概要

There are currently several points concerning rTMS for pain relief that have a huge impact in the practical application of rTMS in clinical practice, but which have not been approached by previous studies. Also, an even more important issue is the frequency of the sessions in each treatment protocol. The idea of performing stimulation in chronic pain patients on a consecutive daily basis for long-term treatments seem unrealistic and potentially costly. However, it has been reported in animals, healthy subjects and FM patients that the analgesic effects of rTMS can outlast the stimulation session for several minutes and even days. This has led to the proposal that pain treatment with rTMS could be performed in consecutive daily induction sessions, followed by spaced (weekly, fortnightly and even monthly) maintenance sessions. This approach is similar to what is performed routinely in patients with major depression treated by rTMS to the dorsolateral prefrontal cortex, and has successfully been tested in FM patients in a single- center study. Should this approach prove effective in larger prospective multicentric studies, rTMS could enter the armamentarium of non-invasive, non- pharmacological, low-adverse event therapeutic options to relieve fibromyalgia- related pain and associate symptoms. Hence, our aim is to conduct a multicentric international clinical trial on the influence of rTMS in the control of pain in a consecutive adaptive trial design where conventional rTMS (10Hz) and patterned rTMS (theta-burst) will be studied. Stimulations will be performed in a clinical practice-friendly approach, where daily maintenance sessions will be followed by weekly, and fortnightly stimulation sessions. There have been very scarce adaptive trials in the pain and non-invasive stimulation fields. This methodological approach allows for the use of lower number of patients in consecutive trials and, among other qualities, it allows for the imputation of data from the first trial into the second one, thus decreasing the duration of the studies and the number of participants.
