Outcome Measures

Primary Outcomes (1)

  • Assessment of the accuracy of the classification algorithm for the detection of movements parameters

    During both study phases, patient movement is recorded using two sensors on the non-affected/dominant ankle side. Lower extremities are filmed for precise data annotation. In phase 1 (model improvement), patients undergo a test battery to improve the accuracy of the algorithm developed in the pilot study for motion and activity detection. The test battery contains a fixed sequence of movements, including lying, sitting, standing, walking and stair climbing. In phase 2 (model validation), a less restrictive test battery is used to validate algorithm accuracy. Patients perform movements like lying, sitting, standing, walking, and stair climbing for up to 15 minutes. Sequence and duration are not predefined. Algorithm accuracy is assessed via a multi-class confusion matrix. Rows show actual classes, columns show predicted classes. The diagonal contains observations where predicted matches actual (true positive). Accuracy \[%\]= (Sum of diagonal elements/Total observations)\*100.

    during hospitalization (up to 1 hour)

Secondary Outcomes (2)

  • Comparison of the accuracy of the algorithm with and without the use of altimeter data

    during hospitalization (up to 1 hour)

  • Assessment of the comfort level associated with wearing the sensors

    during hospitalization (up to 10 min)

Sampling MethodProbability Sample
Study Population

Acute hospitalized patients are continuously recruited by the project management team within the context of daily clinical practice from both medical and surgical wards at the University Hospital Basel. Recruitment takes place as soon as possible after admission to the hospital.

You may qualify if:

  • patient must have been able to walk before hospitalisation (with or without aids)
  • patient must be cognitively able to follow instructions (if a cognitive assessment has been carried out, this cut-off value counts, if no assessment is available, no cognitive impairment is assumed)
  • ≥ 18 years
  • signed informed consent

You may not qualify if:

  • patient unable to move prior to hospital admission
  • discharge on the same day
  • inability or contraindications to participate in the study or to follow the study procedures, e.g. due to certain neurological disorders (such as Parkinsonism, hemiplegia, severe Multiple Sclerosis), speech problems, mental disorders, or cognitive impairments
  • isolated patient (unable to complete the test battery completely)
