Hand Tremors with Purposeful Movement: Causes, Symptoms, and Treatment

What are Hand Tremors with Purposeful Movement?

Hand tremors with purposeful movement are involuntary shaking or trembling that occurs when the individual tries to perform a controlled action, such as picking up an object, writing, or reaching for something. These tremors can significantly affect the ability to perform fine motor tasks and daily activities.

Causes of Hand Tremors with Purposeful Movement

• Parkinson’s Disease. Tremors during purposeful movement are a hallmark of Parkinson’s disease and may worsen with tasks requiring fine motor skills.
• Essential Tremor. This condition causes shaking that is often most noticeable during purposeful movement.
• Cerebellar Disorders. Damage to the cerebellum, which coordinates voluntary movements, can result in tremors during purposeful actions.
• Multiple Sclerosis. MS can lead to tremors that occur when attempting specific movements, particularly as the disease affects coordination.

Symptoms

• Involuntary trembling of the hands when attempting controlled movements, such as reaching or grasping.
• Difficulty performing tasks that require precise control, such as writing or handling small objects.
• Tremors may improve or worsen depending on the movement or posture of the hands.

Treatment

• Medications. Beta-blockers, anticonvulsants, or Parkinson’s medications may be prescribed to reduce tremors.
• Physical and Occupational Therapy. Therapy can help individuals develop strategies to manage tremors during tasks.
• Deep Brain Stimulation (DBS). DBS is a surgical treatment that can help reduce severe tremors, especially in Parkinson’s disease or essential tremor cases.
