Spinal deformities are common abnormalities of posture observed in Duchenne Muscular Dystrophy (DMD). Spinal alignment is the result of the integrity of different variables, ranging from normal vertebral development to balance and symmetry of tone and strength, normal control by central pathways and integrity of the sensory feedback. Any disturbance altering one or more of these variables increases the risk for developing abnormal postures. Scoliosis is a frequent complication (68-90%) of DMD. Although the risk of developing scoliosis is higher in non-ambulant DMD patients, scoliosis and kyphosis can be found occasionally in ambulant patients. In DMD patients the onset and the evolution of the abnormal postures are related to the onset and the progression of weakness. This review discusses the factors affecting posture in DMD, especially in relation to scoliosis and gives an overview of general guidelines on the diagnostic approach and some management issues related to DMD.
