Why Running Services at NYDNRehab are Superior to Average Running Clinics

The clinic at NYDNRehab is one of few private clinics in the United States to employ sophisticated 3D gait analysis technology to diagnose and treat runners. Our quantitative approach takes the guesswork out of gait analysis and gives us precise metrics to gauge your performance.

Our running services encompass more than gait analysis, but your 3D running gait analysis lays the foundation for your retraining program. Unlike most clinics that use primitive 2D analysis tools to make an observational and subjective assessment, we use the most advanced technologies available to conduct an objective analysis based on hard data. We turn that data into useful information that helps patients correct and restore optimal gait patterns.

At NYDNRehab, our gait analysis package includes a combination of technologies and methodologies unavailable elsewhere in NYC, such as:

  • 3D gait analysis equipment and software to measure gait in three dimensions

  • Real-time running feedback retraining

  • Instrumented force treadmill to assess dynamic center of pressure

  • Surface EMG (SEMG) to evaluate muscle activation patterns

  • Dual force plate technology to monitor bilateral ground reaction forces

  • Diagnostic musculoskeletal ultrasonography

But we don’t stop there. We use our cutting-edge equipment to learn everything we can about your running performance. Our assessment package includes:

  • Artificial intelligence (AI) computerized muscle strength assessment

  • Sonoelastography assessment for muscle stiffness

  • Balance assessment using C.A.R.E.N, our computer-assisted rehabilitation environment

  • C.A.R.E.N stability assessment

Our Gait Retraining Treatment Options

Once we have your assessment results in hand, we are ready to move forward with a personalized training program tailored just for you. We never take a one-size-fits-all approach to running physical therapy. Our personalized one-on-one approach ensures that you get the exact treatment you need to perfect your running performance.

Our treatment options include


Specialized physical therapy for runners, to enhance your strength, power and range of motion in muscles and joints throughout your body.


Chiropractic care to realign joints and promote smooth pathways for nerve gliding.


DD Robotech artificial intelligence (AI) powered robotic training equipment for real-time feedback retraining.


Ultrasound guided dry needling to target deep tissue trigger points.


Regenerative therapies that accelerate healing and reduce pain and inflammation, including focused, defocused and radial shockwave therapy (ESWT), and extracorporeal magneto transduction therapy ( EMTT).


Ultrasound guided injections such as platelet-rich plasma (PRP) and Prolotherapy, to speed up healing in joints and connective tissues.


Kineo Intelligent Load system for AI muscle testing and retraining.


C.A.R.E.N, our computer-assisted rehabilitation environment for feedback, balance and stability training.


Blood flow restriction training for restoring muscle strength without overloading injured joints and tissues.

Running Injury Prevention

Running Injury Prevention

An ounce of prevention is worth a pound of cure, and we prefer to see you before you get injured, so you can run pain-free for years to come. The best way to prevent running injuries is to detect anomalies in your running gait that cannot be seen by the naked eye.

Average running clinics focus on improving the gait cycle using observational and subjective assessments.

At NYDNRehab we utilize the most advanced research-grade technologies available to measure stride parameters, biomechanics, ground reaction forces, strength, postural stability and balance. We check you out from head to toe, to identify any weaknesses or deficits that can potentially lead to injury.

Training for a Marathon, Triathlon or Ironman?

Long races are the ultimate challenge for any runner. They force you to dig down deep to find inner strength you didn’t know you had.

The sports medicine specialists at NYDNRehab have over 15 years of experience in preparing novice, recreational and elite runners, and those recovering from injuries, to successfully complete long races without injury.

There is more to training for a race than just running. You need to balance running with recovery, nutrition, sleep and hydration. We develop personalized training programs based on your assessment results. Our technological tools enable us to establish a baseline and track your progress objectively, and adjust your retraining program accordingly.

Cookie-cutter training protocols can be found online, but they do not take into account your unique profile. A training program for a novice runner should be far different from that of an elite athlete. If you want to successfully cross the finish line in your best time, without pain or injury, a personalized training program is essential.

Post-Running Recovery

Recovery is a vital component of any training program. Failure to allow your body to fully recover is a sure way to develop overuse injuries that can take months to heal. But you don’t have to recover on your own.

The running specialists at NYDNRehab use a variety of technologies to help your body heal damaged and overworked tissues. These evidence-based tools accelerate the recovery process so you can get back on the road as soon as possible.

Our recovery toolbox includes

NormaTec Compression system

NormaTec Compression system to massage your limbs, mobilize built-up fluid and speed recovery.

Zimmer emField Pro high intensity PEMF (Pulsed ElectroMagnetic Field) device to stimulate fast healing of micro tears in muscles and connective tissues.

Extracorporeal Magneto Transduction therapy (EMTT), to deliver electromagnetic fields that reduce pain and stimulate cell repair in cartilage and menisci.

Extracorporeal shock wave therapy (ESWT), to deliver high-frequency energy waves that stimulate the repair of damaged and painful tissues. Shockwave therapy promotes blood vessel formation and increases blood flow for greater oxygen and nutrient delivery.


Ultrasound guided dry needling, to release deep tissue trigger points that often form in muscles, fascia and connective tissues after intense training.

    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.
