Rigidity and stiffness in Parkinson’s

Rigidity, meaning stiff or inflexible muscles, is one of the most common motor symptoms of Parkinson’s, along with tremor and slowness of movement (bradykinesia). Research on its prevalence varies, but rigidity affects the large majority of people with Parkinson’s

Everyone’s experience is different, but rigidity can often start with aching, stiffness or a feeling of muscle weakness. This usually begins in one arm, before spreading to the rest of the body. Muscles may feel weak, although true strength is usually preserved. It is the extra effort needed to move against the stiffness that makes them feel weak.

Rigidity happens because Parkinson’s disrupts the brain circuits that regulate muscle tone, the background tension your muscles hold even at rest. Without that regulation working properly, muscles stay more tense than they should, and resist being moved. This is why a doctor can feel the stiffness when they move your arm for you, even when you are relaxed and not trying to help or resist.

On this page you can find information about all the signs and symptoms of rigidity and stiffness in Parkinson’s, how it is diagnosed and treated, and what you can do to provide relief at home.

Rigidity symptoms

Over time, rigidity can prevent muscles from functioning as they should, which can lead to symptoms such as:

• Stiff and/or inflexible muscles
• Stooped posture
• Pain and muscle cramps
• Difficulty turning when walking, turning in bed and getting out of a chair or bed
• Reduced arm swing when walking
• Difficulty with everyday activities like dressing, cutting food and writing
• Difficulties with chewing, swallowing, breathing and speaking clearly
• Reduced facial expression or a mask-like face (hypomimia)
• Handwriting becoming small and cramped (micrographia)

Everyone’s experience is different but rigidity often starts in one arm, spreads to the leg on that side and then to the trunk and other side of the body. Rigidity will progress faster in some people than in others.

Rigidity is different from ordinary stiffness after exercise or from arthritis. It does not ease off with movement in the same way, and it is present even when you are completely relaxed. It is also different from spasticity, the stiffness seen after a stroke. In Parkinson’s, the resistance is even and steady throughout the movement, rather than occurring suddenly.

Shoulder pain and stiffness (frozen shoulder) is often the earliest sign, and frequently occurs before diagnosis. Neck and back pain is also very common, and frequently mistaken for a spinal problem.

What is hypomimia or ‘Parkinson’s disease face’?

Hypomimia – also known as “facial masking” – is a loss or reduction of facial expressiveness, including emotional expressions. It is characterised by slower and less pronounced facial movements.

In Parkinson’s, it is believed to be caused by a loss of motor control that affects the movement of muscles in the face, meaning facial expressions may be slowed or reduced in size.

Parkinson’s affects everyone differently. While hypomimia may be very noticeable in some individuals, others may experience more subtle changes in their facial expressions.

How is rigidity in Parkinson’s tested or diagnosed?

A doctor will test for rigidity by flexing and extending your relaxed wrist and the elbow joint. He or she will look for sustained (lead pipe) rigidity when performing these tests or intermittent (cogwheel) rigidity if you also have tremor.

Doctors can also test the neck, and legs and often ask you to move your other arm (for example, opening and closing the opposite hand) while they move the limb being tested. This is called an activation manoeuvre, and it brings out mild rigidity that would otherwise be missed.

Is rigidity always linked to Parkinson’s disease?

No. Muscle stiffness is extremely common, and most people who experience it do not have Parkinson’s. Stiffness can be caused by many everyday things like aging, arthritis, a frozen shoulder, an injury, poor posture, long periods of sitting, or simply an unaccustomed bout of exercise.

It can also occur in a number of other medical conditions, and as a side effect of some medications, including certain antipsychotic and anti-sickness drugs.

The stiffness in Parkinson’s has particular features that set it apart:

• It is present even when you are completely relaxed. A doctor can feel it when they move your arm for you, without you helping or resisting.
• It usually starts on one side of the body, most often in an arm, and stays worse on that side for a long time.
• It does not ease off with movement in the way that morning stiffness or arthritis often does.
• Most importantly, it rarely appears on its own. In Parkinson’s, rigidity is almost always accompanied by other signs, particularly slowness of movement (bradykinesia), and often a tremor at rest, a reduced arm swing on one side, smaller handwriting, a quieter voice, or a change in facial expression.

What can help treat rigidity in Parkinson’s?

If you are experiencing rigidity, it is best to start by talking to your doctor. Rigidity tends to respond well to medication, for example levodopa, but as with all Parkinson’s medications, what works for one person may not work for another. Be prepared for your doctor to try several approaches to see what works best for you.

They may refer you to a doctor who specialises in movement disorders or to a physiotherapist, occupational therapist or speech and language therapist depending on the country in which you live and your individual needs. Seeing a therapist soon after problems begin is more likely to result in successful treatment.

Stiffness that clearly worsens as a dose wears off is a useful signal to report as it suggests medication timing needs review, rather than that the disease has suddenly progressed. This is genuinely actionable.

