My father is strong. He often holds on to side of bed or chair, gets a grip and will not stand up, tho he is still able to some degree. The gait belt doesn't always help and gets him really agitated anyway. I know he has severe arthritis in his hips but he does have pain meds. Otherwise he's in good health. Are there tricks to getting someone to move? Do I quit trying and leave him in bed? I'll need help even rolling him side to side for changing. Suggestions?
