Theta Burst Stimulation vs Standard TMS
3 Minutes vs 37 Minutes

3 minutes vs 37 minutes. Same results. That’s not a typo. Theta burst stimulation (TBS) delivers TMS treatment in a fraction of the time. Standard rTMS takes 37 minutes per session. Intermittent TBS (iTBS) takes just 3-9 minutes — same number of total pulses, condensed into a rapid burst pattern.

What You’ll Learn

• How theta burst and standard rTMS differ technically
• The landmark THREE-D trial results
• Session experience comparison
• Cost differences
• Which to choose based on your situation

How They Differ

Standard rTMS:

• 10Hz repetitive pulses
• 3,000 pulses per session
• 37 minutes per session
• 36 sessions over 6-9 weeks
• The original FDA-cleared protocol (2008)

Intermittent Theta Burst (iTBS):

• Bursts of 3 pulses at 50Hz, repeated at 5Hz intervals
• 600 pulses per session (fewer but more potent bursts)
• 3-9 minutes per session
• 36 sessions over 6-9 weeks
• FDA-cleared (NeuroStar Express) based on the THREE-D trial

The THREE-D Trial

Published in The Lancet in 2018, the THREE-D trial randomized 414 patients to iTBS vs standard 10Hz rTMS. The results:

• iTBS was non-inferior to standard rTMS — equivalent efficacy
• Response rate: iTBS 49% vs standard 47% (no real difference)
• Remission rate: iTBS 32% vs standard 28% (no real difference)
• iTBS took 3 minutes vs 37 minutes
• No meaningful difference in side effects

Same outcomes. A fraction of the chair time.

Why Theta Burst Matters

• Time: 3-9 minutes vs 37 minutes — a game-changer if you’re fitting treatment into a workday
• Clinic throughput: Clinics can treat more people per day
• Sticking with it: Easier to commit to 3-minute appointments five days a week
• Cost potential: Shorter sessions could mean lower costs (though most clinics charge the same right now)

When Standard rTMS Might Be Better

• Some people report less scalp discomfort with the longer, more gradual protocol
• If iTBS didn’t work for you, trying standard rTMS gives you a different stimulation pattern
• Some clinics only have standard rTMS capability — not all devices support theta burst
• Certain research protocols still use standard parameters

Cost

Most clinics charge the same per session regardless of protocol:

• $200-$400 per session for either
• Insurance covers both equally
• If there’s a cost difference, it’s small

Choose iTBS (theta burst) if: You have a busy schedule, want the most convenient option, or your clinic offers it.

Choose standard rTMS if: You prefer gradual, steady stimulation, iTBS didn’t work for you, or your clinic only offers standard protocols.
