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.

Dr. Lev Kalika is a holistic practitioner of integrative health care and Clinical Director at NYDNRehab in Manhattan NYC. He has dedicated his life’s work to finding innovative solutions to human movement disorders and pain syndromes, and has multiple scientific publications to his credit.
Dr. Kalika has nearly 20 years of experience in gait analysis interpretation, earning him multiple national awards in the field of running and sports medicine. He studied gait analysis directly under Christopher Powers and Irene Davis, two of the world’s most eminent leaders in running research.
With 25 years of experience in diagnostic ultrasonography, Dr. Kalika is able to apply his skills to visualizing muscles, tendons, ligaments and fascia, to differentiate compensation patterns from the true causes of gait deficits and injuries.
The biomechanical analysis lab at NYDNRehab features some of the most advanced technologies currently available for quantifying and analyzing human movement. NYDNRehab has been named multiple times by Runner’s World magazine as NYC’s go-to clinic for high-tech gait analysis.
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:
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.
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.
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:
Normalized force calculations
Plantar surface zone analysis
Velocity-related gait parameter norms
Gait and foot contact patterns
Bilateral pressure distribution data
Single-step rollover analysis
Dynamic and static balance data
Much more!
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
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.
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 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.
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.

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.
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.
