Maria is a resident in a long-term care facility and just celebrated her 85th birthday. She can get around the facility independently using her feet to propel her wheel chair. Her family recently provided Maria a wheel chair that her husband used. Since arrival of the new chair, Maria quit attending activities and has requested meals be brought to her room. What is a potential cause of Maria’s decline in functional mobility?
