting (2 sec. – 5:33:20) per 4 channels.
- Per channel: Amplification, Filter settings, Value display.
- Automatic saving of primary curves linked to a patient ID.
- Two-step automatic evaluation (EGIG →FFT/PSDmax., GSR, THB. The statistics specifying abnormal divergences).
- Export: CSV (Excel format).
Clinical application
- The recording shows the wave responses to the resting phase of the “TRIER 1 test” on 2 x 4 channels.
- On the rights, the physiological values represent a resting state.
- The resting state of the EGIG waves on the left is confirmed by the physiological waves and values on the right.
- The “TRIER 2 test” includes a two-sided response to the stress induction phase.
- The wave and value responses of the stress phase verify the effect by the fact that the HR and THB increase, the GSR decreases, and the EGIG waves increase in every gastrointestinal organ.
Evaluation:
The system performs the evaluation simultaneously and automatically for all parameters.
Evaluation is done by parameter dimensioning (e.g. EGIG/PS, CPM).
- Evaluated data will be placed in an Excel spreadsheet, separated by parameters/dimensions.
- Based on the spreadsheets, coordinates can be edited and displayed in 2D and 3D.
- The proof of the effect clarifies the statistical evaluation.
- Statistical result validates the use of test score values.
