Trial Outcomes & Findings for American Ginseng Treatment for Multiple Sclerosis Related Fatigue (NCT NCT00754832)

NCT ID: NCT00754832

Last Updated: 2012-01-24

Results Overview

The Fatigue Severity Scale (FSS)is a self-administered instrument that includes 9 items rated on a 7-point scale, measuring fatigue severity. The subject is asked to score each statement, based on how the statement applied to them over the preceding week. The fatigue severity score is the average of the scores on the 9 questions; scores range from 1-7, with lower scores indicating less fatigue.
