These are just little Workouts for the Left and Right Hemisphere based on whether your child is having Left or Right brain weakness. Bear crawls help develop body awareness, improve coordination and motor planning, and build strength in the trunk and upper body. Throwing weighted objects like medicine balls can increase core strength and balance and help improve coordination. It may also have therapeutic benefits and can stimulate brain centers responsible for short-term memory. In a study published in Research in Autism Spectrum Disorders, the authors found that movements similar to those exhibited by those with autism may help provide needed feedback to the body. This may reduce repetitive behaviors such as arm flapping or clapping. Arm circles are a great upper-body exercise that helps increase flexibility and strength in the shoulders and back and can be done anywhere with no equipment.
