    • Gait Analysis

    Background:

    • Clinical gait analysis is crucial for diagnosing and monitoring various conditions.
    • Existing methods can be expensive, time-consuming, or lack sufficient statistical weighting.
    • There is a need for accessible and efficient gait measurement tools.

    Purpose of the Study:

    • To develop simple, fast, and inexpensive equipment for clinical gait analysis.
    • To provide a versatile tool that can be used independently or as an accessory to other measurement systems.
    • To incorporate essential kinematic parameters like time, distance, and velocity.

    Main Methods:

    • Development of a simple kinematic gait measurement system.
    • Utilized foot-switches for measuring time parameters (step/stride time, swing/stance phase).
