Low back syndromes in dancers are intimately related to flaws in the dance technique, especially postural faults and incorrect movements into hyperextension of the hip. The pathology produced by the technical faults is multiplied in those dancers whose physiques are not ideally suited to withstand the stresses of classical training. A thorough understanding of the biomechanical aspects of the dance technique is essential to prevent and rehabilitate these low back syndromes in dancers. J Orthop Sports Phys They 1986;7(4):180-191.
