• Moseley GL, Flor H. Targeting cortical representations in the treatment of chronic pain: a review. Neurorehabil. Neural Repair. 2012;26(6):646–52.

• Lewis JS, Kersten P, McPherson KM, et al. Wherever is my arm? Impaired upper limb position accuracy in complex regional pain syndrome. Pain. 2010;149(3):463–9. Available at:
