Physiotherapy is a regulated health profession that restores, maintains, and maximizes your movement, strength, and physical function. Physiotherapists assess how your body moves, find the root cause of the pain or limitation, and treat it with hands-on manual therapy, prescribed exercise, and education so the problem does not keep returning. Below we explain what physiotherapists actually do, how the treatment works, the techniques and conditions involved, what happens at a first appointment, how many sessions people usually need, and how access and coverage work in Ontario.

What Is Physiotherapy?

Physiotherapy is treatment that restores, maintains, and maximizes a person’s mobility, function, and wellbeing through physical rehabilitation, injury prevention, and guided exercise. The treatment is delivered by a physiotherapist, a licensed practitioner who studies the science of human movement and is trained to diagnose movement dysfunction across the musculoskeletal, nervous, cardiopulmonary, and integumentary systems, as Cleveland Clinic sets out in its patient reference on the profession.

Movement dysfunction is the thread that runs through every case we see. A shoulder that will not lift overhead, a knee that gives way on stairs, a lower back that seizes after an hour at a desk: each one is a movement problem with a mechanical and neurological cause behind it. Finding that cause is why physiotherapy starts with assessment rather than treatment.

Assessment separates physiotherapy from general exercise advice. The College of Physiotherapists of Ontario describes physiotherapists as practitioners who pinpoint an injury’s root causes and focus on both prevention and rehabilitation, which is exactly how we structure a plan: identify the driver, treat the driver, then build capacity so the tissue tolerates normal life again.

What Is the Difference Between Physiotherapy and Physical Therapy?

There is no difference between physiotherapy and physical therapy. The two terms describe the same profession and the same treatment. Canada, the United Kingdom, Australia, and most of Europe use physiotherapy, while the United States more commonly uses physical therapy. Cleveland Clinic lists the two names interchangeably in the same patient article.

The same profession carries a single scope wherever it is named: assess movement, diagnose the dysfunction, treat it, and prevent recurrence. Prevention matters as much as treatment, because a knee that was rebuilt but never retrained simply fails again the next season.

What Does a Physiotherapist Do Exactly?

A physiotherapist does three things: assesses how you move, builds a treatment plan for your specific injury and goals, and teaches you the movement and strength work that prevents the problem from coming back.

Assessing how you move means measuring it, not eyeballing it. We take a full health history, then test joint range of motion in degrees, grade muscle strength, check joint play and end-feel, screen the relevant nerves, and watch you perform the actual task that hurts, whether that is a squat, a stair step, a reach, or a running stride. Watching the painful task is what usually exposes the real driver, because pain often shows up several joints away from the tissue that is failing.

The failing tissue then sets the plan. A treatment plan lists what we will do in clinic, what you will do at home, how often you will come in, and what measurable change we expect by which week. Measurable change is what we reassess against, so the plan gets adjusted with evidence rather than guesswork. In our Markham clinic, our physiotherapists Rachel Marie Tan and Timothy Kwan both work this way, and both are registered with the College of Physiotherapists of Ontario.

Registration matters to you as a patient because it guarantees the person treating you is accountable to provincial standards for safety, consent, record keeping, and competence. Consent is part of that standard, which is why the first visit includes a plain explanation of the findings before any treatment begins.

What Should You Tell Your Physiotherapist at the First Visit?

Tell your physiotherapist when the problem started, what makes it worse, what makes it better, what you have already tried, any imaging or surgery you have had, and the specific activity you want to get back to. The specific activity is the most useful detail of all, because “I want to lift my toddler without my back locking” produces a sharper plan than “my back hurts.”

A sharper plan also depends on the awkward details. Night pain, numbness, tingling, weakness, bladder or bowel changes, unexplained weight loss, and fever all change how we proceed, and none of them are things to leave out.

How Does Physiotherapy Work?

Physiotherapy works by loading tissue in a controlled, progressive way so it remodels and gets stronger, by restoring normal joint and soft tissue mechanics through hands-on techniques, and by retraining the nervous system to stop guarding a movement it has learned to treat as dangerous.

Controlled loading is the engine of recovery. Tendon, muscle, bone, and cartilage all adapt to the demand placed on them, so a tendon that is given graded, repeated load rebuilds its capacity to handle that load, while a tendon that is rested completely loses capacity and fails again the moment normal life resumes. The dose has to be right: too little produces no adaptation, too much irritates the tissue further.

