Quick answer
Standard rTMS spreads treatment across daily weekday sessions for six to nine weeks.
Accelerated protocols compress multiple sessions into a single day, finishing a full course in about a week.
The right course of TMS depends on your schedule, how quickly you need results, and what your evaluation shows about your history. Whichever schedule you choose, treatment at Compassion Neurohealth is guided by our Precision TMS process; EEG brain mapping, our proprietary HALO™ analysis platform, and neuronavigation; rather than the traditional “5-cm rule” most clinics rely on to locate the treatment site.
Introduction
TMS isn’t a single fixed protocol. It comes in a few different shapes, and the differences between them are significant enough to change how treatment fits into your life.
Here’s how standard rTMS, theta burst, and accelerated protocols actually compare, how to think about which one suits your situation, and how our Precision TMS targeting process applies no matter which schedule you choose.
Key takeaways
- Standard rTMS (repetitive TMS) runs daily on weekdays for six to nine weeks, with decades of research behind it.
- Intermittent theta burst (iTBS) delivers a similar dose in a few minutes instead of half an hour.
- Accelerated protocols pack multiple sessions into a single day, compressing a full course into about a week.
- Accelerated protocols are more often self-pay, since insurance coverage hasn’t caught up to the newer schedule.
- The safety screening process is identical across all three schedules. What’s different at Compassion Neurohealth is targeting: every course is guided by EEG mapping, HALO™ analysis, and neuronavigation, not the standard 5-cm rule.
Standard rTMS
Standard repetitive TMS is the original, most studied version of this treatment, and it remains the default most patients start with.
Session length, weekly schedule, total course length
A typical course runs 36 sessions over six to nine weeks, five days a week for the first six weeks with a taper afterward. Each session takes 20 to 40 minutes depending on the exact protocol used. At Compassion Neurohealth, a standard course still begins with our own EEG brain mapping and HALO™ analysis, so the treatment location is identified with millimeter-level precision rather than estimated using the 5-cm rule.
Who it suits
Standard rTMS suits patients who can commit to a daily weekday routine over several weeks and who prefer the protocol with the longest research history behind it.
Intermittent theta burst (iTBS)
Theta burst is a different pulse pattern delivered within a standard-length course, not a separate multi-week schedule.
What the burst pattern is and why it takes minutes rather than half an hour
iTBS delivers pulses in short, rapid bursts rather than the steady rhythm used in standard rTMS. That pattern compresses a full dose into roughly 3 minutes per session instead of 20 to 40. As with standard rTMS, the coil is guided to your personal HALO™-identified target rather than a generic estimated site.
What the non-inferiority evidence shows
In 2018, a multisite Canadian trial published in The Lancet (the THREE-D trial) compared iTBS directly against standard 10Hz rTMS for depression. Researchers found iTBS was non-inferior, meaning it performed comparably despite the shorter session length.
Accelerated protocols
Accelerated TMS keeps the same number of sessions as a weeks-long course, but folds it into a matter of days by delivering several sessions in a single day.
Multiple sessions per day and the spacing between them
Accelerated protocols commonly deliver anywhere from a few to as many as ten sessions in a single day, spaced roughly an hour apart to allow the brain time to recover between pulses. The same HALO™-guided targeting used in our standard and theta burst courses carries over here too, so compressing the schedule doesn’t mean compromising on where the pulses land.
Compressed course length
Instead of six to nine weeks, an accelerated course can finish in about five days, sometimes less depending on the specific protocol.
What the evidence currently supports and where it is still emerging
Early published trials on accelerated protocols, including Stanford-developed approaches, have reported strong short-term response in research settings. The evidence base is newer than standard rTMS, and researchers are still building out data on durability and real-world outcomes outside specialized trial conditions.
Side-by-side comparison
Here’s how the three stack up on time, schedule, and targeting.
