Traditional methods like polysomnography or questionnaires are resource\u2010intensive and may not capture sleep in natural settings. We explored whether widely available consumer\u2010grade smartwatches offer a feasible way to assess sleep quality in this population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The Electronic Monitoring of Disease Activity in patients with CIDP (EMDA\u2010CIDP) study was a prospective observational study conducted from January 2023 to July 2024 at the University Hospitals of D\u00fcsseldorf and M\u00fcnster. 46 patients had nighttime sleep recorded for 6 months via smartwatch.
