It said that Malala Yousafzai was taken off the ventilator for some time and was later placed back on it.
The ISPR also said that the option to send her abroad for further treatment was being considered.
Earlier, the 14-year old activist's doctors also termed the CT scan and other medical reports of Malala Yousafzai as satisfactory.
Earlier on Saturday, Director General ISPR Maj Gen Asim Bajwa said that Malala Yousafzai's condition was steadily improving and as a result the critically injured 14-year old was now being administered a lower dose of sedatives.
"Movement has been witnessed in Malala's hands and legs which is a positive development," Maj Gen Bajwa said.
He said the doctors have cut down the amount of sedatives being administered to Malala Yousafzai in view of the steady improvement in her health condition. Her condition is satisfactory, he added.
The DG ISPR said the board of doctors has not yet made any decision in connection with taking young Malala abroad. The doctors are constantly busy in taking post-traumatic care of their patient, he said.
Two other girl students wounded with Malala were "also being taken care of at places where they can get best treatment", he said, without elaborating.
Meanwhile the United Arab Emirates has sent an aircraft to fly out Malala Yousafzai who was shot in the head by the Taliban for further medical treatment.
The 14 year old is currently being treated at the AFIC in Rawalpindi.
