Abstract
Purpose:
Down syndrome is the most common chromosome abnormality and the most common genetic cause of intellectual disabilities in humans. The aim of this study was to investigate the effect of a selective combined training program on motor performances, balance and muscle strength in boys with Down syndrome.
Methods:
Twenty boys with Down syndrome aged ranged from 12 to 20 years were randomly assigned either into an experimental group (n=10) or control group (n=10). Subjects in the experimental group underwent combined training program for 45 and 60 minutes per day, 3 times a week, for 8 weeks. To evaluate the muscle strength and balance in subjects with Down syndrome, muscles force was measured with handheld dynamometer (MMT, North coast, USA) and balance with Sharped Romberg (r=0.90-0.91) with eyes both being open and close. Two-Way ANOVA with Repeated Measures was used to analyze the data (p≤0.05).
Results:
ANOVA with repeated measures showed that knee flexion strength (p≤0.05), Knee extension(p≤0.05),hip flexion (p≤0.05), hip extension (p≤0.05), ankle plantar flexion (p≤0.05), ankle dorsiflexion (p≤0.05), and also static balance with eyes open (hard surface) (p≤0.05) ,static balance with eyes being close (hard surface) (p≤0.05), static balance with eyes being open (the software) (p≤0.05), static balance with eyes being close (the software) (p≤0.05) of the intervention group was significantly better than the control group.                
Conclusion:
A combined strength and proprioceptive training improves postural balance in children with DS. This could be due to the enhancement in muscle strength and proprioceptive input integration.
