We examined the control of motor behavior in relation to age of first diagnosis (AFD; an approximation of age of onset) in schizophrenia. We hypothesized that earlier AFD reflects increased vulnerability to the disorder, vulnerability that may be indexed by elevated levels of motor abnormality. AFD, symptom and demographic features, motor performance on a line drawing task, and the presence and...

The purpose of this study was to investigate the potential long-term association of motor skill proficiency at 6 years of age and self-reported physical activity (PA) at age 26. Direct motor performance data were collected in 1991 with a follow-up study occurring in 1996, and then indirect questionnaires (self-report) administered in 2001 and 2011. In 2011, 17 participants who were identified a...

BACKGROUND Motor proficiency is positively associated with physical activity levels. The aim of this study is to investigate associations between the timing of infant motor development and subsequent sports participation during adolescence. METHODS Prospective observational study. The study population consisted of 9,009 individuals from the Northern Finland Birth Cohort 1966. Motor developmen...

The main aim of the study was to establish the qualitative changes of motor dimensions between the ages of 10 and 14. The sample consists of 550 boys aged 10, 12 and 14. A battery of 26 tests was used for measuring motor abilities. The structure of motor abilities was established with the use of the factor analysis. The results show the emergence of significant qualitative changes of motor dime...

Background: Previous research has found that language and motor skills are closely interrelated developmental areas. This observation has led to questions about the specificity of these domains, and the nature of the associations. In this study, we investigated the longitudinal relationship between language and gross and fine motor performance from 3 to 5 years of age. Methods: We tested the pr...

a motor task performance and imagery show several parallel characteristics. in this study, the effect of a voluntary speed change in mental images of a complex difficult sequence of karate techniques on subsequent motor performance was assessed. 24 male karate volunteers (mean age: 24.58±5.27 years) who were well skilled at performing the sequence movements participated in the pretest. during t...
