Action tremors are involuntary shaking movements that occur during purposeful actions, such as reaching for an object or writing. Unlike resting tremors, which happen when the muscles are relaxed, action tremors are triggered by movement. They can affect various parts of the body, including the hands, arms, and head. These tremors are often associated with conditions like essential tremor or Parkinson's disease. They can vary in intensity and may impact a person's ability to perform daily tasks. Treatment options include medications, therapy, and in some cases, surgical interventions to help manage the symptoms.
