  <body>
    <p>In “Design and Evaluation of User-Centered Exergames for Patients With Multiple Sclerosis: Multilevel Usability and Feasibility Studies” (JMIR Serious Games 2021;9(2):e22826) the authors noted two errors.</p>

    <p>In the originally published manuscript, the images displayed as Figures 9-13 were associated with the incorrect figure numbers. Figure captions and numbering were otherwise unaffected. The following changes have been made in the corrected version of the manuscript:</p>


<list list-type="bullet">
	<list-item>
		<p>The image displayed as Figure 9 has been corrected to appear as Figure 10.</p>
	</list-item>
	<list-item>
		<p>The image displayed as Figure 10 has been corrected to appear as Figure 11.</p>
	</list-item>
		<list-item>
		<p>The image displayed as Figure 11 has been corrected to appear as Figure 9.</p>
	</list-item>
		<list-item>
		<p>The image displayed as Figure 12 has been corrected to appear as Figure 13.</p>
	</list-item>
		<list-item>
		<p>The image displayed as Figure 13 has been corrected to appear as Figure 12.</p>
	</list-item>
</list>

   
    <p>In addition, under the section “Qualitative Data,” the following sentence appeared in the originally published version:</p>
    <disp-quote>
      <p>In summary, all participants reported an enjoyable, motivating, varied, and fun experience with the exergames, which was a completely new thing for most of them (Figures 9, 11, and 12).</p>
    </disp-quote>
    <p>This has been corrected as follows to properly format in-text references to figures according to journal style:</p>
 
        <disp-quote> <p> In summary, all participants reported an enjoyable, motivating, varied, and fun experience with the exergames, which was a completely new thing for most of them (Figure 9, Figure 11, and Figure 12).</p></disp-quote>

    <p>The correction will appear in the online version of the paper on the JMIR Publications website on May 12, 2021, 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>
