Chronic pain related to quality of sleep

OBJECTIVE: To determine the relation between the degrees of chronic pain and drowsiness levels. METHODS: The study was conducted with 115 patients, who answered the questionnaire as diagnostic criteria in the survey. After evaluation based on the protocol of chronic pain registry RDC/TMD- Axis II, the Epworth Sleepiness Scale was applied to assess drowsiness levels. RESULTS: Among the participating patients, there were more females (80%), and the type of pain more prevalent was chronic (70.4%). Concerning the grades of chronic pain, grade II predominated (38.3%), corresponding to high pain intensity and low disability. The ratio observed for levels of sleepiness was more prevalent for sleep debt average (38.3%). CONCLUSION: The grades of chronic pain and the levels of sleepiness did not correlate with each other or with the gender of patients.
