KEY POINTS: HAND DEXTERITY & MOTOR FUNCTION

• Aging is characterized by a decline in manual dexterity, and may be quantified by decreased grip force, decreased tapping frequency, and prolonged timing for the pegboard test.
• Reports from static motor function studies on individual fingers show that the lower maximum pinch force in older adults is greatly reduced, compared with young adults.¹
  • Pinch force is a precision grip whereby an object is pinched in three ways: lateral pinch, three-point pinch, and two-point pinch.
• ...
