Abstract The postural control system is a complex motor system which is formed based
on an interaction of different dynamic processes and many laboratory techniques
recognize performance disorders using a wide range of neurological signs and
symptoms. The present research aimed to assess the reliability of commonly used
clinical measures of balance and to investigate the effect of age, height, weight and
BMI on performing clinical balance tests. For this purpose, 133 participants (age
range 18-59 yr) who had at least 3 sessions of sport activity per week, participated
in this research. Clinical balance tests included finger-to-nose (FTN), single leg
stance (SLS), tandem stance and time-up-and-go (TUG). The results showed that
the first performance of each three trials was slower. The relationship between
some factors and these balance tests were examined. The results revealed that FTN
and TUG especially TUG test were the most stable measure to assess sports
related concussion

Abstract The aim of the current research was to compare motor development in 3–6-
year-old children from Ahvaz with Denver developmental screening test II. The
methodology of this research was descriptive – survey. The statistical population
consisted of children from Ahvaz and 1044 children aged between 3 and 6 were
selected from Ahvaz kindergartens by cluster random sampling method. Denver
developmental screening test II was used to collect data. Descriptive statistics were
used to compute frequencies and percentile rank to set percentile points. The
finding showed that children from Ahvaz had a delay in all percentile points (25%,
50%, 70% and 90%) in gross movements with regard to Denver test. Also, they had
a delay in all percentile points (25%, 50%, 75% and 90%) in fine movements with
regard to Denver test.
