What is OptoGait



OptoGait is a system for optical detection made by a transmitting and a receiving bar. Each one contains 96 LEDs communicating on an infrared (visible) frequency with the same number of LEDs on the opposite bar. Once positioned on the floor or on the treadmill, the system detects the interruptions of the communication between the bars - caused by the patient’s movement - and calculates the duration and position. During the execution of a running, gait or series of jumps test, the contact and flight times can be measured with an accuracy of 1 thousandth of a second and the position of the interrupted LEDs with a space resolution of 1,041 cm. Starting from this basic data, the dedicated software measures in real-time a series of crucial data for the movement analysis. The absence of mechanical moving parts ensures a long life, accuracy and repetition possibilities.

Quantity and Quality Assessment

OptoGait acquires numerical parameters in real-time for gait, running and jump tests that can be viewed immediately. The easy to read report contains all data, and asymmetries between the two legs are highlighted instantly. OptoGait does not only detect the numerical data, but, via small cameras, which can be freely positioned, it allows the user to acquire images of carried out tests, synchronizing them perfectly with detected events. Without the need for any further synchronization between hardware and cameras, the numerous benefits of cross verification of data and images can be fully used. A more detailed video analysis can be had by further utilizing the dedicated utility (angle, distance calculus, graphic tools, etc.).




The modular system

In this configuration, OptoGait allows to carry out :

  • Gait Tests can consist of simple exercises (moving from A to B), but also of more complex ones, such as ‘roundtrip’ or walking backwards. They can be more complex, if needed, adding obstacles (e.g. plastic cones) or actions to be carried out between the various gait phases (sitting down and getting up before coming back, for example) or simultaneously. Dual task and obstructive task walking, can be easily measured here.
     
  • Running Tests, just like gait tests, can be carried out either starting from a stand or running, to analyze the various phases, how the incremental weariness acts on the patient at each round installing the system on a track, measuring the time of a change of direction and the following acceleration, and so on... (see Run Report below)

Thanks to the practical and innovative assembling system using caps, the modular system is assembled in a few minutes and does not require cables to connect the bars or further net adapters. The length goes from a minimum of 2 meters to a maximum of more than 100 meters.
