London: After months remaining in coma, Formula One legend Michael Schumacher is yet to recover and reportedly he has lost 25 per cent of his body weight.

Schumacher is almost less than 54 kg as doctors continue with their efforts to revive him from an induced coma.

He suffered severe brain injuries after his head hit a rock head while skiing in French Alps of Meribel, but Schumacher is being massaged daily as he lies immune to treatment at the University Hospital of Grenoble.

Moreover, the massage is not enough to stop muscle shrinkage as Schumacher is yet to respond to treatment given to him by the doctors.
