Welcome to the International Spasticity Society!

The International Spasticity Society (ISS) is a global community united by one mission: to “X-out” spasticity and improve the lives of millions worldwide. By connecting physicians, trainees, researchers, industry leaders, patients, and caregivers, the ISS and SPASTICITY X foster collaboration, innovation, and shared learning across disciplines and across borders. Members of the ISS share a common commitment to improving care and enhancing quality of life for patients living with spasticity and sensorimotor disorders.

SPASTICITY X is an international, interdisciplinary, three-day symposium dedicated to advancing the science and treatment of spasticity. Bringing together clinicians, researchers, patients, and key stakeholders, the event unites leading experts in spasticity and sensorimotor disorders with a shared mission: to “X-out” spasticity and improve the lives of millions worldwide.

The symposium provides a dynamic platform to analyze current and emerging research, evaluate treatment protocols, and foster collaboration across disciplines. Through thoughtful debate, innovative thinking, and open discussion of controversial topics, participants will work toward building consensus and shaping the future of spasticity management. Ultimately, SPASTICITY X aims to drive meaningful progress in patient care and enhance outcomes for those affected by spasticity.

We hope you will join us for the 2nd International Symposium 31 March–3 April 2027 in Barcelona!

I look forward to you being part of this effort to push boundaries and reimagine what’s possible in spasticity care.