Getting the dose right is the clinical skill, and it is why prescribed exercise rehabilitation outperforms generic gym programming for an injured body. The evidence sits behind it. A meta-analysis of 77 randomized controlled trials covering 6,472 participants with knee and hip osteoarthritis found that exercise therapy produced significant benefits for pain, function, physical performance, and quality of life at eight weeks, with effect sizes of 0.56 for pain and 0.50 for function.

Function improves for a second reason that has nothing to do with tissue strength. Persistent pain sensitizes the nervous system, so the brain starts producing protective pain and muscle guarding at loads the tissue could easily handle. Graded exposure to those loads, paired with clear education about what is actually happening, turns that protective response down. This is why we explain findings in plain language instead of handing over a diagnosis and a sheet of exercises.

What Are the Main Types of Physiotherapy?

The three main types of physiotherapy are musculoskeletal physiotherapy, neurological physiotherapy, and cardiorespiratory physiotherapy, with pelvic health and paediatric physiotherapy recognized as further areas of practice.

Musculoskeletal physiotherapy is the branch most people encounter. It covers bones, joints, muscles, tendons, and ligaments, and it handles back pain, neck pain, sports injuries, tendinopathy, arthritis, and post-surgical orthopedic recovery. Neurological physiotherapy addresses movement loss caused by the nervous system, including recovery after stroke or spinal cord injury and symptom management in Parkinson’s disease and multiple sclerosis (MS). Cardiorespiratory physiotherapy supports recovery after a cardiac event and helps people manage chronic breathing conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Each branch draws on the same technique set, applied at different intensities and for different goals. Exercise is by far the most used of them: a prospective study of 297 physiotherapists managing knee osteoarthritis, published in BMC Health Services Research, found that 98 percent used exercise as a core treatment and 68 percent delivered structured patient education alongside it. The remaining techniques support that core work, and some of them, like medical acupuncture and laser therapy, are used to reduce pain enough that the active work becomes possible.

What Is Manual Therapy in Physiotherapy?

Manual therapy in physiotherapy is hands-on treatment where the physiotherapist uses their hands to mobilize joints, release soft tissue, and improve movement in a restricted area. Joint mobilization restores the small gliding movements a stiff joint has lost, while myofascial release and soft tissue work reduce tone in muscle that has been guarding for weeks.

Reduced guarding creates a window where movement is easier and less painful, and that window is what we use to load the tissue properly. Manual therapy on its own rarely holds; manual therapy followed immediately by exercise does. The table below sets out how the main techniques differ.

Technique	What it does	How it works	Typically used for
Therapeutic exercise	Rebuilds strength, endurance, and control	Progressive mechanical load drives tissue remodelling and motor learning	Nearly every case, from tendinopathy to post-surgical recovery
Manual therapy and joint mobilization	Restores lost joint movement	Graded hands-on pressure improves joint glide and reduces protective muscle tone	Stiff shoulders, necks, backs, and post-immobilization joints
Soft tissue and myofascial release	Reduces muscle tension and tenderness	Sustained manual pressure lowers muscle tone and improves tissue mobility	Chronic neck and back tightness, repetitive strain injuries
Transcutaneous electrical nerve stimulation (TENS)	Dampens pain signals	A low-level electrical current stimulates sensory nerves and reduces pain perception	Short-term pain relief so active treatment can begin
Ultrasound therapy	Warms deep tissue	High-frequency sound waves increase local blood flow to the injured area	Localized soft tissue injuries
Heat and cold therapy	Manages pain and swelling	Temperature change alters local blood flow and nerve conduction	Acute flare-ups and post-exercise soreness
Medical acupuncture	Reduces pain and muscle tone	Fine needles stimulate nerve endings and trigger local circulatory and pain-modulating responses	Persistent muscular pain and myofascial trigger points
Patient education	Changes behaviour and expectations	Accurate information reduces fear-driven guarding and improves adherence	Chronic pain, recurring injuries, return-to-sport planning

What Conditions Does Physiotherapy Treat?

