A 13-year-old girl has become the youngest author to be published in South Africa's main medical journal for her research on "PlayStation thumb".

Safura Abdool Karim interviewed 120 of her former schoolmates for a science project about whether they suffered problems after playing computer games.

Symptoms of "PlayStation Thumb" include blisters numbness and tingling, mainly in the thumb, she wrote.

She said the condition is similar to Repetitive Strain Injury (RSI).

"Although RSI is not new, in the past it occurred mainly among adults," she said.

"Today computers and computer games are creating new medical problems, such as PlayStation thumb, which are becoming common in children."
