ABSTRACT

Background: Cervical radiculopathy (CR) is largely a clinical diagnosis and cortical stimulation has emerged as an effective and promising modality in the investigation of novel approaches for pain relief. Objective: The aim of this work is to investigate whether high and low frequencies of repetitive transcranial magnetic stimulation (rTMS) have a pain relieving effect in patients with radicular pain assessed by different pain scales and if these effects are prolonged or only short lasting. Subjects and Methods: This study was carried out on 20 patients, 10 received 20 hertz rTMS protocol and the others received 1hertz rTMS protocol. Pain scales: visual analogue scale(VAS), brief pain inventory (BPI): pain severity score(PSS) and pain interference score (PIS) used to assess the clinical efficacy of rTMS sessions on pain. Results: There was a highly statistically significant reduction of pain scores (VAS, PSS, PIS) after treatment compared to before treatment (p<0.01). In spite of that the pain scores increased 4 weeks after the last treatment session, these scores were still significantly less than those before treatment in both groups. Conclusion: rTMS can be used as a noninvasive therapeutic test for patients with drug-resistant chronic pain with more reduction of pain scales ratings in the high frequency group.
