The cover of this issue of Biofeedback shows a depiction of the mythical Sisyphus, condemned for all eternity to push an immense boulder up a hill, only to watch it roll back down the hill. The myth serves as a symbol for all of the medical and nonbiofeedback factors that can hinder biofeedback and neurofeedback treatment. It is our hope that this Special Issue may aid future practitioners to escape the fate of Sisyphus. (Thanks to Shutterstock for this photo).
