The Black Stars captain took part in a full training session for club Chelsea on Wednesday as he prepares to report for international duty by joining up his colleagues in Angola before the start of the competition on Sunday.
Essien had been allowed to stay on Chelsea as he recuperated from a hamstring injury in a Champions League match against Apoel last month.
Ghana's opening Group B game is against Togo on Monday and it will be followed by the clash against Ivory Coast four days later before the final match with Burkina Faso.
