The Vestibular Disorders Association (VeDA) joins the international vestibular community in mourning the loss of Alain Sémont, the pioneering French physiotherapist who developed the Semont maneuver for benign paroxysmal positional vertigo (BPPV) and helped shape the modern field of vestibular rehabilitation.
Sémont died on August 8, 2026, at the age of 81. His passing marks the loss of an influential clinician, educator, and innovator whose work changed how vestibular disorders are treated around the world.
For VeDA, his passing is especially meaningful. Sémont served for many years on VeDA’s Medical and Scientific Advisory Board, generously sharing his expertise in support of our mission and the patients and healthcare professionals we serve.
Alain Sémont and the Semont Maneuver for BPPV
Sémont is best known around the world for developing the Semont maneuver, also known as the Semont liberatory maneuver, for the treatment of benign paroxysmal positional vertigo (BPPV).
The origins of the maneuver date to the late 1970s, when Sémont observed that a particular movement produced a remarkable resolution of positional vertigo in a patient. After repeating the technique with other patients and refining it through further study, he developed what became known as the liberatory maneuver and, eventually, the Semont maneuver.
Sémont and his colleagues formally described the maneuver in 1988. It became one of the foundational repositioning treatments for posterior canal BPPV and continues to be used by vestibular clinicians around the world.
Around the same period, American otolaryngologist Dr. John Epley was developing another approach to repositioning the displaced inner-ear particles that cause BPPV. The Epley maneuver and Semont maneuver use different sequences of head and body movements, but both grew from the recognition that BPPV could be treated mechanically by moving displaced particles out of the affected semicircular canal. Together, these pioneering approaches helped transform BPPV from a condition that could be frustrating and difficult to manage into one that, for many patients, can be treated effectively with a relatively brief series of movements.
For patients, the importance of this contribution is difficult to overstate. BPPV can cause sudden, frightening attacks of vertigo triggered by changes in head position. Repositioning maneuvers such as Sémont’s gave clinicians a way to address the underlying mechanical problem in the inner ear through a relatively brief physical treatment.
Millions of patients have benefited from the clinical advances that grew from this work.
Helping Build the Field of Vestibular Rehabilitation
Sémont’s influence extended well beyond the maneuver bearing his name. He was an early pioneer of vestibular rehabilitation therapy (VRT) and is credited with introducing the term “vestibular rehabilitation” itself.
At a time when treatment of dizziness and imbalance was far less developed than it is today, Sémont helped establish vestibular rehabilitation as a specialized area of clinical practice. He founded the International Society for Vestibular Rehabilitation (SIRV) and was deeply involved in educating clinicians and advancing knowledge about the assessment and treatment of vestibular disorders.
His influence can therefore be measured not only in the techniques he developed, but also in the generations of vestibular professionals he taught and inspired.
A Valued Member of the VeDA Community
VeDA was fortunate to benefit directly from Sémont’s knowledge and commitment to people living with vestibular disorders.
As a longtime member of VeDA’s Medical and Scientific Advisory Board, he contributed to an international network of clinicians and researchers who have helped VeDA ensure that patients receive trustworthy, scientifically grounded information about vestibular diagnosis, treatment, and rehabilitation.
In a 2020 editorial for VeDA, Sémont shared his perspective on vestibular rehabilitation and the specialized understanding required to treat disorders involving the complex interaction of the vestibular, visual, and balance systems.
His relationship with VeDA reflected something central to his career: a commitment not simply to developing new techniques, but to expanding knowledge about vestibular disorders and improving the care patients receive.
The Lasting Legacy of Alain Sémont
Few healthcare professionals have the distinction of seeing their name become part of the everyday vocabulary of their field. Around the world, clinicians teach and perform the Semont maneuver every day. Many of the patients receiving that treatment may never know the story of the French physiotherapist whose curiosity and careful clinical observation helped make their recovery possible.
But within the vestibular community, Alain Sémont’s legacy is unmistakable.
He helped transform how BPPV is treated. He helped establish vestibular rehabilitation as a specialized discipline. He educated and inspired generations of clinicians. And through his service to organizations such as VeDA, he helped extend that knowledge to the patients who needed it most.
VeDA is deeply grateful for Alain Sémont’s many years of service to our Medical and Scientific Advisory Board and for his extraordinary contributions to the global vestibular community.
We extend our heartfelt condolences to his family, friends, colleagues, students, and the many patients and professionals whose lives were touched by his work.
His name will remain part of vestibular medicine. More importantly, his work will continue to improve patients’ lives for generations to come.
