Research has been conducted on the effect of diaper perturbation versus unclothed on gait, but there is little research on different diaper perturbations on gait. PURPOSE: The purpose of this study was to examine how physical perturbations (dry and wet diaper and underwear) affected 13 to 19 month old infant’s gait. METHODS: Sixty infants (13-19 month old) were recruited for the study. Five trials for 3 conditions (dry and wet diaper and underwear) were conducted on a GaitRite walkway. Step length (m/step), cadence (steps/s), support base (m) and stance time (sec) were analyzed. A mixed model with repeated measures along with Tukey post hoc test and the Cohen d was used to examine the effect size. RESULTS: For stance time, there was a significant difference between the 13 month old infants with underwear (0.3874±0.0109) and 19 month old infants in wet diaper (0.2761±0.0102). For step length, significant main effect was found for age between 13 month old infants (23.511±.26) and 19 month old infants (31.849±.2432). For support base, significant main effect was found for age between 13 months (12.508±.1732) and 19 months (9.682±.1621) and conditions within the underwear (9.991±.1554) dry diaper (10.618±.1554), and wet diaper (11.245±.1554). For cadence, significant main effect was found for age between 13 months (194.2±3.4988) and 19 months (299.1±3.2728) and conditions within the dry diaper (217.29±2.4255) and underwear (208.08±2.4255). CONCLUSION: It is important to understand the affects perturbation has on infant gait to better equip the infant with diapers that do not affect their natural balance.
