The greatest improvements were in Fibromyalgia Assessment Status (FAS), and the smallest in tender point score (TPS) and Short Form 36 Health Survey (SF-36) physical component scale summary score (PCS) and mental component scale summary score (MCS). FIQ = Fibromyalgia Impact Questionnaire; GH = perceived general health; SAPS = Self-Assessment Pain Scale.
