IntroductionWidespread musculoskeletal pain is a well-known symptom of myotonic dystrophy type 2 (DM2), but so far it has been addressed in only a few studies.MethodsA postal survey for all traceable DM2 patients (n = 132) was conducted. A specific questionnaire, and severity and interference subscales of the Brief Pain Inventory, quality of life (RAND-36), and modified Beck Depression Inventory were completed.ResultsThe response rate was 70%. The mean age of respondents was 53 years, 59% of whom were women. Current pain was reported by 54%. Lifetime prevalence of pain was 76%. The mean intensity of pain at its highest in the last week was 5.9, and 2.3 at its lowest (on a numerical rating scale of 0-10). Quality of life was lower in DM2 patients who reported pain. In 18%, the depression score was noticeably different.ConclusionsPain of moderate severity and unpleasant muscular symptoms are common in DM2. DM2 should be taken into consideration in the differential diagnosis of musculoskeletal pain.Copyright © 2011 Wiley Periodicals, Inc.
