Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The overall objective of BOLD is to establish a large, community-based registry (at least 5000 subjects) of patients aged 65 years and older presenting with new episodes of healthcare visits for back pain. BOLD's primary aim is to create an infrastructure that allows for the conduct of prospective, controlled studies comparing the effectiveness of diagnostic and treatment strategies for back pain in older adults.