Physiotherapy treats musculoskeletal injuries, neurological conditions, cardiorespiratory conditions, and post-surgical recovery. Cleveland Clinic notes that physical therapy can work on any body system that controls movement, which includes the musculoskeletal, nervous, cardiopulmonary, and integumentary systems. The conditions below are the ones we see most often:

• Musculoskeletal: low back pain, neck pain, osteoarthritis, frozen shoulder, rotator cuff tears, tennis and golfer’s elbow, plantar fasciitis, sciatica, herniated discs, and sports injuries such as sprains, strains, and anterior cruciate ligament (ACL) tears.
• Neurological: mobility loss after stroke, spinal cord injury, traumatic brain injury, Parkinson’s disease, and multiple sclerosis.
• Cardiorespiratory: rehabilitation after a heart attack, and breathing and endurance management in asthma and COPD.
• Post-surgical: knee and hip replacement, ACL reconstruction, rotator cuff repair, spinal surgery, and fracture recovery.
• Pelvic health: bladder and bowel symptoms, pelvic pain, and postpartum recovery, treated through pelvic floor therapy.
• Workplace and accident related: repetitive strain injuries, desk-related neck and shoulder pain, whiplash, and motor vehicle accident recovery.

Can Physiotherapy Help With Chronic Pain?

Yes, physiotherapy helps with chronic pain, and it is one of the most effective non-invasive options available for it. Chronic pain usually involves a mix of movement dysfunction, muscle imbalance, nervous system sensitization, and avoidance habits built up over months, and each of those responds to a different part of the treatment plan.

Avoidance habits are often the hardest piece and the most rewarding to change. A national register study of 6,245 patients in a supervised exercise and education programme, published in the International Journal of Environmental Research and Public Health, found the proportion reporting low or no physical activity fell from 43 percent to 22 percent, and more than 80 percent were still using what they had learned two years later.

Why Would Someone Need Physiotherapy?

Someone needs physiotherapy when an injury, surgery, health condition, or long-term movement pattern has reduced their strength, mobility, or ability to do daily activities without pain. WebMD lists the most common triggers as injury, surgery, prolonged illness, chronic conditions, ageing, major health events such as stroke or heart attack, and performance goals.

Performance goals bring in a group most people do not associate with rehabilitation. Runners chasing a first half marathon, basketball players managing recurring ankle instability, and desk workers who want to lift again without their back flaring all use physiotherapy to build capacity rather than repair damage. Building capacity sometimes involves addressing the ground up, which is where custom orthotics support a plan for foot and lower limb mechanics.

Who Can Benefit From Physiotherapy?

People of every age benefit from physiotherapy, from infants with developmental movement delays to older adults working on balance and fall prevention. The NHS states plainly that people of all ages can have physiotherapy, including children and older people.

Older adults gain the most from the balance and strength side of it, because falls are largely a strength, reaction time, and confidence problem rather than an unavoidable consequence of age. Confidence is trainable, and it is trained by doing the thing that feels risky under supervision until it stops feeling risky.

What to Expect When You Go to a Physiotherapist

When you go to a physiotherapist, expect a detailed history, a full movement and strength assessment, a clear explanation of the findings, an agreed treatment plan, hands-on treatment, and a home exercise programme, usually all in the first visit. Your first appointment with us runs roughly 45 to 60 minutes. The sequence goes like this:

1. Health history. When the problem started, how it behaves through the day, previous injuries, imaging, surgeries, medications, work demands, and your goal.
2. Physical assessment. Joint range of motion measured in degrees, muscle strength graded, joint play and end-feel tested, neurological screening where symptoms warrant it, and observation of the movement that provokes your symptoms.
3. Findings explained. What is driving the problem, what is not causing it, and what the tissue is realistically capable of right now.
4. Goal setting and plan. Visit frequency, expected timeline, and the specific milestones we will reassess against.
5. Treatment. Manual therapy, mobilization, soft tissue work, exercise, or a supporting modality, chosen for what the assessment found.
6. Home exercise programme. Two to five exercises with sets, repetitions, and frequency, because the work between visits is where most of the adaptation happens.
7. Reassessment. Measurements repeated at agreed intervals so the plan is adjusted against results rather than assumption.

Adjusting against results is what keeps physiotherapy treatment honest. If a measurement has not moved by the point we said it would, the plan changes.

What Should You Wear to a Physiotherapy Appointment?

Wear loose, comfortable clothing you can move in, and bring supportive shoes, because you will be asked to walk, bend, squat, and reach during the assessment. Shorts help for knee, hip, and ankle problems, and a tank top or sports top helps for shoulder and neck problems, since we need to see and feel the joint we are assessing.

Seeing the joint does not mean removing more clothing than you are comfortable with. Draping, gowns, and alternatives are always available, your consent is required before any hands-on treatment, and you can decline or stop any technique at any point.

