| Description | Aim: Patients with myotonic dystrophy (MD) may suffer from variable types of pain and some descriptors suggest the involvement of a possible neuropathic pain component in MD patients. The aim of the study was to evaluate the occurrence of neuropathic pain descriptors and sensory abnormalities in patients with myotonic dystrophy type 2 (MD2) and to disclose the presence of some relevant psychological factors in chronic pain conditions. Patients and methods: A group of 23 patients with MD2 suffering from chronic pain and a group of 24 age- and gender-matched healthy controls were examined using the PainDETECT questionnaire and the Neuropathic Pain Symptom Inventory questionnaire (NPSI), a comprehensive protocol of quantitative sensory testing (QST) and a battery of self-reported psychological tests. Results: Based on the PainDETECT questionnaire, the presence of a neuropathic component of pain was evaluated as possible or probable in more than half of the patients. According to the NPSI questionnaire, the most frequently described spontaneous pain in patients with MD2 was squeezing. Very common are brief pain attacks of stabbing pain, and two thirds of patients also described abnormal sensations (pins and needles and/or tingling) in the painful area. QST in lower legs showed significantly more frequent hypoesthesia for cold and hyperalgesia for mechanical pain stimuli and also higher incidence of paradoxical heat sensation. Patients with MD2 also showed significantly more frequent depression and pain catastrophizing. Conclusion: The pain descriptors evaluated by PainDETECT and NPSI questionnaires, and sensory profile assessed by the QST protocol performed in this pilot study support the hypothesis that pain in MD2 patients probably has a neuropathic component. |
