Physical Therapy for Bell's Palsy: Techniques and Exercises


Bells Palsy

Bell's Palsy, a sudden and temporary facial paralysis, can swiftly disrupt daily life. Its characteristic facial asymmetry, distorted expressions, and compromised eye closure hinder functionality and impact emotional well-being.


While the origins of this condition can be complex and elusive, the journey to recovery can be aided by the gentle guidance of physical therapy for Bell's Palsy.


What Is Bell's Palsy?


Bell's Palsy is a medical condition best characterized by sudden, temporary weakness or paralysis of the muscles on one side of the face. This condition occurs due to the inflammation or damage of the facial nerve, also known as the seventh cranial nerve.


The exact cause of Bell's Palsy is not always clear, but it is often thought to be related to viral infections, particularly herpes simplex virus (HSV), which can lead to inflammation of the facial nerve.


The symptoms of Bell's Palsy can appear suddenly and usually peak within 48 hours. One of the ways to treat and ease the symptoms of the condition is physical therapy for Bell's Palsy.


Signs and Symptoms of Bell's Palsy


The most noticeable and characteristic symptom of Bell's Palsy is the abrupt onset of facial asymmetry. The affected side of the face may droop, resulting in a lopsided appearance. This facial weakness can lead to difficulty performing everyday tasks such as smiling, blinking, or even closing the eye.


Additionally, the mouth may become distorted, causing challenges in speaking, eating, and maintaining oral hygiene. The eyebrow on the affected side may also have difficulty raising, further contributing to the overall asymmetry.


Another crucial symptom is the inability to fully close the eye on the affected side. This can lead to dryness, irritation, and potential damage to the cornea due to inadequate lubrication, which underscores the necessity of lubricating eye drops or ointments.

Signs and Symptoms of Bell's Palsy

Bell's Palsy might also influence the sense of taste, causing a diminished or altered perception of taste on the front two-thirds of the tongue.


Furthermore, some people with Bell's palsy experience hyperacusis, a heightened sensitivity to sound in one ear.


Common signs and symptoms include:


  • Sudden weakness or paralysis on one side of the face making it difficult to smile, close the eye, or raise the eyebrow on that side.

  • Drooping of the mouth or eyelid on one side.

  • Difficulty in closing one eye, leading to dryness and irritation.

  • Loss of the sense of taste on the front two-thirds of the tongue.

  • Increased sensitivity to sound in one ear (hyperacusis).


Physical therapy for Bell's Palsy may help manage all these symptoms.


What Causes Bell's Palsy?


Bell's Palsy is generally believed to be caused by inflammation or compression of the facial nerve. The exact cause of this inflammation or compression is not always clear, but it is often associated with viral infections, particularly the herpes simplex virus (HSV).


  • Viral Infections: Viral infections, especially those caused by the herpes simplex virus (HSV), are commonly linked to Bell's Palsy. HSV can cause facial nerve inflammation, leading to the characteristic symptoms of facial weakness or paralysis.

  • Immune System Response: Inflammation of the facial nerve might be triggered by an abnormal immune system response. The body's immune reaction to a viral infection could result in inflammation around the nerve, causing its dysfunction.

  • Hereditary Factors: Some genetic predispositions might make certain individuals more susceptible to developing Bell's Palsy.

  • Environmental Factors: Environmental factors such as cold weather or exposure to wind might contribute to nerve inflammation.

  • Autoimmune Reaction: In some cases, an autoimmune reaction—where the immune system mistakenly attacks healthy tissues—might lead to facial nerve inflammation.

  • Other Viral Infections: Besides HSV, other viruses such as the varicella-zoster virus (which causes chickenpox and shingles) and Epstein-Barr virus (which causes mononucleosis) have also been suggested as potential triggers for Bell's Palsy.

What Causes Bell's Palsy

Diagnosis of Bell's Palsy


The diagnosis of Bell's Palsy is primarily based on a clinical evaluation of the symptoms and physical examination conducted by a medical professional, typically a physician or a neurologist.


Physical therapy for Bell's palsy and physical therapy exercises for Bell's Palsy can be immensely effective.


  • Medical History: The doctor will begin by gathering information about your medical history, including when the symptoms started, how they have progressed, any recent illnesses, exposure to viruses, and any other relevant factors.

  • Physical Examination: The doctor will assess facial muscle strength, symmetry, and the ability to perform various facial expressions. They will check for weakness, drooping, and other signs of nerve dysfunction.

  • Rule Out Other Causes: Because there are other conditions that can cause facial paralysis, the doctor will want to rule out these possibilities. Conditions like stroke, tumors, trauma, and other neurological disorders can also affect facial nerve function.

