Abstract Mal de Debarquement Syndrome (MdDS) is a rare balance disorder where individuals develop a persistent perception of phantom movement after a prolonged period of passive motion. A treatment method using visual stimuli in a nonportable physical chamber was used in a clinical setting. To make this method more accessible and portable, we developed a […]
Treatment of the MdDs: 1-Year Follow-UpFront Neurol. 2017 May 5;8:175. doi: 10.3389/fneur.2017.00175. eCollection 2017.Abstract: The mal de debarquement syndrome (MdDS) is a movement disorder, occurring predominantly in women, is most often induced by passive transport on water or in the air (classic MdDS), or can occur spontaneously. MdDS likely originates in the vestibular system and is unfamiliar […]
Readaptation of the vestibulo-ocular reflex relieves the mal de debarquement syndromeFront Neurol. 2014; 5: 124.Abstract: The mal de debarquement syndrome (MdDS), a continuous feeling of swaying, rocking, and/or bobbing, generally follows travel on the sea. The associated symptoms cause considerable distress. The underlying neural mechanisms are unknown, and to date there have been no effective […]
Abstract Head movements in a rotating frame of reference are commonly encountered, but their long term effects on the angular vestibulo-ocular reflex (aVOR) are not well understood. To study this, monkeys were oscillated about a naso-occipital (roll) axis for several hours while rotating about a spatial vertical axis (roll-while-rotating, RWR). This induced oscillations in roll […]
Abstract Tilting the head in roll to or from the upright while rotating at a constant velocity (roll while rotating, RWR) alters the position of the semicircular canals relative to the axis of rotation. This produces vertical and horizontal nystagmus, disorientation, vertigo, and nausea. With recurrent exposure, subjects habituate and can make more head movements […]
