What else do we know about PPS?
PPS can occur at any age and can be an issue for people who had either paralytic or seemingly non-paralytic Polio.
Research on who is most likely to experience PPS is not always clear and can be contradictory. Findings vary, but have shown that PPS may develop in a significant number of people with Polio.
It is suggested that PPS may affect more women than men.
People who have had fatigue or pain in the years since they contracted Polio, or where physical activity has caused extreme tiredness and pain, seem to be at increased risk of developing PPS, or may already be experiencing it.
PPS also seems to develop more quickly in people who had Polio during the epidemics of the 1950s.
What are the symptoms of PPS?
Symptoms may include the following:
- breathing problems
- swallowing problems
- muscle loss
- new or increasing weakness
- muscle fatigue
- muscle pain
- joint pain
- cold intolerance
- Sleep disturbance
- general fatigue
Other symptoms, such as urinary problems, may or may not be linked to PPS.
How is PPS diagnosed?
Unfortunately there is not a single test for PPS and it is important to make sure there is no other reason for the symptoms.
A number of factors will need to be considered before a doctor can tell you if you have PPS, including the following:
- Do you have a confirmed history of Polio?
- If you don’t know if you had Polio, did you ever come into contact with anyone who might have had it?
- Do you have any physical signs of having had Polio in the past?
- Have you had a period of recovery from Polio when your condition has not changed for a long time?
- Are you experiencing new or increasing weakness, abnormal muscle fatigue or new loss of muscle bulk?
- Are you getting pain in your joints?
- Are you having problems with breathing, sleeping and/or swallowing, or not being able to tolerate the cold?
- Is there any other medical explanation found for these symptoms?
It may be difficult to get a diagnosis of PPS because many healthcare professionals know very little about the condition, or even about Polio. Referral to a consultant neurologist, ideally with knowledge of Polio and PPS, may be the best way to get a diagnosis and advice.
The British Polio Fellowship has more information about PPS and a list of healthcare professionals with an interest in PPS, please contact our Support Service Team.
What tests might I have?
If your GP suspects that you may have PPS, they should consider the following tests:
- Full Blood Count (FBC)
- Biochemical profile
- Creatine kinase (CK)
- Thyroid function
- Inflammatory markers (ESR, CRP)
- Rheumatoid factor
- Anti-nuclear antibody (ANA)
- Uric acid
- Routine kidney function
- Liver function
- Serum calcium
- Serum vitamin D status
If the results of these tests are abnormal, you are more likely to have another condition that needs investigation, but this does not rule out the possibility of you having PPS as well.
In addition you may be referred for x-rays of:
Chest and spine
If you have these tests and your GP is still not sure that you have PPS, you may be referred to a hospital consultant. At this stage you may have some or all of the following tests to rule out other possible conditions or confirm the likelihood of PPS:
- electromyography (EMG) tests to see if Polio has damaged your nerves and muscles
- Sleep studies if you are having problems sleeping or feeling unusually tired
- Cardiological tests to check your heart rate and function
- Magnetic Resonance Imaging (MRI) of your spine
- Lung function tests to see how well you can breathe in and out
- Tests to investigate swallowing problems
You should remember that you may have PPS as well as other conditions, so not every health problem or symptom experienced will be related to PPS.
