Physical activity
The Barthel index and walking ability were assessed before surgery and
at discharge in the patients with ATAAD. The Barthel index is a widely
used instrument that assesses activities of daily
living.11 The Barthel index score ranges from 0
(completely dependent) to 100 (totally independent), which mean that
lower scores reflect greater nursing dependence.12Walking ability was assessed in terms of the patients being able to walk
without any aid; with assistive devices, such as a walker and crutches;
needed a wheelchair; or were bedridden with all assistance.
Postoperative walking difficulty was defined as patients who needed more
than 30 days to be able to walk a distance of 200 m after surgery or
were unable to walk at discharge.
