Tremor meaning

Tremors are unintentional and uncontrollable rhythmic movements of one limb or part of your body. Tremors can occur in any part of the body and at any time. They’re usually the result of a problem in the cerebellum, the part of your brain that controls muscular movement. Most tremors can’t be easily treated, but they’ll often go away on their own. It’s important to note that tremors are distinct from A muscle spasm is the involuntary contraction of a muscle. A muscle twitch is an uncontrolled fine movement of a small portion of a larger muscle. This twitch may be visible under the skin. Tremors are broadly classified as either resting tremors or action tremors. Resting tremors occur when you’re sitting or lying still. Once you begin to move around, you’ll notice that the tremor goes away. Resting tremors often affect only the hands. Action tremors occur during movement of the affected body part. Action tremors are further divided into these subclassifications: • Postural tremor. A postural tremor occurs when holding a position against gravity, such as keeping your arm or leg outstretched. • Intention tremor. An intention tremor occurs during targeted movements, such as touching your finger to your nose. • Task-specific tremor. A task-specific tremor occurs while performing tasks that require skill, such as handwriting or playing an instrument. • Kinetic tremor. A kinetic tremor occurs during voluntary movement of a body part, such as moving your wrist up and down. • Isomet...

Tremors are involuntary muscle contractions that cause body parts to tremble. Tremors in the hands are common and are often due to stress or tiredness.

However, it can also occur in other body parts, such as: • the head • the arms • the legs • the torso • the There are • Resting tremors: These occur when the muscles are relaxed, including when the hands are resting on the lap. • Action tremors: These occur when the muscles are contracted due to voluntary movement. The majority of tremors are action tremors. Sometimes, tremors can indicate an underlying health issue, especially if they are persistent or very pronounced. Tremors can be normal or could result from neurological conditions, other health problems, or medication use. Below...
