Can children with JIA take part in sports? 

A common misconception regarding Juvenile Idiopathic Arthritis (JIA) is that physical activity should be restricted to protect the joints. In reality, the opposite is true. Clinical specialists in the UK actively encourage children with JIA to participate in sports and physical activities as a fundamental part of their treatment and overall wellbeing. While some modifications may be necessary during periods of high disease activity, staying active is vital for maintaining joint function and supporting a child’s social development. This guide explains how children can safely engage in sports while managing an inflammatory condition.

• The role of the paediatric physiotherapist in sports readiness 

Children with JIA can and should take part in sports, as regular exercise is essential for strengthening the muscles that support the joints and maintaining a healthy range of motion. Most children with JIA are able to participate in mainstream PE lessons and competitive sports once their inflammation is well-controlled with medical treatment. The NHS highlights that exercise is an important part of treatment for JIA, as it helps to keep joints moving and muscles strong, which can reduce pain in the long term. 

The Benefits of Sports for Children with JIA 

Physical activity provides a range of biological and psychological benefits for children with arthritis. When a child is active, the movement helps to circulate synovial fluid within the joint, which acts as a natural lubricant and nutrient source for the cartilage. Furthermore, building strong muscles around a joint provides a “natural brace,” absorbing impact and reducing the mechanical stress placed on the inflamed area. 

Beyond the physical benefits, sports are a crucial part of a normal childhood. Participating in team activities helps children with JIA feel included and builds their confidence, preventing the social isolation that can sometimes accompany chronic illness. Achieving sports-related goals provides a sense of mastery and resilience, proving to the child that their diagnosis does not define their physical capabilities. 

Choosing the Right Sports 

While almost any sport can be made accessible, some activities are naturally more “joint-friendly” for children with JIA. Low-impact sports are often the best choice during the initial stages of treatment or when a child is recovering from a flare, as they provide cardiovascular benefits without heavy jarring of the weight-bearing joints. 

Swimming and Hydrotherapy

The buoyancy of the water supports the body, allowing for a full range of movement without any impact on the joints.

Cycling

This provides a rhythmic, controlled movement that is excellent for knee and hip mobility.

Tai Chi or Yoga

These practices focus on balance, flexibility, and core strength, which are vital for joint stability.

Walking and Hiking

A simple way to stay active, provided the child has supportive, well-cushioned footwear.

Team Sports

Many children successfully play football, netball, or hockey; however, they may need to “pace” their involvement during games.

Managing Sports During a Flare 

During an inflammatory flare, when joints are swollen, hot, and particularly painful, the approach to sports must change. Pushing through severe inflammatory pain is not recommended, as it can lead to further irritation of the joint lining. However, “absolute rest” is also discouraged, as it leads to stiffness. 

The strategy during a flare is to switch to gentle “range-of-motion” exercises. These involve moving the joint through its natural path without adding resistance or impact.¹⁰ A child might take a break from competitive match play but still participate in light warm-up drills or swimming. The National Institute for Health and Care Excellence (NICE) guidelines recommend that physical activity should be tailored to the individual’s current disease activity, with a focus on maintaining mobility during flares. 

Comparison of Sports by Impact Level 

This table helps parents and teachers understand how to categorize different activities based on the stress they place on the joints. 

Low Impact (Highly Recommended)	Moderate Impact (Monitor Closely)	High Impact (Modify During Flares)
Swimming / Hydrotherapy	Brisk Walking	Rugby / Football
Cycling / Spinning	Table Tennis	Gymnastics / Trampolining
Yoga / Pilates	Dancing	Long-distance Running
Rowing	Doubles Tennis	Basketball / Netball

Working with a Paediatric Physiotherapist 

A paediatric physiotherapist is a key member of the JIA care team. They can provide a “sports readiness” assessment, identifying any specific muscle weaknesses or joint limitations that might put the child at risk of injury. They can also provide tailored exercises to help the child prepare for the specific demands of their chosen sport, such as strengthening the ankles for football or improving wrist stability for racquet sports. 

Physiotherapists can also advise on the use of “joint protection” during sports.¹² This might include wearing supportive trainers with good arch support, using cushioned insoles, or using temporary splints or kinesiology tape during high-activity periods. Their goal is to empower the child to stay on the field or in the pool for as long as possible. 

Conclusion 

Sports are a vital and safe component of life for children with JIA.¹³ By choosing the right activities, practicing pacing, and working closely with their clinical team, children can enjoy the physical and social benefits of being active. The goal of modern JIA treatment is to ensure that every child has the opportunity to participate in the sports they love. If your child experiences a sudden severe flare, a high fever with a rash, or any sudden loss of movement after sport, call 999 immediately.
