Legs Problem

What will be the best possibility for an old folk getting no energy to stand? My ex-colleague told me that her mom's legs having problem with standing. She had already sent her to hospital for several test and medical exam and medicine taken for two weeks but still not much improvement.

She is only fifty plus and now is using crutch whenever she wants to move. My friend did getting quos for electric power wheelchairs but her mom refused to buy one as she claimed that is so inconvenience because they are staying in a small apartment. I did suggest her to go and try for Chinese traditional acupuncture. Hopefully she can gain back both her legs energy soon.
