Pain in patients with myotonic dystrophy type 2: A postal survey in finland




Widespread 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.


A 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.


The 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.


Pain of moderate severity and unpleasant muscular symptoms are common in DM2. DM2 should be taken into consideration in the differential diagnosis of musculoskeletal pain. Muscle Nerve 45: 70–74, 2012
