MIBS stands for 'MARBLES In a Bag Syndrome, ' which is a condition that affects children who have difficulty with fine motor skills. It is characterized by an inability to manipulate small objects, such as MARBLES, due to poor coordination and strength in the hands and fingers. This can lead to frustration and difficulty with activities such as playing board games or completing puzzles. Treatment for MIBS includes physical therapy, occupational therapy, and sensory integration therapy.
