Usability of the Smart Hallway System in Clinical Setting

As part of the regular clinical examination, the patients walk straight through a 7m long walkway, turn, and come back while data is collected with the Smart Hallway system. They start walking one meter outside the capture volume. The procedure is repeated five times to provide a sufficient number of walking cycles. Three-dimensional temporospatial gait features (position, joint angles, velocities, accelerations) are extracted from the acquired data.

Data on falls during rehabilitation is routinely collected and entered in the hospital information system (HIS). It will be transferred from the HIS to the study database upon the patient's discharge.

The World Health Organisation Disability Assessment Schedule (WHODAS II) is a generic patient-reported outcome measure of disability that has been translated into Slovenian. It covers six life domains. The scores range from 0 to 100; higher score indicates more disability (i.e., worse outcome).

The Activity Specific Balance Confidence Scale (ABC) is a pathology-specific patient-reported outcome measure of balance that has been translated and validated in Slovenian. The scores range from 0 to 100; higher score indicates more confidence (i.e., better outcome).

The Hospital Anxiety and Depression Scale (HADS) is a patient-reported outcome measure that is used for assessing depression, which has been translated and validated in Slovenian. The scales comprises 14 items, 7 for anxiety and 7 for depression, all scored from 0 to 3, so the score range is from 0 to 21 for either anxiety or depression. Higher score means more pronounced anxiety and depression (i.e., worse outcome).

The Six-minute Walk Test (6MWT) is a standard test for assessing walking speed over a long distance with good and well-known metric characteristics. Longer walked distance means higher walking speed (i.e., better outcome).
