Tremor is most commonly classified by its appearance and cause or origin. Top What are the different categories or types of tremor? Isometric tremor occurs during a voluntary muscle contraction that is not accompanied by any movement such as holding a heavy book or a dumbbell in the same position.Task-specific tremor only appears when performing highly-skilled, goal-oriented tasks such as handwriting or speaking.Typically the tremor will become worse as an individual gets closer to their target. Intention tremor is produced with purposeful movement toward a target, such as lifting a finger to touch the nose.Kinetic tremor is associated with any voluntary movement, such as moving the wrists up and down or closing and opening the eyes.Postural tremor occurs when a person maintains a position against gravity, such as holding the arms outstretched.There are several sub-classifications of action tremor, many of which overlap. Most types of tremor are considered action tremor. This type of tremor is often seen in people with Parkinson’s disease and is called a “pillrolling” tremor because the circular finger and hand movements resemble rolling of small objects or pills in the hand.Īction tremor occurs with the voluntary movement of a muscle. Often, the tremor only affects the hand or fingers. With this disorder, a person’s hands, arms, or legs may shake even when they are at rest. Resting tremor occurs when the muscle is relaxed, such as when the hands are resting on the lap. Tremor can be classified into two main categories: Some tremor may be triggered by or become worse during times of stress or strong emotion, when an individual is physically exhausted, or when a person is in certain postures or makes certain movements. problems holding and controlling utensils, such as a spoon.a rhythmic shaking in the hands, arms, head, legs, or torso.the use of certain medicines (particular asthma medication, amphetamines, caffeine, corticosteroids, and drugs used for certain psychiatric and neurological disorders).neurodegenerative diseases that affect parts of the brain (e.g., Parkinson's disease).Tremor can occur on its own or be a symptom associated with a number of neurological disorders, including: Most types of tremor have no known cause, although there are some forms that appear to be inherited and run in families. Generally, tremor is caused by a problem in the deep parts of the brain that control movements. However, it can be embarrassing and even disabling, making it difficult or even impossible to perform work and daily life tasks. The disorder generally affects men and women equally. Tremor is most common among middle-aged and older adults, although it can occur at any age.
It can occur sporadically (on its own) or happen as a result of another disorder. Tremor may be intermittent (occurring at separate times, with breaks) or constant. It is a common movement disorder that most often affects the hands but can also occur in the arms, head, vocal cords, torso, and legs. Tremor is an involuntary, rhythmic muscle contraction leading to shaking movements in one or more parts of the body.
