Schumacher, who was crowned Formula 1 world champion a total of seven times, suffered a devastating head injury while skiing in the French Alps in 2013.
He was airlifted to Grenoble Hospital where doctors performed two life-saving operations and placed him in a medically induced coma.
Earlier this year it was reported that Schumacher was crying at the sound of his children's voices after starting to recognise faces.
The news in January came just as his family prepared to mark his 46th birthday at their home in Gland, Switzerland, where he has been recovering since June, 2015.
The racing great's family, who are believed to be spending $205,000 a week on his treatment, recently put his Mercedes E55 AMG car up for sale for $180,000.
Schumacher's children have followed in his footsteps and also forged respective careers in sport.
His daughter Gina, 19, won an equestrian European Championship medal this month in Switzerland.
And Schumacher's son Mick, 17, is climbing up the motorsport ladder by winning Formula 4 races.
