Correlation between the number of tender points in fibromyalgia, the intensity of symptoms and its impact on quality of life

OBJECTIVE: to study the correlation between the number of tender points and the intensity of the perception of key aspects of the fibromyalgia syndrome (pain, fatigue, anxiety, depression, and its impact in functional capacity). MATERIAL AND METHODS: forty-one records of patients who meet the Criteria for Classification of Fibromyalgia of the American College of Rheumatology were reviewed, focusing on the following variables: perception of the intensity of pain, fatigue, quality of sleep, depression, anxiety and the tender point count. The assessment of functional capacity was done by the Health Assessment Questionnaire (HAQ). RESULTS: There was a positive correlation between tender point count and pain intensity (p = 0.004), as well as HAQ scores (p = 0.0011). There was no correlation between tender point count and fatigue (p = 0.358), anxiety (p = 0.58), depression (p = 0.50) or physical capacity (p = 0.538). The correlation between the tender points count and pain intensity is stronger than with HAQ. CONCLUSION: there is a positive correlation between the tender point count, intensity of pain and functional capacity. The correlation between the tender point count and intensity of pain is more important than with functional capacity measured by the HAQ. There was no correlation with the other variables studied.