  • Tests to Support Diagnosis: While the diagnosis of Bell's Palsy is mainly clinical, additional tests may be recommended to support the diagnosis and rule out other potential causes.

  • Response to Treatment: A key aspect of diagnosing Bell's Palsy is how the symptoms respond to treatment. If facial paralysis improves after treatment with medications like corticosteroids, it supports the diagnosis of Bell's Palsy.


How Bell's Palsy Can Be Treated With Physical Therapy


Physical therapy for Bell's Palsy can play a supportive role in treating the condition by helping to manage and improve muscle weakness and facial asymmetry.


  • Facial Muscle Strengthening: Physical therapists can design physical therapy exercises for Bell's Palsy to strengthen the affected muscles. These exercises are tailored to the individual's needs and may include resistance training, facial massage, and targeted facial movements to help prevent muscle atrophy and improve muscle tone.

  • Facial Exercises: Specific exercises are designed to improve the coordination of facial muscles, helping the affected side of the face move more naturally. These exercises can target various facial expressions, such as smiling, blinking, raising the eyebrows, and puffing the cheeks.

  • Range of Motion: Physical therapy can help improve the range of motion of the facial muscles, allowing for better control and symmetry of facial movements. Gently stretching and mobilizing the muscles can prevent stiffness and promote smoother movement.

  • Biofeedback: Some physical therapy techniques use biofeedback to help patients visualize and monitor their muscle movements. This can assist in learning proper muscle activation and coordination for more effective facial expressions.

  • Eye Protection and Care: Physical therapists can guide proper eye protection, particularly if the ability to close the eye on the affected side is compromised. They can recommend techniques to keep the eye moist and minimize the risk of eye damage.

How Bell's Palsy Can Be Treated With Physical Therapy

It's important to note that physical therapy for Bell's Palsy should be carried out under the guidance of a licensed and experienced physical therapist. The therapist will evaluate your condition, develop a tailored plan, and provide instructions on exercises to perform at home. Consistency and patience are key, as recovery from Bell's Palsy can take several weeks to months.


Physical Therapy Exercises for Bell's Palsy


Physical therapy exercises for Bell's Palsy are designed to help improve facial muscle strength, coordination, and movement on the affected side of the face. It's important to perform these exercises gently and consistently, as directed by a licensed physical therapist.


Eye Blinking Exercise


Gently close and open the eye on the affected side using your fingers to assist if necessary. Aim for a complete blink and try to blink at a comfortable and controlled pace.


Smile Exercise


Attempt a smile on the affected side by gently pulling the corner of your mouth upwards using your fingers. Hold the position for a few seconds and release. Repeat multiple times.


Eye Closure Resistance Exercise


Close the eye on the affected side and gently press your palm against the closed eyelid. Hold for a few seconds, and then release the pressure. Repeat several times.

Physical Therapy Exercises for Bell's Palsy

Eyebrow Raise Exercise


Place your fingers above the eyebrow on the affected side and attempt to raise the eyebrow. Apply gentle resistance with your fingers as you try to lift the eyebrow. Hold for a few seconds, and then release. Repeat multiple times.


Cheek Puff Exercise


Puff out your cheeks on the affected side and hold for a few seconds. Then relax and repeat the puffing motion several times.


Tongue and Lip Mobility Exercise


Gently move your tongue from side to side and up and down in your mouth. Try to touch the corners of your mouth with your tongue. Additionally, move your lips in various positions to promote flexibility.


Remember that these exercises should be done gently and without straining. Over time, as your facial muscles regain strength and coordination, you can gradually increase the repetitions and intensity of the exercises.


After Bell's Palsy Recovery


After recovering from Bell's Palsy, it's common to experience various feelings and adjustments. While many people achieve near-complete recovery, some individuals may have residual effects or slight facial differences.


It's important to remember that recovery from Bell's Palsy can take time. Facial muscles may continue to improve and adapt for several months after the initial symptoms have subsided.


Some individuals might have residual effects such as mild weakness, muscle stiffness, or subtle facial asymmetry even after recovery. These effects are usually minimal and may not be noticeable to others.

After Bell's Palsy Recovery

Even after recovery, it's a good idea to stay in touch with your healthcare provider. They can monitor your progress, provide guidance on any ongoing concerns, and offer recommendations for maintaining facial muscle health. Regular exercises can help maintain facial muscle strength and prevent muscle atrophy.


If residual effects are causing cosmetic concerns, you might consider consulting a dermatologist, cosmetic surgeon, or specialist in facial aesthetics.


Seeking support from friends, family, or a mental health professional is essential if the person is struggling emotionally.
