Using Sensor Technology to Measure Gait Capacity and Gait Performance in Rehabilitation Inpatients with Neurological Disorders

Simple Explanation

This study uses wearable sensors (IMUs) to measure how well rehabilitation patients with stroke or spinal cord injury walk. It looks at both their best possible walking ability ('gait capacity') and how they actually walk during the day ('gait performance'). The goal is to see if these sensors can give useful information to improve rehabilitation.

Study Duration
Not specified
Participants
22 inpatients (11 strokes, 11 iSCI)
Evidence Level
Observational cohort study

Key Findings

  • 1
    IMUs can accurately measure walking ability in patients with neurological disorders.
  • 2
    Gait capacity, as measured by the sensors, is strongly related to how much patients walk during the day.
  • 3
    Patients' maximum walking speed during the day is similar to their best walking speed during testing, but their average speed is slower.

Research Summary

This study assessed gait capacity and gait performance in rehabilitation inpatients with stroke or iSCI using IMUs. The IMU-based gait algorithm was found to be valid for gait assessment and gait capacity was strongly related to gait performance. Measuring gait performance with IMUs provides valuable additional information about walking activity and spontaneous gait characteristics to inform about functional recovery.

Practical Implications

Improved Monitoring

IMUs can continuously monitor patient's gait, providing a more complete picture of their walking habits.

Personalized Treatment

The data can be used to tailor rehabilitation programs to individual patient needs.

Remote Monitoring Potential

This could lead to at-home monitoring and rehabilitation in the future.

Study Limitations

  • 1
    The wearing time of the IMUs was different between participants due to various personal and/or practical reasons.
  • 2
    possible (slight) deviations from actual therapy time were not registered for reasons of feasibility and privacy.
  • 3
    the algorithm can still be improved.
