Post-surgery physiotherapy

Chest physiotherapy after CABG or open-heart surgery

For patients and caregivers planning breathing care, early walking, and sternal precautions after coronary artery bypass grafting or other open-heart surgery — and understanding how this differs from cardiac rehabilitation.

Last reviewed: 25 July 2026 · Educational guide, not personal medical advice

Quick answer

After CABG or open-heart surgery through the breastbone, physiotherapy usually starts in hospital with deep breathing, supported coughing, and early mobilisation. Home visits can continue that practical work when you are stable — but they do not replace a comprehensive cardiac rehabilitation programme.

After CABG or sternotomy, physiotherapy usually starts in hospital with deep breathing, supported coughing, and early walking.
The breastbone commonly needs about 3 months to heal; heavy lifting is often restricted during that period.
Home physiotherapy can help with breathing practice, safe movement, and household function when you are medically stable.
A comprehensive cardiac rehabilitation programme is different from short-term chest physio — guidelines recommend cardiac rehab after revascularisation.
Follow your surgeon’s sternal and activity rules; do not copy a generic online programme.

Understanding CABG and open-heart recovery

Knowing what was operated on — and what still needs protection — makes physiotherapy goals clearer.

CABG creates new routes for blood to reach heart muscle using grafts from the chest, leg, or arm (NHS).
Open-heart surgery through a median sternotomy divides the breastbone so the surgeon can reach the heart; wires then hold the bone while it heals.
Pain, stiffness, shallow breathing, fatigue, and temporary breathlessness are common early on.
Donor-site wounds (leg or arm) can add walking or arm discomfort.
Protect the healing sternum from uneven strain, heavy loads, and activities your team has restricted.

What physiotherapy is intended to achieve

Goals should be functional and stage-specific — not slogans about perfect recovery.

Take deeper breaths and clear phlegm more comfortably
Sit out of bed, stand, and walk safely as soon as the team allows
Manage bed, chair, and bathroom transfers with less sternal strain
Move neck and shoulders enough to avoid avoidable stiffness
Practise stairs if needed before or after discharge
Teach caregivers how to help without pulling on your arms
Rebuild walking endurance toward daily independence
Recognise warning signs that need medical review

Typical rehabilitation phases

Timelines vary with the exact procedure, wound healing, complications, other health conditions, and your previous fitness. Use these stages as a map, not a guarantee.

1
Hospital — day 0 to early ward days
NHS guidance notes help from nurses and physiotherapists to get out of bed and move from the day after CABG. Typical early care includes deep breathing, supported cough or huff, sitting out, and short walks. Most people spend about a week in hospital, though timing varies.
2
Discharge and the first weeks at home
NHS advice: arrange help for the first days, care for wounds, take pain relief as needed, and start walking when you feel well enough. Light household tasks are usually more realistic than heavy chores. Exact lift and activity limits come from your discharge plan.
3
Early recovery (roughly the first 6 weeks)
NHS Inform and NHS England materials commonly describe returning to many normal activities around 6 weeks if recovery is straightforward — not a guarantee. Walking is the main exercise; build time and distance gradually without ending exhausted or unable to speak a sentence.
4
Sternal healing and cardiac rehabilitation
Guy’s and St Thomas’ and other NHS trusts often advise that the breastbone takes about 3 months to heal fully. NHS recovery pages commonly advise avoiding heavy lifting for 3 months. A comprehensive cardiac rehab programme — exercise, education, and risk-factor support — is usually offered in this phase and is not the same as short-term chest physiotherapy alone.

What happens during a physiotherapy session

A useful home session is an assessment and progress check — not only a massage or a printed sheet.

1
Review your discharge summary, wound advice, sternal or movement precautions, and any cardiac rehab referral
2
Ask about your priorities — breathlessness, sleep, stairs, bathroom transfers, return to work, or caregiver support
3
Screen chest pain pattern, breathlessness, wound concerns, calf symptoms, fever, dizziness, and oxygen needs within physiotherapy scope
4
Assess breathing pattern, cough effectiveness, posture, transfers, walking, balance, and shoulder comfort
5
Choose stage-appropriate breathing practice, mobilisation, and functional coaching — not a one-size sheet
6
Check walking-aid use if needed and teach safer sit-to-stand without pushing heavily through the arms
7
Teach a home programme caregivers can support, and explain when to stop
8
Record measurable progress and escalate cardiac, wound, or breathing concerns to your treating team

Practical preparation at home

Before the first home visit — or as soon as you return from hospital — small changes reduce fall risk and make breathing and walking practice safer.

