Facial Palsy Physiotherapy: Exercises and Rehabilitation

First, medical assessment

Sudden facial weakness must be assessed by a doctor straight away to rule out stroke and other causes. Bell's palsy is diagnosed once other causes are excluded. Early medical treatment, often steroids, may improve outcomes and is time-sensitive.

How recovery usually goes

Many people with Bell's palsy start to recover within a few weeks, and most recover well over several months. Some recover only partially, and a smaller number develop problems such as synkinesis, where moving one part of the face causes unwanted movement elsewhere, like the eye closing when smiling.

Eye care comes first

When the eye can't close fully, it's at risk of drying and damage. Eye drops, ointment and taping the eye closed at night may be advised by the doctor. Protecting the eye is a priority.

Physiotherapy in early recovery

Early on, when movement is minimal, treatment focuses on:

• gentle facial massage to maintain circulation and comfort
• awareness and gentle, small, controlled movements in front of a mirror
• advice on eating, drinking and eye care

Strong, forceful exercises and electrical stimulation are generally avoided in Bell's palsy because they may encourage unwanted movement patterns.

As movement returns

Exercises become more specific: small, slow, symmetrical movements such as raising the eyebrows, gently closing the eyes, smiling and pursing the lips, practised with a mirror. The focus is precision and symmetry rather than strength.

Managing synkinesis

If synkinesis develops, specialised techniques help separate movements and reduce tightness. This needs a physiotherapist experienced in facial rehabilitation.

Why gentle beats forceful

It's tempting to think that harder exercise gives faster results. With facial nerve recovery, that thinking can backfire. As the nerve regrows, fibres can reconnect to the wrong muscles. Forceful, repeated grimacing during this phase may encourage those mixed signals and make synkinesis more likely.

So facial exercises are small, slow and precise, done in front of a mirror, with the aim of making both sides move the same amount. If the good side is overpowering the weak side, the instruction is often to move less on the good side, not more on the weak side. That keeps the face balanced and avoids pulling it towards the stronger side.

Chewing gum and blowing balloons, often suggested by well-meaning relatives, tend to use the face in strong, unbalanced ways. They're not usually part of a physiotherapy plan in early recovery.

Emotional impact deserves mention too. A changed face affects confidence, eating in public and photographs. That's a real part of recovery, and it's reasonable to ask for support with it.

Timeline

Recovery varies. Many improve over three to six months. Recovery can continue for a year or more in some cases.
