is a cerebrovascular accident (CVA) that causes an interruption of blood supply to the brain, resulting in damage to the nerve cells.

There are two types of stroke:
  • Ischemic CVAoccurs when a blood vessel that supplies blood to the brain becomes obstructed by a blood clot. Nearly 90% of strokes are ischemic CVAs.
  • Hemorrhagic CVAoccurs when an artery in the brain leaks blood or ruptures. The leaked blood places pressure on the brain cells, causing damage to the cells. There are two types of hemorrhagic stroke:
  1. 1Intracerebral hemorrhage – the most common type – occurs when an artery bursts in the brain and blood floods the surrounding tissues.
  2. 2Subarachnoid hemorrhage – is caused by bleeding between the brain itself and the thin tissues that surround it.

Risk Factors and Signs of Stroke

Risk Factors and Signs of Stroke

Stroke (cerebrovascular disease) can occur at any age, although 75% of CVAs occur in people over age 65. CVAs are a leading cause of serious long term disability in the US, with about 800,000 strokes occurring each year. Over 7 million stroke survivors live in the United States, and two-thirds of them are disabled. Stroke is the fifth leading cause of death in the USA, with 147,810 incidents in 2020, according to the Centers for Disease Control and Prevention (CDC).

The number one risk factor for stroke is high blood pressure, followed by atrial fibrillation and cigarette smoking. Weight control, smoking cessation, healthy diet and exercise are all effective strateges for avoiding CVAs.

The most common signs of stroke

Signs of stroke vary, depending on the type, location and severity. According to the American Heart Association, the most common signs of stroke include:

Sudden numbness or weakness of the face, arm, or leg, usually on one side of the body.
Sudden confusion, and difficulty speaking or understanding speech.
Sudden difficulty seeing in one or both eyes.
Sudden dizziness, loss of balance or coordination, and difficulty walking.
Sudden severe headache, with no apparent cause.

Stroke Diagnosis and Treatment

If you suspect someone has suffered a stroke, it is imperative to act quickly. The longer the delay between a CVA and treatment, the more severe the damage is likely to be. Early and accurate diagnosis is key to effective treatment and recovery.

Diagnostic tools for stroke may include:
Blood tests
Blood tests
Computerized tomography (CT) scan

Brain Neuroplasticity

Brain Neuroplasticity

Perhaps the most important characteristic of the human brain is its neuroplasticity, the ability to adapt to changes and accommodate new movement conditions. A long-held theory in the science of neurology is that the brain is divided into different parts, each responsible for a particular function, but this is not entirely true.

Contrary to popular thought, the brain is not a passive organ made up of distinct functional units, each controlling a specific function of human movement. It is a dynamic organ with different parts responsible for specific regulatory functions, but only when environmental conditions are familiar to the individual.

When a drastic change in environmental conditions for movement occur, parts of the brain that are normally responsible for a particular function can alter their function, so that the entire brain is able to adapt to new movement conditions or challenges.

NYDNRehab Virtual Reality Center for Rehabilitation

We have made significant progress in the treatment and rehabilitation of neurological diseases in the past ten years. With the advancement of technology, we are able to better understand brain plasticity, and neurological rehab has been greatly improved by integrating technology into the rehabilitation process.

NYDNRehab is proud to be a leader in the rehabilitation of neurological disease in the United States. Our Virtual Reality Center is the first private VR neurorehab center in the country, and the first VR rehabilitation center in NYC.

Brain Neuroplasticity

C.A.R.E.N, our computer assisted rehabilitation environment, is the first private system of its kind in NYC, and one of few in the country. C.A.R.E.N has been used for over 8 years in military rehabilitation centers, and in research universities conducting studies to find new and more effective ways to help patients recover from brain damage. VR rehabilitation has been at the forefront of neurorehabilitation in the last five years, and is now finally reaching patients affected by neurological disorders.

When people suffer brain injuries, it can be a traumatic experience to reenter a dynamic world with uneven surfaces, physical obstacles, and immense psychological and emotional pressures. VR immersion allows stroke patients to be treated in a fully controlled environment.

C.A.R.E.N Treatment for Stroke Recovery

C.A.R.E.N’s immersive multi-sensory environment allows patients to perform complex motor activities under the supervision and guidance of our neurological experts, safely taking their first steps toward recovery from virtual to reality.


C.A.R.E.N consists of a moving platform with a high-tech motion capture system that can be used for diagnosis and rehabilitation of balance and motor control. Gait retraining is one of the most unique features of the C.A.R.E.N system. The combination of C.A.R.E.N’s moving platform and its virtual reality multisensory immersive environment provides real-life challenges for patients in a controlled and safe environment.

During a C.A.R.E.N session, the patient is surrounded by a 180º hemispherical screen where an active virtual environment is projected, allowing the patient to be completely immersed in a versatile multi-sensory, real-time virtual environment. C.A.R.E.N helps stroke patients with rehabilitation of walking, weight bearing, and balance, far beyond what was possible before.

Recent scientific literature has established that VR rehabilitation of the upper extremities is highly effective and evidence-based.

Successful treatment with C.A.R.E.N is due to the system’s extraordinary features:
Immersive Environment

Immersive environment techniques manipulate the interaction of the patient with new virtual conditions, to facilitate the learning process in both virtual and real environments. The patient is able to develop new movement strategies and unlearn poor movement habits acquired after brain damage.

Dynamic Effect

Directing the patient’s attention externally to the effects of the movement rather than to the movement itself (internal focus), contributes to rapid recovery.

Motor Imagery

Motor imagery provides access to brain pathways responsible for memory of movement patterns stored in the brain prior to the CVA.

Walking and Movement Parameters

All gait and other movement parameters are on display in real time, for monitoring and intervention. This feature, once available only in research labs, is now offered by C.A.R.E.N.

Dynamic Control of Center of Mass

The patient learns to steer external objects using their center of mass (COM) while inside the immersive environment.

Dynamic Balance Training

The patient is able to retrain spatial awareness of their body’s position relative to gravity.

DDRobotech for Restoring Strength and Neuro-Motor Pathways


DDRobotech (DDR) is robotic training equipment powered by artificial intelligence (AI). DDR provides neuromuscular and neurocognitive training for stroke patients, to restore control and mobility in the lower kinetic chain (hips, knees, ankles and feet). DDR is based on linear force impedance robotic technology.


DDRobotec improves both physical and cognitive fitness, enhancing strength, balance and walking speed in a fun and motivating way. Training intensity, duration and cognitive engagement are precisely measured, monitored and controlled, giving us quantitative baseline data to design individualized treatment protocols and measure progress.

DDRobotech and C.A.R.E.N each have unique features that, when combined, create a dynamic duo of complementary and highly effective therapy tools, to help stroke survivors reach new heights of recovery that were previously unheard of.

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.
