In this single-blind prospective study, patients with radicular pain at the C4, C5, or C6 level were randomly assigned to 1 of the 2 treatments: targeted CIESI or standard C7-T1 CIESI. Assessments were conducted before the initial injection and at follow-up sessions at 2 weeks and 1, 3, and 6 months, which included the following measures: Numerical Rating Scale (NRS) for pain, Oswestry Neck Disability Index (ONDI), Pain Disability Index (PDI), McGill Pain Questionnaire (MPQ), Patient Global Impression of Change (PGIC), daily morphine equivalents (DME), and Medication Quantification Scale (MQS) III scores. NRS scores at 1 month represented the primary study outcome, while the remaining measures were the secondary outcomes.
