This article constitutes a description of a clinical entity that has been o
bserved and that we have described in French literature for over 10 years.
This syndrome has been named 'la Regression Psychomotrice' in the french la
nguage and is termed here 'psychomotor desadaptation syndrome' (PDS). Postu
ral impairments, neurological signs and psychological features have been fo
und to be associated with PDS. Postural and neurological disorders were cha
racterized by retropulsion, muscle tone modification, and the loss of react
ive and protective postural reactions. Psychological features consisted of
slowness of cognitive processing, often associated with anxiety and a fear
of falling. PDS may be considered as a functional disorder, and clinicians
must identify not only predisposing factors, but also etiological ones. The
medical treatment of these factors and specific readaptation approaches mu
st be associated with the management of PDS. PDS appears to be a reversible
syndrome if a multidisciplinary approach and early management are undertak
