The parent of a child diagnosed with Juvenile Idiopathic Arthritis asks about exercises that would be good for the child. Which of the following would promote mobility.

Choice A rationale Jogging involves high-impact, repetitive loading on the joints of the lower extremities, specifically the hips, knees, and ankles. This type of high-impact exercise can exacerbate inflammation and cause further articular damage in a child diagnosed with Juvenile Idiopathic Arthritis (JIA), thus it is generally discouraged to prevent joint trauma. Choice B rationale Jumping rope is considered a high-impact, plyometric activity that places significant stress on multiple joints, including the ankles, knees, and hips, due to the forceful landings. This impact can aggravate the symptoms of JIA, such as joint pain and swelling, and contribute to progressive cartilage and bone erosion over time. Choice C rationale Tennis is a sport that involves rapid, jarring movements, quick changes in direction, and high impact on weight-bearing joints, as well as repetitive, forceful movements in the wrists, elbows, and shoulders. These actions can increase mechanical stress and shearing forces on inflamed joints, making it an unsuitable exercise choice for a child with JIA. Choice D rationale Swimming is an excellent form of exercise for children with JIA because the buoyancy of the water provides a non-weight-bearing environment, significantly reducing the impact and stress on inflamed joints. This allows for improved range of motion, muscle strengthening, and cardiovascular conditioning without increasing joint pain or damage.
