About

Infantile hemiplegia due to brain injury is associated with poor attention. Left-sided infantile hemiplegia affects the learning and acquisition of new skills. This study is aiming to improve the Selective visual attention (SVA) through transcranial direct current stimulation (tDCS) in children with Left-sided infantile hemiplegia .

Full description

Infantile hemiplegia (IH) refers to brain injuries that occur before or at birth and lead to hemiplegia/ total paralysis of one side of the body, including the face, arm and leg. The IH is quit rare condition and occurs in 1 in 1000 live births. however, the condition is reported to cause functional and cognitive disability. Children with IH suffer from poor attention particularly visual attention, that is essential to be understand the written language. A focused reading is essential in learning and children with IH possess moderate intelligence and attend school.

Transcranial direct current stimulation(tTCS) is a novel intervention that use small amplitude electrical currents to stimulate the essential areas of the brain through surface electrodes placed on the corresponding areas of the brain.

The eligible children were divided into two groups. one group received tDCS with visual attention activities and the second group received sham tDCS with similar activities. The effect will be assessed before and after with Strops-color testing and a academic reading test.

The experiment intends to explore the affect of tTCS on visual attention span among children with Left-sided infantile hemiplegia.
