Occupational therapy (OT) and physical therapy (PT) are often confused for one another. You need to understand the difference so you can figure out which area suits you best as an Allied Health Assistant.
While both occupations involve hands-on rehabilitative work to help people get back to their best selves, they’re different industries with different day-to-day work. Find out what sets them apart to make an informed decision about your future today.
Let’s take a look at the industries as a whole before we dive into what OT Assistants and PT Assistants do differently.
An Occupational Therapist treats the whole person, top to bottom. Whether they’re recovering from injuries or have a disability, OTs help people with daily living.
Unlike in PT, OT does not employ the use of much manual therapy or techniques when dealing with an injury. Instead, they would recommend environmental alterations or introduce assistive equipment to help the patient carry out their daily activities. The focus is on practical solutions to better the quality of life for the patient.
Physical Therapists focus on the patient’s actual impairment from a biomechanical perspective. Physical therapy tries to improve the impairment itself by increasing mobility, aligning bones and joints or lessening pain.
They focus on preventing injuries and can help people avoid surgery or a long-term reliance on medications.
Understanding how OTs and Physios work differently gives you a good foundation for seeing how the assistant roles vary too. But here’s a bit more on what you could be expected to do in each of these roles.
OT Assistants help people regain independence in their daily life. Under an Occupational Therapist's guidance, you'll help people adapt to disabilities, recover from injuries or manage chronic conditions.
Your responsibilities might include:
Helping patients practice daily living skills like cooking or personal care
Setting up adaptive equipment and teaching patients how to use it
Supporting patients during therapy sessions and activities
Assisting with home and workplace assessments
Helping patients develop fine motor skills through therapeutic activities
Supporting families to understand and continue treatment at home
Documenting patient progress and reporting to the supervising therapist
Physiotherapy Assistants work under the supervision of Physiotherapists to encourage patients to follow specific exercise and treatment programs related to injury, illness, or disability-related physical issues.
Responsibilities might include:
Identifying and assessing physical problems of patients
Designing treatment programs
Setting up equipment
Working on exercises with patients
Showing patients how to use mobility aids, canes, and artificial limbs
Applying therapeutic techniques (e.g., heat, cold or massage therapies)
Helping patients prepare for treatment (including helping with dressing and undressing)
Instructing patients and their families in procedures to be continued at home
Although the fields of occupational therapy and physical therapy serve different roles in health care, there is a lot of crossovers between the two.
Educating people on how to prevent and avoid injuries
Informing people about the healing process
Assisting people with improving their ability to perform daily activities through training and education
Improving mobility
In some cases, patients may start with a Physical Therapist and progress to an Occupational Therapist. For example, someone recovering from a severe stroke might work with a PT to build back muscle strength. Later on, that person would see an OT to practice necessary skills the stroke may have impaired such as bathing, dressing, eating and walking.
