According to the Beeb, Safura Abdool Karimm, who has played on the kit three times herself, interviewed 120 of her classmates about medical problems they had when playing the games too long.
"PlayStation Thumb" is similar to Repetitive Strain Injury (RSI) and its symptoms include blisters, numbness and tingling, mainly in the thumb.
The article was accepted by South African Medical Journal's deputy editor, Professor JP van Niekerk, who said Ms Karim's work would be listed on the Index Medicus, an international registry of medico-scientific articles, "so the world can see this and cite it".
The study found that eight boys and seven girls in the survey complained of symptoms such as redness, tingling and blisters.
Karim told the Beeb she didn't own a PlayStation because they were a "waste of time", she was too busy writing papers for medical journals anyway. More at the BBC, here. ยต
