HRV-B for Symptom Management in Sickle Cell Patients

This study will test the hypothesis that Heart Rate Variability Biofeedback (HRV-B) restores autonomic balance and reduces pain and other symptoms among patients with sickle cell disease (SCD).The specific aims of this study are to: (1) conduct a randomized, wait list controlled, pilot intervention trial to determine whether HRV-B increases HRV coherence among SCD participants (minimum N of 30, up to 50 total); (2) determine whether HRV-B reduces pain, stress, fatigue, depression or insomnia among SCD participants; and (3) determine whether increases in HRV coherence are associated improvements in pain, stress, fatigue, depression, or sleep among study participants.
