What Sports Are Safe for Osteogenesis Imperfecta?

Finding the right balance between safety and an active childhood is a common concern for parents of children with osteogenesis imperfecta (OI). While high-impact activities like football, hockey, and trampolining must be avoided, physical activity is essential for children with OI ^[1][1]. Aquatic therapy and swimming are highly recommended because water buoyancy protects the body while allowing for safe exercise ^[1][1]. Staying active helps children build strength and prevents a cycle of immobility that can actually weaken bones further ^[1].

Why Exercise Matters: Muscles as a “Natural Splint”

It might seem logical to heavily protect a child with fragile bones from physical exertion, but current medical consensus warns against overprotection ^[1][1]. A lack of physical activity removes the necessary stimuli for bone formation ^[1].

• The Muscle-Bone Connection: Research shows that in children with OI, muscle strength is directly linked to bone strength ^[2][2]. Muscle weakness can directly contribute to decreased bone mass ^[2][2].
• Creating a Natural Splint: Building core and limb muscles helps stabilize the joints, improve coordination, and smooth out movements ^[1][1]. Strong muscles act like a “natural splint,” providing internal support to fragile bones and giving individuals a feeling of physical stability ^[1][1].
• Breaking the Cycle: Fear of fractures often leads to immobility, which causes further muscle weakness and bone loss, ultimately increasing the risk of future fractures ^[1][1].

Safe and Recommended Activities

Exercise programs should always be personalized to the child’s specific type of OI, ideally under the supervision of a physical therapist. OI severity varies drastically—from mild (Type I) to severe (Type III)—meaning an activity that is safe for one child may not be safe for another.

• Aquatic Therapy and Swimming: Water provides buoyancy, which supports the body’s weight and significantly reduces the impact on bones and joints ^[1][1]. This allows children to engage in cardiovascular and muscle-strengthening exercises with a very low risk of injury.
• Low-Impact Exercises: Walking, stationary cycling, elliptical training, and tailored resistance band exercises are often safe ways to build endurance and muscle ^[1].
• Physical Therapy: An intensive, supervised physiotherapy program (often spanning 12 weeks to build initial strength) can safely improve a child’s aerobic capacity, though physical therapy is generally an ongoing aspect of managing OI ^[1].
• Managing Fatigue: Children with OI can experience muscle fatigue more quickly than their peers, which compromises their “natural splint.” Scheduled rest breaks during physical activity are an essential safety measure.

Activities and Equipment to Avoid

While maintaining an active lifestyle is crucial, certain activities and equipment pose an unnecessary risk of fracture.

• High-Impact and Contact Sports: Sports with a high risk of falls, physical collisions, or sudden bone displacement—such as football, hockey, gymnastics, and competitive martial arts—should be strictly avoided ^[1][1].
• Trampolines and Bouncers: Activities that involve repetitive jarring, jerking, or jumping carry a high risk of injury ^[1][1]. For toddlers with OI, equipment like bouncy houses, baby bouncers, jumperoos, swings, and baby walkers are specifically not recommended ^[1][1].
• Physical Education (P.E.) at School: Parents should work closely with the school to ensure recess monitors and P.E. teachers understand these restrictions. Ask for safe alternatives during contact sports, such as stationary biking or a walking program.

Crucial Note on Infant Handling

Because physical movement starts at birth, everyday handling is the first physical activity parents must navigate. Careful handling is critical to prevent fractures. Avoid pulling, twisting, or picking an infant up by the armpits or ribs ^[1]. Instead, always “scoop” the baby by supporting their head, shoulders, and buttocks with broad hands to distribute their weight evenly ^[1].
