Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the SCI patients were sub-grouped on the basis of symptoms into symptomatic and asymptomatic groups and measured HRV during resting and tilt up tests to compare their cardiovascular autonomic functions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In study protocol and the subjects were asked to lie down quietly for 5 minutes, closing their eyes and avoiding talking, moving hand, legs and body, and coughing during the test. R-R interval and blood pressure were measured beat-to-beat using Finometer® PRO (Finapres Medical Systems, Amsterdam, Netherlands) for 6 minutes each in two positions, supine and 60-degree angle on the tilt table.