Clear walking paths; remove loose rugs and trailing wires
Keep a firm chair with armrests, but practise rising without heavy arm-pushing if that is restricted
Place frequently used items within easy reach at waist height
Prepare a small pillow or folded towel for supported coughing
Keep discharge papers, medication list, and sternal precautions ready for the visit
Arrange caregiver help for the first days, especially for shopping, laundry, and pets that pull on a lead
Have prescribed respiratory equipment (for example an incentive spirometer) available only if your hospital issued one

Exercises and treatment techniques

The right techniques depend on your wound, pain control, secretions, oxygen needs, and surgical instructions. These are examples of what a clinician may use — not a do-it-yourself prescription.

Deep breathing practice

Purpose: Encourages fuller lung expansion when pain and reduced mobility make breathing shallow, which can raise chest-infection risk after heart surgery (Guy’s and St Thomas’, South Tees NHS).
When it may be used: Often taught before surgery and restarted from the first postoperative day if your team approves.
Stop and get advice if: Stop and seek advice if you feel dizzy, develop new severe chest pain, or become markedly more breathless than your usual recovery pattern.

Supported huff and cough

Purpose: Helps clear phlegm while reducing discomfort at the wound. A pillow or towel held against the chest supports the incision during coughing.
When it may be used: Used when secretions are present, or as taught for early postoperative chest care.
Stop and get advice if: Seek urgent review for coughing up blood, sudden severe breathlessness, or wound opening during coughing.

Early mobilisation and graded walking

Purpose: Supports lung expansion, circulation, strength, and confidence. Walking is the main everyday exercise recommended by many NHS cardiac surgery teams.
When it may be used: Usually from the day after surgery in hospital, then progressed at home from the distance you managed on the ward.
Stop and get advice if: Stop for angina-type pain, nausea, dizziness, marked breathlessness, or becoming cold and clammy — seek medical help if this happens (Kent Community Health NHS).

Shoulder and posture mobility (within protocol)

Purpose: Reduces avoidable neck, back, and shoulder stiffness after sternotomy positioning and bed rest.
When it may be used: Many trusts encourage gentle neck and shoulder movement early; some use ‘Keep Your Move in the Tube’ load guidance rather than total arm rest.
Stop and get advice if: Do not force painful end-range reaching or lifting. Report worsening sternal clicking, instability, or wound pain to your surgical team.

Incentive spirometry (only if prescribed)

Purpose: Some hospitals issue a device to cue deep breaths. Cochrane reviews have not shown clear benefit of incentive spirometry over other physiotherapy approaches after CABG, so it is not essential for every patient.
When it may be used: Use only as taught by your hospital team — not as a substitute for walking and supported coughing.
Stop and get advice if: Stop if dizzy or in significant pain. Ask your clinician before buying a device yourself.

Red flags — seek medical help

Stop physiotherapy and get medical help for the following. These signs are highlighted across NHS cardiac-surgery patient guidance.

Emergency care now

Sudden severe chest pain, pressure, or pain spreading to the jaw, arm, or back — treat as a medical emergency
Severe or rapidly worsening breathlessness, fainting, collapse, confusion, or cold clammy skin
Coughing up blood, or sudden inability to catch your breath

Contact your cardiac surgeon, hospital team, or urgent medical care promptly

Worsening sternal clicking, a feeling that the breastbone is moving, or rapidly increasing wound pain
Wound redness, pus, opening, unexpected bleeding, or fever / feeling hot and shivery
New calf pain, swelling, redness, or tenderness — possible clot risk
Angina-like symptoms returning during usual light activity
Fall onto the chest or a new injury to the operated area
Oxygen saturation falling below the target your discharge team set, if you monitor at home

A physiotherapist can help you notice warning signs, but they do not replace emergency, cardiology, or surgical assessment when these symptoms appear.

Home chest physiotherapy vs cardiac rehabilitation

Patients often search for ‘chest physio at home’ when what they also need is a longer cardiac rehabilitation pathway. Both can matter — for different jobs.

Short-term chest physiotherapy focuses on

Deep breathing and secretion clearance
Early walking and safe transfers
Sternal-precaution coaching
Shoulder comfort and fall-risk reduction at home

Comprehensive cardiac rehab usually includes

Structured exercise progression
Heart-disease education and medicines advice
Lifestyle and risk-factor support
Stress management and longer-term secondary prevention

When home physiotherapy may be useful

Home physiotherapy can be practical after CABG or open-heart surgery when you are medically stable enough for community care — it is not always better than clinic or hospital rehab.

