Is it advisable to do exercise when affected by STXBP1? Which activities would you suggest and how intense should they be?

Physical activity is generally highly beneficial for individuals with STXBP1-related disorders, as it supports motor development, bone density, and emotional regulation. While exercise is not contraindicated, all programs must be tailored to the individual’s seizure threshold, hypotonia, and coordination challenges under the guidance of a multidisciplinary care team.

Is exercise safe for those living with STXBP1?

Yes, exercise is encouraged for people with STXBP1 to help manage common features like low muscle tone (hypotonia) and ataxia. For the 271 members of the DiseaseMaps community, movement often acts as a tool to improve daily function. However, because STXBP1 is characterized by developmental delay and epilepsy, activities must be supervised to ensure safety in the event of a seizure or loss of balance.

What types of exercise are most beneficial?

Low-impact, controlled movements are typically the safest starting point. Focus on activities that build core stability and coordination, which are essential for those managing STXBP1. Recommended activities include:

• Swimming or water therapy: Provides buoyancy and resistance, which is excellent for individuals with hypotonia.


• Adaptive yoga or stretching: Helps maintain joint range of motion and provides sensory regulation.


• Guided walking: Improves cardiovascular health and gait stability, provided there is appropriate supervision.


• Core strengthening: Essential for building the trunk stability needed for better posture and motor control.

How should an exercise program be adapted?

Progression should be gradual to avoid overexertion, which can sometimes trigger fatigue or increase seizure risk in some STXBP1 patients. On "low-energy" days, utilize pacing strategies such as shorter, more frequent sessions rather than one long, intense workout. Always prioritize a safe environment, avoiding activities with high fall risks, such as climbing or cycling on uneven terrain, without specialized equipment.

What is the role of physical therapy in STXBP1 care?

Physical therapy is a cornerstone of STXBP1 management. A physical therapist can create a customized plan that addresses specific motor deficits, provides sensory input, and teaches caregivers how to assist with movement safely. Consistent engagement with a therapist helps maximize the developmental potential of those diagnosed with STXBP1.

Next steps

• Consult your neurologist and physical therapist before starting a new exercise regimen.


• Request a referral to a pediatric or neurological physical therapist familiar with neurodevelopmental disorders.


• Connect with the 271 members on DiseaseMaps.org to share experiences regarding mobility and activity.
