Children With Mobility Issues Take Major Strides Thanks To New Tool At Little Light House Thanks to a new tool, children with mobility issues at Tulsa's Little Light House are taking major strides. The school gets to use a high-tech walker for a year after winning a social media contest. Four-year-old Lincoln is all sass and drive. She has Cerebral palsy but in this Trexo Walker, she can go anywhere she wants to go. The Trexo moves a child's legs for them, and you control the system by using a tablet. "This shows how many steps she has taken, so far, she has taken 185. This is her time. Her speed, so it says 15 steps per minute, and we can increase that depending on how she is doing," said Little Light House Occupational Therapist Brooklyn Smith.
