Down syndrome (or trisomy 21) is the most common genetic cause of intellectual disability, occurring in an estimated 1 in 800 births worldwide. Approximately 11,000 people with Down syndrome live in Australia and 250,000 in the USA. Individuals with Down syndrome present with several impairments such as hypotonia, ligament laxity, decreased muscle strength, insufficient muscular co-contraction, inadequate postural control, and disturbed proprioception. Frenkel exercises are a series of motions of increasing difficulty performed by patients to facilitate the restoration of balance and coordination. Frenkel exercises are used to bring back the rhythmic, smooth and movements. In recent years, Swiss Ball has been widely used as a new method of treatment to increase balance, strengthen core region of body muscles, and strengthen muscles that are effective in maintaining posture, coordination, and flexibility. The aim of this recent study is to compare the effects of two different therapeutic techniques i.e Frenkel versus Swiss ball exercises on static and dynamic balance in children with Down syndrome.
