SERENITY is a remote observational study designed to characterize between-subject heterogeneity in adults with chronic low back pain and adults with spinal cord injury-related neuropathic pain.\n\nThe study will enroll 200 adults with chronic low back pain and 200 adults with spinal cord injury-related neuropathic pain. Participants will complete baseline demographic, clinical, pain, emotional functioning, physical functioning, and quality-of-life assessments. Participants will also complete ecological momentary assessment surveys 4 times per day for at least 3 weeks. These surveys will assess pain intensity, pain interference with function, positive and negative affect, stress, sleep, body and mind awareness, agency or perceived control over pain and life, medication dosage, manual therapy frequency, and brief cognitive test performance.\n\nFitbit data will be collected passively during the study period to measure sleep, physical activity, heart rate, heart rate variability, daily readiness, and stress management. The study will use intensive longitudinal data from ecological momentary assessment surveys and Fitbit measures to develop Bayesian hierarchical models, pain-profile clusters, and personal causal models.\n\nThe primary objective is to identify SERENITY measures associated with or causally related to pain interference within each pain group. The study will also examine heterogeneity in pain profiles and explore person-specific causal relationships between pain interference and measures of pain severity, stress, cognition, body and mind awareness, affect, and agency.","Adults with chronic low back pain and adults with spinal cord injury-related neuropathic pain will be recruited nationwide for this remote observational study.
