The hours and days that physical therapist assistants and aides work vary with the facility and with whether they are full- or part-time employees. Many outpatient physical therapy offices and clinics have evening and weekend hours, to help coincide with patientsí personal schedules. About 30 percent of all physical therapist assistants and aides work part time.
Physical therapist assistants and aides need a moderate degree of strength because of the physical exertion required in assisting patients with their treatment. In some cases, assistants and aides need to lift patients. Constant kneeling, stooping, and standing for long periods also are part of the job.
