I'm not a therapist, but I know exercise (lifelong practitioner); I just don't know it for a weakened person. I'm going to be working with a woman of 84, diabetic and with a mild heart condition. She's actually quite healthy but has been allowed to spend all her time sitting or lying down. She can shuffle along with her walker for short distances, but she's heading for true invalidism if she doesn't get turned around. That will be bad for everybody, but especially for her.
Any advice, experience, tips, success stories, horror stories, source recs, etc. would be most welcome.
