Mom has a hard time putting one foot in front of the other. She walks so slow and has no sense of balance. She refuses to use her cane or walker. When we take her out I have to hang on to her to keep her steady. She does live alone. She has furniture in her house positioned where she can hang on to something every step of the way. Mom is 89. I worry about her falling. What typically causes this? She thinks it will get better.