Home visits can help when

Less exhausting travel while stamina and sternal comfort are still limited
Assessment of your real bed, chair, bathroom, stairs, and walking routes
Breathing and mobility practice adapted to your home layout
Caregivers can watch sessions and learn safer assistance
Help bridging the gap between hospital discharge and starting cardiac rehab

Prefer clinic or hospital when

You still need close medical monitoring or are medically unstable
You need a supervised cardiac rehabilitation exercise class or monitored programme
Specialised equipment or multi-disciplinary rehab is required
Urgent investigation of wound, heart, or breathing symptoms is needed
More hands-on assistance is required than your household can provide safely
Your surgeon or cardiologist advises centre-based rehab rather than home sessions alone

Why qualifications and verification matter

Rehabilitation after heart surgery is more than massage or a shared breathing PDF. An unqualified or unverified provider may ignore sternal precautions, progress exercise too quickly, miss wound or clot warning signs, or treat short-term chest physio as a full substitute for cardiac rehabilitation.

Before you book, check that the physiotherapist has:

Recognised physiotherapy qualifications
Identity and professional details you can verify
Experience with cardiac surgery, CABG, or sternotomy rehabilitation
Willingness to review your discharge summary and sternal precautions
A clear plan for breathing work, walking progression, red flags, and when to stop
Willingness to support — not replace — your cardiac rehab and surgical follow-up

Questions to ask a physiotherapist

Use these in your first call or visit — caregivers can screenshot this list.

Have you treated patients after CABG or open-heart surgery via sternotomy before?
Will you review my discharge summary and sternal precautions before starting?
What should therapy aim to achieve at my current stage — breathing, walking, or both?
How will you measure improvement — walking distance, stairs, cough comfort, or something else?
Which symptoms would make you stop a session and contact my cardiac team?
How should my caregiver help me get out of bed or a chair without straining my chest?
Do you recommend continuing towards a formal cardiac rehabilitation programme?
When would you recommend clinic-based or specialist cardiac rehab instead of home visits alone?

Frequently asked questions

+When should physiotherapy begin after CABG or open-heart surgery?

In hospital pathways described by NHS services, nurses and physiotherapists usually help you get out of bed and move from the day after the operation. Breathing exercises are often taught before surgery and restarted early afterwards. After discharge, continue the plan you were given and arrange further physiotherapy if breathlessness, mobility, stairs, or caregiver support still need supervised help.

+Is chest physiotherapy the same as cardiac rehabilitation?

No. Early chest physiotherapy focuses on breathing, secretion clearance, safe mobility, and sternal-precaution coaching. Cardiac rehabilitation is a broader programme with structured exercise, education, and secondary prevention. The 2021 ACC/AHA/SCAI revascularisation guideline gives a Class I recommendation that patients who have undergone revascularisation should be prescribed a comprehensive cardiac rehabilitation programme (home-based or centre-based).

+How long do sternal precautions last?

Many NHS trusts advise that the breastbone takes about 3 months to heal. NHS CABG recovery advice commonly includes avoiding heavy lifting for 3 months. Exact rules — including whether your centre uses traditional weight limits or ‘Keep Your Move in the Tube’ guidance — come from your surgeon and physiotherapist. Protocols are not identical everywhere.

+Will physiotherapy be painful?

Some wound discomfort with deep breathing, coughing, and walking is common. Good pain control is part of effective chest care. That is different from sudden severe chest pain, rapidly worsening sternal pain, or symptoms that feel like angina. A careful physiotherapist grades effort and stops for warning signs.

+Can rehabilitation be completed entirely at home?

Parts of early recovery — walking practice, breathing exercises, and functional coaching — can continue at home if you are medically stable. Cochrane evidence suggests home-based and centre-based cardiac rehabilitation can be similarly effective for key outcomes in eligible patients, but that does not mean every unsupervised home routine equals a full rehab programme. Many people use a mix: home support early, then a structured cardiac rehab pathway.

+Do I need an incentive spirometer?

Only if your hospital team issued one and taught you how to use it. A Cochrane review found no clear evidence that incentive spirometry is better than other physiotherapy approaches for preventing lung complications after CABG. Walking, deep breathing, and supported coughing remain the core practical tools in many NHS leaflets.

+How can I tell if I am progressing too quickly?

Warning signs include ending walks exhausted, being too breathless to speak a sentence, new or worsening angina-type pain, increasing sternal clicking or wound strain, or needing much more pain medicine just to complete usual activity. Slow down and check with your physiotherapist or cardiac team.

+When might home physiotherapy not be appropriate?

Home visits are a poor fit if you are medically unstable, need urgent investigation, require monitored cardiac rehab exercise that cannot be delivered safely at home, or need more assistance than your household can provide. In those situations, hospital, clinic, or a specialist cardiac rehabilitation service is more appropriate.
