App-Based Evaluation of Older People's Fall Risk Using the mHealth App Lindera Mobility Analysis: Exploratory Study.

JMIR aging·2022

This study presents a novel gait analysis system using AI-powered video analysis. It offers valid and repeatable gait parameter measurements comparable to lab systems, making it accessible for widespread use.

Area of Science:

  • Biomechanics
  • Computer Vision
  • Artificial Intelligence

Background:

  • Gait parameter measurement is crucial for healthcare, sports, and rehabilitation.
  • Current high-tech gait analysis systems are often expensive and complex.
  • There is a need for accessible and reliable gait assessment tools.

Purpose of the Study:

  • To develop and validate a novel gait assessment system using convolutional neural networks.
  • To evaluate the system's validity and test-retest repeatability against a gold standard.
  • To enable cost-effective and user-friendly gait analysis.

Main Methods:

  • Utilized convolutional neural networks to extract 3D skeleton joints from monocular frontal-view videos.
  • Compared the novel system's gait parameters (speed, cadence, step length, step time) to the GAITRite walkway system.
