This pilot randomized trial compared the effectiveness of intermittent theta-burst stimulation (iTBS) and H-Coil transcranial magnetic stimulation (rTMS) in 28 adults with treatment-resistant depression (TRD). After six weeks, there were no significant differences in Hamilton Depression Rating Scale scores between the two groups (mean difference -0.40, 95% CI -5.23 to 4.43; p=.865).
Key findings
- Adjusted week-6 HRSD-17 scores did not differ between iTBS and rTMS groups (mean difference -0.40).
- Response rates were 40.0% for iTBS and 50.0% for rTMS (p>.60).
- Remission rates were identical across groups at 20.0%.
- Exploratory analyses suggested remitters had higher baseline executive functioning.
Why it matters
Understanding the comparative effectiveness of different stimulation techniques for treatment-resistant depression is crucial for optimizing patient outcomes. This study provides preliminary insights that could guide future research and treatment strategies.
