Transcranial Magnetic Stimulation

After noticing that two of the articles mentioned were about Transcranial Magnetic Stimulation, I started getting suspicious. So looked at a few more on Pubmed.

According to Excitatory repetitive transcranial magnetic stimulation induces improvements in chronic post-stroke aphasia.:

We enrolled 8 patients with moderate or severe aphasia >1 year after LMCA stroke.

Sample size 8.

According to Accelerated repetitive transcranial magnetic stimulation (aTMS) for treatment-resistant depression

Patients included 9 men, 5 women with a median age of 51 years (range 20–74 years).

Sample size 14.

According to Revisiting the Backward Masking Deficit in Schizophrenia: Individual Differences in Performance and Modeling With Transcranial Magnetic Stimulation:

Seventeen patients (5 female) were recruited from the New York State Psychiatric Institute (NYSPI) Schizophrenia Research Unit.

Sample size 17.

According to Ten sessions of adjunctive left prefrontal rTMS significantly reduces fibromyalgia pain: A randomized, controlled pilot study.:

We recruited 20 patients with fibromyalgia, defined by American College of Rheumatology criteria, and randomized them to receive 4000 pulses at 10Hz TMS (n=10), or sham TMS (n=10) treatment for 10 sessions over 2weeks along with their standard medications, which were fixed and stable for at least 4weeks before starting sessions.

Sample size 20.

According to Worry Facilitates Corticospinal Motor Response to Transcranial Magnetic Stimulation

The 21 participants were self-identified right-handed males who ranged in age from 18 to 38 years (M=20.33, SD=4.22).

Sample size 21.

According to A bi-directional assessment of the human brain-anorectal axis.

Cortical evoked potentials was assessed following electrical stimulations of anus and rectum with bipolar electrodes in 26 healthy subjects.

Sample size 26.

Finally, according to Noninvasive brain stimulation with high-frequency and low-intensity repetitive transcranial magnetic stimulation treatment for posttraumatic stress disorder.:

In this double-blind, placebo-controlled phase II trial conducted between October 2005 and July 2008, 30 patients with DSM-IV-diagnosed PTSD were randomly assigned to receive 1 of the following treatments: active 20 Hz rTMS of the right DLPFC, active 20 Hz rTMS of the left DLPFC, or sham rTMS.

Sample size 30.

I've looked at nine of these papers. By small-sample standards, I could publish something. By the way, are there any large studies on Transcranial Magnetic Stimulation?
