Preventive measures could include moving the bedroom downstairs to minimize trips up and down stairs, having a non-medical senior care service help with laundry if laundry is in the basement (again to minimize the need to travel up and down stairs, especially if arms are full with a laundry basket), picking up scatter rugs to minimize tripping over them, getting physical therapy for strength and balance, or getting a personal emergency device such as Lifeline and wearing it! You’d be surprised at how many seniors have personal emergency systems in place, but don’t wear their pendants, bracelets, or belt clips!
