This study is a prospective, randomized study comparing ReActiv8 Therapy to Optimal Medical Management (OMM), where OMM means the patient is managed according to available guideline-directed treatments (e.g., medication, physical therapy, injections) individualized to meet the patient needs. All patients who satisfy the enrollment criteria are randomized (1:1) to receive either ReActiv8 (Treatment group) or OMM (Control group).
