SPECIAL COMMUNICATION

Walking ability is one of the primary components of human motor function, and interventions aimed at improving walking ability are common in physical therapy, particularly in children. One element encountered in a participatory, or natural, environment is unpredictability, defined as the presence of an unexpected obstacle, stimulus, or alteration of the environmental conditions. Little research has assessed the influence of unpredictability on biomechanical adaptations to walking in children who are developing typically or children with motor disabilities. A variety of impairments may result in an inadequate response to unpredictability, and we propose that there may be a relationship between response to an unpredictable visual cue and mobility-based participation.

We believe that a child's ability to respond to unpredictable circumstances while walking may provide additional information regarding participation limitations that have yet to be captured in existing clinical gait tools.
