Psoriatic arthritis and exercise

What the research found.

• The review of exercise in psoriatic arthritis could give no pooled figure of any kind. What the trials tested, and what they measured, varied too much for anybody to add them together. What it does report is that aerobic and weight work improved heart and blood sugar risk, and improved disease measures too.

• The 2018 EULAR activity advice judged the general public activity targets fit for people with inflammatory arthritis and with osteoarthritis. Psoriatic arthritis is one of the diseases in that first group. So the advice applies to you squarely rather than reaching you by borrowing from some other illness.

• One group of patients had psoriatic arthritis that was mostly quiet or nearly quiet, and even so 61.5 percent of them were still sleeping badly. In rheumatoid arthritis the figure was 63.7 percent. In axial spondyloarthritis it came out at 66.7 percent, which is the highest of the three.

• Sleep apnea turned up a good deal more often in psoriatic arthritis, at a ratio of 1.75. The true value for it is somewhere from 1.35 to 2.26. That range doesn't touch 1 anywhere, which is what makes the excess real rather than an accident of the sample.

A review that couldn't pool its own trials

The review of exercise in psoriatic arthritis reached a verdict about the research rather than about the exercise. It could give no pooled figure, because what the trials tested varied too much to add together, and so did what they measured. That's the honest place to start reading any of it.

What it does report in words is that aerobic and weight work improved heart and blood sugar risk, and that they improved disease measures too. That's a direction to head in with no size attached to it. It's a weaker statement than a pooled figure, and it's still a statement.

Its title says better research is needed, which is an unusually blunt thing for a paper to say about its own subject. Our record for it puts the position well enough. The honest answer is that the evidence here is thin rather than missing altogether.

What applies to you squarely rather than by borrowing

Several pages on this site have to label the 2018 European activity advice as borrowed advice. That advice judged the general public activity targets fit for people with inflammatory arthritis and with osteoarthritis. Vasculitis is neither of those things, and neither is Sjogren disease.

Psoriatic arthritis is an inflammatory arthritis, so that advice applies to you squarely rather than by borrowing. That puts the exercise advice for this illness on firmer footing than the advice in the rarer diseases covered elsewhere here. It's a distinction worth knowing about when somebody quotes a guideline at you.

It's a guideline built on a research review plus expert agreement rather than a trial, so it comes with no effect size of its own. What it settles is two things in particular. Your diagnosis isn't a reason to move less, and the targets written for everybody are held to apply to you.

The heart case, which is the strongest part

The review found gains in heart and blood sugar risk rather than only in disease measures. That's the part of the case for exercise here with the least doubt over it. Heart risk is high across all the inflammatory arthritis illnesses, so here is a real reason to exercise that doesn't rest on your joints at all.

Skin-care guidance adds one more thing, which is that losing weight improves how well treatment works in psoriasis and psoriatic arthritis. It backs a Mediterranean way of eating as well. That's practical guidance drawing on the wider research rather than a pooled trial figure in this illness, and it points where the review points.

Read those together and the case comes out like this. Aerobic and weight work in this disease rest more on the heart and the blood sugar than on the joints. That's a duller argument than a disease effect would be, and it's also the better-supported one.

Sleep, and why more exercise may not fix the tiredness

Sleep in psoriatic arthritis is worse than the joints alone would explain. One group of patients had disease that was mostly quiet or nearly quiet, and even so 61.5 percent of them still slept badly. In rheumatoid arthritis it was 63.7 percent, and in axial spondyloarthritis it was 66.7 percent.

Sleep apnea turned up more often too, at a ratio of 1.75. The true value is somewhere from 1.35 to 2.26, and that range doesn't touch 1, so the excess is real. Sleep apnea also appears in a different class from most tiredness advice, because a doctor can find it and a doctor can treat it.

Nothing in this illness has tested whether exercise lifts tiredness. So if you stay tired, getting checked for sleep apnea is more likely to help than adding sessions. That's one specific thing to ask about rather than a vague one.

What to do with no program to follow

Build from where you are, and put in both aerobic work and strength work. That's what the review points at, and it's what the public targets involve. There's no frequency, length, or intensity to give you for psoriatic arthritis in particular, because the research that would supply those hasn't been gathered.

Tell whoever supervises you which joints are affected, because this disease hits fingers, toes, tendon attachments, and the spine. The mix differs a great deal from one person to the next. A plan built for knees and hips may be wrong for somebody whose trouble is in the fingers and the heels.

Raise heel or foot pain, because doctors call that enthesitis and training through it makes it worse. It means swelling where tendons and ligaments attach to bone. It's typical of this disease, it doesn't behave like ordinary tendon soreness, and this site holds no source on treating it, which is a hole worth naming. So get new pain there looked at, because folding it into a training plan hides the thing that needs seeing.

Common misconceptions.

Cautions specific to this condition.

• Tell whoever supervises you which joints are affected. This disease hits fingers, toes, tendon attachments, and the spine, and the mix differs a lot from person to person.
• Raise heel or foot pain, because training through it is how a small problem becomes a long one. Swelling where tendons attach to bone doesn't behave like ordinary tendon soreness.
• Ask about sleep apnea if you stay tired. Its ratio here is 1.75, and a doctor can treat it.
• Expect no program written for this disease, because there isn't one. Build from what you can do now, because a plan somebody found online was written for somebody else.
• Raised heart risk is the part of the case for exercise here with the least doubt over it, and work that lifts your heart rate is what the evidence on that risk is built from.
• Mention any change in your skin or nails. This is one disease, not two, and the skin belongs in a rheumatology visit.
