Chronic Pain
Conditions
Brief summary
This study investigated the effects of navigated repetitive Transcranial Magnetic Stimulation on nociception and quality of life in patients suffering from chronic pain conditions. Two cortical targets (dorsolateral prefrontal cortex/DLPFC and M1 area) were stimulated and compared to Sham stimulation.
Detailed description
From 34 patients, 24 completed the study. The M1-area was stimulated with 10 Hz rTMS while the DLPFC received a 5Hz stimulation. In total, 13 session were administered over a period of 36 weeks with most frequent stimulation in the first 4 weeks of the trial. Results were compared to Sham-TMS over the M1 area at the same schedule than the actual therapy. Outcome parameters included the German Pain Questionnaire (GPQ), the Depression, Anxiety and Stress Scale (DASS) and quality of life (QoL) with the SF-12 questionnaire.
Interventions
High frequency nrTMS over 13 sessions (1800-2000 pulses per session) over DLPFC and M1 cortical areas.

Study design
Masking description
Sham stimulation was provided by turning the TMS coil to the non-stimulating side.
Intervention model description
The study was conducted in a single-blinded, randomized, placebo-controlled design
