Biomechanical Analysis With Real Time Force Plate Technology

biomechanical analysis

At NYDNR we use most advanced force plate technology and 3D video analysis to evaluate biomechanics of an athlete in motion. This cutting edge analysis is of particular importance to runners and athletes who are involved in cutting and jumping movements.

Why athlete needs biomechanical analysis?

Biomechanical analysis can register the forces involved with athletic movement. When these forces exceed normal there is excessive stress to joints, muscles and ligaments. The excessive forces are always the result of poor muscle coordination, improper technique (motor control) and muscular weakness. The in depth biomechanical analysis allows differentiation of these factors and provides proper strategy to reduce injury and improve performance.

What does biomechanical analysis consists of?

The combination of force plate and high-speed cameras with intricate software allows us to register and measure:

  • Ground reaction forces (shock absorption mechanisms);
  • Joint angles;
  • Compensation patterns (whenever there is a deficit in strength or technique the body will initially create compensation pattern in order to allow performance. When compensation patterns are no longer sufficient the body will be prone to injury, performance will be reduced and the athlete will be fatigued. How is biomechanical analysis performed? The runner is performing several movements particular to his sport over the force plate and motion capture area of the lab. These movements are recorded and biomechanical parameters are measured.

How does real time biomechanical analysis helps athlete’s performance and injury prevention?

In order to take the best course of action in a treatment plan for your condition, it’s important to have a keen understanding of the external and internal forces that are at work during movement.

Not only is it important for the staff to understand these forces, it allows you to put your own damage control in place, avoiding further injury or future injuries during movement. Through careful study of biomechanics and motor control, we will be able to help you to

correct your movement patterns. As a result, you can avoid muscle strain, improve shock absorption, avoid overloading your joints and improve performance by becoming more efficient athlete.


In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
