My Mom (87) keeps bending forward at the waist, pretending to pull up socks. She had hip surgery (not replacement), 4 yrs. ago. Is this normal?

Are you saying she's actually pretending to put socks on, or that that's what it looks like she's doing?

In either case, I would get her in to see her doctor, as this seems like a big behavior change.

ipanda, you need to take your Mom to see her primary doctor and let him/her make the next suggestion. Something must be bothering your Mom to make her keep bending forward at the waist.

Does your Mom use a cane? Is she bending toward the side where she uses the cane? My Mom is doing that now, so it could be osteoporosis.
