Validity and Inter-rater Reliability fo the Vagus Nerve Neurodynamic Test Among Healthy Subjects

NCT04192877 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

No results posted yet for this study

Summary

Vagus nerve neurodynamic test (VN-NDT) will be validated detecting the changes in vagus nerve anatomical position due to the combination of movements of the test. Healthy subjects will be enrolled and screened for neurological problems. A checklist for autonomic dysfuntion symptoms will be administered and heart rate at rest will be measured. Inter-rater reliability will be assessed comparing positive and negative cases identified by two blinded assessors, one expert and one novice. It will also be monitored and compared the amount of motion induced by the expert and the novice assessors during the VN-NDT admimistration. If symptoms will be produced by the VN-NDT using a pain drawing tool it will be defined the qualitiy and the location of them. Accuracy of the VN-NDT will be tested in the autonomic dysfunction symptom detection.

DIAGNOSTIC_TEST

Vagus Nerve Neurodynamic test

The VN-NDT has been developed starting from the VN morphology selecting the physiological movements that induce the greater mechanical tension on the nerve. The subjects will be assessed supine on an examination table with assessors standing at the cranial short side of the table. Upper cervical flexion and contralateral lateral flexion had been selected for loading the intracranial portion. The ipsilateral neck rotation had been selected for loading the cervical tract. Keeping the subject's head in the final movements combination gentle movements of the upper abdomen caudally and cranially had been selected for loading the thoracic tract and used as discrimination maneuver. The test will be declared positive (indicating abnormal responses) if symptoms will be felt in anatomical regions other than the neck on the same side of the test and discrimination maneuvers changed the subject's symptoms indicating a neurogenic source, otherwise it will be declared negative.
