Tremor Symptoms and Causes
Tremor is a rhythmic, involuntary muscular contraction characterized by oscillations (to-and-fro movements) of a part of the body. The most common of all involuntary movements, tremor presents classic symptoms that can affect various body parts such as the hands, head, facial structures, trunk and legs. Most tremors occur in the hands, often resulting in loss of manual dexterity or clumsiness. In addition, tremor symptoms also affect the vocal cords, giving speech a shaky, quivering quality and can manifest in slow, voluntary movements and unsteadiness or shaking of legs while standing. Since tremor often accompanies neurological disorders, the accurate determination of the specific causes of tremor is important in choosing the appropriate treatment.
