Physiotherapy deals with restoring, maintaining and improving physical movement, function and overall wellbeing through exercise and hands-on care rather than through surgery or medication. In practice that covers five broad groups of conditions: musculoskeletal problems, neurological conditions, cardiorespiratory issues, post-surgical recovery, and pelvic health.

That range surprises most people, who assume physiotherapy is only for back pain and sports injuries. Below we go through each group, the conditions inside it, what treatment actually targets in each case, the less obvious problems physiotherapy handles, and where the edges of its scope genuinely are.

What Does Physiotherapy Deal With?

Physiotherapy deals with any condition that limits how well a person moves or functions, across five main groups: musculoskeletal, neurological, cardiorespiratory, post-surgical, and pelvic health. Health conditions in all five groups share one feature, which is that they reduce a person’s physical capacity to do ordinary things.

• Musculoskeletal problems: back and neck pain, arthritis, joint problems, tendon injuries, sprains, strains and sports injuries
• Neurological conditions: recovery after stroke, Parkinson’s disease, multiple sclerosis, and brain or spinal trauma
• Cardiorespiratory issues: asthma, recovery after a heart attack, and managing chronic obstructive pulmonary disease (COPD)
• Post-surgical rehabilitation: recovery after joint replacements, ligament reconstruction, rotator cuff repair, spinal surgery and fracture fixation
• Pelvic health: bladder and bowel problems, including those related to pregnancy and childbirth

Childbirth-related problems sit at one end of that list and stroke recovery at the other, which is exactly why the scope looks scattered until you see what connects it. Our physiotherapy caseload reflects the same spread, weighted heavily toward the first group.

What Body Systems Does Physiotherapy Work On?

Physiotherapy works on four body systems: the musculoskeletal system, the nervous system, the cardiopulmonary system, and the integumentary system, meaning skin and the sensory feedback it provides. Feedback from skin and nerves matters more than people expect, because balance and coordination depend on the body knowing where it is in space.

Space and position awareness sits in the nervous system, strength sits in the muscles and bones, endurance sits in the heart and lungs, and all three have to cooperate for a person to walk across a room. Treating one in isolation rarely produces a lasting result.

Why So Many Different Conditions Fall Under One Profession

All of these conditions fall under one profession because they share a single consequence: each one reduces a person’s ability to move and function. Function is the common thread, not the diagnosis. A stroke, a torn meniscus and severe COPD have nothing in common medically, yet all three leave someone unable to do things they could do before.

Doing things again is the target in every case, and the tools are the same each time: assessment of how the person currently moves, graded exercise to rebuild capacity, hands-on work to restore joint and tissue mobility, and education so the person can manage their own condition.

Managing your own condition is why the need is so large. The World Health Organization, with the Institute for Health Metrics and Evaluation in The Lancet, estimated that 2.41 billion people worldwide live with a condition that would benefit from rehabilitation, a figure up 63 per cent since 1990 and amounting to roughly one in three people.

What Musculoskeletal Conditions Does Physiotherapy Treat?

Physiotherapy treats musculoskeletal conditions affecting bones, joints, muscles, ligaments and tendons, including low back pain, neck pain, arthritis, frozen shoulder, tennis and golfer’s elbow, plantar fasciitis, sciatica, herniated discs, sprains and strains. Strains and sprains are the everyday end of the group, while arthritis and disc problems sit at the long-term end.

Long-term musculoskeletal problems dominate the global burden. WHO data shows approximately 1.71 billion people live with musculoskeletal conditions, and low back pain is the single leading cause of disability in 160 countries, affecting roughly 590 million people.

Affecting that many people means this is where most physiotherapy happens, and where the evidence base is strongest. Where a recurring problem traces back to how the foot strikes the ground, custom orthotics address the mechanics feeding the symptom.

What Is the Most Common Reason People Need Physiotherapy?

The most common reason people need physiotherapy is musculoskeletal pain, with low back pain leading the category by a wide margin. A wide margin is not an exaggeration: musculoskeletal conditions make up the large majority of outpatient physiotherapy caseloads, and back pain alone accounts for a substantial share of those.

The share is so high because these conditions respond to exactly what physiotherapy provides. Load, movement and strength are the three levers that change musculoskeletal problems, and they are the three levers a physiotherapist pulls.

How Does Physiotherapy Treat Back Pain?

