3D Motion Analysis

About 3D Motion Analysis

Most people take movement for granted until something goes wrong. Even then, many people accept reduced mobility as a natural part of aging. But the human body is designed to move in fluid and coordinated patterns that conserve energy, generate power, and optimize mechanical potential.

When movement is impaired by injury or overuse, a 3D motion analysis can help us accurately identify factors that impede movement and cause pain and dysfunction. Once we have a clear picture of the underlying causes of impaired movement, we are able to create a personalized treatment plan based on your unique patient profile.

Our 3D motion analysis system was designed by Dr. Kalika and implemented by STT.

Our motion analysis system consists of:

  • Ten OptiTrack motion capture cameras
  • Dual force plates
  • Surface electromyography (SEMG)
  • USono portable device

USono technology allows us to visualize your body in motion via diagnostic ultrasound, and sync it with data from our cutting-edge motion analysis technology. Our 3D system is based on the latest evidence-based research on motion analysis.

How it Works:

  • Electronic sensors are attached at strategic sites on your body.
  • The patient stands with one foot on each force plate, surrounded by motion capture cameras.
  • Specific movements are performed, and the sensors transmit real-time information to our proprietary motion capture software.
  • The information is synchronized and a report is generated.
  • The doctor interprets the data and uses it to create a personalized treatment plan.

Our 3D motion analysis technology lets us accurately detect motor deficits that contribute to pain and reduced mobility. Prior to beginning physical therapy, we use our regenerative technologies to pre-treat damaged tissues, to stimulate and accelerate the healing process. Dr. Kalika is trained and certified in a broad range of rehabilitative treatment modalities. His ongoing commitment to personal growth and continuing education, along with his personalized approach to patient care, set NYDNRehab apart as the premier clinic for biomechanical analysis and rehabilitative therapy in NYC.

Proprietary Software and Advanced Technologies Make Our Motion Analysis Lab Unique

The motion analysis lab at NYDNRehab features some of the most advanced technologies for biomechanical analysis currently available. Such technologies are rarely found in a private clinical setting.

Our motion analysis lab is ever-evolving as new research and technologies emerge. Our data-driven approach gives us measurable markers that ensure your treatment delivers the desired results. We designed our motion analysis lab based on SEBT research. SEBT is considered the gold standard for motion analysis protocols.

3D motion analysis is a full-body approach that registers motion in the lower and upper body. It provides data about movement in the following parameters:

  • Kinematics measures joint angles during specific movement patterns and provides information about the timing of movement between right and left sides of the body.
  • Kinetics provides data generated from dual force plates about ground reaction forces and weight distribution.
  • Surface electromyography (SEMG) collects data from multiple strategically placed sensors to provide information about muscle firing patterns and motor recruitment. It tells us whether muscles are underactive or hyperactive, how they impact joint alignment and function, and how the muscles respond to ground reaction forces.
  • Motion ultrasonography is a new innovation made possible by an adapter that allows us to sync real-time imaging with motion analysis data. It allows us to look at single or multiple muscles in motion, to see how they interact with adjacent structures. Motion ultrasonography lets us distinguish causative from compensatory factors, for well-informed decision making about the most appropriate treatment protocol.

Who Can Benefit from 3D Motion
Analysis?

3D Motion Analysis is appropriate for:

  • Patients with complex motor problems whose clinical examination or radiology results failed to provide an accurate diagnosis.
  • Patients suffering from joint pain in their ankles, knees, hips and low back.
  • Patients recovering from ACL injuries.
  • Athletes who play sports that require cutting and pivoting.
  • Athletes who want to optimize their performance and reduce their risk of injury.
  • Injured athletes who want to return to sports after injury rehab.
  • Anyone who wants to enhance and optimize mobility for a better quality of life.

Humans are born with innate developmental software that governs their progression from helpless infant to active toddler. As human babies overcome gravity and master upright movement, they are able to run, jump and acquire new skills with ease.

Over time, certain factors may come into play that disrupt functional movement patterns, such as injuries, poor posture, environmental toxins, and other threats. 3D motion analysis can help people with impaired movement to identify and rehabilitate dysfunctional patterns and restore functional movement.

Biomechanical Analysis as a Diagnostic Tool

Much like the engine of your car, the human body is more than the sum of its parts — it is a complex organism made up of integrated and interdependent systems that all play a role in human movement. Isolating a single part of the body or zeroing in on symptoms alone to diagnose a patient’s condition inevitably leads to mistreatment or under treatment, often spinning a web of complexities that worsen the patient’s condition.

3D motion analysis lets us look beneath the hood, to view your body’s systems in motion and observe how they interact. It helps us determine whether your symptoms are causative or compensatory, and sheds light on complex problems that involve multiple structures.

A patient presents with prior ankle trauma that appears stable based on clinical testing and diagnostic ultrasonography. However, those diagnostic tools cannot really tell us the whole story. There may be underlying sensory-motor ankle instability that can alter movement along the entire kinetic chain, affecting the knee, hip, pelvis and lumbar spine.

In other words, prior trauma can create compensation patterns that are invisible to the naked eye. They can cause suboptimal and uncoordinated muscle firing patterns that affect other joints, creating a false diagnosis of ankle stability. 3D motion analysis helps us unravel the factors that cause pain and reduce mobility and stability.

    3D Motion Analysis FAQs

    Do I need a doctor’s prescription for a 3D motion analysis?
    No, a doctor’s prescription is not required. We will thoroughly screen you for any health issues or contraindications prior to beginning your biomechanical analysis.
    I have had chronic low back pain for over a year. My doctor prescribed an MRI, but they couldn’t find anything wrong. Can a motion analysis help?
    Back pain is often caused by mechanical issues that arise far from the locus of pain. A 3D motion analysis gives us insights that cannot be obtained from MRI. Once we identify motor deficits that contribute to your back pain, we will be able to take corrective measures that eliminate the true source of pain.
    My athletic injury happened over 10 years ago, and I’m living with the repercussions. Is it too late for a biomechanical analysis?
    It is never too late to rehabilitate an old injury, with the goal of eliminating pain and restoring mobility. In fact, neglecting to do so can set you on a path of long-term disability as you age.
    I had ACL reconstructive surgery after a basketball injury. Can a performance analysis help me get back in the game?
    While most athletes have physical therapy after ACLR surgery, neuromuscular pathways are often not fully rehabilitated. Once we get a look at your biomechanical parameters, we will be able to zero in on motor deficits and compensation patterns, to optimize motor recruitment and reduce your risk of re-injury.
    I am a competitive runner. Can a 3D motion analysis help improve my performance?
    While the short answer is yes, you may benefit more from a 3D running gait analysis and gait retraining with intrinsic/extrinsic feedback.

    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.
