Juvenile idiopathic arthritis (JIA) is the name given to the many types of arthritis that affect children below the age of sixteen. As this is also a critical growth window for kids, JIA has the potential to negatively (and permanently) interfere with a child’s growth and bone development.
JIA is caused by the body’s immune system attacking its own cells – much like other types of arthritis such as rheumatoid arthritis. It is not currently known why JIA develops (hence the name!) but there is evidence to suggest that genetic history may make you more vulnerable – though it is not considered to be a hereditary disease. Certain environmental factors (like viruses or bacteria) can trigger the disease to activate.
There are many different types of JIA, each with different symptoms, prognosis and progression. Some of these types can be outgrown so the symptoms do not continue into adulthood. The most common types include:
Most of the types of arthritis in kids include flare-ups of symptoms, where kids alternate periods of being symptomatic with being asymptomatic. This can be accompanied by common symptoms such as:
While there’s no cure for juvenile idiopathic arthritis, medical treatments focus on limiting the symptoms during flare-ups to help children live a normal life. This is a multidisciplinary healthcare team approach, achieved with physical therapy, medications and, in rare cases, surgery.
As podiatrists, our goal is to help children remain mobile and active while improving or maintaining their muscle and joint function. As kids love to run and play, it’s important to help them keep up with their peers and participate in social activities wherever possible.
Every child under our care has a tailored treatment plan specific to their symptoms and how their arthritis is affecting them during and in-between flares. We’ll help with:
