Technology-Based Gait Analysis

About Gait Analysis

Everyone has a unique gait, and you can easily identify a close friend or family member by their gait alone. Your gait characteristics are influenced by many factors, some of them anatomical and some determined by extrinsic factors. The fundamental metrics of gait change over time, influenced by physical activity, life events, trauma, and other factors both within and beyond your control.

Your body’s structures are designed to move like a well-oiled machine, gliding in harmony without pain or restrictions. When they become injured or misaligned, you develop mechanical issues that cause pain and dysfunction. Functional gait analysis is a tool for identifying mechanical gait deficits and restoring optimal gait via personalized gait retraining.

Tensegrity is the Secret to Pain-Free Mobility

Most people take everyday mobility for granted until an injury occurs or pain sets in. Sometimes pain and reduced mobility seem to arise out of nowhere, with no apparent cause of onset. Regardless of whether your pain is caused by trauma or by something less obvious, tensegrity plays a key role.

Tensegrity refers to tensile integrity – a state where a system of individual components is held together under continuous elastic tension. In the human body, tensegrity is created by the myofascial system, the network of muscles and fascia that work together to produce, control, and guide forces, and to hold the body’s various organs and structures in place during movement.

Tensegrity can be disrupted when myofascial tissues are injured or damaged in some way. When that happens, nerves and blood vessels can become entrapped, preventing them from gliding among other structures and producing pain. At the same time, the elastic tension that governs joint alignment and controls movement becomes compromised, creating motor deficits that undermine mobility and stability.

Factors that disrupt myofascial tensegrity include:

  • Traumatic injury that affects multiple tissue types
  • Overuse injuries from sports, exercise or occupation
  • Old injuries that were never properly rehabilitated
  • Sedentary lifestyle with excessive sitting
  • Obesity that overloads the body’s structures
  • Inadequate hydration that deprives soft tissues of water needed to function
  • Diet high in sugar and carbs that causes myofascial tissue glycation, making it dense and sticky

Many doctors do not understand the crucial role of the myofascial system in preventing pain syndromes, movement disorders, and disease. In fact, most medical doctors have no idea how to correct myofascial dysfunction or even recognize it as a factor. They simply treat pain symptoms with medications and eventually recommend surgery.

At NYDNRehab, we understand that the body’s systems work together as an integrated whole, and that treating pain is not enough to eliminate its source. We use dynamic high-resolution ultrasound to explore the myofascial system in real time. Ultrasound imaging lets us visualize muscles, fascia, nerves and other structures in motion, to identify places where tensegrity has been disrupted.

Once we identify the problem, we use the most advanced therapeutic approaches to restore myofascial integrity and promote tissue healing.

Why Running Gait Analysis Alone is Not Enough to Diagnose Running Injuries

3D gait analysis using advanced technologies can give us valuable insights into biomechanical deficits in running gait, but gait analysis alone cannot give us a clear picture of running injuries. Running gait analysis only gives us data about joint angles, force loads, stride, foot pressure, muscle firing patterns, and other mechanical parameters.

To understand the type and extent of injured tissues, we use high resolution diagnostic ultrasonography in conjunction with gait analysis data. Dynamic real-time ultrasound lets us visualize damaged tissues in motion, to see how they impact and interact with other tissues and structures.

Accurate interpretation of ultrasound images requires extensive experience in clinical examination and an in-depth understanding of running pathologies. With over 20 years of experience in sports medicine, coupled with extensive training and research in musculoskeletal ultrasonography, Dr. Kalika has established himself as a leader in running gait analysis and injury treatment in NYC.

We conduct our gait analysis and ultrasound exam on-site at our clinic. Our cutting-edge technologies and regenerative therapies are designed to accelerate injury healing and correct mechanical gait deficits so you can get back on the road with confidence.

Advanced Technologies for Gait Analysis Make a World of Difference

Pressurized instrumented treadmill

Pressurized treadmills are advanced technological tools equipped with sensors and pressure-sensitive plates. These specialized treadmills allow us to capture quantitative data while you walk or run, which we use to retrain critical gait parameters.

When integrated with our proprietary motion analysis software, data collected from our instrumented treadmill gives us a full picture of your gait characteristics. The information we gather is then analyzed and delivered in a comprehensive report that includes:

0

Normalized force calculations

1

Plantar surface zone analysis

2

Velocity-related gait parameter norms

3

Gait and foot contact patterns

4

Bilateral pressure distribution data

5

Single-step rollover analysis

6

Dynamic and static balance data

7

Much more!

High resolution diagnostic ultrasonography

Most mechanical gait deficits cannot be measured or observed by even the most sophisticated gait analysis system. In many cases, compensation patterns are mistaken for the cause of injury, when in fact they are the result of mechanical issues.

High resolution diagnostic ultrasonography used in conjunction with a personalized clinical assessment lets us detect the primary causes of your gait dysfunction

Dynamic motion ultrasonography

For the first time ever, USONO dynamic ultrasonography lets us observe the joints and muscles in motion as you walk or run. Motion ultrasonography lets us distinguish causative from compensatory factors, a key advantage when treating gait-related injuries. Dynamic muscle ultrasound imaging is especially useful for patients with current injuries, or with a history of prior injuries.

KINEO computerized muscle analysis

The KINEO computerized system objectively analyzes and quantifies muscle function and strength, providing a baseline to monitor your progress, and offering multiple training modalities to improve your gait performance.

ForceFrame Max

 

ForceFrame is a comprehensive system for accurately testing and training isometric strength in various muscle groups throughout the body. Most people – especially physically active people – develop muscle imbalances and compensation patterns over time that reduce movement efficiency.

ForceFrame lets us test individual muscle groups on both sides of the body for strength and symmetry. By testing individual muscle groups isometrically, we eliminate the potential for compensation of weak muscles that could be masked during compound exercise testing.

The results of each test appear as objective data on a screen in real time, helping us to identify and correct muscle imbalances, asymmetrical muscle strength, inefficient muscle firing patterns, and compensation patterns developed from past injuries. We then use that data to create personalized rehab programs, to boost performance and reduce injury risk.

We Treat the Whole Patient, Not Just Your Symptoms

The human body is made up of integrated parts and systems, designed to work in harmony. Today’s modern reductionist approach to healthcare overlooks the integral relationship between structure and function, and medical doctors focus on treating symptoms without exploring the bigger picture.

Most injuries involve multiple structures and tissue types, and pain is only a symptom that signals your brain to protect and heal the damaged tissues. Over time, injuries often stop hurting while damaged structures remain dysfunctional.

At NYDNRehab, we use high resolution diagnostic ultrasound to visualize your injury dynamically, in real time. Ultrasound helps us determine whether structural (anatomical) changes are causing pain and dysfunction, or if dysfunction is causing structural changes. Your ultrasound exam takes place on-site, on your first visit, where we examine multiple areas of the body in a single session – with no waiting for lab results!

Conventional gait analysis is largely observational, and gait can only be analyzed in the sagittal and frontal planes. This approach overlooks critical gait deficits in the transverse plane, where most gait-related injuries occur.

At NYDNRehab, we leverage advanced technologies to precisely measure the mechanical characteristics of your gait in all three planes of motion. By collecting precise data about joint angles, muscle firing patterns, gait cycle characteristics, foot mechanics, load distribution and more, we are able to help you retrain your gait based on your unique quantitative results.

Get Personalized Gait Retraining Based on Quantitative Data

Before we get started on gait correction, we first need to prepare your muscles, joints and connective tissues, to ensure optimal results. We use dynamic high-resolution ultrasound to visualize your body’s structures in motion, to detect mobility issues that are invisible to the naked eye.

Pre-training therapy may involve:

  • Stecco fascial manipulation to treat densified fascia and adhesions
  • Rehabilitation of old injuries
  • Shockwave therapy to treat tendinopathies
  • Joint mobilization to restore functional range of motion
  • Needling therapies to promote joint healing
  • Nerve hydrodissection to normalize neural autonomic input
  • Physical therapy to correct posture, eliminate compensation patterns and restore coordinated muscle activation patterns

Once we optimize your tissues, we can begin to focus on the specific deficits and anomalies detailed in your gait analysis report. Gait retraining involves intrinsic and extrinsic feedback, and we continually measure your progress in comparison to your baseline data.

Who Can Benefit from Gait Analysis?

  • Anyone experiencing joint pain, especially in the low back and lower extremities
  • People who spend a lot of time on their feet
  • Sedentary people who want to get in shape
  • Older adults who want to remain active and avoid falls
  • Novice runners who want to avoid injuries
  • Competitive walkers and runners who want to enhance performance

    Gait Analysis FAQs

    How long does a gait analysis session take?
    You should expect to spend up to 3 hours for your gait analysis session.
    What should I wear for my gait analysis?
    We recommend cool, non-restrictive clothing and athletic shoes. You may want to bring a change of dry clothing to change into after your assessment.
    I have knee pain. Can I still get a gait analysis?
    Yes, knee pain is closely linked to gait mechanics. Our clinicians will conduct a thorough clinical exam prior to your session, in order to customize your gait analysis based on your health profile.
    I had a bad ankle sprain years ago and my gait has never been the same. Is it too late for gait retraining?
    It’s never too late to improve your gait. In addition to gait analysis, we may recommend physical therapy to rehabilitate your old injury and restore functional movement. Our personalized approach to patient care means we treat the whole patient.
    I'm pregnant – should I wait to have a gait analysis?
    Yes, it’s wise to wait until after your “4th trimester,” – at least 3 months postpartum. Pregnancy causes multiple dynamic changes in your body that affect your gait during and beyond childbirth. Your results would not be of much use until after your delivery.

    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.
