Tender point count (TPC) is central to fibromyalgia syndrome (FMS), and with total myalgic score (TMS) is often used to monitor the patient’s condition. This study aimed to determine the stability of TPC and TMS over time, and to examine how well these measures reflected patients’ perceptions of their condition. Twenty four patients with FMS completed the Fibromyalgia Impact Questionnaire (FIQ) and a visual analogue scale (VAS) measuring wellbeing, at entrance into the study, and 7 and 28 days later. There was no significant change in TPC (p = 0.074), FIQ score (p = 0.291) or VAS (p = 0.079) of wellbeing with time. However, mean TMS score did change over time (p = 0.021). There was no correlation between total FIQ score and the other measures (all p values > 0.05). The significant change in TMS over time may reflect the natural fluctuation in the clinical presentation of FMS.
