A computer scan, performed on Sunday found that the slight subdural bleeding had gone.
His Majesty the King has a good appetite and slept well.
The Royal Household Bureau issued a statement on July 13, saying King Bhumibol experienced twitching in his right hand and a slightly increased pulse rate.
A computer scan revealed minor subdural bleeding. The Monarch was given medications intravenously and has recovered with a normal pulse rate and blood pressure, and no more twitching.
The King has been in residence at Bangkok's Siriraj Hospital since September 2009 when he was hospitalised with fever, fatigue and lung inflammation. He recovered from those symptoms but has remained in hospital ever since for nourishment.
