No. It is a CNA or Housekeeping that do “clean up” work. Physical and Occupational therapists work with people who have had muscle or skeletal problems. They do things like teaching them how to walk properly, build muscular strength in both upper and lower body areas. No “dirty work” involved at all and most Community Colleges offer a 2 year program, but be prepared to take a lot of pre-requisites (Anatomy & Physiology, etc).
