    <p>In “Measuring Physical Functioning Using Wearable Sensors in Parkinson Disease and Chronic Obstructive Pulmonary Disease (the Accuracy of Digital Assessment of Performance Trial Study): Protocol for a Prospective Observational Study” (JMIR Res Protoc 2024 May 7:13:e55452) the authors noticed one error:</p>
    <p>The last author's name was listed as:</p>
    <disp-quote>
      <p>Bastiaan Bloem</p>
    </disp-quote>
    <p>This has been changed to the following:</p>
    <disp-quote>
      <p>Bastiaan R Bloem</p>
    </disp-quote>
    <p>The correction will appear in the online version of the paper on the JMIR Publications website on December 09, 2024, together with the publication of this correction notice. Because this was made after submission to PubMed, PubMed Central, and other full-text repositories, the corrected article has also been resubmitted to those repositories. </p>
