Gait Assessment Via Telephone Application

March 21, 2025 updated by: Aysenur Erekdag, Istanbul University - Cerrahpasa

Validity and Reliability of a Smartphone Application for Gait Assessment

The evaluation of human gait is a crucial component of the clinical assessment and decision-making process. The gold standard in gait analysis is computerized gait analysis, which allows for three-dimensional digital data acquisition through computers (3D Computerized Gait Analysis). However, this technology is not readily accessible in routine analyses, as it proves to be a time-consuming and expensive endeavor in terms of infrastructure and human resources. The utilization of smartphones in clinical applications is on the rise, facilitated by the increasing accessibility of low-cost or free "applications," thereby addressing the limitations associated with traditional gait analysis methods. The Gait-Analyzer application is among the mentioned applications. However, in the literature, no evidence has been found regarding the validity and reliability of Gait-Analyzer application compared to the gold standard 3D computerized gait analysis systems within the context of gait analyses.

The aim of this study is to comparatively examine the effectiveness of the Gait-Analyzer smartphone application with established 3D Computerized Gait Analysis systems, which have proven validity and reliability in gait analyses. Through this research, the study intends to elucidate the validity and reliability of spatiotemporal parameters of walking within the Gait-Analyzer smartphone application.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
3D Computerized Gait Analysis
The gait analysis will be conducted through 3D computerized gait analysis.
Other: Gait analysis
It will be carried out on a 10-meter flat surface, with the participant walking at normal walking speed.
Gait-Analyzer
The gait analysis will be performed using a smartphone application called Gait-Analyzer.
Other: Gait analysis
It will be carried out on a 10-meter flat surface, with the participant walking at normal walking speed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Three-Dimensional Computerized Gait Analysis
Time Frame: change from baseline at first week
Reflective markers are placed on specific anatomical points to record varying joint angles throughout the walking cycle. Patients walk a distance of 9-10 meters, capturing records of their walking patterns and speed in everyday life, either barefoot or using assistive walking devices.
change from baseline at first week
Gait-Analyzer
Time Frame: change from baseline at first week
Gait-Analyzer is a mobile application for smartphones capable of real-time analysis of walking parameters. Using a smartphone with an Android processor and the "Gait Analyzer" application, directly attached to the participants' lumbar spine (nearest to L5) with a waist belt, participants will be instructed to complete 6 laps (12 forward and backward walks) on a 10-meter walking path.
