Adult patients with Ehlers-Danlos syndrome who have chronic pain may be eligible for this 4 1/2 [Note: if the symbol is unreadable, it is four and one-half] to 5-month study. Patients not already enrolled in NHGRI's protocol 97-HG-0089 will undergo a history, physical examination, and brief interview before being accepted. Participants will attend 2-hour group sessions of mind-body therapy at NIH each week for at least 10 weeks. They will receive training in meditation, yoga breathing, guided imagery, and stress management in these sessions and will be asked to also practice the treatments at home each day. Patients may continue their regular medications and pain treatment with their private physicians during the course of the study.
