Assessment of Remote Approaches for Identification of Autonomic Dysfunction Among Survivors of Leukemia and Lymphoma

Each participant will complete an in-person standardized clinical assessment for AD, called the Ewing battery. during the participants' Human Performance Lab during their SJLIFE functional exam. It is estimated it will take 60-90-minutes to complete the Ewing battery. The tests include monitoring heart rate variations during deep breathing and lying down to standing, as well as monitoring blood pressure variations when standing and maintaining hand grip. Participants will be asked to not consume aspirin, ibuprofen or acetaminophen 24-hours before the assessment. Additionally, participants will be asked to avoid alcohol or caffeine within 6-hours, and smoking 3-hours, before testing. After the in-person assessment, each participant will be given a wrist biosensor to remotely monitor heart rate variability for 7 days after they return home. Participants will also complete an AD symptom questionnaire, COMPASS31. The AD symptom questionnaire will be completed either before or after the in-person assessment. This questionnaire will take about 20-30 minutes to complete.
