How Long Does an rTMS Treatment Last, and How Many Sessions Does It Include?
Conventional and accelerated protocols organize rTMS sessions in different ways.
The duration of a repetitive transcranial magnetic stimulation (rTMS) treatment can't be answered with a single number. Different protocols exist, and each organizes the number, frequency, and length of sessions according to its goal.
Conventional Protocols
In a conventional schedule, sessions are usually held several days a week over several weeks. Each visit includes one application, and the person returns to the center on the scheduled days.
This distribution allows the stimulation dose to build up progressively. The length of each application depends on the pattern used and the equipment.
Accelerated Protocols
Accelerated protocols concentrate several applications into a single day. Defined intervals are kept between them, because the time between sessions is also part of the design.
The SAINT protocol is the best-known example: it organizes treatment over five consecutive days and delivers several applications daily. This reduces the number of weeks involved, but turns each day into a more intensive experience.
Session, Application, and Full Course of Treatment
When comparing proposals, it helps to clarify the vocabulary. Sometimes "session" is used to describe each individual application; other times, it refers to a full day. Asking about the number of applications, the length of each one, and the total time avoids confusion.
It also helps to know the intervals, the number of visits, and how much time will be spent at the center.
Why Doesn't Everyone Receive the Same Schedule?
The protocol depends on the indication, clinical status, history, previous treatments, and available technology. The stimulated area, intensity, and frequency also vary.
Personalization isn't just a matter of changing one number. It involves selecting a coherent set of parameters and tracking the response over time.
When Are Results Assessed?
Assessment begins before the first session. Symptom scales and questions about day-to-day functioning help establish a baseline.
During treatment, changes and tolerability are monitored. At the end, results are compared and follow-up is decided. The response can continue to evolve after the last application.
Are There Maintenance Sessions?
Some people receive later sessions, while others continue with check-ups or other interventions. The need for maintenance, along with its frequency and duration, should be defined based on each person's individual progress.
Questions to Help You Plan
Before starting, it's useful to ask:
- What protocol will be used?
- How many days do I need to attend?
- How many applications will there be per day?
- How long does each visit last?
- How will the response be assessed?
- What follow-up is proposed?
Understanding the time structure makes it possible to plan around work, travel, support, and rest. It also helps in comparing alternatives with concrete information.
