Firstly, we wanted to know whether, in an 18 month old child referred to a community paediatrician because he cannot walk independently, the most likely outcome is cerebral palsy, a primary muscle disorder, another neurological abnormality, or simply delayed motor development. Secondly, we wanted to know how many children with Duchenne muscular dystrophy present with delayed walking at 18 months.
