Is it advisable to do exercise when affected by Larsen syndrome? Which activities would you suggest and how intense should they be?

Physical activity is highly recommended for individuals with Larsen syndrome to maintain joint stability, improve muscle strength, and support overall mobility. While joint hypermobility and skeletal abnormalities require careful management, low-impact, supervised exercise programs are essential for managing the long-term musculoskeletal effects of Larsen syndrome.

Is exercise safe and beneficial for people with Larsen syndrome?

For those living with Larsen syndrome, exercise is not only safe but vital. Because Larsen syndrome is characterized by joint dislocations, skeletal dysplasias, and ligamentous laxity, maintaining a strong muscular "corset" around the joints is the best way to prevent further instability. Exercise helps mitigate the chronic pain associated with Larsen syndrome and provides significant psychological benefits by improving confidence and functional independence for our 58 community members who are currently navigating these challenges.

Which types of exercise are recommended for Larsen syndrome?

The goal of any exercise program for Larsen syndrome is to build strength without putting excessive stress on vulnerable joints. Low-impact activities that minimize repetitive high-impact force are preferred. Recommended activities include:

• Swimming and Water Aerobics: Water provides buoyancy, which reduces the weight-bearing load on joints while offering natural resistance to build muscle.


• Stationary Cycling: This allows for controlled, repetitive movement that strengthens the quadriceps and hamstrings, which are crucial for knee stability in Larsen syndrome.


• Core Strengthening: Pilates-inspired movements (modified for hypermobility) help stabilize the spine and pelvis, which are often affected by the skeletal changes seen in Larsen syndrome.


• Isometric Exercises: These involve contracting muscles without moving the joint, which is a safe way to build strength if a joint is currently inflamed or unstable.

What activities should be avoided with Larsen syndrome?

Individuals with Larsen syndrome should approach high-impact or contact sports with extreme caution. Activities involving sudden changes in direction, jumping, or heavy contact—such as soccer, basketball, or rugby—carry a high risk of joint subluxation or dislocation. Additionally, extreme stretching or "yoga poses" that push joints to their end-range should be avoided, as the ligamentous laxity inherent to Larsen syndrome makes overstretching counterproductive to joint stability.

How can I start an exercise program safely?

Before beginning any new regimen, you must obtain medical clearance from your orthopedist or a physical therapist familiar with connective tissue disorders or skeletal dysplasias. Start with a "low and slow" approach: begin with 5–10 minutes of low-intensity activity and increase duration by no more than 10% per week. On "difficult days" when joint pain or fatigue from Larsen syndrome is high, utilize pacing strategies: reduce the intensity to restorative movements or gentle range-of-motion exercises rather than stopping activity entirely.

What is the role of physical therapy?

Physical therapy is the cornerstone of management for Larsen syndrome. A specialized therapist can create a personalized program that addresses specific areas of instability, such as the hips, knees, or cervical spine. They can teach you how to perform movements with proper biomechanical alignment, ensuring that your muscles—rather than your joints—are doing the work. Regular sessions also allow for real-time adjustments as your body’s needs change.
