| Crawling Style | Rate (cycles/s) | Stance | Swing | Stance | Swing |
| Standard | 1.2 ± 0.3 | 0.65 | 0.36 | 0.81 | 0.19 |
| Hands and feet | 1.2 ± 0.3 | 0.94 | (0.06) | 0.87 | 0.13 |
| Mixed | 0.8 ± 0.3 | 0.94 | 0.06 | 0.80 | 0.20 |
| Creeping | 0.6 ± 0.2 | 0.69 | 0.31 | 0.88 | 0.12 |
| Scooting | 1.2 ± 0.3 | 1.04 | (0.04) | — | — |
Values for crawling rate are means ± SD; steps were pooled for each crawling style. Regression lines are from linear regression of duration of phase (stance or swing) vs. duration of cycle. Parentheses indicate nonsignificance of regression line. Scooters did not use arms in stance and swing.
