Are you a retired physical therapist looking for a little extra income? My 81-year-old sister had a stroke in September 2017. She spends a lot of time in bed and is on a feeding tube. In order to prevent further deterioration, she could use exercises on both arms and legs, especially her left side, which is becoming contracted. Pay is negotiable for 2 to 3 times a week for 45 minutes sessions. References. Only serious applicants will be considered.
