It is a noninvasive, single treatment that enables patients to recover rapidly and quickly return to activities of normal life (usually the next day). Essential tremor superimposes a waveform on top of an accurate movement and thus is distinct from intention tremor.

This book discusses the pathophysiology of tremor including membrane mechanisms and rodent models, the advances in genetics and the musculoskeletal models pertinent to body oscillations. It's known as an intention tremor because it occurs when people are engaging in purposeful movements, rather than a resting tremor, where the hands shake even when someone doesn't mean to move them. Action tremor is most prominent in the limbs, but can occur in the trunk, neck, lips, and tongue (Wadia et al., 2005). "This thesis focusses on the neural correlates and treatment of the neurological movement disorder essential tremor (ET). There is no established pharmacological treatment for an intention tremor, several drugs have been found to have positive effects on intention tremors and are used as treatment by many neuro consultants.
