From Wheelchair to Hands-free Walker for Preschool Children with AAC Needs
We are excited to share the second post in Christine Wright-Ott’s series on promoting hands-free independent mobility in young AAC learners. Christine is an Occupational Therapist and consultant at The Bridge School in Hillsborough California. She authored the chapter “Mobility” in the 4-7th editions of the book, Occupational Therapy for Children. She lectures at universities and conferences including ATIA, Closing the Gap, ISAAC, ISS, and AAC by the Bay.
Support Walker Mobility at the Bridge School
I would like to share with you an innovative hands-free Support Walker Mobility Program developed at The Bridge School, which is a private school for preschool and elementary children with complex communication and physical disabilities located on the district’s public elementary school campus. It is dedicated to ensuring that students achieve full participation in their communities through the use of augmentative & alternative means of communication (AAC), mobility and assistive technology (AT) applications. The Bridge School team recognizes the developmental, social, visual, physical and educational benefits of embedding hands-free mobility into the curricula. Preschool and elementary students participate in self-initiated mobility experiences through the use of hands-free support walkers throughout the school day. Students primarily use the KidWalk support walker at the Bridge School, because it is designed with a large mid-wheel, making it more maneuverable on the school’s uneven playground and over the rubberized mats in the accessible play structure area. It is hands-free, has a small turning radius, provides dynamic vertical and lateral weight shift. The frame does not limit the student’s physical participation in playground activities with peers and students can reach the large wheel to assist in turning and maneuvering it.
Preschool Mobility Experiences & Observations
Preschool students transfer from their wheelchairs or strollers to a support walker to participate in language/music group, activity centers, outdoor time and field trips. Upright standing mobility enables them to experience the same activities as typically developing preschool children: pushing and carrying toys, opening doors, walking over to touch or hug a friend, walking into a playhouse or tent and carrying wood to the campfire during dramatic play. While using the walker, children can orient themselves to sounds and objects, paint with their feet, dance and imitate movements during music/language group, play hide and seek, run, jump, walk to the book shelf to choose a book, sneak up on a friend or push backwards to get away! The speech-language therapists are pleased that mobile preschool students demonstrate more attention, joint engagement and preferred activities, more gesturing, pointing, imitating and an increase in volume and frequency of verbalizations and vocalizations. The occupational therapists observe students in hands-free walkers reaching and touching above shoulder height, and students with cortical visual impairment (CVI) experience more visually directed reach. The students have more experiences to problem solve, discover and demonstrate their personalities. The KidWalk specifically provides some students with the opportunity to experience sensory motor activities not available when sitting: vestibular (spinning), proprioceptive (jumping) and kinesthetic (reaching, bumping and touching), supporting self-regulation. Improved motor control in the trunk and upper extremities has also been observed.
Walking is far more complicated and beneficial for a child’s development than moving from one location to another. Preschool students who experience hands-free mobility at the Bridge School are more engaged with objects and people, discover favorite activities and locations, move close to classroom activities and peers, reach and touch, play games with peers, push toys and participate in dramatic play. Post #3 will describe the support walker program for the elementary students, which includes inclusive physical education, mobility math and access to peers and activities at recess.
