Role of sensory information in the control of postural orientation in Parkinson's disease.
Clinical findings and experimental studies both in parkinsonian patients and on animal provide evidence that the control of the axial orientation is markedly impaired in Parkinson's disease (stooped posture, Camptocormia, Pisa syndrome). Nevertheless the postural orientation component in Parkinson's disease has been poorly investigated. One study reports that Parkinsonian patients present a major impairment of the postural orientation component in relation with a proprioceptive impairment. On the basis of these results, the visual dependence observed in Parkinsonian patients is re-defined as an adaptive strategy partly compensating for the impaired proprioception.
