Parkinson Disease Clinical Trial
— PrévSimOfficial title:
Immersive Virtual Reality Using a Head Mounted Display and Modelling Using Machine Learning Algorithms to Assess Risk of Falling in the Elderly and Patients With Parkinson's Disease.
The process of ageing affects at the same time the sensory, cognitive and driving functions.
Furthermore, ageing is often accompanied by pathologies increasing the effects of the
senescence. An ageing subject will have then more difficulties in maintaining balance control
and will have a falling risk with sometimes critical consequences for the quality of life.
The risk of fall is estimated by tests at the same time of current life and with scores of
sensitivity and specificity which must be improved. In a review including 25 studies (2 314
subjects), show a sensitivity of 32 % and a specificity of 73 % on the test "Timed Up and Go"
(TUG) with a threshold at 13.5 seconds.
In addition, the fall occurs in a multifactorial context when a subject interacts with his
environment. It therefore seems essential to test balance control or falling risk of
individuals as close as possible to the situations of daily life. This research, based on the
TUG, will aim to assess the neuro-psycho-motor behavior of subjects in situations close to
daily life using a Virtual Reality (VR) and Human Metrology platform.
The results could ultimately lead to increased sensitivity and specificity in assessing the
risk of falling with a TUG performed in VR, compared to the classic TUG, which is commonly
used by healthcare professionals and thus allow for earlier or more appropriate management of
the subject in preventing the risk of falling. This could allow healthcare professionals to
better understand the risk of falling and thus guide medical recommendations and prescribing,
particularly in terms of appropriate physical activity programs.

Secondary | Psychology analysis 3 | Measurement of the coping strategies (Ways of Coping Checklist from Folkman & Lazarus with scores from 1 to 5 for the remembered stress situation subjective evaluation, a score from 10 to 40 for the Problem item, a score from 9 to 36 for the Emotion item and a score from 8 to 32 for the encourgament item). | Baseline | |
Secondary | Automated learning and falling risk estimation | Supervised learning with Support Vector Machine, Decision tree, Linear discriminant. Using machine learning algorithms is not a measurement but data processing compiling all the data from measurement and comparing them to the number of fall during the year follow up. Machine learning algorithms will learn from these data to classify any new participant into a profile "with a low risk of fall", "with a high risk of fall" or "without a risk of fall". |
