Introduction/Aim Psychophysiological disorders and speech pathology is one of
the priority public health problems in the Republic of Serbia. Child?s
growth and development proceed in a particular sequence and course,
depending on individual physiological capacities, quality of neuromuscular
structures and stimuli, which can be significantly affected by the
environment. The development of speech from birth to the adult age is a
result of the interaction of neurocognitive factors that contribute to a
gradual attainment of phonological presentation and motor control abilities.
The aim of the study was to examine the connection between manipulative
manual dexterity, oral practice and lateralization with the development and
speech in children and their potential for the development of prevention
programs. Methods: The sample included 60 children from Belgrade of both
sexes, aged between 5.5 and 7 years. Of these, 30 made up the experimental
group - children with deviations in speech development (articulation
disorders), and 30 the control group - typically developing children from
the general population. The instruments used were the Manipulative Manual
Dexterity Test (Lafayette), Oral Praxis Test, and part of the Test for
assessing lateralisation (auditory, visual, and functional). Results The
hand grip development level is statistically significantly different between
the experimental and the control group (??=21.40, df=3, p<0.01). The
presence of associated involuntary movements statistically significantly
differs between the experimental and the control group examinees (??=10.58,
df=1, p<0.01). Oral praxis statistically significantly differs between the
experimental and the control group (t=2,01, p<0,05). Visual laterality
statistically significantly differs (??=7.56, p<0.05) between the observed
groups. When all predictors are taken into account, significant contribution
to the explanation of the existence of speech pathology (articulation
disorders) is given by the variables: Visual lateralization (OR = 0.38; 95%
CI = 0.179-0.832; p = 0.015) and the level of hand grip development (OR =
0.23; 95% CI = 0.082-0.699; p = 0.009). Conclusion: The hand grip
development level and visual laterality are worse in children with speech
(articulation) impairment and developmental deviations. It is these
indicators of child development that should be used as a guide in designing
the National programmes for developmental assessment and prevention in the
child healthcare system.
