I'm in Mississippi, and it's a very lucrative position in our area. The PTs that I know really enjoy their jobs (both the job itself and the monetary compensation as well).
The occupational therapist is a master's degree program while the physical therapist is a doctorate (3 years post baccalaureate).
I believe that admission process can be very competitive.
I took the following from the Univ. of Miss. Medical Center site:
The physical therapist is a health care practitioner who examines, designs, and implements physical therapy interventions for person of all ages in order to improve or maintain endurance, muscle strength and mobility, and relieve pain and prevent disability due to disease, injury, loss of a body part, or birth defects. The therapist helps the individual prevent problems and overcome disabilities through the use of exercise, education, assistive devices, mobilization, water, cold, electricity, ultrasound and massage. Psychological, sociological and economic factors must be considered while treating an individual. Employment opportunities include hospitals, private practices, rehabilitation centers, home health agencies, industry, research centers, health maintenance organizations, sports medicine centers, nursing homes, community centers, wellness centers, outpatient clinics and school settings. The physical therapy profession offers opportunities for advancement in the areas of education, clinical specialization, management, consultation and research.
