The IAAF has formed a group to rule on whether athletes with prostheses can compete in the long jump at the Olympic Games.
Germany's Markus Rehm has a prosthetic right leg and jumped 8.10 metres at the Glasgow Indoor Grand Prix in February, further than any of the able-bodied competitors, and has a personal best of 8.40m - better than Greg Rutherford's leap for the gold medal at the 2012 Olympics in London.
The IAAF's working group will rule on whether artificial limbs provide athletes with an unfair advantage, with a decision set to be announced in June.
Chair of the group and IAAF general secretary Jean Gracia said in a statement: "This group will draw upon extensive knowledge from across disability and able-bodied athletics.
"It is our aim to bring clarity to what is a complex question of technical eligibility as soon as possible so athletes wishing to compete at the European Championships in Amsterdam and at Olympics in Rio are aware of eligibility."
Oscar Pistorius, a double-leg amputee, competed with able-bodied competitors in the 400m and 4x400m relay at London 2012.
