TO THE EDITOR:
Cadmus-Bertram and colleagues' study (1) suggests that some wrist-worn activity trackers perform similarly to electrocardiography at rest but that none was as accurate as electrocardiography during moderate exercise (1). We agree that additional research is needed before these monitoring devices can be deemed useful for clinical advice or trials. In fact, most consumers are probably unaware of potential inaccuracies and may experience health risks related to under- or overexercise. On the basis of our recent experiment for an Advanced Placement high school research project (Singh J. Unpublished data.), we would like to highlight the additional need for ...
