Rebound Therapy on Ventilatory Functions in Down Syndrome

Effect of Rebound Therapy on Ventilatory Functions in Children With Down Syndrome. A Randomized Controlled Trial

The purpose of this study is to examine the effects of rebound therapy on ventilatory functions in children with Down Syndrome.

Down syndrome (DS) is one of the common congenital anomalies associated with a high rate of various medical disorders including congenital cardiac defects, visual and auditory affection, musculoskeletal system, and autoimmune disorders. Respiratory involvement is common in DS and is a leading cause of death. Rebound therapy from quality of mini trampoline provides all benefits of other aerobic exercise without the stress impact usually associated with vigrous activity. Several studies support the use of rebound therapy among different areas while, there is no research conducted on ventilatory functions in children with Down Syndrome. Hence, there is need to study the effect of rebount therapy on ventilatory functions in children with Down Syndrome.

Fourty children with Down syndrome (based on power analysis) from both sexes (9-13 years) will be recruited from different schools of special education. They will be divided randomly into control group (20 children) and study group (20 children). The control group will receive a chest physical therapy protocol that included respiratory exercises and incentive spirometer training. The study group will receive a rebound therapy using mini trampoline.
