General or Other | - Others | Postural Tremor (Symptom)
Postural or action tremors occur when holding the arm or leg in one position for a period of time against gravity. This may happen when writing, holding a cup, holding the arms out, or when standing up straight.
Tremors can happen at any age but tend to be more common in older people. Everyone has some tremor when they move their hands. Stress, fatigue, anger, fear, caffeine, and cigarettes may temporarily make this type of tremor worse.
There are three main types of tremors: resting (or static) tremors, intention (or kinetic) and postural tremors.
Essential tremor is the most common tremor. It is rarely seen when the hands are not being used. It becomes most apparent when a person is trying to do something, such as reaching for an object or writing. It is not caused by an underlying disease. This type of tremor may also run in families.
Overactive thyroid, stress, anxiety, or fatigue can cause a postural tremor.
