Abstract
Body perception disturbances in Complex Regional Pain Syndrome (CRPS) comprise both alterations in the sensorimotor representation of the limb (changes in the perception of shape, size, and proprioceptive representation) and in the conscious perception of the limb (negative emotions, aversion to appearance or the feeling of disownership). They are more frequent and more significant in CRPS. At present, the pathophysiological hypotheses have not been elucidated. The Bath CRPS Body Perception Disturbance Scale provides a wealth of qualitative and quantitative information. Its originality lies in the drawing of a mental image of the affected limb, which requires cooperation between the patient and the assessor. Therapeutic treatments are still underdeveloped. They involve strategies aimed at modifying, stimulating, and training multisensory perceptions.
