To assess joint function in a child with arthritis, which activity would be considered beneficial?

Bicycle riding is considered beneficial for assessing joint function in a child with arthritis because it offers a low-impact form of exercise that promotes joint mobility without placing excessive stress on the joints. This activity allows for controlled movement, which can help to improve strength, flexibility, and endurance in an enjoyable and engaging way.

Cycling encourages the use of large muscle groups, enhances cardiovascular fitness, and can help in maintaining a healthy weight, all of which are important for children with arthritis. It also helps in reducing stiffness and improving overall joint function, making it easier for the child to perform daily activities.

Other options, such as prolonged sitting, would not facilitate joint movement and could lead to stiffness and deconditioning. Heavy weightlifting could impose significant stress on the joints, potentially leading to injury or exacerbation of symptoms. While walking activities can be beneficial, they might not provide the same level of engagement and enjoyment as bicycle riding, making it a preferred choice in this context.
