The Difference Between Physiotherapy, OT, and Exercise Physiology

If you've been told you need allied health services — whether through the NDIS, aged care, a workplace program, or your GP — you might be wondering what the difference is between the various professions. Physiotherapy, occupational therapy, and exercise physiology all sound like they involve exercise and movement. So what's actually different?

Here's a straightforward breakdown.

Physiotherapy

A physiotherapist (physio) is a health professional who specialises in the assessment, diagnosis, and treatment of conditions that affect movement and physical function.

Physios treat pain and injury — things like back pain, neck pain, sports injuries, post-surgical recovery, and joint problems. They use hands-on treatment techniques (manual therapy, joint mobilisation, dry needling, massage) alongside exercise prescription to help you recover.

But physio isn't just about injury. Physiotherapists also work in prevention — helping you build strength and mobility to avoid problems in the first place. In aged care, physios deliver reablement programs and falls prevention. In workplaces, they conduct pre-employment assessments and injury prevention programs.

You might see a physio if: you have pain or an injury affecting how you move, you need rehabilitation after surgery, you want to improve your strength or mobility, or you need a falls prevention or reablement program.

Occupational Therapy

An occupational therapist (OT) focuses on helping you do the activities that make up your daily life — what the profession calls "occupations." This includes everything from getting dressed and cooking a meal to driving, going to school, and participating in your community.

Where a physio focuses on your body's movement and function, an OT looks at the bigger picture: can you actually do the things you need and want to do in your life? If not, what's getting in the way — and what can we change?

OTs work across many areas. Under the NDIS, they assess for and arrange home modifications, prescribe assistive technology and equipment, help children with developmental challenges (sensory processing, fine motor skills, school readiness), conduct functional assessments, and help people develop daily living skills.

In aged care, OTs assess residents' ability to perform daily tasks and recommend equipment or environmental changes that support independence.

You might see an OT if: you need home or vehicle modifications, you need assistive equipment, your child has developmental or sensory challenges, you're struggling with daily living tasks, or you need a functional capacity assessment.

Exercise Physiology

An accredited exercise physiologist (EP or AEP) is a university-qualified health professional who specialises in prescribing exercise as medicine. They design and deliver exercise programs specifically for people with chronic conditions, injuries, or disabilities.

The distinction from a physio is subtle but important. While a physio might prescribe exercises as part of treating a specific injury or condition, an exercise physiologist's entire focus is on exercise programming — typically in a gym setting. They're particularly skilled at designing programs for people with complex or chronic health needs where exercise needs to be carefully tailored.

Under the NDIS, exercise physiologists design gym-based programs to improve strength, mobility, cardiovascular health, and overall fitness. In aged care, they deliver individual and group exercise programs that complement physiotherapy.

You might see an EP if: you have a chronic condition and want to improve your health through exercise, you want a structured gym-based program designed for your specific needs, or you're an NDIS participant wanting to build strength and fitness.

Do You Need One, or More Than One?

In many cases, people benefit from more than one type of allied health professional. A physio might treat your pain and mobility issues. An OT might modify your home to make it safer. An EP might set you up with an ongoing gym program. They're complementary, not competing.

At Optimum Allied Health, we offer all three disciplines — plus speech pathology and podiatry — under one roof. This makes coordination simple and means your care team is working together rather than in silos.
