Visual illusion proves effective in relieving knee pain for people with osteoarthritis

In a new study published in the journal Peer J this week, researchers at UniSA’s Body in Mind Research Group have found people suffering osteoarthritis in the knees reported reduced pain when exposed to visual illusions that altered the size of their knees.

UniSA researcher and NHMRC Career Development Fellow, Dr Tasha Stanton says the research combined visual illusions and touch, with participants reporting up to a 40 per cent decrease in pain when presented with an illusion of the knee and lower leg elongated.

“We also found that the pain reduction was optimal when the illusion was repeated numerous times — that is, its analgesic effect was cumulative,” Dr Stanton says.
