Running Gait and Sports Injury Clinic

NYDNR’s running and sports injury clinic was developed to provide a diagnostic service to injured runners and other athletes. In order to understand the cause of running injuries, sophisticated and precise biomechanical analysis must be conducted. This evaluation includes a computerized gait analysis that utilizes our state of the art motion analysis laboratory, with a specialized treadmill, a 3D video analysis system with special software, a surface electromyography system, and ground reaction force plates.

What Is the Procedure?

An initial evaluation is performed to determine how the athlete’s unique body structure may be influencing their movement. This comprehensive evaluation includes a detailed injury history, assessing shoes and abnormal wear patterns, and assessing bodily structure and alignment, with a focus on the trunk and lower extremities.

During gait analysis, movement patterns are monitored as the athlete runs a course constructed the lab. A 3D camera motion analysis system gathers data and delivers it to a computer, where joint angles and speed of motion are calculated from this information.

As part of the analysis, a force plate located at the center of the runway measures the runner’s ground reaction forces, providing information about balance and weight distribution, and revealing where excessive loading is occurring. Videotaping is done from the front, rear and side to provide a visual assessment of the runner. Muscular activity is recorded with a surface electromyography system.

Interpretation of Gait Analysis

Gait analysis gives us quantitative and qualitative data that can be integrated with results from the structural assessment, biomechanical analysis, and injury history to determine the best course of treatment for the individual athlete.

From this analysis, recommendations are typically made in the following areas:

  • Orthotics or braces to control and facilitate normal movement
  • Footwear recommendations and shoe modifications to optimize gait patterns
  • Therapeutic intervention to strengthen and improve the flexibility of muscles that may be contributing to abnormal gait patterns
  • Correction of movement mechanics that may be contributing to abnormal gait

Should You Invest In A Gait Analysis?


Ibra morales thirty time nyc marathon participant

Dr. Kalika, I just want to thank you and your incredible team for helping me recover and run the NYC marathon for the 30th time this coming Nov. 7th. As you can see in the attached poster, the NYRRC had selected me as one of the runners in this year’s marketing campaign. When I got injured in June and visited various Dr. with no improvement , I was referred to you. When I came in, I could hardly walk, never mind running. Now I’m ready to tackle the NYC marathon for the 30th time! Thanks to Nick, Gregg, Sunny and Anna!! Your team is great and thanks to “your incredible personal attention” to my injuries! I’m ready!!

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.
