The WeeFIM instrument (32) is a pediatric functional independence in children aged 2 - to 6 years, contains 18 items across the domains of self-care (6 self-care and 2 bowel and bladder management items), mobility (3 transfer and 2 locomotion items), and cognition(2 communication and 3 social cognitive items). Self-care items examine how independent a child is in eating, grooming, bathing, upper body and lower body dressing, and toileting. The mobility domain includes chair/wheelchair, toilet and tub/shower transfers, and locomotion with respect to walking, use of wheelchair or crawling and going up/down stairs .. The cognition domain examines how well a child expresses his/herself and understands communication. This domain also comprises social interaction (e.g., skills related to getting alone and participating with others in play situations). In addition, problem solving is addressed by assessing a child's ability to solve problems of daily living and memory (e.g., remembering daily routines, recognizing familiar people). Each item is rated on a 7 - point ordinal scale ranging from 7(complete independence) to 1 (total assistance). A moderate disability is defined as scores falling between (50 to 75), whereas a severe disability encompasses scores below 50 and would include children who are essentially fully dependent in self-care and mobility. The WeeFIM is a 7 - level criterion-specific ordinal scale as the following: Therefore the minimum score is 18 with maximum of 126, in self-care, the range of score are 8 to 56,in motor, the range of scores are 5 to 35,in cognition,