Additional therapies for rigidity

Additional therapy treatments can be used to manage the impact of rigidity on daily functioning. Access can vary from country to country but can include:

• A physiotherapist can advise on exercises – such as pilates, Lee Silverman BIG movements, hydrotherapy, yoga etc to maintain or improve both mobility and the range of movement in your muscles and joints. They can also suggest strategies to perform daily activities in a more effective way, for example how to roll over in bed or get up from a chair.
• An occupational therapist or physiotherapist will be able to advise on devices and aids to help you in your everyday life. An occupational therapist will also be able to suggest changes to your routine to help you to stay mobile and independent.
• A speech therapist can teach you exercises to help with speech and communication and keep the muscles associated with these activities flexible. They can also teach you breathing exercises to relax and strengthen chest muscles, and improve breathing and swallowing difficulties.
• You may find massage therapy helps to relieve the discomfort of stiffness and cramps, and reduces muscle pain.

What can I do at home to relieve rigidity?

As well as speaking to your healthcare team, there are ways you can help to manage and reduce rigidity in Parkinson’s yourself.

Staying active

Try to keep active, as this will help you maintain flexibility, mobility and independence. Regular exercise can also help to strengthen muscles and alleviate the pain and aches that often accompany rigidity.

Suggestions for an active lifestyle to help rigidity:

• Continue your normal routine and daily activities for as long as you are able
• Not staying in the same positions for long periods of time is key to managing the increase of rigidity and discomfort.
• Follow a simple exercise programme to keep your muscles flexible and strong. Muscle stretches and chair-based exercises may help to ease stiffness and soreness
• Adjust your routine so that you do things that might tire your muscles when you feel least stiff (usually when your medication is working well).
• Stretch up tall each time you stand up, and if you’ve been sitting for a while, loosen up by twisting your body from side to side two or three times, then swing each leg backwards and forwards
• Stiffness varies from day to day, and a difficult day does not mean you are going backwards. Keeping some record of what helps, which exercises, which times of day, how it relates to your medication.

Coping strategies for rigidity

Many people have discovered and developed activities and exercises that help with rigidity and mobility – their own personal ‘coping strategies’.

Although these won’t work for everyone, some of these tips and tricks may help you to discover and develop strategies of your own.

What is lead pipe rigidity in Parkinson’s disease?

Lead pipe rigidity is stiffness that feels smooth and constant throughout a movement. When a neurologist examines you, they will take your relaxed arm and move it slowly at the wrist or elbow. In lead pipe rigidity, they feel a steady, even resistance all the way through the movement like bending a lead pipe, which gives way slowly and uniformly rather than springing back.

Two features are important, and they are what distinguish rigidity from ordinary stiffness:

• It is there even when you are completely relaxed. You are not tensing or resisting; the resistance is present regardless.
• It is the same in both directions and throughout the range. It does not catch, and it does not depend on how fast the limb is moved.

This is the pure form of rigidity in Parkinson’s, and it is one of the cardinal motor signs the doctor is looking for. It is felt by the examiner more than by you, which is why the stiffness you feel and the stiffness a doctor finds do not always match.

If mild rigidity is not obvious, your doctor may ask you to move your other hand ( opening and closing it, or drawing circles in the air) while they test the limb. This is called an activation manoeuvre, and it brings out subtle rigidity that would otherwise be missed. It is a normal part of the examination, not a sign that something is wrong.

What is cogwheel rigidity in Parkinson’s disease?

Cogwheel rigidity is stiffness that feels ratchety rather than smooth, as though the joint is moving over a series of small catches, like a cogwheel turning.

It occurs when rigidity and tremor are present together. The underlying stiffness is constant, but the tremor interrupts it rhythmically, producing the regular catching sensation the examiner feels. In other words, cogwheeling is not a separate kind of stiffness. It is lead pipe rigidity with a tremor superimposed on it.

Two things are worth knowing:

• Cogwheeling is not worse than lead pipe rigidity. It does not mean more advanced disease, and it does not mean a different diagnosis. It simply reflects the presence of tremor alongside the stiffness.
• Cogwheeling alone does not diagnose Parkinson’s. It can be felt in people with essential tremor and in other conditions where a tremor is present without true rigidity. What matters diagnostically is whether there is genuine, sustained resistance underneath the ratcheting and, above all, whether slowness of movement (bradykinesia) is also present. A diagnosis of Parkinson’s is never made on stiffness alone.

Do people with Parkinson’s experience nuchal rigidity?

Nuchal rigidity is not a feature of Parkinson’s. It is a medical emergency. Nuchal rigidity is a specific clinical sign meaning that the neck strongly resists being bent forward, because doing so stretches the inflamed lining of the brain and spinal cord. It is associated with meningitis and with bleeding around the brain (subarachnoid haemorrhage).

Seek urgent medical help (call emergency services) if a stiff neck comes on suddenly and is accompanied by fever, severe headache, sensitivity to light, confusion, drowsiness, or a rash. This is not Parkinson’s, and it needs immediate assessment.

Neck stiffness in Parkinson’s is a different thing entirely. People with Parkinson’s very commonly have a stiff neck but this is axial rigidity, part of the general stiffness of the condition. It differs from nuchal rigidity in every important respect:

• It develops gradually, over months and years, rather than suddenly.
• It is not painful to bend forward in the way meningitis is; it is a resistance to movement in all directions.
• It comes with the other features of Parkinson’s like slowness, stooped posture, reduced arm swing.

Neck stiffness in Parkinson’s contributes to a forward head position, neck and shoulder pain, difficulty turning to look over your shoulder (which matters for driving), and difficulty turning over in bed. It usually responds, at least partly, to Parkinson’s medication, and physiotherapy, mobility and posture work all help.