Standard rTMS
- Session length: 20–40 minutes
- Sessions per day: 1
- Total course length: 6–9 weeks
- Total time commitment: highest overall, spread across many weeks
- Targeting: HALO™-guided Precision TMS
Intermittent theta burst (iTBS)
- Session length: about 3 minutes
- Sessions per day: 1
- Total course length: similar to standard rTMS, 6–9 weeks
- Total time commitment: less time per visit, same number of weeks
- Targeting: HALO™-guided Precision TMS
Accelerated protocols
- Session length: varies by protocol, often shorter individual sessions
- Sessions per day: multiple, commonly up to 10
- Total course length: about 5 days
- Total time commitment: concentrated into one week instead of spread across two months
- Targeting: HALO™-guided Precision TMS
Who each protocol suits
Each schedule fits different personal needs, and none of them is the objectively better choice.
Patients who cannot commit to six+ weeks of weekday appointments
Work schedules, caregiving responsibilities, and inconsistent availability make a nine-week daily commitment hard for some patients. An accelerated protocol condenses that same course into about a week.
Out-of-town patients
Patients traveling from outside the area sometimes prefer accelerated TMS specifically because it turns a two-month commitment into a single trip.
Patients where speed of response matters clinically
For patients in significant distress, finishing a full course sooner can fundamentally enable wellbeing.
Cost and coverage differences
Coverage looks different across these protocols, and that difference is mainly about how established each one is with insurers.
Why accelerated protocols are more often self-pay
Standard rTMS and iTBS are both FDA-cleared and widely recognized by insurance plans. Accelerated protocols are newer, and many insurance plans haven’t built coverage criteria for them yet, so they’re more often billed as self-pay. Our Precision TMS process; the EEG mapping, HALO™ analysis, and neuronavigation; is part of how we deliver every protocol at Compassion Neurohealth and doesn’t change how a given schedule is classified for coverage purposes.
What does not change between protocols?
Whichever schedule you choose, the underlying process behind it stays the same.
Motor threshold determination, targeting, safety screening
Most clinics locate the treatment site using the “5-cm rule,” estimating the target by measuring roughly five centimeters forward from the motor cortex.
At Compassion Neurohealth, every course instead begins with EEG brain mapping and our proprietary HALO™ analysis platform, which evaluates brain network patterns to identify which regions are underperforming or overperforming.
Neuronavigation then guides the TMS coil to that exact location with millimeter-level accuracy. Halfway through treatment, we re-measure brain activity to confirm the therapy is working and adjust targeting if needed, and a final measurement after treatment shows how brain activity has changed.
The safety screening for implants, seizure history, and medications is identical across all three schedules. Only the pulse pattern and schedule differ between standard rTMS, theta burst, and accelerated protocols; the measurement, targeting, and safety process is the same Precision TMS approach across all three.
Find the Protocol That Fits Your Life
The right protocol depends on your schedule, your history, and what your evaluation shows, not a general preference for “faster” or “more established.” Whichever schedule you land on, it’s delivered using the same Precision TMS process.
Frequently asked questions
Q: Is Accelerated TMS as Effective as the Standard Course?
A: Early research on accelerated protocols has reported strong short-term response, though the evidence base is newer and smaller than the decades of research behind standard rTMS.
Q: Does Insurance Cover Accelerated TMS?
A: Standard rTMS and iTBS are widely covered because they’re established and FDA-cleared. Accelerated protocols are newer, and many insurance plans haven’t built coverage criteria for them yet, so they’re more commonly self-pay.
Q: How Many Sessions Per Day Are Involved?
A: Accelerated protocols commonly deliver anywhere from a few sessions to as many as ten in a single day, spaced roughly an hour apart. The exact number depends on which specific protocol your provider recommends.
Q: Who Is Not a Good Candidate for an Accelerated Protocol?
A: Anyone with the same safety exclusions that apply to standard TMS, like certain implants or seizure history, is excluded from accelerated protocols too. Some patients also prefer the pacing of a longer course, which is a personal fit question as much as a clinical one.
Q: Is Theta Burst the Same Thing as Accelerated TMS?
A: Theta burst refers to the pulse pattern within a single session, shortening each visit to a few minutes. Accelerated TMS refers to the schedule, compressing multiple sessions into a single day. The two are often combined but aren’t the same thing.
Q: Can I Travel In for an Accelerated Course?
A: Yes, that’s part of why some out-of-town patients choose this protocol. Since a full course can finish in about five days, it turns treatment into a single trip instead of a multi-week commitment.