Physiotherapy treats back pain by rebuilding the strength and load tolerance of the muscles supporting the spine, restoring movement in stiff segments, and correcting the movement patterns that keep irritating the area. Irritating movement patterns are usually the reason the pain keeps returning after it settles.

Settling pain and preventing its return are different jobs, and the research measures both. Cochrane’s review of exercise therapy for chronic low back pain, covering 249 trials and 24,486 participants, found pain improved by a pooled mean of 7.3 points out of 100 compared with no treatment, usual care or placebo. Structured exercise rehabilitation is how that improvement is delivered in practice.

What Neurological Conditions Does Physiotherapy Treat?

Physiotherapy treats neurological conditions including loss of mobility after stroke, Parkinson’s disease, multiple sclerosis, and movement problems following brain or spinal cord trauma. Trauma and progressive disease need different approaches, but both target the same outcomes: balance, coordination, gait and independence.

Independence depends heavily on not falling, which is where the evidence is strongest. Cochrane’s review of 108 trials with 23,407 participants found exercise reduces the rate of falls by 23 per cent, with balance and functional training alone reducing it by 24 per cent, and the effect was larger in trials where a health professional, usually a physiotherapist, delivered the programme.

Delivering these programmes involves retraining the nervous system rather than simply strengthening muscles. The brain has to relearn patterns it has lost, which is why neurological rehabilitation typically runs longer than musculoskeletal work.

Does Physiotherapy Treat Dizziness or Vertigo?

Yes, physiotherapy treats dizziness and vertigo through vestibular rehabilitation, which retrains the balance system in the inner ear and its coordination with vision and body position. Position and vision have to agree with what the inner ear reports, and dizziness often comes from those three signals conflicting. Treatment involves specific head and eye movement exercises, balance retraining, and in some cases repositioning manoeuvres.

Manoeuvres of that kind are among the fastest-acting treatments in the field, resolving some types of vertigo in a small number of sessions. Most people have no idea physiotherapy handles this at all.

What Cardiorespiratory and Post-Surgical Work Does Physiotherapy Cover?

Physiotherapy covers cardiorespiratory conditions including recovery after a heart attack, breathing difficulty from asthma and COPD, and post-surgical recovery from joint replacements, ligament reconstruction and spinal surgery. Spinal and joint surgery recovery makes up a large share of clinic caseloads, while cardiorespiratory work happens more often in hospital and community programmes.

Programmes in both areas target endurance and efficiency rather than just strength. Breathing technique, airway clearance and graded activity tolerance are the tools on the respiratory side, while range of motion, progressive loading and functional retraining drive post-surgical recovery.

Driving recovery after surgery has strong trial support, and in some cases physiotherapy performs as well as the operation itself. A multicentre randomized trial published in the New England Journal of Medicine, covering 351 patients with a degenerative meniscal tear and mild-to-moderate knee osteoarthritis, found no significant difference in function or pain at 6 and 12 months between surgery with post-operative physiotherapy and physiotherapy alone, and the ESCAPE trial published in JAMA found physiotherapy noninferior to arthroscopic partial meniscectomy over 24 months across 321 patients. Cochrane’s knee osteoarthritis review of 44 trials found pain improved 12 points out of 100 and function 10 points out of 100 with exercise. The table below sets out what each of the five groups involves.

Condition Group	Example Conditions	What Treatment Targets	Typical Methods	Typical Timeframe
Musculoskeletal	Back and neck pain, arthritis, tendon injuries, sprains	Load tolerance, joint mobility, strength	Therapeutic exercise, manual therapy, education	6 to 12 weeks
Neurological	Stroke, Parkinson’s, MS, spinal cord injury	Balance, coordination, gait, independence	Balance and functional training, gait retraining	Months, often ongoing
Cardiorespiratory	Post-cardiac event, asthma, COPD	Endurance, breathing efficiency, activity tolerance	Graded exercise, breathing technique, airway clearance	8 to 12 weeks, then maintenance
Post-surgical	Joint replacement, ACL reconstruction, rotator cuff repair	Range of motion, strength, return to function	Protocol-guided exercise, manual therapy, modalities	3 to 6 months
Pelvic health	Incontinence, postpartum recovery, pelvic pain	Pelvic floor strength, coordination, bladder control	Targeted strengthening, coordination retraining, education	8 to 16 weeks

Modalities support the exercise work in several of these groups rather than replacing it, and where swelling and slow tissue healing are holding recovery back, laser therapy is used alongside hands-on treatment.

