Overview

Tremor may be classified into resting or action tremor. Action tremor includes postural, kinetic (simple or intentional), isometric and task-specific tremor.

Classification

Tremor may be classified into two main groups:

• Resting tremor: Occurs when the body is not moving and is at rest. It could occur in hands, legs, or arms. Resting tremor decreases in intensity with targeted movement. Parkinson's disease and drug-induced parkinsonism exhibit resting tremors.
• Action Tremor: Further classified into
