Background. The preschool years constitute a critical period during which significant changes are experienced in the acquisition of locomotor skills due to maturation of the nervous system. Our aim was to investigate the developmental parameters and physical fitness in preschool children with Minor Neurological Dysfunction (MND).

Methods. The study was carried out in 212 preschool children without any known health problems. Sociodemographic characteristics of children were recorded. Denver Developmental Screening Test (DDST) II, Touwen Neurological Examination, and Preschool Physical Fitness (PREFIT) test battery were used to assess developmental parameters, neurological status, and physical fitness, respectively.

Results. There was a statistical difference in the physical fitness and developmental parameters in preschool children with MND compared with healthy peers (p < 0.05). There was also a relationship between physical fitness and developmental parameters (p < 0.05).

Conclusions. Early identification of problems in developmental parameters and physical fitness in preschool children with MND might help to implement early supportive physiotherapy and rehabilitation.