How Long Does a Physiotherapy Session Last?

A physiotherapy session lasts about 45 to 60 minutes for an initial assessment and roughly 30 to 45 minutes for follow-up visits. The initial visit runs longer because the history and assessment take up a substantial share of it before any treatment begins.

Follow-up visits are shorter because the assessment narrows to reassessment: check the measurements, progress or regress the exercise dose, treat, and adjust. Adjusting the dose each visit is what produces steady progress instead of a plateau.

Does Physiotherapy Hurt at First?

Physiotherapy does not usually hurt at first, though some techniques and exercises cause temporary discomfort, and mild soreness for 24 to 48 hours after a session is normal. Mild soreness after loading an under-used muscle is the same soreness anyone feels after a new workout, and it is a sign of adaptation rather than damage.

Damage feels different. Sharp pain during a technique, symptoms that spread down a limb, or soreness that lasts several days and leaves you worse than before all mean the dose was too high. Telling us immediately is the fastest way to fix it, because we adjust intensity within the same session.

What Should You Do After a Physiotherapy Session?

After a physiotherapy session, keep moving gently, drink water, do your prescribed home exercises on the schedule you were given, and avoid testing the injury with a hard workout on the same day. Gentle movement keeps the joint from stiffening back up while the treatment effect is still present.

The treatment effect fades within a day or two, which is exactly why the home programme exists. Two or three short sessions a week done consistently beat one heroic effort the night before your next appointment.

How Many Physiotherapy Sessions Do You Need?

Most people need six to ten physiotherapy sessions over six to twelve weeks, though the number depends on the injury, how long it has been present, and your recovery goal. Acute, simple problems often resolve in three or four visits; long-standing problems and post-surgical rehabilitation run longer and follow the surgeon’s protocol.

The twelve-week window is not arbitrary. The meta-analysis of 77 randomized trials found exercise effects peaked at around two months, which matches what a well-dosed plan looks like in practice: meaningful change inside the first few weeks, consolidation through weeks six to twelve. Your first movement assessment is where you get a realistic estimate for your own case, and that estimate is revised at every reassessment.

Does Physiotherapy Actually Work?

Yes, physiotherapy works, and the strongest evidence sits behind exercise-based treatment for musculoskeletal pain. A 2024 Cochrane review of land-based exercise for knee osteoarthritis found exercise improved physical function by 11.3 points and pain by 8.7 points on a 0 to 100 point scale compared with placebo or attention control.

Those numbers are averages across large mixed populations, which understates what a targeted, supervised, progressively dosed programme achieves for an individual. Supervision and progression are the two variables clinics control, and they are the difference between a generic exercise sheet and a plan.

A plan also travels. A British Journal of Sports Medicine systematic review of digital physiotherapy for knee osteoarthritis found video-conferenced and app-based programmes produced significant reductions in pain and improvements in physical function, with the strongest results where the programme included individualized exercise. Individualized exercise is the common factor in all of this evidence, which brings us to the practical side: how you actually get started.

Do You Need a Referral to See a Physiotherapist in Ontario?

No, you do not need a referral to see a physiotherapist in Ontario, because physiotherapists are primary care practitioners and you can book directly. The College of Physiotherapists of Ontario confirms that a doctor or nurse practitioner may refer you, but you can also seek physiotherapy services independently.

Booking independently does come with one thing worth checking first. Some extended health policies require a physician referral for reimbursement even though the profession itself does not, so a quick look at your policy wording before your first visit in Markham saves an unpleasant surprise at claim time.

Is Physiotherapy Covered by Insurance?

Physiotherapy is covered by most extended health benefit plans in Canada, and it is also covered under Workplace Safety and Insurance Board (WSIB) claims and motor vehicle accident insurance where those apply. Coverage is usually expressed as an annual maximum, sometimes with a per-visit cap.

Caps and maximums are worth knowing before you plan a twelve-week course of care. We direct bill most major insurers, so in most cases you only handle any remaining balance rather than paying the full amount and waiting on reimbursement. WSIB claims and motor vehicle accident claims are handled the same way, with the insurer billed directly.

What Is Better, a Chiropractor or a Physiotherapist?

Neither is better overall, but they suit different problems: a physiotherapist is the stronger choice for rehabilitation, post-surgical recovery, and rebuilding strength and function, while a chiropractor is the stronger choice for spinal and joint mechanics addressed through adjustment.

Adjustment and rehabilitation are not competing approaches, they are different tools. Physiotherapy leans on assessment, graded exercise, and manual therapy across the whole body; chiropractic care leans on joint manipulation and the relationship between the spine, joints, and nervous system. Both are regulated primary care professions in Ontario, and both can be accessed without a referral.

Many of the people we see benefit from both, which is why our physiotherapists and chiropractors work under one roof and coordinate on the same case. Coordination matters most when the problem is stubborn, because a joint that keeps stiffening and a muscle that keeps failing to hold it are two halves of the same problem.

What Is a Red Flag in Physiotherapy?

A red flag in physiotherapy is a symptom that suggests a serious underlying medical condition rather than a musculoskeletal problem, and it prompts your physiotherapist to refer you to a physician rather than continue treatment. Screening for these is a standard part of every initial assessment.

The screening looks for a defined set of signals: unexplained weight loss, fever or night sweats, unrelenting night pain that is unchanged by position, progressive neurological weakness, saddle numbness, new bladder or bowel changes, a history of cancer with new bone pain, or significant trauma in someone with reduced bone density. Any of these means we make the appropriate referral immediately, and it is one of the reasons assessment always comes before treatment.

Frequently Asked Questions

Is Physiotherapy Covered by OHIP?

Physiotherapy is covered by OHIP only for specific eligible groups at designated publicly funded clinics, hospitals, and long-term care settings. Eligibility is generally limited to people aged 65 and over, people aged 19 and under, and those who had a recent hospital stay related to the condition or who receive certain social assistance benefits. Everyone else uses extended health benefits, WSIB coverage, motor vehicle accident insurance, or private payment.

What Is the Difference Between Physiotherapy and Massage Therapy?

The difference between physiotherapy and massage therapy is that physiotherapy assesses and rehabilitates movement dysfunction through exercise, manual therapy, and education, while massage therapy treats soft tissue directly to reduce tension, improve circulation, and relieve pain. Physiotherapy diagnoses and builds a recovery plan; massage therapy is a soft tissue treatment that often supports that plan. Many people use both in the same course of care.

Can You Do Physiotherapy at Home?

You can do physiotherapy at home, and the prescribed home exercise programme is a core part of nearly every treatment plan. Home work is where most of the strength and tissue adaptation actually happens, because two or three short sessions a week produce far more loading than one clinic visit. The in-clinic visits handle assessment, hands-on treatment, and progression of the programme.

How Soon After Surgery Can Physiotherapy Start?

Physiotherapy usually starts within one to two weeks after most orthopedic surgeries, though the exact timing follows your surgeon’s protocol. Some procedures begin with prehabilitation before surgery, which improves post-operative outcomes by entering the operation with better strength and range of motion. Bring your post-operative instructions to the first visit so the timeline can be matched to the protocol.

Is Virtual Physiotherapy Effective?

Virtual physiotherapy is effective, particularly for exercise-based programmes. A British Journal of Sports Medicine systematic review found video-conferenced and app-based physiotherapy produced significant reductions in pain and improvements in physical function, with the best results when the programme included individualized exercise. Hands-on techniques still require an in-person visit, so virtual care generally works best as part of a plan rather than a full replacement.

Is Physiotherapy Safe During Pregnancy?

Physiotherapy is safe during pregnancy and is commonly used for pelvic girdle pain, low back pain, and postpartum recovery. Treatment is adapted to each trimester, with positioning, load, and technique selection adjusted as pregnancy progresses. Pelvic floor assessment and pregnancy care are often used alongside it for bladder symptoms and postpartum return to activity.

The Bottom Line

Physiotherapy is assessment-led treatment that restores movement, strength, and function, and it works through three connected mechanisms: progressive loading that rebuilds tissue capacity, hands-on techniques that restore joint and soft tissue mechanics, and education that turns down a nervous system stuck in protection mode. It treats musculoskeletal injuries, neurological and cardiorespiratory conditions, post-surgical recovery, and pelvic health concerns, in people of every age.

Most people see meaningful change within six to ten sessions, no referral is needed in Ontario, and most extended health plans cover it. If you have been putting up with a nagging problem, or you are coming off surgery or an injury and want a plan built on measurements rather than guesswork, we would be glad to see you at KC Rehab here in Markham. You can book an assessment or call us at (905) 205-1668 whenever you are ready.
