Tremor is an unintentional, recurring muscle contraction that causes shaking movements in one or more parts of the body. It can occur during movement, such as writing or reaching for something (action tremor), or while someone is relaxed and sitting or lying down (rest tremor). These help reduce overactivation in the motor control circuits of the brain.
Clinical Trials
Tremor is a neurological condition characterized by involuntary shaking or trembling movements, commonly affecting the hands, and can occur on its own or as a symptom of other disorders. There are various types of tremors, including essential tremor, dystonic tremor, and Parkinsonian tremor, each with distinct causes and characteristics. While there is no cure, treatments such as medications and surgical options exist to manage symptoms and improve quality of life. The electrophysiological characterization of hand tremors is a useful method to complement the history and physical exam of tremor patients. The necessary equipment includes two one-axis accelerometers and four-channel electromyography (EMG). The hand tremor is recorded at rest, posture with and without weight loading, and during movement (kinetic).
What’s the treatment?
Learn the key differences in symptoms, frequency, and treatment approaches between essential tremor and dystonic tremor, including when the two conditions overlap and how to tell them apart. Essential tremor is one of the most common movement disorders. It often begins during adolescence or in middle age (40–50 years old). Dystonic tremor isn’t just a symptom—it’s a neurological expression of disorganized motor control. By addressing the underlying sensorimotor miscommunication that also causes dystonic tremor national institute of neurological disorders and stroke spasms, our integrative protocol supports the brain’s ability to re-establish smoother, more functional motor output. The appropriate treatment depends on accurate diagnosis of the cause.
- Although tremor is not life-threatening, it can be embarrassing to some people and make it harder to perform daily tasks.
- It happens when nerve cells in the brain don’t produce enough of a brain chemical called dopamine.
- As symptoms get worse, people with the disease may have trouble walking, talking, or doing simple tasks.
- While conventional treatments may help manage symptoms, they do not foster the long-term neurological recovery that’s possible through targeted neuroplasticity—the foundation of our approach.
Distinguishing between dystonic tremor and essential tremor is crucial for accurate diagnosis and treatment. Understanding the root cause of dystonic tremor—as part of a broader dystonia disorder—opens the door to more personalized and effective care. Therefore, interventions that modulate these neural pathways can benefit both spasms and tremors. This program takes a holistic approach to managing dystonic tremors by combining sensory retraining, nervous system regulation, and targeted neuroplasticity exercises designed to support lasting improvement.
- Our Dystonia Recovery Program goes beyond symptom suppression, offering a transformative path for those seeking relief through science-backed, alternative therapies that address the true origins of dystonic movement disorders.

Dr. Walter J. Koroshetz has been fascinated by the brain and how it works from a young age. They may also order bloodwork or brain imaging to identify for any underlying causes. Sometimes tremor runs in families, which suggests that genetics could play a role. If you find that caffeine and other stimulants trigger your tremors, it may be helpful to cut them from your diet.
The NINDS sponsors research on tremor both at its facilities at the NIH and through grants to medical centers. Scientists are evaluating the effectiveness of certain drugs and searching for genes that can cause certain forms of tremor. It happens when nerve cells in the brain don’t produce enough of a brain chemical called dopamine. Sometimes it is genetic, but most cases do not seem to run in families. Exposure to chemicals in the environment might play a role.
Dystonic Tremor: Low Frequency & Irregular Rhythm
In some cases, essential tremor and dystonia can coexist, or a tremor may display features of both, making diagnosis more complex. There is no cure for most forms of tremor, but there are treatments to help manage symptoms. In some cases, the symptoms may be so mild that you do not need treatment.

Dystonic tremors are typically lower in frequency and more irregular than essential tremors. EMG studies have shown involuntary dystonic contractions in the range of 1 to 6.5 Hz, often presenting as bursts that lack the consistent rhythm seen in ET . Tremor can occur in any part of the body and becomes a problem when it interferes with daily activities. Sometimes it can be a symptom of underlying neurological disorders. Finding the right treatment depends on getting the right diagnosis of the cause. Tremor caused by another medical condition may get better or go away when you treat that condition.
Treatment

Abnormal tremor is a type of movement disorder that occurs when there’s a disruption in parts of the brain that control movement. Tremor can be a primary condition, meaning it is a medical problem on its own, or a symptom of another condition like Parkinson’s disease, stroke, or multiple sclerosis. It can also be a reaction to something external, such as certain medicines or substances.
These help provide a clearer picture of the tremor’s underlying cause. However, when shaking becomes more noticeable or makes daily tasks difficult, it might be an abnormal tremor. It’s important to know that not all tremors are abnormal. Everyone has a tiny bit of shaking in their body, called “physiologic tremor.” This tiny, barely noticeable shakiness is a result of normal processes in the body such as heartbeat and muscle activity. This type of tremor is usually so small that you can’t see it, and it doesn’t get in the way of everyday activities. Although tremor is not life-threatening, it can be embarrassing to some people and make it harder to perform daily tasks.
Anyone can get tremor, but it is most common in middle-aged and older adults. For certain types of tremor, having a family history raises your risk of getting it. It can happen on its own or be caused by another disorder. It can make it hard to do daily life tasks such as writing, typing, eating, and dressing.
