Factors affecting walking in a profoundly retarded population.

Area of Science:

• Developmental Pediatrics
• Neurology
• Child Psychology

Background:

• Profound mental retardation presents diverse developmental challenges.
• Understanding motor milestones like walking is crucial for assessing development.
• Previous research has not fully elucidated factors influencing walking in this population.

Purpose of the Study:

• To determine the age of walking onset in children with profound mental retardation.
• To investigate the influence of neurological handicap on walking ability and age.
• To explore the relationship between cognitive level and walking acquisition.

Main Methods:

• Retrospective review of 127 children diagnosed with profound mental retardation.
• Analysis of walking status and age at onset.
• Sub-classification based on the degree of neurological handicap.

Main Results:

• 53% of children achieved walking, with a median age of 30 months.
• Increased neurological handicap correlated with a later age of walking onset.
• Neurological factors were associated with both delayed walking and reduced ambulatory ability.

Conclusions:

• Walking acquisition in profoundly mentally retarded children is influenced by neurological status.
• The minimal cognitive threshold for walking may be lower than commonly believed.
• Early identification of neurological issues is important for supporting motor development in this group.
