I help shower my 91 year old aunt only once a week along with her caregiver. It is starting to kill my back between bending, reaching and twisting. Aunt has advanced dementia but is able to get on her shower bench. She cannot help other than standing and sitting. I sit on the side of the bath tub in front facing her with a handheld shower head for a lot of the washing. Standing is hard for me because she is so short. Any ideas would be appreciated. I stretch before and after and do some basic yoga. Maybe her showers are over? She gets sponge baths on the other days. She enjoys the showers so much and I hate to stop.
