Participants demographic information, behavioural results and TMS motor thresholds
| Measures | Stuttering | Controls | Difference |
|---|---|---|---|
| n | 13 | 13 | n/a |
| Females (n) | 4 | 4 | n/a |
| Age in years | 34.5 (7.8) | 30.2 (12.0) | P = 0.3 (n.s.) |
| Age of stuttering onset in years | 4.0 (2.1) | n/a | n/a |
| SSI-3 overall score | 23.5 (8.9) | n/a | n/a |
| % Stuttered disfluencies | 7.6 (6.0) | 0.3 (0.2) | P = 0.001 |
| Handedness | 75.2 (43.6) | 87.6 (17.8) | P = 0.35 (n.s.) |
| Education* | 3 | 4 | P = 0.09 (n.s.) |
| Motor threshold left hemisphere | 41.9 (7.3) | 37.6 (3.2) | P = 0.07 (n.s.) |
| Motor threshold right hemisphere | 42.6 (5.6) | 37.7 (3.4) | P = 0.01 |
*Education is reported as median, group differences were quantified by Mann-Whitney test.
SSI-3 = Stuttering Severity Instrument, third edition; % stuttered disfluencies = stuttered syllables occurring per 100 syllables; n.s. = not significant.
