What are Tremors?

A tremor is an involuntary, rhythmic muscular contraction that causes shaking in one or more body parts. It’s a common movement condition that usually affects the hands, but it can also affect the arms, head, vocal cords, torso, and legs. A tremor can be intermittent (happening at different times with breaks) or continual (happening all of the time). It might happen randomly (on its own) or as a result of another condition.

Tremors are more frequent in middle-aged and older people, but it can affect anyone at any age. Men and women are both affected equally by the condition.

Tremors are not a life-threatening condition. It can, however, be humiliating and even crippling, making job and everyday life activities difficult or impossible.

Signs & Symptoms

  • a rhythmic shaking in the hands, arms, head, legs, or torso

Some tremors are triggered or worsened by stress or strong emotion, physical exhaustion, or when a person is in specific postures or movements.
