Exercises “require multiple thousands of midline crossings in three dimensions” while requiring steady rhythm and auditory function “executed at a pace that naturally results from proper physical techniques.” The brain and the body work together to produce a flow of coordinated movement. Exercises are designed with flexibility using sand- filled bags or racquetballs with the option of performing tasks on a balance board. The customized approach to coordination, rhythm and balance can be increasingly complex or increasingly simplified depending on the presenting impairment. Bal-A-Vis-X can be used with individuals and groups and “promotes focused attention, self-challenge, peer teaching.” Kids typically love Bal-A-Vis-X activities.
