Hagedorn (2014) has highlighted the infection risks in biofeedback and neurofeedback practice and identified broad strategies for mitigating infection risk. In the age of Clostridum difficile, Methicillin-resistant Staphylococcus aureus, and human immunodeficiency virus, infection risk cannot be ignored in any health discipline that attaches sensors to patients' skin in most treatments. The present article discusses specific guidelines for care and hygiene of biofeedback and neurofeedback instruments, encoders, cables, and sensors. Attention to practice standards can greatly reduce the risk to practitioner and client alike.
