Bell's palsy: the role of specialised physiotherapy in restoring facial function

Bell's palsy is a peripheral neurological condition that affects the facial nerve, causing weakness or paralysis of the muscles on one side of the face. Beyond the obvious physical impact, it can significantly interfere with emotional well-being and activities such as speaking, chewing, blinking, and expressing emotions.

In this article, we discuss the relevance of Physiotherapy after a diagnosis of Bell's Palsy, with particular emphasis on the importance of a specialist clinical evaluation and an approach targeted at facial paralysis.

The importance of physiotherapy in Bell's palsy

Although often transient, Bell's Palsy can be an emotionally demanding experience, with significant functional repercussions. In this context, Physiotherapy plays a central role in supporting neuromuscular recovery, contributing to the reorganisation of facial movement and the improvement of quality of life.

Early, targeted intervention allows for work not only on muscle activation but also on fine motor control, coordination between muscle groups, and facial relaxation capacity, all of which are fundamental aspects for a balanced recovery.

Possible complications and the preventive role of Physiotherapy

Changes in facial mobility can lead to secondary changes, such as muscle contractures, muscle fibre atrophy, and compensatory movement patterns.

Physiotherapy acts preventatively through specific techniques aimed at optimising muscular functionality and promoting freer, more organised facial movements, which are essential for actions such as smiling, closing the eyes, or frowning.

This specialised treatment also helps to reduce stiffness in specific areas of the face and the excessive strain on certain muscles, something common when the body tries to compensate for difficulty in moving the face.

Facial exercises: what to avoid during recovery

The recovery of facial movements is not just about the regeneration of the facial nerve. It is essential to maintain adequate relaxation of the face to favour correct contraction of the facial muscles.

Exercising without the supervision or recommendation of a physiotherapist specialising in facial paralysis may not be the most appropriate approach to this process. Contrary to what you may have read or heard, it is not advisable to chew gum, blow up balloons or make faces to strengthen the facial muscles.

This type of exercise offers no benefits and can result in inadequate reinnervation of the facial nerve, as well as excessive recruitment of the facial muscles. This can lead to abnormal movement patterns, including mass movements, increased tension in specific areas of the face, and the development of synkinesis.

Synkinesias are involuntary muscular movements that occur during the execution of a voluntary movement, such as closing your eyes and simultaneously raising the corner of your mouth.

When to start specialist physiotherapy for Bell's Palsy

Physiotherapy should be started as early as possible. The first few days are crucial for correct guidance on what you should and should not do, for understanding what is happening with your face and learning to work with its potential, allowing for greater freedom of movement.

Supervised exercises by specialist physiotherapists help to maintain flexibility, prevent muscle contractures and minimise abnormal movement patterns. Furthermore, specialist physiotherapy for facial palsy contributes to improved muscle coordination and helps to prevent the formation of synkinesis, facilitating the harmonious reintegration of facial movements.

Early initiation of physiotherapy is associated with a more favourable clinical evolution and a more appropriate reorganisation of facial movement.

Specialised physiotherapy in Portugal: new avenues in facial rehabilitation

In Portugal, physiotherapy specialised in the recovery of facial paralysis is still in its early stages. The physiology and biomechanics of the face and facial expressions are different and require specific care.

Resources such as the use of ice, stimulation and rapid movements, electro-stimulation, facial mimicry exercises in front of the mirror and homework such as chewing gum or inflating balloons are not currently considered to be the most suitable for recovery from facial paralysis, according to current scientific knowledge.

Are you recovering from facial paralysis and have been doing some of these exercises, how does your face feel afterwards? Lighter or tenser?

The use of these resources is primarily based on excessive muscle strength gain, without adequately considering the facial nerve's capacity to generate movement, nor the importance of relaxation and control of facial movements. This can promote compensatory movements and the onset of sequelae such as contractures and synkinesias.

The most recent approach to Bell's palsy favours different strategies, and it is advisable to review these types of exercises to avoid an unnecessary increase in muscle tension. A specialist assessment allows for an understanding of which techniques are most suitable for each case and supports a more organised recovery.

Specialised physiotherapy to support functional recovery

The recovery from Bell's palsy can be a demanding journey, but a specialised physiotherapy approach can significantly contribute to reducing sequelae and reorganising facial movement patterns.

A detailed clinical assessment allows for the identification of asymmetries, compensatory patterns, and specific limitations, serving as the basis for an individualised plan, tailored to each person's recovery pace.

Understanding Bell's Palsy from an integrative perspective

Facial function recovery involves multiple dimensions: neurological, muscular, functional, and emotional. An integrative approach acknowledges this complexity and values interventions that promote body awareness, motor coordination, and global well-being.

Seeking support from professionals with specific training in facial palsy can help you better understand what is happening with your face and what the most suitable strategies are for this process, contributing to a more informed and balanced experience of recovery.
