Fatigue Severity Scale

The Fatigue Severity Scale (FSS) is a tool used to measure the severity and impact of fatigue on an individual's daily life. It consists of a series of statements about how fatigue affects various aspects of functioning, and respondents rate their agreement on a scale. This helps healthcare providers assess the level of fatigue experienced, particularly in conditions like multiple sclerosis, chronic fatigue syndrome, and other illnesses. By understanding a person's fatigue levels, appropriate treatments and interventions can be planned to improve quality of life.
