Maybe his hip range of motion is limited that he can't flex to 90 degrees to maintain a sitting posture. You could be right about the core strength as well. Where is your uncle now? Is he in a nursing home? If he is, therapy should evaluate him for a decline in status and mabye look at alternative seating to prevent him from sliding out of the chair.
