Rehabilitation will be stepped up for 18-year-old Jason Leung Song-xue, who suffered serious brain damage in the Manila hostage tragedy. The head of the medical team treating Leung said eye movement by the patient could indicate that he knows what doctors want him to do and it might be time to try to let him talk. 'Eye movement is important to determining whether a patient is conscious or not,' Dr Dawson Fong To-sang, head of neurosurgery at Tuen Mun Hospital, said yesterday. On Tuesday night, the team removed 13 bone fragments from Leung's brain and Fong said ultrasound scans showed there were no more big fragments left. He said Leung could now undergo more vigorous rehabilitation, including swallowing his food. Leung's father and two sisters died in the hostage shootings while his mother survived. Fong said the teenager was in a stable condition with his blood circulation normal, and his brain functions were under control. A team of physiotherapists and occupational therapists would now work on helping Leung to move his limbs. Health minister Dr York Chow Yat-ngok and Hospital Authority chairman Anthony Wu Ting-yuk visited Leung yesterday. Wu read out a statement from Leung's mother, Amy Leung Ng Yau-woon, who again thanked Hongkongers for their encouragement and support. She said she was extremely confident of Fong's medical team. 'I believe that Jason will get well one day and thank all of you in person, although the path may be long,' she wrote. Chow said the government would provide support for the mother. Meanwhile, six medical workers who were sent to Manila to help victims come to terms with the death of loved ones yesterday shared their experience in doing relief work in the wake of the tragedy. Recalling three days she spent in Manila after the August 23 crisis, clinical psychologist Rosalie Kwong Lo Suk-yee said accompanying people to identify the bodies of relatives at a morgue was heartbreaking. The senior clinical psychologist with the Hospital Authority was among eight local medical specialists sent to Manila. 'Most of them didn't know their loved ones were already dead,' she said. 'The moment we broke the news to them, they didn't want to accept it. Some had difficulty sitting and standing upon hearing the news.' 'Some insisted on cleaning the corpses themselves. We needed to work with the local medical staff to provide all the arrangements to satisfy their requests.' The group, including neurosurgeons and emergency medical doctors, are part of the authority's 40-strong overseas medical support team which provides relief work in natural disasters and other emergencies. Tong Hon-kuan, of Queen Mary Hospital's accident and emergency department, expressed gratitude for help provided by two Hong Kong doctors who were in Manila attending medical conferences when the tragedy struck. 'They contacted us and volunteered to help before we boarded the plane [to go to Manila],' he said. 'The information provided by them allowed us to know the state of the patients.' Lau Chor-chiu, of Pamela Youde Nethersole Eastern Hospital's accident and emergency department, said the information enabled them to better organise the transfer of seriously hurt victims from the Philippines to Hong Kong for medical follow-up treatment. Jason Leung, Yik Siu-ling - whose lower jaw was shattered by a bullet - and her boyfriend Joe Chan Kwok-chu - shot in both hands - returned to Hong Kong with the medical team.