What Pelvic Health Conditions Does Physiotherapy Deal With?

Physiotherapy deals with pelvic health conditions including urinary and bowel incontinence, pelvic organ prolapse, pelvic pain, and the pregnancy and postpartum problems that come with them. Problems of this kind are extremely common and widely assumed to be permanent, which is why so many people never mention them to anyone.

Mentioning them is the only barrier in most cases. The pelvic floor is a muscle group, and it responds to assessment, graded strengthening and coordination retraining the same way any other muscle group does, which is what pelvic floor therapy provides.

What Surprising Problems Does Physiotherapy Deal With?

Physiotherapy deals with several problems most people never associate with it, including jaw pain, dizziness, concussion symptoms, cancer-related fatigue and deconditioning, and persistent chronic pain. Chronic pain in particular sits squarely in physiotherapy’s scope, because it involves movement avoidance, deconditioning and nervous system sensitivity rather than ongoing tissue damage alone.

Tissue sensitivity of that kind responds to graded exposure, pacing and education rather than rest. Where muscle guarding and persistent tension are part of the picture, medical acupuncture is one of the tools used alongside the movement work.

Alongside the obvious conditions, the general rule is worth knowing: if a problem limits how you move or how much you can physically do, it is worth asking whether physiotherapy can help. The answer is yes more often than people expect.

Can Physiotherapy Help Jaw Pain?

Yes, physiotherapy helps jaw pain by treating the temporomandibular joint and the muscles controlling it, alongside the neck and postural factors that frequently contribute. Contributing factors matter here because jaw pain is rarely isolated to the jaw. Treatment typically combines manual therapy to the joint and surrounding muscles, specific jaw exercises, and changes to habits such as clenching and posture.

Does Physiotherapy Deal With Accident and Workplace Injuries?

Yes, physiotherapy deals with motor vehicle accident injuries and workplace injuries, and both have established treatment and funding pathways in Ontario. Ontario handles these through motor vehicle accident insurance and workplace injury claims, which means treatment is often covered rather than paid out of pocket.

Out-of-pocket cost stops many people seeking treatment after an accident, which is unfortunate given how much difference early rehabilitation makes. Whiplash, soft tissue injuries, repetitive strain and postural dysfunction from desk work all respond well, and physiotherapy treatment in Markham handles these cases regularly.

Does Physiotherapy Help After a Car Accident?

Yes, physiotherapy helps after a car accident by treating whiplash, soft tissue injuries, joint stiffness and the movement guarding that develops afterwards. Guarding develops quickly after a collision as the body protects an irritated area, and left alone it can persist long after the original tissue has healed. Early assessment matters, both clinically and for documenting the injury properly for an insurance claim.

What Does a Physiotherapist Actually Do About These Conditions?

A physiotherapist assesses how you move, identifies what is limiting you, builds a treatment plan against measurable goals, delivers hands-on and exercise-based treatment, and teaches you to manage the problem yourself. Managing it yourself is the endpoint in every one of the five condition groups, whatever the diagnosis.

1. Assessment. A detailed history plus testing of range of motion, strength, balance and function to find out what is actually limiting you
2. Diagnosis and planning. Identifying the movement problem behind the symptom and setting measurable goals with you
3. Hands-on treatment. Manual therapy, joint mobilization and soft tissue work to restore mobility and reduce pain
4. Exercise prescription. Graded loading to rebuild the strength and capacity the condition took away
5. Education. Explaining the condition, how to load it safely, and what to do during a flare-up
6. Reassessment. Measuring progress at intervals and adjusting the plan as you change

Changing the plan as you progress is what separates a treatment course from a set of exercises. Soft tissue work is often shared across disciplines too, and massage therapy runs alongside physiotherapy for many patients.

Who Can Physiotherapy Help?

Physiotherapy helps people of all ages, from infants with developmental movement problems through to older adults managing arthritis and fall risk. Fall risk and arthritis dominate the older end, while sports injuries and post-surgical recovery fill the middle, and developmental and paediatric work covers the youngest patients.

Patients in Ontario can also book directly. The College of Physiotherapists of Ontario classifies physiotherapists as primary care practitioners, so no referral is needed, and our physiotherapists in Markham see patients who come straight from a family doctor and patients who simply booked online.

