Introduction: Mal de Debarquement Syndrome (MdDS) is a condition characterized by a perception of self-motion in the absence of a stimulus, with two onset types: Motion-Triggered and Spontaneous. Currently, the pathophysiology is unknown and consequently, the therapeutic options are limited. One proposed treatment protocol, developed by Dai and colleagues is based on optokinetic stimulation, which aims to re-adapt the vestibular ocular reflex. This study aimed to reproduce the treatment protocol developed by Dai and colleagues and to assess if a placebo effect is present in the treatment protocol and lastly, aimed to further investigate the treatment on MdDS patient outcomes.
Method: Twenty-five MdDS patients (13 Motion-Triggered and 12 Spontaneous) were exposed to 5 consecutive days of optokinetic treatment (consisting of exposure to optokinetic stimuli with head movements). Eleven of these 25 patients were also exposed to 2 days of a sham treatment prior to the OKN treatment. Posturography measurements and reported symptoms [e.g., using the visual analog scale (VAS)] of patients were assessed throughout the treatment. Posturography data of the patients was compared with the data of 20 healthy controls.
Results: No placebo effect was recorded with any changes in postural data and VAS scale. After the optokinetic treatment, a significant improvement in postural control was observed in 48% of patients, of whom 70% were of the Motion-Triggered subtype (p-values: Area under the Curve—Anterior Posterior < 0.001; Area under the Curve—Medio Lateral p < 0.001, Confidence Ellipse Area (CEA) < 0.001, Velocity < 0.001).
Conclusion: The protocol was effective in approximately half of the MdDS patients that took part in the study, with no placebo effect recorded. The Motion-Triggered group responded better to treatment than the Spontaneous group. In addition to this, this study indicates that the greatest postural changes occur within the first 3 days of treatment, suggesting that a shorter protocol is possible. Overall, these findings support what was previously observed in Dai’s studies, that optokinetic stimulation can reduce and ease self-motion perception in those with MdDS. Thus, validating the reproducibility of this protocol, suggesting that a consistent and uncomplicated implementation across treatment centers is possible.
IMAGINE LIVING LIFE WITHOUT BALANCE.
Close your eyes and stand on one foot. It’s hard right? Now imagine having that same disoriented feeling on two feet, and with your eyes open. Balance is something most of us take for granted. It’s automatically hardwired into our bodies at birth, evolving and adapting as we grow and age. While basic balance is innate, some of us are able to perfect or even master our balance through exercise and practice. We don’t often think about our balance—until of course, we lose it.
While most people may not be familiar with the word “vestibular”—relating to your inner ear, brain, and sense of balance—many of us have likely experienced the awkward or sometimes scary feeling when we momentarily lose our balance. Maybe it’s taking a wrong step or getting motion sickness aboard a jostling boat. Or that nauseating head-spinning sensation after one too many alcoholic beverages.
Eventually our balance comes back and life moves on.
This is not the case for the over 69 million Americans who suffer from the mostly invisible and frequently debilitating symptoms of chronic imbalance association with a vestibular disorder.
Whether it comes on gradually over time or all of the sudden, bouts of dizziness, vertigo, and nausea can make many of life’s more routine tasks virtually intolerable. Just try getting a good night’s sleep with a high-pitched ringing in your ear. Or try to focus on something as everything around you appear to be spinning.
For those living with a vestibular condition, everyday life becomes a progressively challenging obstacle course to navigate.
That is why VeDA pioneered Balance Awareness Week in 1997: to be an opportunity each year to come together and shine a light on these otherwise invisible balance disorders. If we’re all more aware, then we can better understand and be empathetic to those who need our support the most—our family, friends, co-workers, and neighbours. While many of these balance disorders are incurable, faster and more accurate diagnosis, along with effective coping strategies can greatly improve quality of life.
Join Balance Awareness Week, and together we can pave the way toward restoring a life rebalanced.
- Balance Awareness Week (BAW) is 9/16-9/22
- 30% of the U.S. population has transient or constant issues with balance
- The goal of BAW is to educate the public about vestibular disorders so people with undiagnosed dizziness and imbalance can get the help they need, reducing healthcare costs and improving quality of life.
Every other year Professor Sharpe travels overseas to Barany.
However, there have been many other conferences, seminars and gatherings of which she has attended as an invited guest or participant. For example, the French Society of Vestibular Physiotherapy (SFKV) is a scientific society that is currently predominantly made up of physiotherapists who specialise in the rehabilitation of people experiencing neurosensory balance disorders and dizziness.
So, as the images show, from dinner at The Hague in Amsterdam with Frank and PollyAnne for the Vestibular master class in 2016, to SFKV in 2015 and the Barany Meeting 2016 in Seoul, remaining at the forefront of your specialised field takes time, effort, dedication, and passion.
It’s worth it for our personal development ie to immerse ourselves into other cultures, however most importantly we get to meet and be experts and influencers in our field, we learn and develop new knowledge and finally, gain new perspectives.
We encourage you to consider Adelaide, South Australia a destination of choice when courses are offered here. They are all great experiences. The 2020 Barany meeting will be held in Madrid Spain.
