Study investigating walking stability when infants and toddlers carry toys 

Newly walking infants and toddlers (with approximately one year of walking experience) are needed for a study investigating walking stability. Research has shown that infants holding toys in a standing task show an increase in standing stability. Researchers are interested in whether the same is true when infants/toddlers are walking while carrying toys.

Infants and toddlers will engage in a 20-minute free-play session with toys of different sizes and weights and then will be encouraged to walk down a straight pathway carrying toys of different sizes and weights. To measure walking characteristics (e.g., walking speed, step length, step width), children will wear reflective markers on their ankles, so that we can capture their movements using specialized motion capture cameras. 

The project consists of a 40- to 45-minute session at the Life-Span Motor Development Lab located in Lambert Fieldhouse. Newly walking infants (ages 13-14 months) must be capable of walking independently (without any support) for at least 10 consecutive steps. Researchers are also recruiting toddlers (around 24 months) who have been walking for about a year.  Children will receive a Motor Development Lab T-shirt, and parents will receive $5 for travel costs.

Contact Laura Claxton, associate professor of health and kinesiology, at 765-496-2293 or if you are interested in having your child participate or would like more information. IRB#: 1608018080.
