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

Regular physical activity is generally recommended for individuals with Simpson-Golabi-Behmel syndrome (SGBS) to support cardiovascular health, muscle tone, and overall well-being, though it must be approached with caution due to the syndrome's multisystem nature. Because Simpson-Golabi-Behmel syndrome involves diverse clinical manifestations—including potential cardiac anomalies and skeletal abnormalities—all exercise programs should be cleared by a multidisciplinary medical team before initiation.

Is exercise safe for those living with Simpson-Golabi-Behmel syndrome?

Exercise is not contraindicated for most individuals with Simpson-Golabi-Behmel syndrome, but it requires a personalized approach. Since SGBS is characterized by overgrowth, macroglossia, and potential structural heart defects or vertebral anomalies, the intensity of activity must be tailored to the individual's specific health profile. For the 26 members of the DiseaseMaps.org community living with Simpson-Golabi-Behmel syndrome, physical activity is often used to manage joint stability and improve motor coordination, provided that cardiac and orthopedic risks have been thoroughly evaluated by specialists.

What types of exercise are recommended for Simpson-Golabi-Behmel syndrome?

Low-to-moderate impact activities are typically the safest and most beneficial for individuals with Simpson-Golabi-Behmel syndrome. These activities help build stamina without placing excessive stress on the musculoskeletal system. Recommended activities include:

• Walking: A consistent, low-impact way to improve cardiovascular endurance.


• Swimming or Aquatic Therapy: Excellent for those with joint or vertebral issues, as water provides buoyancy and reduces impact.


• Gentle Yoga or Stretching: Helps maintain flexibility and can assist with the motor delays sometimes associated with Simpson-Golabi-Behmel syndrome.


• Resistance Training (Supervised): Using light weights or resistance bands can help build muscle tone, but only under the guidance of a physical therapist to ensure proper form.

Which activities should be approached with caution?

High-impact sports, such as contact football, competitive wrestling, or heavy weightlifting, should be approached with extreme caution or avoided, particularly if the individual has known vertebral abnormalities or cardiac issues associated with Simpson-Golabi-Behmel syndrome. Activities that involve rapid changes in direction or high fall risks can exacerbate underlying skeletal vulnerabilities. Always monitor for symptoms such as dizziness, shortness of breath, or chest pain during any activity, as these may be red flags related to the cardiovascular features of Simpson-Golabi-Behmel syndrome.

How can physical therapy support mobility?

Physical therapy is a cornerstone of management for Simpson-Golabi-Behmel syndrome. A physical therapist can conduct a functional assessment to identify specific muscle weaknesses or gait abnormalities. They can then design a structured program that focuses on balance, core stability, and pacing strategies. On days when fatigue or symptoms are more pronounced, your therapist can help you adjust your activity level, teaching you how to "pace" your movement rather than stopping exercise entirely, which helps prevent deconditioning while respecting your body’s limits.

Next steps

• Consult your cardiologist and orthopedist to ensure you have medical clearance for physical activity.


• Request a referral to a pediatric or adult physical therapist familiar with genetic overgrowth syndromes.


• Start with a "low and slow" approach: begin with 5–10 minutes of light activity and monitor your heart rate and energy levels for 24 hours.


• Connect with the 26 members on DiseaseMaps.org to share experiences regarding mobility and exercise adaptations.
