Abstract:
The purpose of the study was to examine the association between the subjective sleep quality and pain threshold in fibromyalgia. Sixteen patients with fibromyalgia were included in the study. The pain threshold was determined using a manual algometer. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. The pain threshold was negatively correlated with the scores for subjective sleep quality, habitual sleep efficiency, and sleep disturbance and the PSQI global score. We conclude that there is a negative correlation between pain and sleep disturbance: increased pain sensitivity is associated with greater sleep disturbance.
