Hand Movements

 
 

Bradykinesia / Hypokinesia

  • Bradykinesia refers to progressive slowness of movement, while hypokinesia refers to progressive smallness of movements.
  • These findings are decremental, meaning that they worsen as they are repeated.
    • How to Perform

      Ask the patient to perform a variety of tasks as rapidly as possible:
    • Opening and closing the hand
    • Tapping the thumb and index fingers together
    • Pronating and supinating the hand
    • Look For

    • Progressive slowing and smallness of movement with repetition of the task.

Micrographia

    • How to Perform

    • Ask the patient to write a sentence on a piece of paper.
    • Interpretation

    • Classically, patients with Parkinsonism will start writing a sentence normally, and during the sentence their writing will become smaller and smaller, due to bradykinesia and hypokinesia.
