Mirror movements are involuntary movements that accompany the voluntary movement of the contralateral homologous body part. Etiologically, these movements could be broadly divided into two main groups: congenital and acquired mirror movements. The pathogenesis of mirror movements is different in both these groups. Minor physiological mirroring is seen in normal healthy individuals and can occur during normal childhood development, whereas apparent mirroring in adults can be present in many movement disorders. Interestingly in these neurological disorders, mirror movements are seen in a particular limb at a particular time course of the disease. This may help in making an early diagnosis and could help in the differentiation between the various movement disorders. The coordinative behavior of the central nervous system is an inherent need for an adult to work with both hands, interruption of which makes a person unable to do the coordinated task with hands. Examination of mirror movements also contributes to our understanding of movement disorders, their clinical clues, and associated pathophysiology. |
