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: Could occur with any voluntary movement. It is further classified into:
- Postural Tremor:
- Kinetic Tremor:
- Simple kinetic:
- Intentional tremor:
- Isometric tremor:
- Task-induced tremor:
