Background and Aim: The aim of this research was to study spinal abnormalities ( kyphosis, lordosis and scoliosis ) and dynamic and static balance in mentally retardation with and without Down syndrome (DS) and relation between them in DS.

Materials and Methods: Thirty mentally retardation with DS (age 13.96 ± 1.77 yr) and 30 mentally retardation without DS (age 14.30±1.96 yr) that selected randomly participated in this study. Modified single balance test for the evaluation static balance and heel-to-toe test for evaluation dynamic balance were used. Continued spinal abnormalities included kyphosis, lordosis and thoracic & lumbar scoliosis were measured by spinal mouse.

Result: The results showed a significant difference between static and dynamic balance, kyphosis and thoracic & lumbar scoliosis in mentally retarded with and without DS . There was a significant relationship between static balance and kyphosis and thoracic and lumbar scoliosis and dynamic balance with kyphosis and thoracic and lumbar scoliosis in DS . There was not a significant relationship between balance and lordosis.

Conclusion: Due to relationship between postural and balance and special needs in mentally retardation particularly Down syndrome, for optimal performance of their daily activities, it should emphasis to recognize the structural profile and prescribe postural corrective programs and improving balance.

Background and Aim: Physical and cognitive performance changes such as impairment in balance and reaction time occur with aging. In according to some studies, these disorders may be delayed by systematic physical activities. This study aimed to investigate the effect of Pilates training on the improvement of balance and reaction time of sedentary adulthood men in Kermanshah city.

Materials and Methods: In this study, 40 sedentary adulthood men, aged (72.15±6.74), selected and divided into two equal groups randomly. These old men lived in Elderly centers in Kermanshah. In order to measure the participants’ balance and reaction time, static balance test stork, timed up and go test and reaction time system was used. Participants participated in a course of 8-week Pilates exercise program such as stretching movements in the muscular joints balance practicing of legs, standing on one foot and deep breathing. After assurance of normality using K-S test, independent t-test was used

  for data analysis.

Results : The results showed in comparison with control group, participation in Pilates protocol, could improve balance and reaction time in elderly men significantly (p<.0.05).

Conclusion: According to results of this study , Pilates training can improve balance and reaction time of the elderly . So to improve the cognitive and motor functions of the elderly , it can be recommended to participate in physical activities such as Pilates training .
