What is the difference between FS (Fatigue Scale) and FSS (Fatigue Severity Scale)?
The FS (Fatigue Scale) and FSS (Fatigue Severity Scale) are different scales that measure fatigue. They both tap into differing aspects of fatigue to help us better define this state. Here is the Fatigue Scale and here is the Fatigue Severity Scale (both in MSWord). For FS, subjects pick the statement (ranked from 1 to 7) that most closely represents how they feel. For FSS, subjects respond on a scale from 1 to 7 to 9 questions and their average response is recorded (see this for more on FSS scores). • April 25, 2006: Are other overnight measurements like TST, SE, REM, etc. used to diagnose OSA or is the diagnosis just based on RDI? RDI is used to make the diagnosis. Those measurements (TST, SE, REM) tell us about the sleep quality, and we would expect to see poor SE (sleep efficiency – time from sleep onset to final awakening actually spent asleep) in sleep apnea patients but would expect that to improve after treatment. The same would go for TST (total sleep time). With regards to RE
