When chest physiotherapy genuinely has a role

Chest physiotherapy has a clear place in managing particular conditions: a child with thick secretions they cannot clear and an ineffective cough, a child with respiratory muscle weakness from a neuromuscular condition, some chronic lung diseases, and situations where part of a lung has collapsed. In these cases the techniques help move secretions towards the larger airways so they can be cleared.

What matters is the indication, not the symptom. "The child has a cough" is not an indication. What decides it is what we find on examination: breath sounds, breathing pattern, the effectiveness of the cough, and the child's medical history. That is why a session always begins with an assessment, and sometimes ends with us sending you home without any treatment at all.

And when the research says it should not be used

We choose to say this plainly. For acute bronchiolitis — the small-airway infection that is extremely common in babies under two, usually starting as a cold and turning into noisy breathing — a Cochrane review concludes that chest physiotherapy provides no benefit.

Conventional and forced expiratory techniques were not shown to reduce the severity of the illness, improve respiratory parameters, shorten hospital stay, or reduce oxygen requirements. For slow passive expiratory techniques the same review reports a possible improvement in disease severity in infants with moderately severe bronchiolitis — on low-certainty evidence, so not a basis for making it routine. For forced expiratory techniques in infants with severe bronchiolitis, high-certainty evidence shows that they are not merely of no benefit but can cause severe adverse effects. Current practice guidelines therefore recommend against routine use.

What that means for you: if your child arrives with acute bronchiolitis, we will not perform chest physiotherapy on them. We will assess their breathing, show you the signs to watch for at home, help with comfort and hydration, and point you to a doctor — because that is the right answer.

What we do for an ordinary cough and cold

Most childhood coughs and colds get better on their own, and what genuinely helps is simple. We help you do those things properly: sleeping and carrying a little more upright, clearing the nose with saline and a safe aspirator, keeping fluids up, and recognizing when a child's cough is already doing its job and should be left alone.

The infrared (IRR) we offer works as gentle warmth over the chest or back. Its effect is comfort — warm, relaxed, a calmer child — and not treatment of an infection. We use it at a measured distance and for a measured time, never on broken skin, never on a baby who cannot tell us it feels too hot, and never unattended.

A light relaxation massage often closes the session. The honest reason: an uncomfortable child settles, and a worried parent has something they can do. That is useful. It is not medicine.

Frequently asked questions

My child has a chesty cough. Shouldn't the phlegm be patted out?

Not in every child. Tapping the chest (percussion) is a technique with specific indications, and in ordinary respiratory infections and acute bronchiolitis the research shows no benefit. A healthy child with a strong cough already has a clearance mechanism far more effective than anyone's hands. We check whether the cough is effective before deciding anything.

Then why is this service still offered?

Because some children genuinely need it — children with neuromuscular conditions, chronic lung disease, or an ineffective cough — and for them the techniques matter. What we avoid is giving it to every child who coughs. The assessment at the start of the session exists precisely to tell the two apart.

Is infrared safe for a baby?

At the right distance and duration, and with supervision, infrared is gentle surface warming. The risk is overheating, and that risk is greatest in exactly the children who cannot say they are too hot. So we never leave a child alone under the lamp, never use it on broken or sunburnt skin, and stop as soon as the skin reddens or goes beyond pleasantly warm.