Booking online has become the norm as the profession has moved into community practice. The Canadian Institute for Health Information reported that in 2023, 69.9 per cent of physiotherapists in Canada worked primarily in community settings rather than hospitals, and our broader rehabilitation services follow that same clinic-based model.

When Physiotherapy Is Not the Right Answer

Physiotherapy is not the right answer when symptoms point to a medical problem needing investigation, when a condition requires surgery or medication first, or when another discipline is better suited to the problem. Problems needing urgent medical attention include unexplained weight loss, night pain unchanged by position, fever alongside back pain, progressive weakness, saddle numbness, and loss of bladder or bowel control.

Bladder and bowel changes combined with sudden weakness need same-day medical care rather than a physiotherapy appointment, which is why screening for signs like these is part of every initial physiotherapy assessment. Finding none means movement-based treatment is appropriate, and finding one means a prompt referral elsewhere.

Referring elsewhere sometimes means to another discipline rather than to a doctor. Spinal joint mechanics often respond particularly well to chiropractic care, and the most efficient plan for some patients runs both disciplines together rather than choosing between them.

What Happens If Physiotherapy Doesn’t Work?

If physiotherapy is not working after a reasonable course of treatment, the plan should be reassessed rather than simply continued. Continuing an unproductive plan wastes time that a fresh assessment would recover. Most commonly the issue is an inaccurate working diagnosis, insufficient loading, or poor adherence to the home programme, and all three are fixable.

Fixing them starts with a conversation. Where reassessment does not explain the lack of progress, the next step is referral back to a physician for imaging or further investigation.

Frequently Asked Questions

What Is Better, a Chiropractor or a Physiotherapist?

Neither is better in general, and the right choice depends on the problem. Physiotherapy suits broad rehabilitation, post-surgical recovery, neurological conditions, and anything needing progressive strengthening. Chiropractic focuses more closely on spinal and joint mechanics using adjustment and manual techniques. Both are regulated primary care professions, and many patients do best with both working from one coordinated plan.

What Is the Difference Between Physiotherapy and Massage Therapy?

Physiotherapy assesses and treats movement problems using exercise, manual therapy and education, while massage therapy focuses on soft tissue treatment to reduce muscle tension and improve circulation. Circulation and tension work supports rehabilitation well but does not rebuild strength or capacity, which is why the two are commonly used together rather than as alternatives.

What Are the Side Effects of Physiotherapy?

The usual side effects of physiotherapy are temporary muscle soreness and tiredness after a session, both of which reflect tissue adaptation rather than harm. Cochrane’s chronic low back pain review noted that reported side effects of exercise therapy were minor and occurred at similar rates in comparison groups doing no exercise at all. Tell your physiotherapist if anything feels excessive so the dosage can be adjusted.

How Long Do You Need Physio For?

Most people need physiotherapy for six to twelve weeks, though the answer varies by condition group. Musculoskeletal problems generally resolve fastest, post-surgical recovery runs three to six months, and neurological conditions often involve longer or ongoing care. Your physiotherapist should give you an estimate after the initial assessment and revise it as you progress.

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 here are primary care practitioners and patients can book directly. Some extended health plans still require a referral before they will reimburse treatment, so it is worth checking your policy wording before your first visit.

Does Physiotherapy Treat Children?

Yes, physiotherapy treats children through paediatric physiotherapy, which addresses developmental movement delays, congenital conditions, sports injuries in young athletes, and recovery from childhood injuries or surgery. Treatment for children is built around play and age-appropriate activity rather than adult-style exercise programmes, and it usually involves parents directly in the home programme.

The Bottom Line

Physiotherapy deals with five broad groups of conditions: musculoskeletal problems, neurological conditions, cardiorespiratory issues, post-surgical recovery and pelvic health, plus a set of less obvious problems including jaw pain, vertigo, concussion symptoms and persistent chronic pain. What ties them together is not the diagnosis but the consequence, since every one of them reduces how well a person moves and functions, and movement and function are what physiotherapy restores.

The practical takeaway is simple enough: if something is limiting what you can physically do, it is worth asking whether physiotherapy can help, because the answer is yes more often than most people assume. If you are dealing with pain, stiffness or a recovery that has stalled in Markham, the team at KC Rehab can assess what is going on and tell you honestly whether we are the right starting point, and you are welcome to contact us with any questions.
